Wood is one of the most common building materials on earth, dating back centuries. Houses, bathhouses, churches are built from wood, luxury cottages and temporary buildings are erected. The ubiquity and availability of wood provide this material with increased attractiveness in the eyes of developers.

Our portal has already described in detail, and. We continue the series of articles that we started.

So, from our material you will learn:

How to build warm and comfortable logs.
How to calculate the required wall thickness.
What features should you pay attention to when choosing the width of the groove?
What types of felling are there?

Calculation of the thickness of the walls of the log house and the diameter of the log

Will it be warm in a wooden house if the diameter of the logs is 25, 30, 35 or more cm? This is one of the main questions that any developer who plans to build a house from debarked or rounded logs should ask himself. Agree that it is unreasonable if it later turns out that the thickness of the walls is not enough to comfortably survive the harsh winter. Insulating the house from the outside or from the inside is also not an option: all the aesthetics of the log will be lost. It remains to drown intensely log house and increase energy costs or calculate in advance the sufficient thickness of the walls in relation to the region of residence.

In one of our previous articles, we already described in detail for a stone house. At first glance, it seems that making a calculation for a log house is simple - you need to find out the required normalized thermal resistance of the walls (R) of your region of residence. To do this, we find this data on the Internet. For example, for simplified calculation(for Moscow and the Moscow region) take R = 3.0 (m²*°C)/W.

Now we need to find out the actual value of the thermal resistance of a wall made of logs of a certain diameter. After which we will be able to find out (based on calculations) whether the heat transfer resistance meets the standards. To do this you need to use the following formula:

R= d/λ, where:

d - material thickness;

λ is the thermal conductivity coefficient of the material W/(m °C).

This is where the first pitfall lies. The thermal conductivity coefficient of wood (λ) is presented in the following table:

As you can see, it contains three values. Which one should you take, and what do “normal” and “wet” conditions mean?

The thermal conductivity coefficient of a material (including insulation) largely depends on its humidity. And the operational humidity of the material depends on the climate zone and the mode of use of the room.

For example, the thermal conductivity of pine and spruce (dry) across the fibers ( thermal energy from a wooden house goes outside across a log ) is 0.09 W/(m °C). At normal conditions operation (A) and during operation in a humid zone (B), the thermal conductivity coefficient of the material increases and amounts to 0.14-0.18 W/(m °C).

If the material is waterlogged, its thermal conductivity coefficient increases and the thermal resistance of the structure decreases. That's why, for an approximate calculation, let's take next value: wall material - pine, thermal conductivity coefficient of the material (average value under normal operating conditions) - 0.15 W/(m °C).

Most often, the thermal conductivity coefficient of materials and insulation materials is indicated in a dry state, i.e. obtained from laboratory tests that differ from actual operating conditions. You need to remember this when making your own calculations.

So, we figured out the thermal conductivity coefficient of wood. All that remains is to select the thickness of the wall for which you want to make the calculation. And here lies the second pitfall. The logs are stacked on top of each other, i.e. there is a groove. Moreover, depending on the diameter of the log (D), the customer’s requirements, the width of the groove (H) changes, and therefore the actual width of this unit in relation to the thickness of the log. This relationship is shown in the following figure.

It can be seen that with the same log diameter, depending on design features junction of logs, the width of the groove may vary. Therefore, it is impossible to simply substitute the thickness of the selected log into the above formula. We need some common denominator that can be used for calculations. To solve this problem, we will use the experience of a user of our portal with the nickname zaletchik.

I want to live in a log house. There is no gas on the site, and there is no prospect of it. Region of residence - Moscow region. This means that the issue of reducing heating costs is urgent. I plan to heat the house with a boiler running on diesel fuel. These input data forced me to study the thermophysical properties of the log house.

At first zaletchik calculated thermal characteristics by calculating the average thickness of the enclosing structure. This approach was not entirely correct, because heat loss was considered directly proportional to the thickness of the wall. As a result brainstorming and communication with FORUMHOUSE users, zaletchik made a more correct calculation.

To correctly calculate the thermal conductivity of walls log house I calculated the thickness of a log house made of timber, which has the same thermal insulation properties as a log house made of logs of a certain diameter (D).

Leaving the details of the calculations, which can be found in the topic, outside the scope of the article, we will immediately move on to the obtained coefficients that we need for the calculation.

For different meaningsε (H/D ratio of groove thickness to log diameter) the corresponding values of μ (Heff*D ratio of beam thickness to log diameter, having the same heat-conducting properties). The results are summarized in a table.

For clarity, consider the following example. Let's say the diameter of the log used in the construction of the log house is 45 cm. The width of the groove is 23 cm. Hence: ε = 23/45 = 0.5. Now we find in the table the value of μ corresponding to the resulting figure. This is 0.83. Next, we find the thickness of a wall made of timber in relation to the diameter of a log that has the same heat-conducting properties: 0.83 * 45 = 37.4 cm. Convert to meters - 0.374 m.

R = d/λ, where:

d - material thickness;

λ is the thermal conductivity coefficient of the material W/(m °C). In our version, pine logs – 0.15 W/(m °C).

R = 0.374/0.15 = 2.49 (m²*°C)/W

Or, you can use this formula:

R = μD/λ, where:

μ - coefficient, taken from the table above;

D is the diameter of the log in m;

λ - thermal conductivity coefficient of wood.

R = 0.83*0.45/0.15 = 2.49 (m²*°C)/W

One of the factors that determines the thermal resistance of walls is the diameter of the log and the type of wood.

Previously, we indicated that for Moscow and the Moscow region R = 3.0 (m²*°C)/W. Based on the result obtained, for walls made of pine logs, R = 2.49 (m²*°C)/W. Those. the wall does not reach the regulated value of thermal resistance. You can increase the diameter of the log or choose another wood - cedar pine. The thermal conductivity coefficient of this material (we leave the diameter of the log and the width of the groove unchanged) is 0.095-0.10 W/(m °C).

We make a calculation.

R = 0.83*0.45/0.10 = 3.74 (m²*°C)/W

That is, the standard for actual heat transfer resistance is exceeded.

You can take a different path and use another formula to find out the required diameter of the log from the ratio: the width of the groove is half the diameter of the log.

D = Rtp*λ/0.83, where:

Rtp – regulated thermal resistance of the wall;

λ - thermal conductivity coefficient of wood;

Let's do the calculation for pine.

D = 3.0*0.15/0.83 = 0.54 m.

Using this technique and “playing” with different sizes– by changing the diameter of the log, the width of the groove, the wood – you can make an independent calculation and choose optimal thickness walls of a log house.

My great-grandfather and grandfather were specialists in log building, logging and woodworking. From them I learned about the required groove width of 1/2...2/3 of the log diameter.

Also, the thermal efficiency of a log wall is affected not only by the width of the groove, but also by the profile of the log - its cross-section: round or so-called. half-log, hewn on both sides - carriage. By cutting down the wood, we reduce the thermal resistance of the wall, because... the log in the wall works with its entire section.

Of course the results this simplified calculation approximate. Most of the heat loss in the house occurs through windows, ventilation systems, roofing and foundations. Those. warm wooden house is a balanced system where all nodes work in close cooperation and correspond to each other. There is no point in making walls from logs with a diameter of 0.4-0.5 meters and choosing a wide groove, if the house is blown through cracks, A the corners freeze.

Features of felling a log house

To choose the best option for felling a log house and thereby making it warm, you need to understand what felling options exist and how they differ from each other. First we need to define such concepts as notch and crown.

Hermes-sz

Notching is the connection of various wooden parts of a log house with each other.

With proper cutting, the loads are evenly distributed between the logs. To do this, all contacting parts must fit tightly to each other. Also, moisture should not accumulate in these places, which over time can cause the wood to rot.

Crown- this is a log house consisting of four logs laid in a horizontal plane. At the corners the crown is connected with a notch. During the construction of a house, the crowns are stacked on top of each other - a wall is formed.

It should be remembered that the number of crowns depends on the diameter of the log and the width of the groove, which affects the material consumption, and therefore the final price and thermal properties of the log house. For example, to build a wall 3 meters high from a log with a diameter of 25 cm and 40 cm, a different number of crowns will be required. When building a house from logs of larger diameter, the number of cuts, locks, and inter-crown connections is reduced. Those. places that can subsequently be blown out, which will lead to heat loss.

When choosing a log for a log house, it is necessary to maintain a balance between the diameter of the log, its cost (price for the material) and the price for working with such a log.

It is physically more difficult for craftsmen to work with large diameter logs. You may also need to use special equipment - a crane.

In addition, when choosing debarked logs as a building material, we remember such a parameter as curvature.

Convergence- the difference in the thickness of the log in the ratio of the diameter of the butt and the top. A debarked log that has not undergone machine processing, unlike a rounded log, cannot be completely flat. Its lower part (especially when long length logs) are always thicker than the top. To make the wall even, when building a log house, craftsmen alternate logs of different thicknesses when laying the crowns.

The cutting itself is usually divided into two types:

Without a trace (in the paw).
With the remainder (into the bowl).

Chopping without residue, or into a clean corner, involves maximum use of the entire length of the material.

With such cutting, a right angle is obtained, which increases usable area home and reduces log consumption. But, based on practical experience, we can say that this type of corner is susceptible to freezing. To avoid this, back in the old days, the corners of a house cut down “in the paw” were sheathed with overhead boards, or, as an option, the house was subsequently lined with bricks. This prevented freezing and blowing through the corners.

Chop with remainder- a more expensive, but also more thermally efficient option. Because the ends of the logs protrude at the corners of the house; this unit is more protected from blowing, rain and freezing.

Leaving all the diversity beyond the scope of this article various types felling, let's focus on key features three main types of log cutting. This:

Russian cutting;
Canadian cabin;
Norwegian cutting.

In our country it is traditional wooden houses built from round logs. A semicircular groove is made along the log. The corner lock is made by cutting into the “oblo” into the bowl. The name comes from the word “obly”, i.e. round. The bowl can be positioned down or up.

If the bowl is positioned downward (cutting the bowl “in the middle”), then such a connection is considered more moisture resistant, and the log is better preserved.

When choosing this type of felling, you need to take into account one nuance.

Hermes-sz

The main disadvantage of Russian felling is that the logs dry out differently along and across the grain. As a result, after shrinking, the logs do not sit tightly enough in the log house.

As the diameter of the log decreases, the shape of the connecting bowls changes. The bowls open up and turn from semicircular to oval. Gaps appear. As a result, the log house has to be caulked again. In addition, open insulation is exposed to adverse weather conditions. It becomes saturated with water, and the logs can begin to rot.

A log house made in Finnish does not have this drawback. The principle is the same as in Russian cutting, except that in this version the inter-crown groove is made of a smaller radius (oval). Thus, the upper log rests on the lower one only with its edges (undercut).

As a result, when the logs shrink, the edges of the inter-crown groove do not open, the logs sit tightly, there are no cracks, and the insulation is not exposed to wind and rain.

Norwegian cutting. It is traditionally believed that a log house in Norwegian is a log carriage, although the main difference is the type of lock.

Insufficient thickness of external walls can increase the energy consumption used to create comfortable living conditions in the house (heating in cold weather, air conditioning in hot weather) by 30% or more. Therefore, you should choose from what diameter of rounded logs it is better to build a house at the stage of its design. At the same time, it is important to make other house structures through which heat loss is possible as energy efficient as possible:

openings (windows and doors),
roof (ceiling and roofing),
foundation and floor
ventilation and chimney.

What diameter of rounded logs should I choose for building a house?

Dimensions cross section logs are determined by:

the thickness of the walls, and, accordingly, their thermal characteristics,
visual perception of the house,
the required amount (cubic capacity) of lumber (while the quadrature, determined by the surface area of the walls, remains the same).

The smaller diameter of the logs requires the use of more per unit height of the log house. The number of inter-crown joints increases proportionally, and the distance between them decreases. As a result, one gets the impression that the house is assembled as if from matches. And this leads to a feeling of fragility of its design and lack of solidity. appearance.

As the diameter of the log increases, the required volume of lumber for the log house increases (due to the thickening of the walls). Therefore more warm house It will not only be more expensive (to purchase lumber), but also heavier. This may require additional costs for the construction of reinforced foundation structures.

What diameter of log is needed for year-round use?

Only A complex approach to insulation, part of which is the decision of what diameter of rounded log to choose for living in winter, will allow you to create a truly economical and comfortable home. It should be taken into account that the effective thickness of the wall is determined by the width of the inter-crown junction. And this parameter is numerically 2 times smaller than the diameter of the logs used to assemble the log house. For example, with their diameters of 22 cm and 26 cm, the width of the joint between the crowns will be 11 cm and 13 cm, respectively.

Determining what diameter of log is needed for year-round living should be done taking into account the climatic conditions that will affect the house during the period of residence in it. Obviously, the lower the winter temperature extremes, the thicker the outer wall, providing comfortable conditions for residents in cold weather. The building standards recommend the following minimum width of the inter-crown junction for specific climatic conditions:

10÷12 cm (up to -20°C),
12÷13 cm (up to -30°C),
14÷16 cm (up to -40°C).

If you use a smaller diameter of log than the one needed for a winter house according to design calculations, but a smaller one, then this is beneficial only at the stages of purchasing lumber and construction, since this helps reduce the volume of walls, labor intensity and cost of work. At other stages there is no saving, and in some cases, on the contrary, losses arise. For example, the cost of caulking (you need to purchase materials and pay for the work) will be higher, since in proportion to the increase in the number of crown joints, their total length also increases.

And in winter period insufficient wall thickness will require constant heating associated with energy consumption. The result of such intense heating is the following: over the course of several seasons, the owner of the house completely loses everything that he managed to save by using logs with a smaller diameter. It is more advisable from the very beginning to purchase lumber with the designed dimensions (taking into account what diameter of log is preferable for permanent residence in the house) and assemble a log house from it in compliance with all technological requirements. In this case, despite the increase in financial costs at these stages, constant savings in energy costs are subsequently ensured, sooner or later exceeding the invested costs.

Insulation of inter-crown joints between rounded logs

Regardless of what diameter of the log is chosen for building a house - whether it satisfies thermal engineering calculations or is insufficient, caulking of the joints is always required after assembling the log house and again after completion of the shrinkage processes. To carry it out, natural (jute or linen) or artificial (a combination of acrylic sealant and polyethylene foam cord) materials are used. They make it possible to ensure a high degree of tightness of the joint to minimize heat loss through it (accordingly, the effective thickness of the wall increases).

Our great-grandfathers built bathhouses from logs. Modern logs are processed on a machine and acquire an attractive appearance. Baths continue to be built from simple logs, time-tested and rounded. Both options are suitable and have their advantages. But what diameter of log is needed for a bathhouse? How not to make a mistake and choose suitable material? Will the walls freeze in winter if a small section is used? We'll talk about all this in more detail below.

The log for the bathhouse is selected correct diameter so that the walls do not freeze and retain heat well.

In terms of its reliability and uniqueness, wood is perhaps the most proven material. Baths built in the 50s still stand on some personal plots and serve faithfully.

Logs for the bath are selected with the same cross-section and even shapes.

From those who are skeptical, you can hear negative feedback about the insufficient width of the crown groove (the junction of the links). Opinions that a log bathhouse needs to be additionally insulated, in addition to traditional caulking moss or flax fiber. Most of the negative reviews are precisely related to the incorrectly chosen diameter of the material and the width of the cut groove. But what cross-section is optimal for building a bathhouse? How to choose the correct groove size and log cross-section? GOSTs will help answer the question.

GOST standards on wood cross-section

You can choose the correct ratio between the width of the groove and the diameter of the material using State building codes(GOST 30974–2002). The document states that the width of the groove should be equal to half the diameter of the material. The regulated size is advisable not only as a maximum for giving the log walls maximum thermal insulation, but also in order to save material consumption. The fact is that when cutting a groove we lose part of the height of the material. By increasing the width of the groove, the cost of building material will increase, that is, more links must be used to assemble the frame. Does this make sense? If you select correct section logs, then no. The optimal ratio of groove width and material height is as follows:

width ⅔ diameter;
the height of the log is ¾ of the diameter.

It has been scientifically proven that the heat-insulating properties of a log are distributed not only across its width, but also across its length. This is why it is so important to take into account the given dimensions. Now let’s determine what diameter is optimal for building a bathhouse.

What diameter of log is needed for a bathhouse?

Before answering this question, let's decide which bath we're talking about. The rounded material has a smaller diameter, since the unprocessed cross-section is measured together with the bark. Add 1 cm to the total cross-section of the rounded material. As a standard, for the construction of a bathhouse, material with a diameter of 20 to 36 cm is used.

A sauna made of logs with a cross-section of 28 cm will be reliable and will quickly warm up even in winter.

Such a wide size range is due to factors that influence the choice of diameter for your bath:

maximum winter temperature in the region;
the bathhouse will only be used in summer time or all year round;
size of the structure;
wood kiln-dried or naturally damp.

How temperature affects the choice of wood section

Winter temperatures in Russia can reach -45 °C. Each region selects a cross-section depending on its average temperature in winter time of the year:

At temperatures below -30 °C in winter, a bathhouse is built from material with a cross-section of 26–36 cm.

Southern regions with winter temperatures down to -15 °C can use a section of 20–25 cm.

For middle zone take a section no larger than 30 cm, but not less than 22 cm.

You can deviate from the norms and use a smaller cross-section, but then the bathhouse cannot be used in winter or will have to be additionally insulated.

When choosing a log manual cutting it is necessary to add 1 cm to the given section.

What is the difference between the diameter of a log for a bathhouse at the dacha and that used all year round?

Doesn't build a bathhouse on summer cottage made of large section wood. The structure will be used only in the warm season, and its dimensions are small. So, for a 3x3 bathhouse on one floor, a cross-section of 18–20 cm is suitable. This will be enough to retain heat for a short time, and the steam room will warm up quickly. You don’t have to make a massive foundation, and you can do the work yourself. With a larger section, the weight will not allow you to cope with the work without the involvement of several assistants or special equipment.

A bathhouse at a summer cottage is assembled from a small diameter log.

For a bathhouse that is supposed to be used all year round, the diameter of the lumber is taken to be at least 24 cm. The foundation is installed with a massive strip or monolithic one. Especially if the wood is used with natural moisture.

How does the size of the bath affect the choice of log diameter?

When choosing big project baths on two floors or with an attic, you need to understand that heating the structure will be more difficult. For better thermal insulation the log is taken with a larger section from 25 cm. You can use a trick and save money by building the first floor from a section from 25 cm and an attic with a diameter from 20 cm.

A bathhouse with an attic and a porch is assembled from timber with a cross-section of at least 28 cm

For small bathhouse there is no need to take a large diameter. The structure will warm up quickly and retain heat for up to a day. A diameter of 20 cm is sufficient.

For hand-cut wood, add 1 cm to the given size.

How does wood moisture affect the choice of log diameter?

When building a wooden bathhouse, it is necessary to take into account the shrinkage of the structure. So a bathhouse made from hand-cut timber with natural humidity will shrink at least 15 cm in height. After natural drying or from a winter forest, the shrinkage will be at least 4–6 cm. These dimensions must be taken into account when building a log bathhouse from a log. When choosing a section suitable for a box height of 240 cm, subtract the shrinkage.

The shrinkage of chamber-dried rounded logs is minimal and reaches 3 cm. Therefore, you should not take too large a cross-section of wood.

The larger the cross-section of wood for building a bathhouse, the higher the price for the material and assembly work will be. But you should not save money if you are building a bathhouse on long years. Factors when choosing a diameter must be taken into account not individually, but collectively. So, when building a bathhouse from rounded wood small size in the northern region, it is better to use chamber drying. The shrinkage of the box will be minimal and you can use a diameter of 26–30 cm. If the bathhouse will be used only in summer, autumn and spring, then take a diameter of no more than 24 cm, regardless of winter temperatures. Chamber drying can be used from 18 cm.

More details about how to cut a bathhouse from a large cross-section log are described in the video:

When choosing the diameter of a log for your bathhouse, consider your capabilities. The thicker the cross-section of the log, the more difficult it is to work with it and the more expensive it will be to build a bathhouse. If you harvest the logs yourself, we recommend cutting them in winter, when the wood moisture content is no more than 10–12%. Thus, the log house will give minimal shrinkage and a smaller cross-section of materials can be used.

For the convenience of the reader, we present the average indicators from GOSTs again:

the diameter of wood for a residential log house or bathhouse used all year round is 24–36 cm;
at temperatures in winter below -30 0C, the diameter of wood for a bathhouse used all year round is at least 25 cm;
to build a small bathhouse at a summer cottage, take a material diameter of 18–24 cm.

We hope that by selecting the correct log section, our readers will receive high-quality and warm bath. Which will delight the owners and all loved ones with light steam and a pleasant atmosphere.

How to choose the diameter of a log for a bath?

A real Russian bathhouse was built from wood, which has not lost its relevance in modern times. modern conditions. High environmental friendliness, healthy indoor microclimate, excellent appearance are the main advantages similar projects. In order for the bathhouse to warm up well and retain heat for a long time, to be comfortable, functional and inexpensive, it is necessary to carefully consider the choice of building materials, especially the size and diameter of the logs.

Factors influencing the choice of log diameter for a bathhouse

The production of a log house for a bathhouse involves cutting a groove in each log. If you make it too deep, the consumption of material and the number of crowns will increase. With shallow grooves there is a risk of reducing thermal insulation characteristics. Therefore, when choosing wood and calculating cutting depth, the following criteria are taken into account:

Temperature in the region where the structure is installed in winter. Depending on the installation location, in the cold season the temperature varies from -10 to -45 degrees, so the diameter of the log can be from 180 to 360 mm. The most popular is wood with a cross-section from 200 to 250 mm.
When using the sauna only in the summer, spring and autumn, the thickness of the logs can be reduced. For heating and holding optimal temperature A thickness of 180 mm is enough.
The size of the building also affects the choice of material. The larger the planned bathhouse, if available attic floor relaxation rooms, terraces, the diameter of the material increases.
The moisture content of the building material also affects the choice. For naturally dried logs harvested in summer, shrinkage can be up to 150 mm. Bathhouses made from rounded logs will decrease in height by no more than 30 mm. The thickness of the wood is calculated accordingly.

When harvesting wood and cutting a groove, certain rules also apply. The width of the groove varies from 60 to 70% of the diameter of the building material. The lifting of each crown is carried out by 75% of the diameter, respectively, the depth of the groove should be 25%.

Requirements for wood for the construction of baths

In order to get a log house for a bathhouse best quality, winter wood is purchased with humidity levels of 10-12%. A good option will be the use of rounded material that does not shrink. When calculating the diameter, it is advisable to take into account the requirements regulatory documents. Determining the cross-section of logs at different conditions operation:

For year-round use, the thickness of the wood varies from 240 to 360 mm when installed in regions with temperate and cold climates.
The construction and operation of bathhouses with winter temperatures below -30 degrees will be possible using logs of 250 mm or more.
Installation of a small building used in the warm season is made of material with a cross-section of 180-240 mm.

The use of these standards allows you to obtain high-quality construction and don’t overpay for the material. If desired, the size of the logs can be increased, achieving an attractive appearance and design. But it is not recommended to build a bathhouse from wood whose thickness is less than the minimum allowable. To warm up interior spaces you will have to spend a lot of energy, and heat leakage will negatively affect the quality of bath procedures.

The log is reliable and somewhat unique construction material, which has excellent natural characteristics and properties. For many years, logs have been used in construction not only country houses, cottages and gazebos, but also baths and saunas. The diameter of the log house is one of the most important aspects, which must be taken into account when choosing a material.

What should the diameter of the log be?

At the time of purchase, no problems with choice of this material does not arise, because in in this case the thickness will be the same at the top and bottom of the trunk. Thanks to this, no difficulties will arise in the future during construction work. In the event that it is intended to be used solid log, then it is imperative to take into account such a parameter as camber (difference in thickness). Wood cannot be absolutely even: the butt, that is, the lower part, is in any case thicker than the top. For example, if the thickness of the butt is 42 cm, in this case the thickness of the top will be 36 cm. During the construction of the log house, in particular at the time of laying, it is necessary to alternate logs so that the wall is relatively flat.

Important! Please note that the thicker the building material, the better it will withstand the effects of cold, however, the cost of such logs will be much more expensive. It is very important to know in advance all the basic requirements when choosing a building material.

Remember that the best option would be logs that are the same along their entire length. When choosing the diameter of a log house, you need to focus on the following parameters:

Material that is less than 18 cm thick is not used for the construction of residential premises. This log is perfect for the construction of temporary summer structures, outbuildings and so on. Note that this building material is relatively inexpensive option, which can be purchased at any time at minimal prices;
Logs with a thickness of 18-22 cm are ideal for construction bath rooms, as well as structures that do not involve permanent residence. As a rule, all types of log house can be used, but the type of log house most often used is “dovetail”;
Logs 22-28 cm thick are used for the construction residential complex. The cost of this material is affordable - this option is considered the most common;
A log house whose diameter is 30-40 cm will become great solution for capital construction. The most reliable and, accordingly, expensive are log houses made of larch, oak, and cedar;
A log house with a diameter of more than 40 cm is very expensive and does not justify its use in all cases.

Features and characteristics of a bathhouse made of large diameter logs

Log houses, which have a large diameter, are popular not only because of their high thermal insulation properties. If the building material is characterized large sizes, accordingly, less of it will be required, which in turn partially compensates for the difference in cost. For example, if you select a log with a thickness of 20-30 cm for construction work, the resulting difference in the amount of material used will be about 50%.

In addition, it should be noted that since less material is used, there will be fewer log connections, as a result of which fewer places with possible blowing. Due to the fact that there will be fewer locks, this means construction works will be completed much faster. Moreover, a minimum amount of tools and substances intended for processing wood will be required, since there will be fewer joints and end parts.

All of the above features and advantages make it the most popular and sought-after solution in construction market. For direct construction of a log house, it is recommended to use winter forest, which in turn is characterized by the high strength and density of wood.

The large diameter of the log makes it possible to build a warm and durable bathhouse that will serve you for many years. Of course, this building material is quite expensive, but all the costs incurred will be justified, and the structure will become a truly reliable and effective place to spend your leisure time.
