During the process of building a house, many owners have a question about when to install windows. It is important to know that designs from natural wood installed after completion of internal finishing works such as screeding ceilings and plastering.
Before installation, the building must dry out a little, since high air humidity can lead to swelling of the natural material and its cracking, as well as damage to the paintwork.
You can reduce air humidity by using gypsum board to decorate walls instead of plastering. In this case, the installation of the window structure can be carried out after screeding the walls and before finishing with gypsum board.
If you prefer plastic windows for your home, they can be installed both after and before finishing, since PVC construction is not susceptible to moisture. However, it is important to remember that if the walls are finished with plasterboard, the windows must be installed before using it, since the material is not moisture resistant.
Carrying out work in winter: basic details
The main construction processes: laying the foundation, erecting walls, organizing the roof occur during the warm period of the year. In autumn and winter it is time for interior finishing work. After installation metal-plastic windows The heating system in the house needs to be started. In winter, it is recommended to use plasterboard sheets for wall decoration. The choice of this material does not greatly affect the level of humidity in the room, but will significantly speed up the repair work.
If the owners plan to install windows made of natural wood, dry plaster is used for finishing work to avoid swelling of the frames.
The key to success: the correct microclimate in the room being renovated
The speed and quality of work largely depend on humidity and temperature. In houses where they are installed plastic windows, it is necessary to improve the natural ventilation system. To do this, the windows are left slightly open, and ventilation ducts fans are installed.
It is also necessary to control the temperature. Until the screed and plaster are completely dry, the value on the thermometer should not fall below +5°C. As an alternative to traditional concrete screed You can partially use dry prefabricated. This choice will speed up the finishing work by reducing the amount of construction moisture.
We carry out finishing work in the summer
Interior decoration is an important and time-consuming process. Before starting repairs, it is advisable to complete the installation of plastic windows. Especially if the work is planned for spring period.
Window installation involves several stages. Upon completion of installation, repairs and leveling of slopes are carried out. Then they begin to treat the walls with cement mortar.
Installation of wooden windows should be postponed until the interior work is completed.
It is important to remember that a draft causes the wallpaper to peel off and causes the paint to “swell.” You can protect the room from air penetration using film. It is enough to fix it on window opening.
The slopes must dry after finishing work. Therefore on initial stage, the solution should only be applied to walls. Wooden windows are installed last.
At the final stage, the window slopes should be plastered. Craftsmen also use an alternative cladding method - finishing them with plasterboard.
On walls that are not insulated in any way, the facade can be plastered both before and after installing windows. However, it is still recommended to carry out the work after the windows are installed. This will allow you to carry out all subsequent finishing work faster and more efficiently. After installing the windows, slopes and external sills can be installed immediately. These works make it possible to avoid further alterations to the façade. If the plaster was applied before installing the windows, then the subsequent plastering of the facade will be very different.
If the plans include the organization of two-layer walls, then initially they carry out
installing windows, and then laying insulation and plastering the facade. In addition, this order of installation allows for better finishing work.
external slopes.
So that after insulating the facade it is possible to apply plaster, slabs
apply 2-3 cm to the window opening. It should not be allowed to be in the corners
windows formed joints from insulation boards. Therefore, the slabs are cut, giving them
"G" shape. And then they attach it with a cutout in the corner of the window.
During the period of plastering the facades, specialists cover the windows with film, which is secured with adhesive tape. Upon completion of work it is removed. It is not recommended to secure the film with masking tape, since after removing it, marks will remain on the window.
Construction installation rules
When ordering windows, you must invite a company specialist who will accurately measure the dimensions of the future structure.
The product is installed at an outside air temperature of at least -5°C. Lower values can lead to the appearance of microcracks and chips on plastic elements window. In addition, negative temperatures lead to deterioration in the adhesion of polyurethane foam to the wall.
Fixing the window structure to the wall
The window is mounted in the opening using special bars, aligned in the vertical and horizontal directions. It is fixed to the wall using one of two methods - frame dowels and steel anchors.
If an anchor is used, one end of it is fixed to the window and the other to the wall. Such fasteners can be used to fix window blocks made of various materials.
The frame dowel is not such a universal solution, since it forces changes to the design. To fix the frame with its help, a hole is drilled in the window profile and the wall. A dowel is installed into the formed channel and screwed. All work is carried out by installers carefully, since tightening the dowel too much can lead to deformation of the window.
Upon completion of the installation of the window structure, the joints along its perimeter are foamed, and the outside material is protected with vapor barrier tape or a special liquid sealant. It allows you to prevent the influence of negative external factors on the foam.
Placing a window in a wall
It is necessary to correctly position the structure in the outer wall, as this will prevent the appearance of “cold bridges”.
When installing the structure in a single-layer wall, it is placed closer to the middle, which reduces heat loss. In double-layer walls window unit mounted flush with the outer part of the masonry. In this case, it is important that the insulation extends onto the profile at a distance of about 3 cm, covering the joint between the wall and the frame.
In the case of building a house with three-layer walls, the window structure is mounted in the insulating layer, in close proximity to the masonry of the load-bearing part of the wall. The resulting gap is filled special tape, preventing the negative effects of moisture and temperature changes on the structure.
Installation of window units in winter is complicated by low temperatures and high humidity. It is necessary to somehow neutralize these negative conditions. To do this, installers can use two methods for winter installation of double-glazed windows.
The simplest winter installation
As stated above, in winter time Some nuances must be observed in accordance with the seasons.
In the cold season, frost-resistant polyurethane foam must be used to seal joints.
- Firstly, for sealing you need to use polyurethane foam with frost-resistant components in the composition.
- Secondly, in the cold season, a “heat” gun is used when foaming joints. It is used to warm up the layer of applied foam on the street side. And only then do they start filling the gaps from the inside with foam. This is done to ensure that all voids are properly filled with sealant (foam).
- Thirdly, this step-by-step installation. That is, having dismantled the old one, they immediately installed a new one, and so on one by one, working with each opening.
- Fourthly, the mounting tape is attached in warm conditions. If possibilities allow, then before removing the old ones.
- And fifthly, the hydro- and vapor barrier tape (PSUL) is also heated by a “heat” gun during installation.
Using a heat gun, the joint surfaces and PSUL tape are heated
This is the most basic “winter” technology for installing double-glazed windows, without which it is impossible to obtain a high-quality result.
Warm installation
The use of this technology will increase the cost of installing windows, but its use can smooth out the conditions of the winter season.
Scheme warm installation
What does the technology of warm installation of plastic windows provide?
- Warm installation of windows is a mandatory external sealing of the opening. To protect the installation site, it is fixed to the opening from the street side. protective screen. A heat shield for installing windows holds back the heated air in the room and prevents the installed double-glazed windows from freezing. In addition, such protection will not allow excess moisture to enter.
- For compaction, as with conventional winter installations, frost-resistant polyurethane foam is used.
- Compliance with internal sealing of the joints between the frame and the opening is mandatory. Inside there is silicone (a sealant that prevents moisture from entering). The middle layer will be polyurethane foam, which acts as a sealant and insulates the joint. From the outside, all gaps are covered with waterproof tape.
Installation of windows in winter involves a work algorithm similar to the usual one for installation in the warm season:
- The opening closes;
- dismantling old frames;
- preparation of the opening surface;
- installation work;
- finishing of slopes.
The protective screen ensures reliable and high-quality installation of PVC windows in winter
The use of warm installation technology is more preferable in winter. A protective screen in combination with materials will ensure better installation without additional risks (destruction of the seal, the appearance of mold and mildew) in any type of building (brick, panel or block house) . In addition, the use of triple protection during warm installation will increase the tightness, which will reduce heating costs.
Why installing windows in winter is not always possible.
When installing window structures today, foam is most often used. Its peculiarity is expansion in air at certain humidity and temperature parameters. This gives rise to restrictions related to ensuring the required conditions. In terms of temperatures at which polyurethane foam expands properly, until relatively recently, installation in winter was basically impossible.
Today there are already some technologies that allow you to install windows in almost any weather. Such know-how includes special fencing for window openings, similar to a heat screen, which allows you to increase the ambient temperature. Other alternatives are the use of special winter foam kits.
Despite the obvious advantage of using the latter, it is still possible to speak with a fairly high degree of confidence about their reliable operation at temperatures not lower than -150C.
Thus, as we see, each window replacement season has its own advantages and disadvantages.
Sequence of checking installed plastic windows
In fact, there is nothing complicated about this, and you should be guided primarily by your subjective feelings
First of all, pay attention to whether the room became significantly warmer immediately after installation. After this, carefully inspect the window to see if everything is done neatly, and if there are any noticeable cosmetic defects that would embarrass you in front of your guests.
Make sure that there are no noticeable scratches on the glass and the plastic itself, and that the frame is not deformed. Of course, the polyurethane foam should not protrude anywhere, because it itself does not look particularly aesthetically pleasing, and in addition, over time it can acquire a brown tint. Remaining foam must be thoroughly cleaned both inside and outside.
To check the quality of installation of fittings, you should make sure that the window sashes open easily and their movement is sufficiently soft in any operating position. To check the tightness of the fit, you can clamp an ordinary sheet of paper with the window sash and make sure that it is clamped well enough and cannot be pulled out.
If you have the skills to use a level, be sure to measure the quality of the installation using it. In addition, the contract must stipulate that the company undertakes to correct all defects discovered during operation at its own expense.
After a few days, you should carefully inspect the inside of the frame when good lighting. Even a slight coating of dust indicates that the seal of the window has been broken somewhere nearby.
Selecting the season for installation
So what time of year is best to do this? In fact, there are many pros and cons to installing windows in summer and winter. Let's look at each in more detail.
Installation of a plastic profile in summer
If the renovation of an apartment is carried out in the warm season, then replacement of windows should be carried out before finishing. And this has a significant advantage. In summer, you can open the doors and dry the room, remove odors building materials. And most people prefer to complete this process before the cold weather sets in. Therefore, it is during the period from spring to autumn that there is a real boom in such services.
Winter installation
Many will be surprised, but when it comes to installing double-glazed windows, winter time has many more advantages.
First of all, during installation, all the problems of the room are immediately noticeable: drafts, freezing, wall features. An experienced master will immediately notice all this and eliminate it with the help of high-quality replacement of window structures.
Another advantage worth installing similar products It is in the cold that prices are reduced during this period, as well as all kinds of promotions.
The only possible drawback that exists is the difficulty of installation when it is minus 15 or lower outside. In this case, you will need to use special frost-resistant polyurethane foam.
Unpleasant features of winter window installation
Of course, not a single serious event is complete without its downsides. The same situation applies to winter window installation. The main disadvantage is that during installation the room will become really cold, because the window will be wide open (or rather, completely absent) for at least 30 minutes. Therefore, you should remove pets, an aquarium, flowers and electronics, which are often forgotten, from the room.
In the summer, this problem is not relevant, and therefore the procedure is very different, primarily in that all the old windows are first dismantled, and then plastic ones are installed one by one. In winter, this cannot be done; dismantling of the next window begins only after the previous one has been completely installed. When signing the contract, do not forget to clarify whether the installers will adhere to this approach.
How quickly do our craftsmen install windows?
Some of our clients are concerned about the issue of heat preservation during installation work. We hasten to assure you that in winter it will not affect the temperature of your apartment in any way. Because everything preparatory work are produced in a warm place, the installation procedure itself takes about 30-60 minutes, which can be compared with conventional ventilation.
Thus, dismantling a conventional three-leaf window takes our specialists about 10-15 minutes. The rough installation of the block with its fixation in the opening and hanging of the sashes takes approximately the same amount of time. In fact, the doorway remains completely open for no more than 20 minutes, and during this time the temperature in the room manages to drop by a maximum of 5-10 degrees. C. It will take some more time to seal the installation seams. If you decide to install windows in the entire apartment at once in winter, then in this case the procedure involves sequential installation, during which the house does not have time to freeze.
The process of winter installation of plastic windows
First of all, the old window is dismantled. As noted above, in winter, the entire work process is carried out on each window separately and sequentially. The cleared opening is cleared of the remains of the old structure, plaster, debris and snow. The surface of the opening is processed and heated with a hairdryer for better adhesion of the polyurethane foam.
The frame of the future window is installed in the opening, positioned strictly vertically, and then fixed using special fasteners. In this case, it is necessary to carefully monitor the width of the gap between the opening and the window; it should be strictly within the range of 15-30 mm.
The entire surface to be treated is moistened with water, after which it is “blown out” on both sides with polyurethane foam. When installing in the cold season of the year, of course, special winter foam is used. After swelling and filling all the cracks, the foam will take several hours to harden.
A flashing is installed on the outside of the window, and it is mounted so that water does not get inside the window during rain. During installation inner part The windows are fixed with special spacers so that the expanding foam does not deform or damage the frame.
Cosmetic finishing of installed windows
It takes two to four hours to completely install a window. After the foam has hardened and stopped expanding, you can begin exterior decoration joints The joints are additionally sealed and plastered. Only after this the fittings are installed and adjusted.
Using a sealing tape, the polyurethane foam is protected from the sun and moisture; if necessary, additional processing is carried out silicone sealant or plaster. Of course, during the finishing process it is necessary to constantly monitor whether the window sashes open normally and move easily in all working positions.
When the work is completed and appearance you are satisfied with the windows, you need to check them carefully, and then sign the acceptance certificate. This is a very important moment, since in the future you will no longer be able to make complaints if they suddenly arise
By the way, few people know how to properly check a newly installed window, and what to pay attention to first. Let's take a closer look at this process
Is it dangerous to cool the apartment during installation?
It is clear that at the moment when the old window has already been removed and the new one has not yet been installed, there will be a lot of people leaving the apartment. warm air. Many homeowners are afraid of expensive renovations in their apartment, since materials for interior decoration usually not designed for use in sub-zero temperatures.
However, there will be no sub-zero temperature in the room. The fact is that the opening will remain open for no more than half an hour, and even then, at the request of the customer, it can be covered with film. And then they will put a plastic window in place, and the air will only blow into the narrow cracks on the sides of the window until it foams. In practice, the room temperature drops by no more than 10 degrees.
However, things that are particularly capricious to temperature changes and houseplants It is better to move it to a warm room during installation.
How to determine if plastic windows are blowing
The test for the tightness of the sash is very simple - you need to pinch a sheet of paper with the sash and drag it. If the fit of the sash is good, the sheet will tear and it will not be possible to pull it out. Each sash must be checked in this way from four sides.
An even simpler way to determine blowdown is by external signs. If you open the sash wide and find a layer of dust on the inside of the frame (rebate), it means the window is not airtight enough. In this case, you should urgently call a specialist to carry out repair work.
So, winter installation of plastic windows is quite acceptable, and even beneficial for the customer. quality control of work is required regardless of the season. The customer does not need to take any special measures to protect the apartment from frost.
Are there any advantages to installing windows in winter?
If you are not tied to the timing of construction or repairs, then winter will be beneficial for several reasons:
- The correctness of the installation can be assessed immediately. If the technology has been broken, or the selected windows do not differ best quality, you will immediately encounter problems such as blowing or excessive condensation. And you will be able to make claims against the company where you ordered the product and installation. Also, replacing windows in winter will help identify other problems in the room - freezing of walls, cracks in slabs, etc.
- Window manufacturers are not too busy during the cold season, so you can contact any company and be sure that your order will not be rushed and will arrive on time.
- During the winter, most companies have pre-holiday sales and offer good discounts, so you can save on your purchase or choose a better product within your budget.
As for the disadvantages of installation in winter, there are 2 main points:
- it will be cool in the house for several hours (installation + warming up after), so if there are small children in the house, it is better to send them to grandma or dress them warmly;
- It will be impossible to carry out installation at very low temperatures (from -20), so it is better to first check the weather forecast for the planned days (although there have been no severe frosts in our country in the last couple of years).
So, you see that there are no specific recommendations or restrictions on the choice of season for installing PVC windows. Both summer and winter have their advantages, so the choice is always yours. And from our company you can order high-quality plastic windows at any time of the year, and not worry about their installation!
Why are windows replaced more often in summer?
The main argument in favor of replacing windows in the summer is the fear of freezing out the apartment while work is being done. However, with modern plastic systems this problem no longer exists, because the installation process takes on average from 40 minutes to 1.5 hours. It will not take much time after installation for the room to reach the initial temperature.
When we are talking not about simple window replacement, but about repairs in general, then, of course, it is better to choose warm season. Late spring, summer and early autumn – best time for repair. The reasons are obvious: building mixtures dry faster, there is the possibility of constant ventilation of the room, longer daylight hours and other advantages. If you are setting up new house or spend major renovation apartments in the summer, then the windows need to be installed immediately, at the stage of rough finishing.
However, when installing double-glazed windows in the warm season, it is worth remembering two small nuances:
- in summer it is more difficult to detect problems - drafts, blowing, small cracks - everything that can make itself felt in winter;
- It is better to order windows in advance, since during the peak season the manufacturing process may be delayed due to the large number of orders.
Warm window installation what is it
If you are still afraid to install plastic profile in winter, it is worth paying attention to this technology. Not every person is delighted to carry out installation on a frosty sunny day.
Whatever one may say, the cold will break into the apartment even during these 25 minutes, during which the doorway remains open. And here the technology of warm mounting will be a real salvation. What is it?
This unique method does not have all the disadvantages inherent in installation at very high sub-zero temperatures. You can use it even if it is very cold outside and standard installation impossible. During warm installation, a special screen is installed in the opening, which protects the room from freezing. Let's talk more about this procedure.
As we said earlier, the opening remains open for 25 minutes. If you use this modern technology, then for such a period the master installs a special heat shield. It is fixed using detachable clamps, and there is no need to drill the walls, which means that the exterior and interior of the building will not be damaged.
Along the contour there is a pneumatic frame, which is filled with air until the entire window niche is covered with a screen. Experts tighten detachable clamps to press the protective screen as tightly as possible to the wall of the house. As a result, the cold has no chance to penetrate inside the building.
And only after this is dismantling carried out old frame followed by installation of a new double-glazed window. After the structure is installed, the screen is removed.
As a result, the apartment owner is satisfied modern window PVC and heat preservation in the room.
Where to start preparing for window replacement
The first step, of course, is to measure window openings. In any case, a company specialist will come to take measurements again, but approximate data will help you get a better price. With a specialist who comes to measure the windows, you can also discuss options for the structural design and design of the window that best suits you.
When all organizational issues have been resolved, a company has been selected, a contract has been concluded and a date has been set for installation, some preparation should be made in order to optimize this process as much as possible. Many of these things are often forgotten. Here is a list of what you should do first to avoid fuss while working:
- Prepare a place to work, remove all unnecessary things;
- Protect your floor finish by laying thick paper or cover;
- Close interior doors(from cold and dust).
Is it possible to install plastic windows in winter?
Most often, apartment owners refuse to install plastic windows in cold weather for the following reasons:
- They fear that in the process of dismantling old windows and installing new ones during frosts, damage to the heating system and freezing of the room will occur;
- There is a risk that polyvinyl chloride (PVC) windows, the most common type today, will become brittle at low temperatures. This threatens the appearance of cracks during the mechanical impact on the window, which is inevitable during installation work;
- Most often, when filling the mounting joints of a plastic window block with an opening, polyurethane foam is used. There is a risk that with low air humidity, characteristic of winter, it will freeze before it polymerizes.
Of course, such fears are indeed justified. However, in our time, such risks and possible problems Installation of plastic windows in winter can be completely prevented.
Let's start with the first reason, according to which installing windows in winter is unpopular - there is a danger of freezing the room and damaging the heating system. In fact, if the dismantling of an old window and installation of a new double-glazed window is carried out by a team of professionals, the room will be left without glazing for 30–50 minutes, maximum for an hour, because everything happens quite quickly. During this time, the room will definitely not have time to completely dry out, and the pipes will freeze.
Warm window installation technology
In addition, today the technology of warm window installation has begun to be widely used. What does it consist of: a special inflatable heat shield is installed outside the building, behind the window opening. It is attached to the outer wall around the perimeter of the old window before it is dismantled, so it will protect the room from frost and cold wind. Of course, with such a protective screen it will be more comfortable for workers to dismantle and install.
Important! Even taking into account the possibility of using a heat shield for installing new windows, this work should be carried out in winter in each room one by one. First a window in the same room with closed door, if it is not there - doorway closed with a cloth or other materials, then in another
This will prevent the appearance of drafts, which absolutely no one needs in winter.
Note that some window installers use homemade curtains from various film materials to make working indoors comfortable in winter. And you need to understand that the price of a professional heat shield for installing windows in winter is quite high.
As for the fact that PVC windows can become fragile in the cold, this problem is also not difficult to solve.
- First, you should choose a trusted manufacturer and high-quality double-glazed windows designed for significant temperature changes.
- Secondly, before installing the windows after transportation, they must be kept in a heated room so that they warm up.
What to consider
If the installation of windows takes place in an unheated house in winter, for example, a new building, which you do not want to leave with open openings during the cold season, you can also take measures. The simplest option is to pre-close the window openings with film and heat the room - with a convector, a heat gun - which is available, so that the plastic windows warm up a little after transportation.
Important! In any case, experts advise installing plastic windows at a temperature not lower than minus 25 °C! Some experts even consider minus 15 °C to be the minimum.
Now let's talk about the third factor. risk when installing plastic windows in winter - using mounting foam. Experienced repairmen sometimes simply heat this composition in a water bath before use and leave it in warm room at least overnight, warm up the areas where the foam is applied using construction hair dryers, and moisten the joints with warm water to speed up polymerization.
But even if all these measures are used, you should use special polyurethane foam designed for sub-zero temperatures. There are compounds that are “winter” and can be safely used at temperatures of minus 20 degrees. Here, it is they who should be used for winter installation of windows. Yes, winter polyurethane foam costs more, but you cannot skimp on quality and comfort.
Why the customer is willing to pay double the price
As a rule, an increase in demand is accompanied by an increase in the load on production. The workload of workshops forces window sellers to increase delivery times finished products- they are pushed by the increasing production time. Those entrepreneurs who do not want to abandon their potential clients in this way (that class of buyers who need PVC windows here and now) adjust demand by increasing the cost.
As a result, in the industry as a whole, in a given time period of 6-10 months (seasonal demand for windows sometimes begins with the first sunny days of March and ends with the arrival of cold December), customers are forced to buy windows at a higher price.
But no most of customers who decide to replace windows in winter already have the benefit that their products will most likely be cheaper.

What season is best to install plastic windows
New technological solutions appear every year, and if a decade ago experts said that plastic windows could only be installed in the warm season, now it is possible to do this when there is a special need for it.
Of course, even now there are some issues that will require special attention, but if critical events occur, plastic windows are installed at any time.
Advantages and difficulties of installing windows in winter:
- an undoubted advantage will be, which falls during the season of low demand. Some clients use this moment to buy windows in advance for the proposed renovation, and plan the actual installation for the summer;
- during installation, you can immediately check the tightness, because even a small defect will immediately manifest itself as a draft. As a result, either the defect will be eliminated immediately, or the window will be replaced with a similar one, and no further alterations will be required;
- only very severe frosts can interfere with the installation, in which even thermal screens do not help to maintain the temperature of the window opening acceptable for work. While the windows are being installed, it will be cold in the apartment, so you need to immediately plan that you will not be able to stay in the house;
- The polyurethane foam that is used when installing a window requires a certain external temperature, and humidity will also play an important role. Among the technological innovations, we can confidently highlight the presence of special foam for installing windows in winter conditions, but even here there is a limit (not lower than 15 degrees below zero).
Advantages and difficulties of summer window installation:
- comfortable temperature and low humidity will allow specialists to work much faster, and the residents themselves will be able to stay in the apartment. The window openings will be constantly open, but this will not create difficulties, because in summer it is quite warm even in the evenings;
- long daylight hours will allow you to install a window unit in one working day, all work will be done quickly. By evening, apartment residents will enjoy the view from the new window, since all work will be completed at once;
- Everyone understands the benefits of installing windows in the summer, so the demand for plastic frames rises sharply, therefore, the prices for windows will increase compared to winter or late autumn.
The most favorable period for installation of plastic windows is the last months of spring, when it is already quite warm, but there is still no rush to buy windows. If you did not purchase plastic windows in the winter, then you can purchase and install windows in the spring - it is economical and convenient in all respects.
Additional work
A prerequisite for high-quality installation both in winter and summer will be the finishing of the slopes of the window opening following installation.
Why are these needed? additional work? The main function of finishing slopes is to protect the gaps between the window and the opening from temperature changes and moisture. Foam is an excellent sealant and insulator, but it is very sensitive to ultraviolet rays and humidity. If you do not close the gaps, in a month the sealing layer will lose its properties, and by spring it will begin to collapse.
It is better to finish the slopes of a window opening with insulation
After installation work finishing works are underway. It is best to make the slopes warm, that is, with an additional layer of insulation (foam, mineral wool) . In the schematic drawing you can see one of the options for insulating the internal opening. It's not a very big cost. But in this way the thermal insulation of the window will be improved.
At what stage of repair is it better to install plastic windows
We have dealt with seasonal issues. But what to do if the renovation is already planned (or already in progress), and when is the best time to install a window is a mystery.
Experts advise installing plastic windows immediately before starting the final renovation work in the room. This will make it possible to keep the “cosmetic” renovation of the room in perfect condition and not subject the design of the new window, sometimes mercilessly and irreparably.
At the same time, the issue of installation before or after the so-called “wet” work is not so fundamental. Main - good ventilation and, in some cases, space heating.
Installing windows is a responsible and important matter. You can't do everything at random here.
If you are in doubt about the solution to a particular issue, it is always better to turn to the experts. Choose good specialists and enjoy the comfort and coziness of home in your premises. After carefully reading the article, you will be able to answer your question, when is the best time to install plastic windows.
When to install windows
Of course, it is best to do a leisurely replacement or installation in the warm season under normal weather conditions and positive temperatures. But, if the construction of a new house has been delayed, then it is also possible to install plastic windows in winter. The same applies to replacing old windows with new ones. There are some positive aspects to this season, but you need to take into account some nuances. So is it possible to install plastic windows in winter?
Benefits of winter installation
Windows in our country are a seasonal product. Most consumers try to have time to carry out installation in the spring and summer, when it is more convenient. Most often, window installation companies work under increased load during this period, so owners have to wait longer for orders to be completed.
In winter, the demand for installation and construction work drops sharply
Installing windows in winter, on the contrary, gives an advantage in the quality of order fulfillment. Most construction work, including window installation, is less in demand during the cold season. At this time, you can find interesting offers for the manufacture and installation window systems: promotions, discounts and others. In addition, the installers will not rush, since the schedule is not so tight, which will affect the quality of the installation. These are the main advantages with which you should not be afraid to install windows in winter.
Nuances of the cold season
It is important to consider at what temperature the installation is carried out. It is prohibited to install plastic windows in winter at temperatures below -20 degrees
In this case, construction foam, which is used as a sealant, will contain a large number of ice crystals, and the quality of such an installation will be much lower. And after a while, there will be such consequences as freezing and mold.
Also, if there is too much frost (-15 and below), the seals of opening windows become less elastic, which can lead to poor adjustment of the sashes.
The sealant for PVC windows loses its quality during installation work at temperatures below 15 degrees
If you are planning a winter installation of plastic windows in a new building, then permissible temperatures air, all work can be carried out without problems.
Another thing is the replacement in residential premises. It is worth considering that installation time is 30-40 minutes for each double-glazed window, and the rooms will cool down. To do this, unlike in the summer, you need to dismantle and replace double-glazed windows in stages.
In winter, after the delivery of double-glazed windows, they need to be kept in the house for 24 hours at room temperature so that all elements warm up. This is done in order to avoid thermal deformations..
Another option for winter installation is to carry out the so-called warm installation of window systems.
The order of work during the construction of a house is clearly defined, and it is better to strictly adhere to it. And this applies to eurowindows, both plastic and wooden. At what stage of construction is it better to install windows, and what will be the consequences of installing translucent structures at another time, the WINDOWS MEDIA portal will tell you.
A common practice in domestic private construction is to install windows just before winter in bare walls in order to close the inner shell and be able to carry out finishing work, usually wet and dirty. This is a common mistake in the art of building.
Irreversible consequences of "amateur" in the installation of windows
Ideally, if the installation of windows and doors will be carried out after completing and drying the screed and interior plaster but before laying the insulation outer wall. This sequence of work will ensure that the insulation layer around the windows does not accumulate excess moisture (which in winter will lead to condensation in the insulation layer, further freezing in the foam layer, and, consequently, degradation of the cellular structure of the polyurethane foam).
When wooden windows excess moisture can cause window frames to swell, paint surface cracks, and even frame joints, as well as corrosion of hardware components. Recall that windows are designed for "normal" operating conditions, which fluctuate around an internal temperature of 20 degrees Celsius and relative humidity in the range of 50-60%. Very often, the provision of just such conditions of use is the starting point of the guarantee documents of eurowindow manufacturers.
At what stage of construction should Euro windows be installed?
Wooden windows. It is better to install them after completing “wet” work inside the house. If you install them first, then high level indoor humidity (about 90%) can cause irreparable damage to wooden frames. Although manufacturers claim that modern wooden windows are resistant to moisture from precipitation and do not deform, they do not recommend their installation before plastering and screeding. Some of them even warn that the guarantee offered for euro windows made of wood loses its relevance if, after the installation of joinery, "wet" work was carried out in damp, inefficiently ventilated and poorly heated rooms.
PVC windows. It does not matter whether their installation is planned before or after “wet” work. Should always provide effective ventilation premises (if necessary, and heating), so that moisture does not condense on the surface of the double-glazed window, because it can then go to the slope and subsequently provoke the appearance of mold.
“Wet” work in winter. Often construction work is completed at the end of autumn and the installation of windows and finishing work fall into the winter period. In this situation, it would be better to choose plastic windows, which in principle can be installed at any time of the year (although days when the temperature drops below -5 ° C should be avoided, even if winter polyurethane foam is used for sealing, which can work at temperatures up to - 10 °C). If the winter is cold, it is best to postpone the installation of plastic windows for the spring. Very low temperatures will cause the PVC to become brittle, which can lead to cracking of the profile during transport, unloading and installation.

With the installation of wooden eurowindows, it is also better to wait until spring. However, if Euro-windows have already been installed, and there is a desire to finish the house in winter, it is worth considering whether wet work should be replaced with dry work. Laying plasterboard and plasterboards does not have a big impact on the humidity in the room, and also does not delay further finishing work. When work is interrupted for the winter, and the windows have already been installed, it is important to ensure ventilation in the rooms, otherwise the accumulated moisture will condense inside the house - most likely on the windows.
The most useful sequence of work when installing eurowindows
Thanks to this sequence, it will be possible to avoid contamination or damage to the window, high humidity in the house, and unnecessary duplication of work (correction of previously completed slopes damaged during window installation).
Installation of windows before or after plastering
Before plastering. If the finishing work will be carried out in the spring and summer, the windows can be installed before the “wet” work. They must be shielded protective film or during plastering, the sash can be removed and the frames carefully protected. You can also install windows, plaster the slopes and corners, and then, having protected the windows with a special film, plaster the remaining surfaces of the walls. Applying plaster requires temperatures above 5 °C, so when planning this work for the winter (especially gypsum plaster), eurowindows should be installed earlier. This sequence of work is acceptable if you decide to install plastic windows.
With the installation of wooden windows, it is better to wait until the plaster has completely dried. If windows are installed in the fall before plastering, they should be carefully screened with film and left open to allow moisture to be removed.
After plastering. It is best to plaster the walls inside, leaving the slopes and corners unplastered. After they dry, the windows are installed, and after the foam has dried and hardened, the slopes are plastered. This approach is especially appropriate in the case of wooden windows. Then it is possible to avoid their possible contact with excess moisture from drying out the plaster.
It happens, however, that plasterers do not want to agree to complete the slopes. If you plan to install plasterboard, then a team of plasterboard installers can help with finishing the window opening. After installing the window, cut plasterboard slabs are glued to the opening in a certain way. You can, of course, completely plaster the walls and slopes, but after that it will be difficult to install windows without damaging the plaster.
Installing a window after performing “wet” work in interiors has another advantage: the surface of the frame and double-glazed windows are not subject to contamination, scratches and irreversible damage by workers of another construction team. Unfortunately, there is a risk of not avoiding this when installing insulation around a window frame or sill. Therefore, before starting insulation work, you should protect the window along with the frames with a layer of special film.
Many people are interested in the question: is it possible to install windows in winter? And really, is it possible? In fact, not everyone thinks about this. As a rule, when the opportunity arises to change the windows to more modern ones, then they do it. And in winter you can still get a discount, because the companies that do this don’t have many orders during the cold period. Also, the windows themselves will be manufactured faster for the reasons stated above. In general, everything seems to indicate that there is no need to wait for the warm season. Well, of course, the house will be cold during installation, but then you can warm everything up. It doesn't seem to be a problem. In addition, if the installers know their job, the work will be completed promptly.
But is this really so? In this article we are going to raise the question - is it possible to install plastic windows in winter?

Installation of plastic windows in winter
Do they install windows in winter? There is a myth circulating on the Internet that installing plastic windows in winter is strictly prohibited. Many people willingly believe in this, without going into details. For most, the main thing is that everything works for a long time and does not create problems. And asking some unnecessary questions is unnecessary.
However, there is one small “but” - In winter, plastic windows can be installed. Nobody forbids you to do this. Even according to GOST this is allowed. Of course, there are some nuances and rules. If you follow them, then no problems will arise. There are recommendations from the window manufacturer, and experienced installers are also aware of them.
For example, a window that has just been delivered cannot be installed. Why? The fact is that in the cold, plastic tends to shrink. After installation, the window will heat up from the room and may leak. That is why, before installation, it is necessary to metal-plastic structures We lay in a warm room for some time.
Is it possible to install plastic windows in winter? Yes, but not at -15 degrees. Why not? It's a rubber seal issue. In the cold it will stiffen, and it will be very difficult for installers to make an accurate connection of the sash. Although, on the other hand, if the double-glazed window warms up in the room, it is unlikely that it will freeze that much even with the window opening open. Therefore, in principle, there is nothing to worry about.
Another thing is cooling the apartment. After all, during installation you will have to completely open the window opening.
Is it dangerous to cool an apartment when installing windows in the winter?
But really, what should we do about it? Even the most efficient craftsmen will not be able to do the job so quickly as not to cool the room. Right? With an open window, the room will become colder every second. So?
Many owners first begin to worry about their expensive repairs. After all, most materials intended for interior decoration are not suitable for use in subzero temperatures. That is why a logical question arises: “Is it worth installing plastic windows in winter?”
All this looks like horror stories that for some reason scare gullible citizens. Where should the sub-zero temperature come from in the room? After the old window is dismantled, the film is immediately stretched in its place. The door to the room is closed. Work with a fully open opening lasts no more than 30 minutes. In practice, the temperature in the room drops by only 10 degrees. If you don’t want this either, you can simply turn on the fan heater, and then the temperature regime will remain without much change.
Winter installation and its quality
In fact, the quality of installation, both in winter and in summer, depends mainly on the experience of the craftsmen carrying out repair work. Also, do not forget about the quality of the materials used. But the question is definitely not appropriate here: at what temperature are windows installed in winter? From all this it follows that problems may begin with windows installed in the summer within a month, and metal-plastic structures installed in the winter will serve faithfully for many years. Or maybe everything will be the other way around.
In general, installation of plastic windows in winter is not much different from work carried out in the warm season. Although there are still some nuances:
- First you need to dismantle the old windows.
- Then comes the preparation of the opening: cleaning it from ice, snow and dirt, heating it with a hairdryer. The latter is done for better adhesion of the polyurethane foam to the surface.
- Installation of the box.
- Foaming. In this case, special frost-resistant polyurethane foam is used.
- Insulation of slopes.
- Window sill installation.
- Equipping windows with fittings and adjusting them.
- It is advisable that the temperature outside is not below -15 degrees.
Window testing
After installing a window, every owner considers it his duty to check its operation. And it is right. You need to make sure that plastic windows can be installed in winter. By the way, it is worth noting that checking the operation of windows in cold weather is much easier. After all, it’s warm inside and cold outside. You can immediately feel whether it is blowing or not.
So, first you should check the window for tightness. For this you will need a regular A4 sheet. You need to pinch it with the sash and then try to pull it out. Naturally, the attempt should not be successful. The sash should be checked on each side.
You can find out if it is blowing from a window using an ordinary candle. Set it on fire and drive around the perimeter. If there is a delay somewhere, then the installers should not be released.
Important! The window should close tightly, there should be no blowing from it, and the sash should not catch anything. If noise continues to be heard from the street, then, most likely, an installation error was made.
But to once again Don’t worry, you should contact a company that has already proven itself on this issue.
Results
When is it better to install windows: winter or summer? Whenever is convenient for you. In winter, you can "run into" a good promotion, and in the summer it is more comfortable to carry out repair work. If we are talking about the quality of installation, then a good specialist no matter when to install. Although, as already noted, it is not recommended to carry out work in severe frosts.
That's probably all.

Modern windows are installed not only to replace old wooden ones; they are often preferred in the construction of new housing. What to do if the process of installing a window unit falls in the winter? Is it possible to install plastic windows in winter or will this process have to be postponed until spring?
When to install windows
Of course, it is best to do a leisurely replacement or installation in the warm season under normal weather conditions and positive temperatures. But, if the construction of a new house has been delayed, then it is also possible to install plastic windows in winter. The same applies to replacing old windows with new ones. There are some positive aspects to this season, but you need to take into account some nuances. So is it possible to install plastic windows in winter?
Benefits of winter installation
Windows in our country are a seasonal product. Most consumers try to have time to carry out installation in the spring and summer, when it is more convenient. Most often, window installation companies work under increased load during this period, so owners have to wait longer for orders to be completed.
In winter, the demand for installation and construction work drops sharply
Installing windows in winter, on the contrary, gives an advantage in the quality of order fulfillment. Most construction work, including window installation, is less in demand during the cold season. At this time, you can find interesting offers for the manufacture and installation of window systems: promotions, discounts and others. In addition, the installers will not rush, since the schedule is not so tight, which will affect the quality of the installation. These are the main advantages with which you should not be afraid to install windows in winter.
Nuances of the cold season
It is important to consider at what temperature the installation is carried out. It is prohibited to install plastic windows in winter at temperatures below -20 degrees. In this case, the construction foam, which is used as a sealant, will contain a large number of ice crystals, and the quality of such an installation will be much lower. And after a while, there will be such consequences as freezing and mold.
Also, if there is too much frost (-15 and below), the seals of opening windows become less elastic, which can lead to poor adjustment of the sashes.
The sealant for PVC windows loses its quality during installation work at temperatures below 15 degrees
If you plan to install plastic windows in a new building in winter, then at acceptable air temperatures all work can be carried out without problems.
Another thing is the replacement in residential premises. It is worth considering that installation time is 30-40 minutes for each double-glazed window, and the rooms will cool down. To do this, unlike in the summer, you need to dismantle and replace double-glazed windows in stages.
In winter, after the double-glazed windows are delivered, they need to be kept in the house at room temperature for 24 hours so that all the elements warm up. This is done in order to avoid thermal deformations..
Another option for winter installation is to carry out the so-called warm installation of window systems.
Winter installation technology
Installation of window units in winter is complicated by low temperatures and high humidity. It is necessary to somehow neutralize these negative conditions. To do this, installers can use two methods for winter installation of double-glazed windows.
The simplest winter installation
As mentioned above, in winter some nuances must be observed in accordance with the time of year.
In the cold season, frost-resistant polyurethane foam must be used to seal joints.
- Firstly, for sealing you need to use polyurethane foam with frost-resistant components in the composition.
- Secondly, in the cold season, a “heat” gun is used when foaming joints. It is used to warm up the layer of applied foam on the street side. And only then do they start filling the gaps from the inside with foam. This is done to ensure that all voids are properly filled with sealant (foam).
- Thirdly, this is a step-by-step installation. That is, having dismantled the old one, they immediately installed a new one, and so on one by one, working with each opening.
- Fourthly, the mounting tape is attached in warm conditions. If possibilities allow, then before removing the old ones.
- And fifthly, the hydro- and vapor barrier tape (PSUL) is also heated by a “heat” gun during installation.
Using a heat gun, the joint surfaces and PSUL tape are heated
This is the most basic “winter” technology for installing double-glazed windows, without which it is impossible to obtain a high-quality result.
Warm installation
The use of this technology will increase the cost of installing windows, but its use can smooth out the conditions of the winter season.
Warm installation diagram
What does the technology of warm installation of plastic windows provide?
- Warm installation of windows is a mandatory external sealing of the opening. To protect the installation site, a protective screen is attached to the opening on the street side. A heat shield for installing windows holds back the heated air in the room and prevents the installed double-glazed windows from freezing. In addition, such protection will not allow excess moisture to enter.
- For compaction, as with conventional winter installations, frost-resistant polyurethane foam is used.
- Compliance with internal sealing of the joints between the frame and the opening is mandatory. Inside there is silicone (a sealant that prevents moisture from entering). The middle layer will be polyurethane foam, which acts as a sealant and insulates the joint. From the outside, all gaps are covered with waterproof tape.
Installation of windows in winter involves a work algorithm similar to the usual one for installation in the warm season:
- The opening closes;
- dismantling old frames;
- preparation of the opening surface;
- installation work;
- finishing of slopes.
The protective screen ensures reliable and high-quality installation of PVC windows in winter
The use of warm installation technology is more preferable in winter. A protective screen in combination with materials will ensure better installation without additional risks (destruction of the seal, the appearance of mold and mildew) in any type of building (brick, panel or block house). In addition, the use of triple protection during warm installation will increase the tightness, which will reduce heating costs.
Additional work
A prerequisite for high-quality installation both in winter and summer will be the finishing of the slopes of the window opening following installation.
Why is this additional work needed? The main function of finishing slopes is to protect the gaps between the window and the opening from temperature changes and moisture. Foam is an excellent sealant and insulator, but it is very sensitive to ultraviolet rays and humidity. If you do not close the gaps, in a month the sealing layer will lose its properties, and by spring it will begin to collapse.
It is better to finish the slopes of a window opening with insulation
After installation work comes finishing work. It is best to make the slopes warm, that is, with an additional layer of insulation (foam plastic, mineral wool). In the schematic drawing you can see one of the options for insulating the internal opening. It's not a very big cost. But in this way the thermal insulation of the window will be improved.
How good is the installation?
How to understand that the windows were installed without violations of technology?
- The glass unit does not fog up and does not freeze.
- There are no drafts from under the frame or sash. When installing windows, they are adjusted and set to seasonal settings. You can check for a draft by holding a lit match or lighter to the window. If the light does not fluctuate or go out, then the sealing is correct.
- The sash opens easily without the use of significant effort, the same applies to switching to ventilation mode.
- When opening or pressing the frame there is no play in the entire system.
- There should be no gaps between the profile and the window opening.
- All joints with sills and window sills are carefully sealed with silicone.
The installer is obliged to check the quality of work and provide warranty service for double-glazed windows.
Also, during operation over a significant period of time (several seasons), the frame should not sag or become loose in the opening. And all the fittings work correctly, without jamming or failure. If there are violations listed in the list, then you need to contact the installer company. Typically, all manufacturers and installers provide a service guarantee and such defects are eliminated free of charge.
The answer to the question whether it is possible to install plastic windows in winter is yes, but taking into account some nuances. One of them is compliance temperature regime. Installation of PVC windows in winter is a more technologically demanding process, but it is possible, just as in summer. In addition, correctly installed plastic double glazed windows will significantly reduce heating costs.
Window installation in winter: debunking myths
| Article rating: |
Our specialists are often asked the question: “When is it better to replace windows, in winter or summer?” We answer: most often this question directly depends on when the repair or construction work is planned. They are often scheduled from March to November.
But there are also benefits to ordering windows in winter. To make it easier for you to decide when to replace your windows, I will give you the advantages and disadvantages of ordering and installing plastic windows in the warm and cold seasons.
Replacing windows in summer
Let's say you started a renovation. Replacing windows is one of its first stages, and all further work (for example, finishing slopes and walls) is best done in the warm season. In summer, you can safely open the windows and dry the room faster. Therefore, most residents of the Russian Federation strive to replace windows before the onset of cold weather.
That is why summer is a real boom for those who want to change the windows in their apartment. We accept most orders from August to October, and due to high production load, the timing may change.
Window replacement in winter
Oddly enough, the benefits of replacing PVC windows in winter are much greater than in summer.
- In cold weather, all the shortcomings of the room are immediately visible: blowing, freezing and other shortcomings of the walls and structures. This eliminates most of these shortcomings when replacing windows in winter.
- The disadvantage of replacing windows in the summer comes with the advantage of installing them in the winter: you can be sure that your order will be given more time compared to summer and autumn orders.
- Another nice bonus: in winter, many companies (including Kaleva) often hold holiday promotions and offer discounts. Therefore, in December-January, you can change the windows in your apartment with additional benefits.
There is perhaps only one drawback to replacing windows in winter. It is difficult to install windows in frost below -25°C. Therefore, when negative temperatures you have to use special polyurethane foam.
Another drawback rather falls into the category of myths. We are talking about cooling the room at the time of installation. It’s worth dwelling on it in a little more detail.
During the process of replacing a window, the opening remains open for no more than 40 minutes, so the temperature in the room will be restored in a maximum of a couple of hours. Often the temperature in the room is restored before all installation and finishing work is completed. So there is no need to be afraid of freezing while replacing a window.
When is the best time to replace windows?
It's up to you to decide when it's best to replace windows, summer and winter. Personally, I recommend replacing the windows in your apartment in winter. Then you won’t have to wait for the cold weather to come to understand whether the windows were installed well.
If you decide to change windows in winter, you should think about thermal insulation. The best option- which protects the house from the cold twice as effectively as a conventional double-glazed window.
I also recommend visiting our blog, where we publish useful articles about plastic windows every week.
