Many people do not represent a complete Vacation home without a cozy bath. If you haven’t got it yet, you should learn how to choose a log cabin for a bath so as not to lose a lot of money and time.
The frame can consist of timber processed in any of the ways or from beams connected in horizontal rows. It is generally accepted that only a log with a natural shape can be considered the right log cabin for a bath. In any case, doors, windows, ceilings, floors and stairs cannot be attributed to the log cabin of a wooden bath.
What is a log cabin?
A log cabin is a construction of crowns of logs stacked one on top of the other and fixed at the corners into grooves. Each log is adjusted to each other to get an even structure. Baths made of wood are very popular, many people love the unique aroma of wood when heated. Tannins are useful for the body.
The walls of a log bath warm up faster, they “breathe” and absorb moisture well. The joints of chopped log crowns can be insulated with jute tape, linen tow, felt or moss.

It is necessary to install a shallow strip foundation. There is an option and screw piles. To protect the log from getting wet, foundation ventilation is required. To do this, the vents are placed on all sides, and in the cold season they are closed. Do not skimp on roof overhangs. The higher the structure, the longer the overhangs are needed.
The distance between the building and other buildings is specified in the regulations. Compliance is checked government bodies. There are distance standards that apply only to baths, regardless of their materials. The log cabin of a log bath must be treated with a flame retardant and an antiseptic. Every time after using the bath, it must be ventilated.
Dimensions, diameters and cutting features
For even masonry, it is better to use not cone-shaped, but cylindrical shape logs. There are three types of stem processing:
- cylindering,
- Planing,
- Scraping.
The most even log is obtained by rounding. This method is also the most economical. It is important that during processing the wood is dried according to certain rules.
With a planed version, you need to follow the rule when laying logs: for each running meter a change in diameter of 1 centimeter is allowed (tapering). In the variant of scraping, all the flaws remain. There is no elimination of the curvature of the trunk. It is worth preferring only the first two processing options when choosing logs for a bath.
The design is directly affected by the uniformity of the logs. Linear dimensions in all cases depend on the overall design and climatic conditions. For summer bath thin logs are suitable, for all-weather - no.
If the building is to be used all year round, you should choose the diameters of the logs in the range of 22-28 centimeters. In cold climates, log diameters up to 36 centimeters are recommended.
Eat a large number of log cutting methods. Most popular:
- Bowl,
- Paw,
- Norwegian and Canadian cabins,
- With a fat tail groove,
- In the gun carriage
- Comb in the groove.

The choice of wood species
Answering the question: how to choose a log cabin for a bath, it should be noted that the log cabin is made of coniferous or hardwood.
conifers
Baths are made from logs of 1 and 2 grades, these can be:
- fir,
- spruce,
- Pine logs.
Their average thickness is from 14 to 24 centimeters, and the length is from 3 to 6.5 meters. It is important to know that log cabins are not made from cedar, since this type of wood releases harmful substances when heated.
Using pine and spruce, often the lower crowns are made from harder larch. It also goes under the rafters and the floor.
Spruce perfectly removes excess moisture, and pine passes air better. There is no difference in durability. A log house made of larch will cost more because it requires a lot of effort during processing. At the same time, the walls will be heavier and a little colder. The level of fire resistance of larch is higher than that of pine and spruce. The core of the larch trunk is moisture resistant and durable.
hardwood
Logs of 2 grades are suitable for a log house made of hardwood. Their thickness can vary from 12 to 24 centimeters, and the length from 4 to 6.5 meters. Design can get complicated internal partitions. The bath can be made from trunks of birch, linden, maple, poplar, aspen, beech, hornbeam.
On logs for the floor and the mortgage crown, you can take oak. Often, aspen is taken for a log house, it is resistant to moisture, resistant to pests and fires, and has a low cost. After polishing, the aspen looks great, the steam in the aspen bath is softer and more pleasant. But a bath made of such wood does not pass moisture well, the room must be regularly ventilated.
Linden is similar to aspen in terms of softness and its many irregularities. But it should be noted the tendency of linden to rot. You can make the top crowns or only the shelves fake. They won't get very hot. Birch is harder than linden and aspen, it is less prone to decay. Birch warms up better than linden.
How to choose logs for a log house correctly?
It is worth knowing that in winter time the trees "sleep" and there is no sap flow in them. wood from winter trees is durable and dry. In the summer, the trees are filled with sap, so the logs often crack when they dry out. Each crack opens the way for rot, moisture and insects.
Log sellers are well aware of these nuances. When people buy a log cabin in the summer, the sellers try to prove that it is from "winter" trees. More often than not, this is not the case. Forest storage is too expensive. If we are really talking about a “winter” forest, then logs can be stored in the open air, which destroys all the advantages of such wood. The conclusion is simple: choose good logs you can, but you need to do it in the winter. Better time for the purchase of a log house: from the end of October to March.
The quality of the log house is also affected by the place where the trees grow. A strong and dense product is obtained from trees grown on high ground and in sandy soil. If the trees grew in wetlands or lowlands, then the wood will be of lower quality. It is loose and "watery".
Often log cabins are sold in sets. This includes windows, ceilings, doors and other structures. On the one hand, this is convenient, because everything is combined with each other. But on the other hand, the kits may be too overpriced.
It is worth noting that it is better to purchase a log house directly from the manufacturer. It is always better to avoid intermediaries. Unfortunately, there are too many of them on the market. Using the services of intermediaries, you overpay a lot. The cost of the log house includes the seller's salary, advertising costs, etc.
It is more profitable to buy a log house without additional goods. Often low-quality lumber is sold complete with a log house, and from another wood. When ordering a log house, you should ask the seller what is included in the basic kit.
Log house insulation
Usually log cabins are insulated with moss. This method was used several centuries ago. Materials such as tow and jute are also popular. They do not deform over time and are realized in the form of convenient tapes. They are easy to assemble during assembly. Tape insulation is laid between a log or timber. All this is then fixed with a stapler. If this procedure is done even when assembling the bath, then it will not need to be caulked further.
log house caulk (log house insulation)
Wood has a low thermal conductivity. Heated air is stored in the bath for a long time even in winter. Often the building is not insulated at all, but simply heated for a long time. It is more expensive in terms of operation, but bath experts say that this is the only way to create the famous atmosphere of a Russian bath.
If you use pine logs that have not been pre-treated, then often resin can appear when heated, which often causes burns. This should be taken into account when inner lining premises.
When choosing logs for a bath, pay attention to such nuances:
- There should be no black or blue spots on the cut,
- The core should not occupy ¾ of the diameter of the log. It should have an even color
- There should not be a lot of resin pockets and branches on the blanks,

In the minds of many novice developers, the term " wooden house"- a synonym for high-quality and environmentally friendly building. After all, our grandfathers built it that way. Moreover, thinking about building a house made of wood, a country resident is often mistaken, believing that building such a cottage will be much cheaper than a stone house. Another point that many do not pay attention to is correct operation freshly placed log house. And this directly affects the characteristics of the house and the further costs associated with maintaining it in good condition. Therefore, in this article we will cover:
- About what nuances wooden houses a beginner builder needs to know.
- Is it possible to overwinter in a new log house.
- How to properly operate a freshly delivered log house.
Features of a wooden frame
When thinking about the choice of building material for the construction country house, then how many people - so many opinions. Wooden house can be built from timber natural humidity, dry profiled timber, glued laminated timber, rounded or debarked logs.
Each material has its fans and opponents. Without getting into, let's say that most of talk about the shortcomings of wooden houses is associated with a banal violation of the technology of their construction. The builder chooses cheaper material, the workers assemble the log house according to the principle “it will do, we always do it”. The result is a wooden house, as the user of the portal with the nickname aptly put it. Smivan85, which, after assembly, must be finalized with a file.
Smivan85 FORUMHOUSE User
For a long time I thought about what to build a house from. He considered both frame houses and adobe houses. As a result, we settled on a log cabin measuring 7x9 m. To be honest, I didn’t really control the work of the brigade, and the foreman, who, as I thought, should be responsible for everything, turned out to be an ordinary agent. As a result, I was given a log house with many jambs. The most interesting thing is that the neighbors, looking at my house, thought that it should be so, because now all the builders are hacking, and this is not the worst option.
In fact, the log house has a curved geometry (parallelogram) and poorly made corners. No nagels either.
dimaelektro Member of FORUMHOUSE
When building a log house, you need to use wooden, not metal (they rust, and the timber hangs when shrinking) dowels, for example, made from a rake handle with a diameter of 2.5 cm. Dowels are driven into pre-drilled and strictly vertical holes in a log or timber. The beam must be passed with a dowel through three crowns.
Nagel does not allow one beam or log to move relative to another in vertical plane, and also prevents the beam or log from twisting around its own axis when the wood dries.
Also in the house Smivan85 there are no beams under the floor joists, and they just hang in the air with an interval of 1 m and a span of 6700 mm.
There are practically no overhangs at the roof.
The user has already spent more than 100 thousand rubles to fix the jambs of the newly built log house. and there is still a lot of work to be done.
Important: you can not let the construction of the house take its course. All processes must be controlled, and relying on the foreman is also not worth it, and you must independently understand all the nuances of construction.
If you neglect this rule, then instead of preparing fresh wooden frame to grinding and treatment with antiseptics and paintwork materials, you will have to spend energy and money on finalizing a semi-finished house.
Smivan85
Although I like my house, I concluded for myself that such a structure is not the best option for a young family. Too much manual labor and a lot of time spent on correcting deficiencies. But the main thing is not to stand still, but to move forward, and then everything will work out.

In my opinion, the main problems of wooden houses are the low quality of felling and unprofessionalism during assembly. In addition, there are some peculiarities of building a roof, installing casing for installing windows and doors, caulking, painting, and maintenance. A wooden house does not forgive mistakes, and all the shortcomings will appear, if not immediately, then in the course of several years of operation. And most importantly, building a high-quality and comfortable wooden house is a very expensive pleasure.
Put good log house only experts in their field can, and not covens, and such masters highly value their work.
Rule One: so that a freshly delivered log house does not become a continuous headache, before its construction, it is necessary to study profile topics and articles on our portal. Wooden housing construction has a lot of features, primarily related to the fact that a wooden frame is a “living” structure subject to shrinkage (evaporation excess moisture) and shrinkage. For example, depending on the humidity and type of wood, as well as the assembly technology, a log house can shrink by 6-12%. For comparison, it shrinks by 1-2%. Those. this value must be laid down in the project in advance, so that later it does not turn out that the ceiling as a result is less than originally planned.
Usually, 1 year is allotted for shrinkage of a new log house under a temporary roof. During this period of time, you should not practice fine finish Houses.
Much also depends on the moisture content of the wood used. The moisture content of a dry chamber-drying beam according to GOST 8242-88 should be about 14-16% and not exceed 18-20%. But a bar, even well dried in special cells, where the temperature-humidity regime is maintained, in any case, it will gain equilibrium humidity. Those. take moisture from environment, which, depending on the season, can vary from 14 to 22%.
Ordinary timber can also be dried natural method(in air) to an equilibrium humidity of 18-20%. This process is uncontrolled, takes more time, and such lumber, in case of violation of the natural drying regime, more susceptible to warping, cracking and mold damage.
From here: the heavier the wood e.g. barked log large diameter, and not a bar 15x15 cm, the more time it takes to dry out in a new house.
Is it possible to immediately start living in a newly built log house
Above, we have only indicated common features wooden houses, which are directly dependent on the material chosen for construction. After all, wood is a very capricious material, whose linear dimensions (log diameter, beam cross section) are constantly changing depending on the temperature and humidity of the environment. You also need to come to terms with the fact that in a wooden house the appearance of cracks in a log or in a bar is inevitable. The house must be caulked, and at least twice - the first time after the installation of the log house, the second time after one and a half to two years, when the log house almost completely sits down.
Now consider the following situation - a house is being built as a solution to the housing problem. The goal is to move into a cottage, even if not fully finished, so as not to pay for a rental apartment. Is it justified from this point of view to erect wooden house?

We want to build a log house to solve the problem of housing and not give money for rent. I've been thinking about whether it is possible to spend the winter in a new log house with relative comfort. We plan to heat the house with electric and gas convectors.
The answer to this question depends on what is considered relatively comfortable living. The fact is that a fresh log house (already matured) must be heated very carefully, slowly raising the temperature to + 10 ° С, then smoothly to + 15 ° С and further to comfortable temperature. If you immediately raise the temperature strongly in winter, then the moisture content of the wood will increase. Fresh log cabin (“wet” wood) can no longer be sanded, antiseptic or painted, which means that the walls will remain unprotected. The wood may start to rot. The logs will begin to twist, and large cracks will go along them, large cracks will appear, from which cold air will siphon.
And this is not the whole list of problems. If you heat the house to a temperature of less than + 10 ° C, then you can generally forget about a comfortable life in a log house in winter.

To move in right away, you need to build a wooden house from glued beams. It can be finished under the "rusk". Looks beautiful and unusual.
Hut FORUMHOUSE User
I was forced to spend the winter in a log house. The house was heated by a Russian stove and a potbelly stove. The house was cut down in February and stood assembled under the roof during the summer. With the onset of frost, active drying of the logs began, and they began to burst along the plane. The walls from the inside are flat, planed, longitudinal gaps went along them. The log house was assembled on tow, and the corners immediately began to blow. I had to shut them up. The next autumn, before the second wintering, I made the first caulk. I do not pay attention to cracks, because. it is a natural "decor". The log house did not become moldy and did not rot.
The uniform drying of the log house is a guarantee of the quality of the future wooden house. You can not rush and disrupt natural processes.
Second rule: fresh log house under temporary roof, without installed windows and doors, be sure to stand for about 1 year and gradually release moisture.
If you need to call in quickly, but there is not enough money, then better near with a freshly built log house, put an insulated change house, which can then be sold, or collect a small frame house like a makeshift.
Fresh log care
And at the end of the article, a few tips from users of the portal for the operation of a freshly delivered log house.

I plan to first coat the newly installed log house with a colorless wood preservative and leave it like that. While the log is damp, it is difficult to grind. Next year, the log house can already be properly sanded and painted.
With the development of market progress building materials has increased and the assortment has become so rich, it can be difficult to make a choice on your own. When choosing the type of log house for a bath, there are always a lot of questions: Which log house is better for a bath? From what to build a bath? How to save on one or another type of material? What is more environmentally friendly and better suited for the construction of a log house. Users of numerous forums argue about which log house is better for a bath. We tried to analyze this information and combine it in one article.
Log house made of rounded logs of chamber drying according to individual project
Turnkey log cabin on a columnar foundation
A log house for a Russian bath is usually made from chopped timber, glued or profiled logs. There are options to put a bathhouse made of bricks or blocks, but this one needs to be additionally insulated. The log house of the bath is placed on the finished foundation. It is better if before this the foundation was allowed to settle for up to 1 year.
You need to choose from what to put a log cabin of a bath, starting from the quality characteristics, the pros and cons of the material and your own wallet. Read more about the pros and cons various baths can be seen in the table:
| Qualitative characteristics | Type of material for the log cabin | |||
| Timber (profiled, edged, glued) | chopped log | Brick | Blocks | |
| Environmental friendliness | Eco-friendly material except glued | Eco-friendly | Eco-friendly, except decorative with various additives | Eco-friendly |
| Fast installation | Quick assembly | Heavy logs cannot be installed alone, additional equipment is needed. Labor-intensive cutting of corner joints and selection of logs by size, which complicates assembly | Quick assembly | Quick assembly |
| Additional insulation | Profiled and glued do not need, edged timber needs additional insulation and caulking | Caulk and insulation. | Full wall insulation. | Additional insulation needed |
| Finishing | Glued and planed profiled is not needed, edged and not planed is needed inside and out. | .To give an aesthetic appearance, finishing is needed, but you can do without it. | Facade decoration is not needed, but you will have to do it inside | Requires interior and exterior finishing |
| Foundation type | Lightweight | Lightweight foundation (columnar, strip) | The strip foundation requires a lot of time and money. | Same as brick |
If we compare all the pros and cons, then a bathhouse made of rounded or profiled timber is the most profitable. They do not need additional finishing and insulation is easy to perform. Glued laminated timber is not entirely environmentally friendly, and can crack from high temperatures. Bricks and blocks are easy to install, but they need to be additionally insulated and finished.
When choosing a log cabin for a bath, you should pay attention to the degree of drying of the material. Log cabins made of glued and chamber-dried timber will shrink less, and you can use the building immediately after its assembly. In any case, it is better to give preference to natural larch, linden or aspen wood. Choosing round timber or timber, there will be problems with the connection of the material in the corners and T-shaped.
Cutting connections
Stack logs in corner connections can be in a bowl or in a paw. It can be connected to the bowl with and without a prisec.
Connecting logs into a bowl
The connection scheme in the oblo (bowl) is complex with a slit and a simple variant Connection into a bowl can be seen in the construction of old baths. A semicircle is cut out in the log, which is put on the bottom. The joints are insulated with jute or moss. The connection in the bowl is also called "in oblo". The design is well tolerated by low temperatures and strong winds. But such a cutting reduces the area, so ¼ is subtracted from a log 2 m long. Overspending of material when connecting to a bowl of 0.5 m from each link. This is one of the most common methods for joining bath logs. The structure assembled in this way is solid.
Connection in a bowl with a prisek
This is also a connection to the bowl, but complicated by cutting lock connection. A spike is cut in the upper part of the oblo, and a groove in the lower part. The bowl rises even more tightly. The only negative is that it is difficult to make such a bowl with your own hands. The progress of work is as follows: a straight line is drawn to the depth of the bowl in the middle of the end, the width is measured from it and a semi-oval is cut out. You can simplify the work by making a stencil and work on it. Professionals perform this work with a special device - a cup cutter.
In any of the ways, the bowl can be placed from above or below. The bowl down is less susceptible to moisture and cracking.
An example of cutting into a bowl with your own hands can be seen in the video:
Cutting in the paw
Scheme of connection in a paw, using the example of a dovetail This is the most difficult method of joining logs. At the same time, part of the butt is cut down, so the corners become less resistant to freezing. But they can be additionally insulated, but the working length of the logs is not lost. The felling is divided into a paw into a simple connection into a thorn and a complex one into a root thorn.
Such a connection is cut down according to a pre-prepared template, since any defects will lead to a loose connection and the corners will be strongly blown. Laying insulation in these places will be difficult, and sealed ecowool and urethane foam are not cheap. You can see the connection in more detail in the photo.
The prepared stencil is superimposed on the end of the beam or log and the future cutting is marked with notches.
It is easier to order the cutting of bowls from specialists, the price of work is from 350 rubles. for the connection.
Methods for assembling logs into a log house
An example of cutting into a thicket with your own hands during the assembly of a log cabin You need to connect logs using one method, either in a paw or in a lock. Do not take logs by length less wall baths. Each joint is an additional loss of heat, and this is unacceptable in a bath.
Logs are collected on metal brackets, wooden dowels or with rectangular wedges. Rectangular wedges are the most time-consuming method, but one of the best in terms of strength. For this, they make wooden bars the size is 10–15 cm long, 5–7 cm wide, 3–5 cm thick. Grooves are cut in the log on both sides to fit the size. The bar is driven into the lower log with a hammer, and the upper one is put on it.
We have already talked about how to connect logs with dowels (). Iron elements for connection wooden parts are not recommended. When the logs dry, they can crack and the glands will be visible, and this is ugly.
When assembling a log house, window and door openings are half cut. It is worth leaving a couple of connecting links, they will hold the geometry of the log house under the bath during shrinkage.
How to insulate a log cabin?
Caulking log house with jute rope The log house of the bath was traditionally insulated with moss. This method is still used today. But there are materials that better hold back heat: jute, tow. They do not deform and are sold in a convenient form - in the form of a tape. It is easier to lay them down during assembly. Tape insulation is laid between a beam or a log, securing it with a stapler.
If you do this at the stage of assembling the bath, then you can not caulk it in the future. Tow and moss during shrinkage may not fill all the cracks and need extra work by caulking. Caulking is carried out around the entire perimeter of the log house, both outside and inside. For this, a hammer and a special tool are used - caulking, jute or tow pre-twisted into a bundle or ready-made. It is unacceptable to caulk the walls in turn, so the bath can warp.
Choosing the right log house is only half the solution to the problem, it is important to assemble and install the bath in accordance with all norms and recommendations. It is not difficult to put up a wooden frame with your own hands, the main thing is to do it correctly and with love. If patience is not enough, and there is no experience and ability to use the instrument, then it is better to save your nerves and entrust the work to professionals.
Significantly speed up, simplify and reduce the cost of building a house can be the purchase of a finished log house from rounded logs or timber. At the same time, it is important that it is assembled correctly and from quality material. After all, a log house is the basis of construction and, with poor quality, significantly worsens living conditions.
Therefore, before choosing a log cabin for your home, you should consider the following characteristics of logs:
- type of wood,
- felling season,
- thickness
- type of felling for laying.
When is the best time to cut down trees for felling logs?
In winter, trees are in a kind of hibernation, when all the processes occurring inside them slow down or stop. This also applies to the circulation of juice, a significant part of which goes from the trunk to the roots. Therefore, trees cut down in winter can be dried to the full depth. And logs from them keep longer White color and resistant to external influences.
A log from a forest felled in the summer is of poor quality: it quickly darkens, becomes brittle and has low biological stability. Felled trees are often stored in outdoors, being exposed to high humidity. One of the manifestations of the described shortcomings of the "summer" frame is the formation of cracks on the surface of its logs, which worsen its thermal insulation and aesthetics.
Therefore, it is advisable to choose a log house for the house and buy it in the winter (preferably closer to spring). Moreover, it must be assembled from fresh logs. Thus, with the onset of warming (storage of the log house in winter conditions excludes the biological destruction of wood), you can immediately proceed with the installation of the log house.
How does the type of wood affect the quality of the log house?
The best logs in terms of quality are obtained from small-layer wood, which is durable and resinous. It is usually found in trees growing in dry soils and on hills. If you use wood that grows in damp places (for example, in wetlands), then the log house from it will be prone to decay.
Coniferous trees are considered the best option for making logs for a log house. They are best suited for log cabins of pine or larch, since their wood is characterized by high density, which determines mechanical strength and biological resistance. Spruce is characterized by a low density, which makes it possible for the walls to pass air, effectively regulating the microclimate inside the house. The disadvantage of spruce is the presence of numerous knots in its structure.
Hardwoods should be used in exceptional cases and only for the middle crowns of the log house, since they are not resistant to temperature, humidity and biological influences. The exception is oak, since its wood is characterized by high density and hardness. This allows the use of logs from it for the manufacture of the lower ones (they get wet and serve as a support for the entire structure of the house) and the upper ones (they act as a support unit). truss system roofs) log crowns.
Influence of log thickness on log quality
The diameter of the logs is directly proportional to the strength and thermal insulation of the log house. But the thickness of its walls also directly proportionally determines the mass and cost of construction. Therefore, it is cost-effective to choose a log house for the house from a log of the minimum diameter that can provide comfortable living in given climatic conditions.
For example, if in winter the air temperature drops to -40°C, then the minimum diameter of a log log is 22 cm for larch or oak and 18 cm for spruce or pine. Width longitudinal groove in this case, it is taken equal to 14 ÷ 16 cm. For building a house, it is most advisable to use log cabins from logs with a diameter of 24 cm. A wall of them is equivalent in terms of thermal parameters brickwork 50 cm thick.
How logs are cut for laying in a log house
There are 2 main ways of felling a log house. The first is called "no residue" - the connecting elements are located at the ends of the logs. As a result, a log cabin built of them is characterized by efficiency in terms of the volume of materials used and a larger usable area. Among the disadvantages of this method, one can note the reduced thermal insulation of the corners and the worst stability of the house.
In logs cut down "with the rest", connecting element located at some distance from their ends. As a result, the structure outside corners it turns out to be cruciform, which achieves their high thermal insulation and improved rigidity of the house structure. Most often, such a scheme is implemented by cutting a log “into a bowl”, which provides (with right technology manufacturing):
- no gap in the interventional junction,
- sealing joints during shrinkage of the log house,
- prevention of relative displacement of logs,
- manufacturability of the production process.
How to choose the right log house for a log house
In order to choose the best quality log house for your home, ideally, you should fully control the process of making a log house, including:
- felled trees,
- processing trunks to the required dimensions,
- preliminary log house assembly,
- all important time intervals (drying time, shrinkage, etc.).
To do this, it is useful to visit the seller's production site and see the tools and equipment used. It also does not hurt to get acquainted with the projects he completed, which stood idle for several years, in order to evaluate them. Current state. Only in this way can you be sure that a house built from such a log house will be warm, strong and durable.
03/08/2016A house or a bathhouse made of rounded logs (to readers interested in a beam for a bathhouse) is a widespread practice, to the point that you can not know anything about the subject at all, order a construction company on a turnkey basis and get the finished result. But it is unlikely that you would read our articles if everything suited you in this version.
Yes, and we ourselves believe that a good owner will definitely consider it necessary to delve into the subject, learn more about the material- which log is better for a bath, what size, diameter, how they differ, what properties they have. This knowledge is also useful in order to understand what construction is being done from, and to control some parameters or processes. Yes, and after, too - the log house is not to say that it is capricious, but still requires care.
So let's deal with everything, and along the way, you see, and dispel some myths.
Which one is better
I would like to start with the consideration of wood. And not immediately by breed, but for now only with conventional wisdom, What the best wood will be the one that was harvested in the winter.
IMPORTANT! Antiseptics must be distinguished for internal and external works, and not to be confused with each other. It is worth processing the log after laying it, and with the part that will be inaccessible in the future, they do this - they do not impregnate the tree with an antiseptic, but a jute gasket (for example).
What breeds are suitable for felling
As already mentioned, for the most part, these will be coniferous breeds. It is them that you will most often meet on the market and in the offers of construction companies.
Of course, there are many taiga in Russia, but main reason will still strength And resistance to decay due to resins. And, of course, trunk straightness- it is higher in conifers than in deciduous ones. All this applies not only to the cheap pine and spruce mentioned above, but also to the more expensive species - larch and cedar. You can also offer fir.
From deciduous we would call oak, birch, aspen, alder And linden. But only it has sufficient strength and resistance to external influences. And he is very expensive.
Since we are talking about a bath, where heat softens the resin of conifers and causes it to flow to the surface, there are two options: either partially use hardwoods to build a steam room, or to sheathe a steam room from conifers from deciduous.
Spruce has less resin and is lighter than pine. Larch and - noble species. Larch is not afraid of water, it only makes it stronger.
BY THE WAY! As for the cedar, you should not flatter yourself - this is not at all the tree from which King Solomon built. Here you will find not Lebanese cedar, but Russian ... cedar pine. That's what we call "cedar".
Whom to choose? Focus on budget. If it allows, take a larch, if not, then it will go. Although ... I would like to advise not to trust myths too much - under adverse conditions, larch may well rot, and under favorable conditions, it can stand for decades.
And be warned that round log, into which cone-shaped trunks turn, over time can present many unpleasant surprises. Especially from the same larch. If a log is taken atmospheric drying, then it very often begins to lead over time. It can twist, bend, or just go into deep cracks.
This can be avoided only if you take trunks that have been subjected to heat treatment. It is of two types - ordinary And chamber. In the first case, uniform shrinkage is achieved, but with the preservation of the resin.
The second lasts much longer, and the output is wood with evaporated resin, which does not no shrinkage, no torsional deformation, buckling, no cracking. All this is extremely valuable, but only the price of such wood is too big.
Dimensions, diameter
Before naming the dimensions of a log for a bath, let's briefly go over what we know about the trunks. First, they tend thin out closer to the crown. Therefore, the top diameter will be smaller than the bottom diameter of the cut.
And for even laying preferably cylindrical rather than cone-shaped. Therefore, of the three types of trunk processing - rounding, planing And scraping, we get the most equal only in the first case, the minimum - in the third, and the second - something in between.
In this case, the cylindering is given cheaper everything, as it is produced on machines, and the rest is connected with manual labor. Manual labor is more expensive than machine labor. But is a rounded log ideal during operation?
There is nothing wrong with the operation itself, and it gives a form that is ideal for construction.
IMPORTANT only that the wood itself does not have defects and is properly dried. In this case, everything will be fine.
Planed the option has one nuance: after all, when laying logs in a wall, one should adhere to the Gostov rule, according to which a taper of 1 cm is allowed for each linear meter. (Let us explain: taper is a change in diameter.)
At scraped there is no need to wait for the option of complying with GOST in terms of fluency. Yes, and all the flaws remain there - changes in thickness are possible in places where branches grow, and the curvature of the trunk is also not eliminated.
It is clear that the first and second options should be preferred, but not the third.
Now about homogeneity logs. There is also a rule for this:
ATTENTION! The permissible difference in the diameters of crowns used in construction should not exceed 30 mm.
That is, it does not matter if your diameters are large or small, the main thing is that they do not differ much from each other. Otherwise strength structures will be questionable.
As for the dimensions, the linear dimensions depend on project and from climatic conditions of the area where the bath will be. It should also be taken into account seasonality its use - thinner logs will fit for a summer bath than for an all-weather one.
If the task is to do very light summer building- you need to take the material with a diameter up to 18 cm. And it is also useful in all-season baths to create partitions.
More solid summer(!) bath can be made of logs with a diameter 18-22 cm.
For all-season bath suitable diameters from 22 to 28 cm. Large numbers are applicable where we are talking about objects of a large area or climatic zones with very low temperatures, there logs can be up to 36 cm in diameter (at -45 degrees, that's it).
How many pieces do you need
There is nothing difficult in the task of calculating how many logs you need for a bath. Let's describe the solution step by step:
- We look at the plan () and write out the lengths of all the walls. If you take a smaller diameter for the partition, then count the partitions separately.
- Add up the lengths of the walls. The resulting figure is the total length of one conditional crown.
- Decide what diameter the logs will be.
- The height of the bath is included in the project. Divide the height by the diameter of one crown. The resulting figure is the number of crowns.
- We multiply the length of the conditional crown by the number of crowns. We get the total length of all logs.
- The length of one standard rounded log is 6 meters. Divide the resulting length of all logs by the length of one log. The final figure is the amount of material to be purchased.
- Gables are considered in a similar way.
Bath from large and huge logs
Baths from large and huge logs, we would refer to design projects. Because there is clearly not so much a construction need as aesthetic preference. The owner of such a bath obviously likes fabulous, epic times when heroes walked the earth 🙂 And indeed the building will inspire just such feelings, even if we are talking about a bath.
Note, our opinion is that this idea has little functional meaning and often causes critical reviews, due to the inappropriate destruction of valuable ancient trees.
It would be nice if the project was done by a professional, because it is he who will have to find the ideal ratio between the dimensions of the bath itself and the diameter of the logs. Because not grotesque proportions are sweet to the eye.
A tree from which crowns with a diameter of more than 30 cm are made must grow for three hundred years, no less. Such logs for a bath need to be selected piece, sometimes designers deliberately use barrels without rounding - this enhances the feeling of antiquity and fabulousness. However, laying them in a log house will require great skill from the builders. In most cases, the choice is between cedar And larch.
In general, this is a wonderful and expensive undertaking, which is worth implementing on a large plot with a good landscape design. Or better yet, maybe not at all.
lower crown
Of course, in one article the specifics wooden construction it is unlikely that it will be possible to somehow reveal it, but the fact that the lower log in the bathhouse differs from subsequent logs is worth mentioning.
- First, it is made by several more all other crowns in the log house.
- Secondly, it does not have a completely round shape in cross section. In order to have a complete fit to the foundation, it is cut off from below edging, whose width must not be less than 15-20 cm. The second edging is cut from the inside of the room and has similar dimensions.
Outside, the crown is desirable to protect low tide, which will not allow moisture precipitation to fall on it.
Treatment inside the bath
The log house needs protection from all sides, but from the outside it is simpler, more precisely, there are simply no restrictions that operate inside, since we are talking about a bath. The fact is that the compounds that should be used for processing are often poisonous, especially for antiseptic impregnations. And the bath is hot and humid, so the substances with which the logs are impregnated will enter the air that you breathe, which surrounds your skin.
Therefore, now we will only talk about the permissible processing of logs inside the bath. However, it will vary depending on the location. So for a dressing room or hallway there are no restrictions on the use of poisonous antiseptics. The rest room can also be processed by them.
ADVICE! Choosing an antiseptic for internal works, check with the seller or Google that we are talking about a bath.
IN washing you should use formulations that are not afraid of water, and most antiseptics are water-soluble.
IN steam room you can use bleach based on bleach - it will lighten the surface of the wood and serve. You can use the steam room only after the smell of bleach has disappeared.
In the future, you can do a simple moisture protection, because mold settles on wet wood. For moisture protection, use compositions based on oil and / or wax, or Finnish acrylic varnishes for the sauna, in which they add antiseptics acceptable for the steam room.
Seams can be filled sealant for wood, and the very surface of the logs is simply grind, to reveal a beautiful "moiré" texture. Painting is acceptable almost everywhere, but in the steam room you should use only those paints that are intended for it. In the sink, paints suitable for bathrooms will do. About the paints for the bath with us.
What to caulk
The idea of caulking a log bath suggests that not all bath owners are familiar with modern means sealing joints (or do not consider them the best). Traditional the methods, of course, are time-tested, but they are very laborious and require periodic labor-intensive renewal, since the log house is constantly slowly changing its dimensions during the first 20 years of life.
Concerning materials, then it is usually used for caulking moss, tow, jute and linen. However, below we will provide a link to the video of the master, who categorically does not advise caulking with jute, because it picks up moisture well. He considers lnovatin to be the optimal material. Moss is traditional, but not common everywhere.
Tow is of different quality. The one that is worse has inclusions of all sorts of straw. Masters also do not recommend using it, because part of it will crumble over time. Linen tow good quality- excellent material for caulking.
Lnovatin- a quilted cloth, somewhat reminiscent of jute, but differing from it in quality. It is convenient for work and is not inferior to tow in terms of heat-insulating properties.
