Thermal insulation of pipes in our country is a practically necessary procedure. The fact is that in winter the air temperature drops quite low. Severe frost can simply "break" the pipe. Probably, it is not necessary to explain that such a nuisance will bring many problems.

Thermal insulation for pipes - The best way protect the pipeline from bursting. Of course, it is better to do it before any problems arise. What to do if the pipes are already frozen? Either defrost them, or replace them, and after that insulate them.

WHY IS PPU THERMAL INSULATION VERY POPULAR?

The most popular material for insulation is polyurethane foam.

Why is he in such demand? The reason for this is its characteristics.

1. Sealed. It does not allow water to pass to the pipes and thereby protects them from icing;

2. Excellent heat retention;

3. Durable. Insulation made from this material can last up to several decades;

Insulation of containers and tanks with polyurethane foam

The metal container is used not only as a container for transportation. Retail outlets, small warehouses, garages, water storage tanks - and this is by no means an exhaustive list. options applications. Such a wide scope was provided by the low price, ease of installation, the ability to move to the desired point. The only disadvantage of containers is considered to be practically zero thermal insulation of such a design, and the use of most traditional insulation leads to a significant decrease in the internal volume of the container. This problem can be solved by spraying polyurethane foam, a new generation two-component material that provides thermal insulation with a minimum thickness of insulation.

Insulation of containers with POLYURETHANE FOAM

Thermal insulation of containers with polyurethane foam is a technically simple process, but it requires the use of special expensive equipment. In this regard, the price of spraying is somewhat higher than the cost of installing plate insulation, the economic effect of the technology is based on improved performance of the material.

• Installation does not require the use of additional fasteners. PPU is applied directly to metal surface container, making it possible to abandon the traditional frame.
• The polyurethane foam insulation system does not require the use of hydro and vapor barrier, which greatly simplifies installation, increases its speed and reduces the cost of purchasing materials.
• PPU protects the metal container from moisture, thereby reducing the risk of corrosion foci, which allows to increase the life of the structure.
• We recommend installing polyurethane foam insulation from the inside, the minimum layer thickness will not reduce the usable volume of the structure, and the protection of polyurethane foam from sunlight will provide a simple painting.
• Polyurethane foam insulation compares favorably with its environmental safety, which is why its use is recommended for food outlets (unlike materials based on fiberglass and mineral wool).

Before installing the thermal insulation, the surface of the container must be cleaned of existing pockets of corrosion, it is also desirable to prime the cleaned places with special compounds. Other preliminary preparation surface is not required.
The pressurized polyurethane foam mixture penetrates into all existing cracks and recesses, thanks to this, on inner surface container, a continuous coating is formed, characterized by minimal heat loss. The spraying speed is quite high, our specialists process an object of average size in just one day, and work can be performed at any time of the year. In just a few hours, polyurethane foam reaches its design hardness and strength, and the container can be used for its intended purpose already on the day of installation of thermal insulation.

INSULATION OF TANKS WITH POLYURETHANE FOAM

Installation of insulation on tanks is difficult cylindrical shape. For fastening traditional slab or roll materials requires the construction of fairly complex frame structures. That is why the most rational is the use of PPU for the implementation of such work. In addition, it should be noted that tanks insulated with polyurethane foam can be buried in the ground without additional waterproofing treatment. The material has a low moisture absorption coefficient, so PPU will provide reliable protection from impact of ground waters and other aggressive liquids.
Processing the tank with polyurethane foam allows you to organize the storage of various liquids prone to freezing, even in harsh climatic conditions. Thermal insulation of this class is also used in the installation of fire tanks to provide water supplies for fire extinguishing needs.

Insulation of vegetable stores with polyurethane foam

A big city needs a lot of food. That is why the construction and operation of premises for the storage of grain, fruits, vegetables is a fairly profitable business. The most rational vegetable storage is considered to be a prefabricated building with polyurethane foam insulation. The design is mounted quickly, has a significant usable volume, and provides the necessary storage for various products temperature regime PPU spraying, which has good thermal characteristics, will help.

Types of vegetable stores with PPU insulation

Representatives of the agro-industrial complex appreciated all the advantages of thermal insulation based on polyurethane foam. Thanks to the appearance of such a heater, it became possible to construct reliable vegetable stores from almost any building. To date, the following types of such facilities are successfully operated in the Moscow region:

• Vegetable storage facilities based on prefabricated metal hangars and large containers.
• Converted brick and wooden buildings with double or single insulation with PPU.
• Basement and ground floors industrial buildings, which, with minimal reconstruction, perform the functions of efficient and inexpensive vegetable stores.

6 reasons to choose polyurethane foam insulation

To date, PPU is gradually replacing other existing heaters from the construction market. Experts explain the large amount of polyurethane foam used in the construction of vegetable stores for the following reasons:

1. The ability to perform insulation of buildings from various materials. Polyurethane foam adheres well to metal, wood, concrete and brick surfaces. At the same time, PPU spraying does not require expensive preparatory work and the installation of supporting frames. Due to this, the cost of building or reconstructing a vegetable store is significantly reduced.
2. The use of high-performance foam application equipment can significantly reduce the installation time of thermal insulation. A professional installer is able to process up to 350-400 m2 of vegetable storage area per shift.
3. PPU thermal insulation has minimal moisture absorption and vapor permeability, thanks to which you can create a microclimate that is optimal for storing various products, while the need for additional installation no insulating coatings.
4. Vegetable storage, which is insulated with polyurethane foam, ensures the safety of products both at negative and at high positive ambient temperatures. Separate rooms of the building can be converted into efficient freezers.
5. Insulation based on polyurethane foam has a significant durability, while providing protection from sunlight (which can be achieved by simply painting the insulation), the operational life of thermal insulation reaches 30-50 years.
6. Polyurethane foam is distinguished by absolute environmental and fire safety, which is why it is recommended for use in the construction of vegetable stores. The quality of stored products is not affected even by direct contact with PPU.

THERMAL INSULATION OF REFRIGERATION CHAMBERS WITH POLYURETHANE FOAM

Refrigeration plants (industrial cold rooms) must provide a sufficiently low air temperature, creating optimal conditions for storage and transportation of food, medicines, some types of industrial products. If the thermal insulation of a domestic refrigerator does not cause difficulties, and can be performed using almost any heater, then when installing industrial-grade equipment, it is polyurethane foam that is most often used.

Reasons for choosing PPU for the installation of refrigerating chambers

The choice of polyurethane foam as the main material used for thermal insulation of mobile refrigerators and large-capacity refrigeration units is due to its physical properties and performance characteristics.

• The low specific gravity of the PPU-based insulation makes it possible to mount refrigeration units on the basis of ordinary freight transport; such thermal insulation does not create an additional load on the car chassis.
• Excellent adhesion of polyurethane foam allows it to be applied to almost any original surface. At the same time, the resulting coating is highly resistant to vibration loads that arise as a result of the operation of the installation that ensures the circulation of the refrigerant.
• Insulation with the use of polyurethane foam can be carried out both at the factory and at the place of direct installation of the refrigeration chamber. Because of this, thermal insulation industrial installations in logistics and shopping malls performed by spraying polyurethane foam. The small dimensions of the installation allow you to work both outside and inside the industrial refrigerator.
• Two-component polyurethane foam can be applied in several layers without breaking the solidity of the coating. This allows for thermal insulation. required thickness(determined by the calculation of thermal characteristics and the required mode of operation of the refrigerator). In this case, spraying is carried out in a seamless way, which significantly reduces the heat loss of the installation.
• The minimum moisture absorption and vapor permeability of polyurethane foam allows you to create the most optimal microclimate for storing various products in the refrigerator. This significantly reduces the likelihood of condensation on the surfaces of the installation.

The possibility of applying polyurethane foam in a mechanized way and the minimum thickness of the required coating can reduce the cost of manufacturing refrigeration equipment. Due to this, the price of a refrigerating chamber with PPU thermal insulation compares favorably with others. similar devices of this class.

Advantages of a PU foam refrigerator

First of all, it should be noted that polyurethane foam is absolutely harmless to the human body, in addition, the design of the refrigerator does not imply direct contact of the material with the products placed inside the unit. The use of PPU gives more whole line operational advantages compared to other heaters.

• Thermal insulation made of polyurethane foam is not of interest to rodents, which ensures reliable safety of the structure.
• The thermal performance of the installation does not deteriorate over time. Unlike rolled mineral wool or slabs, PPU does not slip from vertical surfaces. The average life of a refrigerator insulated with polyurethane foam exceeds 50 years, while the payback period of the installation when loaded above average is from 2 to 5 years, depending on the working volume.
• To improve the energy efficiency of equipment, double spraying of polyurethane foam (external and internal) is practiced. This technique allows you to provide the necessary thermal performance with a minimum decrease in the working volume of the chamber.
• Insulation with polyurethane foam makes it possible to minimal cost convert almost any room into a refrigeration unit. At the same time, the main share of the costs will be for the purchase of a refrigeration machine (compressor), the cost of applying PPU (even taking into account the price of the material) is significantly lower.

Our company carries out thermal insulation of any refrigeration units, including handicraft production, polyurethane foam. We guarantee an affordable cost and an increase in the efficiency of refrigeration equipment after insulation work has been completed.

A feature of any warehouse is a huge space, which is often simply impossible to heat normally to a temperature comfortable for the staff. Or perhaps, but then the electricity bills will just go through the roof. Therefore, first of all, the warehouse needs to be insulated, get rid of any “cold bridges”, close up all the cracks, think over such a system for loading and unloading goods that will take the minimum time to open and close the gate.

Warehouse insulation

The insulation of a warehouse is different from the insulation of an ordinary residential building: these are both huge spaces and work at height. In addition, not all companies can afford to suspend the operation of the warehouse for some time, and, therefore, the work on the insulation of the premises should be carried out at night or right in the process of the operation of the enterprise.

Consider some types of warehouse insulation:

1. Mineral wool. This is a classic way, quite cheap and therefore popular. Mineral wool is fireproof and does not rot. Its disadvantages are the high ability to absorb moisture and the high weight of the plates, which can be dangerous for walls organized from thin galvanized steel (hangars).
2. Sprayed polyurethane foam. IN Lately This is a very popular method of insulating warehouses. Polyurethane foam is not combustible, has low thermal conductivity and high vapor barrier, it is easy and quick to apply, it forms a dense seamless coating without any “cold bridges”. Its disadvantage is the rather high cost, and the impossibility of carrying out work with a functioning warehouse.
3. Sandwich panels. Finished factory panels are very beautiful, strong enough and do not require additional processing. The disadvantage of sandwich panels is the complexity of their installation and high weight, which can create an additional load on the walls and foundation.
4. Styrofoam. Very cheap way, foam boards are easy to install even when the warehouse is running. The disadvantage is a highly flammable material.

An example of how a warehouse is insulated with polyurethane foam:

See some more examples of such insulation.

Additionally: – “narrow” moment.

Warehouse heating

After the warehouse is insulated, you can also consider the heating system. What we need to know:

1. Warehouse parameters: width, height, length.
2. Required temperature. It is very important to know in combination with the outside temperature - in order to calculate the delta for which we need to warm the warehouse.
3. Heat dissipation coefficient - how the room is insulated.

Warehouse heating systems can be divided into water, steam, air and their combinations (steam-water, water-air, etc.). Let's consider them in more detail.

1. Water heating. A complex and expensive system to install, consisting of a heating point, mains connected to it and separate risers with heating devices. The advantage of this method is uniform and low heating, normal humidity in the room.
2. Steam heating. Provides rapid heating of the room, requires a smaller area of ​​heating devices. Disadvantages - complex installation, short service life of the system.
3. Air heating. High efficiency, easy installation, low cost. Flaws - large diameter air ducts.
4. Thermal curtains. Help separate warm air inside the room from the cold outside when opening the gates or doors of the warehouse. Air curtains prevent the movement of air masses and allow you to maintain the temperature regime inside the storage.

When heating, there is usually a question of choosing a fuel. The cheapest gas, but also use diesel, gasoline, electricity. Electric heating is generally the safest option with

Antipyretics for children are prescribed by a pediatrician. But there are situations emergency care in fever, when the child needs to be given medicine immediately. Then the parents take responsibility and use antipyretic drugs. What is allowed to give to infants? How can you bring down the temperature in older children? What medicines are the safest?

For development industrial production, wholesale, logistics business always requires a decent storage area. In addition, warehouses-shops and Internet trading platforms that do not have separate areas for the sale of goods are becoming more widespread.

What is the difficulty

Of course, it is not difficult to build a small warehouse building from materials that already have heat-saving properties. But if we are talking about areas and volumes for organizing the storage of products, raw materials or goods, numbering in the hundreds and thousands of square and cubic meters, then traditional methods of construction will not be economically justified.

Hangars and warehouses of large areas are most often built according to frame technology or using prefabricated structures. An example is the well-known arched metal structures assembled from wave-shaped steel sections.

The steel of the sections does not retain heat at all in winter and does not protect the internal volume from heating in the sun in summer. There are also warehouse structures made of concrete slabs also in need of thermal insulation. What methods and materials are used to improve hangars and other large premises?

Methods for insulating structures made of metal and concrete

Among the variety of ways to preserve heat in a warehouse, several basic and acceptable in terms of efficiency deserve attention.

Method 1: Create an Inner Path

The method of insulation by building an internal contour consists in the construction of a light, insulated, non-bearing frame structure inside the hangar.

Installation can be done according to various technologies- using wooden slatted or metal profile frames with the installation of foam or plate heaters and facing then panels.

Significant disadvantages of the method are the reduction of the useful area of ​​the warehouse and the high cost of construction.

Method 2: insulation with basalt and glass wool slabs

Warming with slab, basalt or glass wool material as a method is effective in terms of heat conservation, but inconvenient to implement. In fact, this is the same option as with the internal contour, but the frame is mounted directly on the walls of the warehouse.

This additionally loads the hangar sections and may affect its stability. In addition, the fastening of rails or profiles to the steel of the walls may present a certain difficulty. Another disadvantage of this method is the moisture that inevitably accumulates in the thickness of the insulation and does not go outside.

Method 3: foam as a heater

Insulation with polyurethane foam has become popular. This material exists in two forms - in the form of plates and in the form liquid mixture, which after application foams itself. Plates are used to insulate the outer surfaces of wooden or concrete walls, and the walls inside the premises are treated with foam. Liquid polyurethane is probably the most suitable insulation for steel structures.

Construction foam has good adhesion to any surface. Its heat-conducting properties do not depend on the shape of the walls, and the degree of insulation can be adjusted by the thickness of the layer. The disadvantage can be considered the impossibility of processing when negative temperatures air and walls.

Materials: properties and comparison

Let's consider several main characteristics that are essential specifically for insulation of warehouses and hangars:

• thermal conductivity, i.e. the degree of insulation of a layer of a certain thickness;
• flammability or the ability to sustain combustion. The security of the premises from fire depends on this parameter;
• specific gravity or the load that will incur building construction from insulation.

This insulator has the following features:

• specific thermal conductivity: about 0.030 W/m*K. This figure characterizes both glass wool and basalt materials;
• combustibility: do not burn and do not support combustion. Glass wool slabs withstand temperatures up to 400°C without loss of properties, and basalt fiber slabs - up to 1000°C. The walls of the warehouse covered with basalt fiber are able to withstand open fire for a long time;
• specific gravity: depends on the density of the board and ranges from 35 kg/m3 to 180 kg/m3. To insulate a steel wall, 15 cm of a layer with a density of 100 kg/m3 is sufficient. Thus, on a plot of 1 m2, the load will be 15 kg.

Styrofoam and expanded polystyrene

Styrofoam or expanded polystyrene in a solid, slab version have the following qualities:

• thermal conductivity: for polystyrene - 0.037 kg / m3, for expanded polystyrene - 0.027 kg / m3, which is quite comparable with the characteristics of mineral wool;
• degree of flammability: polystyrene foam and expanded polystyrene can burn, however, in modern production, fire retardants are added to them, which allows us to assign a flammability class G1 to these materials and call them non-combustible. The heat resistance of foam materials is low - they do not withstand heating even up to 250-270 ° C, and when burned, they emit gases dangerous to humans;
• specific gravity: foam plastic - 100 kg/m3, expanded polystyrene - 40 kg/m3, polyurethane foam (mounting foam) - 40-80 kg/m3. 1 m2 of foam plastic with a layer of 15 cm will have a weight of 15 kg, polystyrene foam - only 6 kg, and polyurethane foam - from 6 to 12 kg.

Insulation type mounting or construction foam have the same characteristics as slab polyurethane foam materials.

Comparative analysis

An elementary comparison of the characteristics shows that the degree of insulation of all materials is almost the same, the minimum weight is polystyrene foam and polyurethane foam. Moreover, the calculation did not include the weight of the frame structure, which is necessary if mineral wool or hard foam material is used. What is the safest way to use fire protection? stone wool. However, liquid polyurethane is the easiest to install.

Another important characteristic is the cost of materials. The most expensive are stone wool insulation, the cheapest are foam boards. The choice of thermal insulation for a warehouse depends on the design features, wall material and financial capabilities.

Installation work

The technology of insulation with fibrous and board materials can be described in the following steps.

The frame is assembled from wooden slats(usually for foam) or metal profiles.

The frame is fastened to the walls either with self-tapping screws or with dowels, metal profiles can be attached to steel structures with wire and welding. The thickness of the frame elements must correspond to the thickness of the insulation sheets.

To prevent the accumulation of moisture inside the mineral wool layers, it is advisable to place a vapor barrier on both sides, and if the installation is carried out outside the walls, a windproof vapor-permeable membrane. Films should be fastened with slack so that thermal fluctuations in the dimensions of the hangar structures do not damage them.

The frame is usually placed inside the building. However, in order to preserve useful volumes, it is possible to insulate the outside, followed by cladding.

Slab laying

Plates, sheets or rolls are placed between the slats or frame profiles and fixed. Possible joints are carefully sealed with scraps of the same material or foam.

Facing

It is carried out not only for the purpose of appearance more presentable, but also to prevent damage to the insulation. Another technology is used to apply a layer of polyurethane to the walls. The liquid composition is applied by spraying from special sprayers. Work must be carried out in protective clothing, ventilation is organized in the room.

After application, the composition expands on its own for some time and fills all the bumps and cracks in the walls. Freezing time is about 1 hour. As a result, a textured surface appears, which can subsequently be painted with water-based paints.

Warming various types hangars with sprayed polyurethane foam in the agricultural complex

In this article, we will try to reasonably substantiate the thesis, stating that today one of the most effective, inexpensive and quick ways thermal insulation of large non-residential premises is insulation with sprayed polyurethane foam density PPU from 45-60kg/m3 freon based.

Probably, it will not be a revelation for anyone that a building of a huge area and height, which does not have high-quality thermal insulation, can bankrupt its owner in one winter due to astronomical heating costs. You do not need to have knowledge in the field of higher mathematics in order to calculate how much it will cost to heat volumes measured in tens of thousands of cubic meters.

If such a building is not located in a subtropical climate zone and the average winter temperature outside its walls fluctuates below zero on the thermometer scale, the only solution to the problem of maintaining the required temperature inside is high-quality thermal insulation. No one will argue with this axiomatic statement. Another issue is the choice of the type of this thermal insulation and the material on the basis of which it will be implemented. Let's make a brief analysis of the main heat-insulating materials and impartially compare their advantages and disadvantages.

The main types of heat-insulating materials for the insulation of the hangar

First of all, it should be noted that all heat-insulating materials are divided into two main groups - inorganic and organic.

Inorganic thermal insulation materials

The most common inorganic thermal insulation materials include the following:

mineral wool;

glass fiber (glass wool);

foam glass.

We will not go into the intricacies of the technology for the production of these materials, since this is of little interest to the end user. Let's take a look at their properties.

All of the above materials are characterized by fire resistance, low thermal conductivity and resistance to chemical and biological (mold, pests) influences. However, despite the above advantages, they also have a number of serious disadvantages. Mineral wool And fiberglass are highly hygroscopic, which leads to the fact that these heat-insulating materials become completely unusable after a few years, if they are not impregnated with special hydrophobizing (giving water-repellent properties) compounds, and mineral wool also requires mandatory waterproofing.

The above disadvantages are devoid of such insulation like foam glass, but it has a high rigidity, which limits its use in conditions where the surface has a complex shape.

For the most part, the above-mentioned heaters are supplied in the form of blocks, which are fixed with the help of fasteners of one type or another on the walls of the room to be insulated. This inevitably leads to the fact that the integrity of the structure is damaged, which, in turn, reduces its service life to a greater or lesser extent. It is also possible to fix these materials with glue, but this method also has its drawbacks: the glue does not hold so firmly, and as a result of temperature changes, delamination of certain sections of the insulation may occur. With both methods of fastening, due to the fact that thermal insulation coating is not monolithic, so-called cold bridges will inevitably occur, reducing the overall effectiveness of the heat-insulating layer.

You can also mention in this section such material as foam concrete, which is not just T heat-insulating material, and building material with low thermal conductivity. But it's still construction material not a heater.

Organic thermal insulation materials

The most common organic thermal insulation materials include the following:

polystyrene or Styrofoam;

polyethylene foam;

polyurethane foam.

We are all familiar with the first type of the aforementioned organic heaters from childhood: which of us did not get our beloved parents, driving a piece polystyrene on glass? This lightweight material is 90% air, and air is known to be a good thermal insulator. Insulation with expanded polystyrene has long been widely used, but this material has one significant drawback - it is very fragile.

Polyethylene foam- one of the most promising modern materials, which has almost all the advantages of polyurethane foam, which will be discussed a little lower. But it also has a significant drawback - like any polyethylene, it is not heat resistant.

Now let's move on to considering the properties of polyurethane foam - a material that combines everything positive traits the aforementioned heat insulators and practically not having their shortcomings.

One of the main advantages of polyurethane foam is the possibility of spraying onto a surface of any size and shape, which results in a uniform layer of heat insulator without any joints or gaps. The result is a complete absence of cold bridges.

Due to the fact that polyurethane foam has exceptionally high adhesion to surfaces of almost any type, the possibility of delamination of the heat-insulating layer is completely excluded. In addition, spraying technology significantly reduces the time required for thermal insulation of various buildings.

polyurethane foam very effective and light: a ten-centimeter layer of this substance is equivalent in its heat-insulating properties brickwork two and a half meters thick. The lightness of the material under consideration is due to the fact that it is 85% - 97% (depending on density) consists of air or gases.

Polyurethane foam is heat-resistant and frost-resistant, which allows it to be used in all climatic zones. It does not require any additional waterproofing, and even more than that - its rigid variety itself can serve as an excellent waterproofing agent and is widely used in construction as such.

Another advantage of this material is the excellent soundproofing properties.

In view of the foregoing, we can safely say that it is polyurethane foam that is most suitable for insulating metal structures such as hangars. The lightness of polyurethane foam allows you not to overload the structure of a metal sheet with a thickness of just over 1 mm; heat resistance will be needed during the hot summer months when metal gets very hot high temperatures; frost resistance allows you not to fear for the strength of the thermal insulation layer even in severe frosts, and the absence of cracks ensures that not a single drop of precious heat seeps out. If we add to this the speed with which insulation is made with polyurethane foam, it becomes clear that prefabricated hangars and this heater is simply made for each other.

PPU warehouse insulation is beneficial

Many shopping malls manufacturing companies, shops and firms require their own storage facilities. The key task of such structures is to ensure proper storage conditions for various cargoes. The warehouse must comply with the established storage standards in order to avoid damage to the cargo and change its parameters. Maintaining a certain temperature and humidity regime in a warehouse is a priority for every business owner. An uninsulated warehouse leads to many troubles. There is a problem of maintaining the desired temperature, as a result of which the conditions for storing goods are violated, the work of equipment and people is difficult. Condensation is formed, leading to the appearance of rust on equipment, rotting of floors and dampness of stored products. As a result, electricity costs rise and the company's losses grow. To avoid this kind of consequences is possible only through competent.

Warehouse insulation with polyurethane foam effectively solves a number of problems. This option is rightfully considered one of the best from a technological and economic standpoint. PPU spraying has a lot of positive aspects that favorably distinguish it from other outdated alternatives: foam, fiberglass, basalt wool slabs.

Warehouse before and after application of PPU

Warehouse insulation is a rather complicated and costly process. The complexity of thermal insulation of warehouses is due to their design features. Typically, such structures are based on prefabricated frame structures with an arched dome. Standard methods of thermal insulation of the premises, applicable for residential buildings, are unprofitable here. In many cases, they do not provide the desired result. Highly effective modern methods come to the rescue - insulation of the warehouse with polyurethane foam.

Warming warehouses in the indicated way provides a lot of advantages. The material is easy to apply. The composition, the components of which are liquid polyol and isocyanate, is sprayed onto the surface under great pressure. When applied, it increases in volume many times over and freezes almost instantly. Therefore, the insulation of warehouses of a large area can be done in a day by only two people. The material has the lowest coefficient of thermal conductivity in comparison with other building materials - 0.019 W / M * K.

PPU can be applied to previously unprepared surfaces made of iron, concrete, brick. A frame is not required for this, as well as the use of special fasteners. The shape of such surfaces does not matter either - the material fits perfectly into all the recesses, filling them with itself. The complex geometry of the warehouse will not be a problem for this polymer. It adheres tightly to all surface irregularities.

Insulation of a PPU warehouse is economically beneficial due to the fact that the material minimizes heat loss and energy costs. The resulting coating has no seams, gaps, joints. The polymer layer is equivalent to 500 mm thick brickwork. At the same time, for the insulation of warehouses, a coating with a thickness of 50-80 mm is quite enough. This ensures savings in usable space required for storing products, cargo, etc.

The advantages of polyurethane foam are obvious:

He is not afraid of moisture, which eliminates the need for waterproofing.

Incombustible. The material is not flammable and does not support the combustion process. Garage insulation with polyurethane foam provides fire safety designs.

Able to effectively fill all existing voids.

Provides good sound insulation.

Protects the metal structure of the garage from the appearance and spread of corrosive processes.

Thermal insulation is completely waterproof, it does not form gas condensate, the development of fungus and plaque. The low density of the material leads to a decrease in the total load on the supporting structures. The cellular structure of the material ensures proper vapor permeability of the heat insulator. This serves as a guarantee of the absence of dampness and mold, which is especially important during storage. food products in stock.

PPU does not react with water and chemicals. Excellent adhesion of the polymer provides excellent bonding of the heat insulator with any type of wall.

PPU is environmentally friendly and safe for health. It does not contain harmful impurities. It can be freely used for the insulation of food warehouses. It is resistant to burning and temperature extremes, successfully copes with both frost and heat. The combustibility class of the GZ material ensures that it is not capable of becoming a source of ignition and does not support the combustion process. The created thermal insulation can last 30-50 years without any repair.

This material organically combines excellent heat, noise, and waterproofing. PPU warehouse insulation is a great way to provide high-quality thermal insulation of this type industrial facilities at the maximum speed of work on large areas.

If you are in business, then it is not for us to tell you how important the reliability of storage facilities is. Just imagine that frost hit and all your goods suffered from it. Such situations need to be considered in advance. This will avoid losses.

Warming of warehouses will help to keep a trade dress of your production all the year round. This procedure also allows you to save money, since after thermal insulation you will be able to heat your warehouse not as intensively as before. After all, insulated walls retain heat inside the room.

What material should be chosen for thermal insulation of a warehouse?

If you decide to insulate your warehouse, then it is best to choose polyurethane foam for this purpose. It has a lot of advantages:

Ease of installation. Work on insulation using this material will take no more than 1 day. Agree that such terms are quite attractive;

Saving. In addition to the fact that your goods will always be safe, you can save on heating. Insulation of warehouses with polyurethane foam reduces energy costs by 50%. A one-time investment in thermal insulation will help you save money for years to come;

Durability. Polyurethane foam as a heater can last for several decades.

Warehouses are designed to store various materials and goods. Often, for the storage of certain groups of goods, special conditions, including a certain temperature, humidity, in general, the microclimate. To create these conditions, the premises must be isolated as much as possible from the effects of environmental conditions, that is, sealed and thermally insulated. In a cold climate, the facades of houses are not able to retain heat inside the premises by themselves. As a result, there are high heating costs, the low efficiency of which is due to the high thermal conductivity of building materials.

POLYURETHANE FOAM IS THE BEST SOLUTION FOR WAREHOUSES

To date, for the thermal insulation of rooms of any type, many modern heaters are used, which are designed to solve various problems. However, for the insulation of warehouses, polyurethane foam, or polyurethane foam, is best suited. This heat insulator has unique characteristics, so far unattainable for other materials. In particular, polyurethane foam has the lowest coefficient of thermal conductivity, which allows you to recoup investments in thermal insulation in just two seasons, and subsequently save up to 50% on energy resources for a long time.

PROPERTIES OF POLYURETHANE FOAM SO NECESSARY FOR WAREHOUSE INSULATION

The only drawback of PPU can be called exposure to ultraviolet rays. However, this problem is solved by simply painting the thermal insulation with any paint that will protect the surface.

Naturally, it is impossible to create the necessary microclimate in the warehouse only by thermal insulation of the premises. Therefore, in combination with a heater, it is necessary to take care of high-quality, well-thought-out ventilation. Such a complex will help make your warehouse an ideal place to store any goods.

To get rid of the so-called "cold bridges" in warehouses, it will be necessary not only to close up all the cracks. Given the fact that such rooms have a large area, it is necessary to insulate all the walls well. It is necessary to get rid of such a phenomenon as a leak of warm air.

What is the difficulty?

Today, during the construction of new warehouses, they are immediately used. But what if this is an old room and it is necessary to place goods in it, which winter time should be stored at positive temperature? In this case, you need to think about doing repair and finishing works using heaters. And first of all, you need to insulate the walls. But no matter what insulation is used, it will be of little use if the issue with the gate is not resolved.

The thing is that the gates of many warehouses open almost daily to carry out the process of unloading and loading products from trucks. Therefore, two questions need to be addressed at once:
- the gates must be opened for the shortest possible time;
- the process of loading and unloading goods must be minimized in time.
In most cases, hangars and warehouses have a large area. In addition, they are built using a special frame technology. In the process of their construction are used metal constructions and steel sections, which are completely incapable of retaining heat. Therefore, they must first be insulated.

Not every warehouse can suspend its activities in order to produce Finishing work wall insulation from the inside. Therefore, such work often has to be done at night. When carrying out the insulation of the walls of the warehouse, it is necessary to take into account very important nuance: many works will have to be done at a height, so additional equipment will be required in the form of a tour - a mobile tower or convenient stairs.

The main types of warehouse insulation are most often used such materials:
- mineral wool;
- sprayed polyurethane foam;
- sandwich panels;
- Styrofoam.
Each of these heaters has its own advantages as well as disadvantages. Therefore, they should be considered separately.

1. Mineral wool: is a classic way to insulate warehouses. This method of insulation is cheap. In addition, mineral wool fireproof, which is very important for such premises. But she also has drawbacks. For example, it is able to absorb moisture. In addition, it has a decent weight for a heater, which can be dangerous for thin walls from galvanized steel.

2. Sprayed polyurethane foam has been very popular lately. He is able to close up all the cracks, is not afraid of fire, has low thermal conductivity. It is very easy and quick to apply on the walls. But its disadvantage is the high cost. Yes, and the warehouse must be stopped for the duration of such insulation.

3. Sandwich panels are very beautiful and strong enough. Their advantage lies in the fact that they do not require further finishing. But from the shortcomings of such a heater, one can single out the laboriousness of the work and their decent weight. And this means that the load not only on the walls, but also on the foundation will increase significantly.

4. Styrofoam is the cheapest insulation. When the walls are insulated, the warehouse can not even be stopped. It also differs in that it is very light. But it also has disadvantages: rodents love it and it is a highly combustible material.

Therefore, how to insulate your warehouse is up to its owner. In this case, it is necessary to take into account its size and what material it is built from.

Foreword. In this article, we will consider an important issue for companies whose activities are related to the rental and operation of warehouses. In order to reduce the organization's costs for heating storage facilities and create a comfortable climate for employees to work, it is necessary to insulate the warehouse walls, roof, floors and hangar gates. It is to this question that we decided to pay attention in this material.

Insulation with foil insulation

A feature of the warehouse is a huge space with concrete floors and large gates, such warehouses are often impossible to heat up to comfortable temperature for a person. So that the warehouse owner’s electricity bills are not ruined, it is necessary to insulate the warehouse for the winter: get rid of “cold bridges” and seal up leaks of warm air.

First of all, it is necessary to think over the process of loading and unloading, which would take the minimum possible time to open the gate. It is also necessary to pay attention to the thermal insulation of the roof, concrete floors and walls from the inside in the warehouse. Let us further consider the question of the better to insulate a warehouse for the winter and describe some ways to insulate warehouses from the inside.

How to insulate a warehouse from the inside

The insulation of warehouses and hangars differs from the thermal insulation of a residential building, since it requires the processing of huge spaces, structures and work at height. In addition, it is often impossible to stop the activity of the warehouse even for a while, therefore, all repair work will have to be carried out by builders inside at night or during the work of the enterprise.

How can I insulate a warehouse from the inside for the winter:

1. Mineral wool(glass wool) - classic and enough cheap material. Mineral wool is fireproof (this is a significant plus for a warehouse where flammable substances or goods are often stored), the material is not subject to decay and decomposition. The disadvantage of basalt wool is the ability to absorb moisture and the low density of the plates - this requires the construction of a frame where the mineral wool plates will be laid, and the protection of the thermal insulation with a vapor barrier membrane from getting wet.

2. Styrofoam or foam- the cheapest insulation, the plates are easy to mount and there is no need to stop production. Extruded polystyrene foam has the best characteristics and is perfect for insulating a concrete floor in a warehouse, roofing and walls, as the material is very durable, while being lightweight and not afraid of high humidity. The foam is less durable, in addition, the insulation is highly flammable and emits harmful substances during combustion, which is unacceptable for fire safety.

3. Spray foam- a very popular way to insulate roofs and walls in industrial premises and warehouses. Sprayed polyurethane foam (PPU) is a lightweight and durable material, non-flammable and has low thermal conductivity.

PPU is quickly applied and forms a seamless coating, resistant to moisture and without "cold bridges".

The material can be applied to any surface: wood, concrete, metal. The disadvantage of this insulation is the high cost, as well as the impossibility of carrying out all the work with a working warehouse.

How to insulate a cold warehouse in winter

How to insulate a gate in a warehouse

To insulate the gate in the warehouse, you can use expanded polystyrene or foam plastic. The material is light, durable, not afraid of precipitation. You can use sheets 50 mm thick, which are inserted into a frame made of 50x50 mm wood bars. The timber is pre-treated with an antiseptic, and all remaining seams between the foam sheets are sealed with mounting foam.

When the entire gate area is insulated, moisture-resistant plywood or OSB is mounted on top. The whole technology is no different from garage door insulation. Also, the gate can be insulated with mineral or glass wool, which also fits into a frame made of wood bars. The width of the beam must correspond to the thickness of the thermal insulation layer, which can be calculated on the calculator.

Before laying the basalt wool, the entire frame and gate are covered with a moisture-proof membrane. After laying the insulation, the frame is again closed with moisture insulation, so that the mineral wool is protected from getting wet from all sides. Next, bars are attached to the frame to create a ventilation gap so that moisture evaporates from the surface of the film, and the gate is sewn up with plywood or OSB.

How to insulate a roof in a warehouse

Insulation of the hangar roof is often difficult due to the significant height of the structure and its lightness, which is why it is often impossible to use heavy structures. A simpler, but more expensive way to insulate a roof in a warehouse is to hire specialists who will quickly spray polyurethane foam on the structure. Polyurethane foam will create a continuous layer without seams and will not load the roof of the hangar.

A cheaper, but at the same time labor-intensive method is the creation and insulation of the ceiling ceiling. In many cases, this method is simply impossible to implement due to the significant loads on the light structures of the walls and roof of the hangar. If the warehouse has concrete walls and overlap, then there should be no problems. You can use any roll and slab insulation for this.

Slabs of mineral wool or expanded polystyrene should be laid in a pre-designed timber frame. The distance between the bars should be made 1-1.5 cm less than the width of the mineral wool or glass wool sheets so that the insulation fits as tightly as possible to the bars. Additionally, the thermal insulation should be fixed with a dowel - with fungi and covered with a vapor barrier to protect it from moisture.

How to insulate a concrete floor in a warehouse

Scheme of insulation of concrete floors on the ground

The concrete floor should be insulated even at the stage of the construction of the hangar. Thermal insulation is produced by the method of warming the earthen floor with foam plastic or foam plastic. Insulation plates are laid on the previously leveled soil (for this, the foundation should be poured from the inside with soil or sand). A caracas of reinforcement is knitted on top, and the floor in the hangar is poured with a thick layer of concrete.

If it is required to insulate the floor in the hangar after the completion of construction, then this work will require significant financial outlays. Since it will be necessary to re-lay the insulation and pour concrete where cars and forklifts will drive. In those rooms where there will be no significant load, it is possible to insulate the floors along the logs, using foam plastic or mineral wool as a heat insulator.

This floor insulation technology was described in detail earlier in the article “Which floor insulation is better in a wooden house” and will not amount to great work. All work on the insulation of the hangar for the winter from the inside can be done in stages, so as not to completely stop the work of the organization.

The issue of warming storage facilities is as acute as the problem of reducing heat loss in winter when open gate. Sometimes vestibules are used for these purposes, which greatly complicates the process of loading and unloading. Another popular option is the use of heat guns, which are able to quickly warm up the air in the room after it cools down with the gate open.
