Calculator for calculating timber for building a house / bathhouse

In order to select the correct amount of material during construction, we suggest using a timber cubic capacity calculator

, which allows you to calculate the total volume of available material, the volume of one unit, find out the number of pieces in 1 m3, the total weight and cost of production. The service performs calculations only for four-edge assortments with rectangular and square sections. To start the calculation, fill in all the appropriate fields of the online calculator and click the “Calculate” button.

On this page you can calculate the amount of timber needed to build a house, and get the result in cubic meters and pieces. As you understand, it is only possible to accurately calculate the amount of any material needed to build a house if there is a project. But knowing the prices for various timber, and using our calculator, you can quickly estimate many options for house configurations and get a preliminary result, with the help of which you can get an approximate idea of ​​the future costs of building a frame house from timber.

Timber is sold in cubic meters, but sometimes you can see the price per piece, and it is very useful for yourself to know how many pieces of timber you will need, for this purpose this calculator for the amount of timber for building a house gives the answer in two options simultaneously - and pcs. and m3.

Information on the purpose of the calculator

The online calculator for profiled and laminated timber is designed to calculate the quantity and volume of lumber for the construction of houses, bathhouses and other buildings. The amount of inter-crown insulation, dowels, crowns, cost and anti-corrosion impregnation is automatically calculated based on the average value. For more accurate calculations, be sure to contact specialists in your region.

When filling out the data, pay attention to the additional information with the sign ❗

To understand the advantages and disadvantages of profiled timber compared to laminated veneer lumber, you should start with the basic concepts about the production of both.

Profiled timber is made from coniferous trees. In most cases, it has standard section dimensions:

• 100x100 mm - best suited for building a bathhouse or summer country house
• 150x150 mm - suitable for a good home
• 200x200 mm - for the construction of large wooden houses or cottages

If desired, you can individually order timber of a different section. The appearance of the timber can be either with a straight front side or with a D-shaped one. A log of the required thickness is processed on planing and milling machines, after which it is ground on the required sides. The side of the beam that will be located inside the future house and may not require further finishing is usually subjected to high-quality sanding. For convenience and reliability of installation of a log house and for protection from cold and moisture, the profile most often comes with 1 or 2 tenons for a lightweight structure or a “comb” for a residential building. The finished log house must shrink for further completion of construction, usually this period is about 1 year. To reduce this period to several months, you can dry the timber in advance in special chambers.

To produce laminated veneer lumber, logs are sawn into boards, which are also called “lamellas”. The boards are cut and placed in a drying chamber, where the soft drying process produces material with a moisture content of about 10%. The boards are then planed again to the required dimensions, sorted, and then glued into timber using a hydraulic press. For gluing, special waterproof adhesive compositions are used. To make laminated timber resistant to rotting and significantly increase its strength, the boards are laid in a special way - each is laid opposite to the cross-section of the fibers of the neighboring one.

When assessing the strength of materials, it is necessary to recognize the best performance of laminated veneer lumber.

In profiled wood, during the production process, the outer, stronger part of the wood is cut off to give the desired shape. Glued laminated timber, due to the previously described method of laying boards and gluing them on a hydraulic press, is more durable. As many people know, larch is the most durable and rot-resistant, but also the most expensive among conifers. Making profiled timber from it significantly increases the cost of construction. When producing laminated veneer lumber, it is possible to lay an external larch lamella before gluing, which has a slight effect on the increase in price.

When comparing the moisture content of the material and the shrinkage time, it has already been noted that laminated veneer lumber has a moisture content of about 10% and, accordingly, a short shrinkage time, which makes it possible to reduce the construction period of a house. Profiled timber has the natural moisture content of wood, and even drying it can reduce the moisture content only to 20%, so shrinkage cannot be avoided. When comparing shrinkage periods, we must not forget the fact that solid material, due to its greater massiveness, is practically not susceptible to cracking, but on laminated veneer lumber there is a possibility of small cracks occurring.

Due to technological manufacturing features, each type of timber may have different overall dimensions. The profile usually has a length of up to 6 meters, and a cross-section of 100x100, 150x150 and 200x200 mm. Manufacturing timber of a different section size (for example, with a step every 10 mm) can increase the amount of waste, which cannot but affect the price. The length of laminated veneer lumber can reach 12 meters, and the cross-section is usually made from 80 to 280 mm.

In terms of cost, solid timber is almost 2 times cheaper due to the less complex manufacturing process.

But taking into account only the cost of the finished log house, do not forget that finishing for facades when using laminated veneer lumber may not be required, and comparing them in price is a stretch. Everything will depend on the material chosen for finishing the house, its quantity and cost.

In terms of environmental friendliness, profiled timber is not just a favorite, but rather a champion, preserving all the beneficial properties of such an excellent material as natural wood. For processing, you may only need special mixtures to protect against fire and rot, which the owner of the house can choose. In the production of laminated veneer lumber, adhesive compositions can be used, which are divided into several groups according to the degree of danger, and it is not a fact that the manufacturer did not decide to save on the cost of the glue.

In conclusion, we can say that each of the 2 types of timber considered has its undoubted advantages with a small number of disadvantages. And only the owner can decide what material to build the house from in order to continue living in it.

The following is a complete list of calculations performed with a brief description of each item. If you haven't found the answer to your question, you can ask it in the comments.

Peculiarities

The bathhouse was used not only for washing, but also as a health complex. It is especially good for treating respiratory tract problems, such as bronchitis. The steam room is good for obesity and has a positive effect on recovery processes. Accelerating sweating helps remove toxins from the body. The presence of a bath broom in a steam room is a mandatory law for a Russian person. The most common brooms are knitted from birch, linden, spruce, and oak. These trees contain resins and substances that have a beneficial effect on the body. A broom removes keratinized particles of the epidermis from steamed skin, so a person looks younger after a bath.

A contrast shower helps harden and stimulates blood flow, therefore enriching the body with oxygen. It is not for nothing that from time immemorial people have placed bathhouses on the banks of rivers and lakes.

The famous Russian custom of plunging into an ice hole after a steam bath is known all over the world. Our ancestors well understood the benefits of contrasting temperatures. That is why there was a boom in the construction of bathhouses from logs.

The peculiarity of the 6 by 4 size is that, despite a fairly spacious room, the structure is compact and does not take up much space. You can find a place for a 6x4 log house even in a small area. A building material such as timber has many advantages over others.

• Timber is an environmentally friendly material.
• It has antibacterial properties due to the presence of essential oils in the wood.
• Unlike log baths, construction from timber requires less building material, therefore, this is a considerable saving.
• The timber is less prone to delamination, which means that the appearance of cracks on the side surfaces is minimized.
• It is much easier to build from timber; even a novice carpenter can do it. Many owners lift the box from the timber with their own hands.
• The walls are smooth, neat, look good, provide a large area inside the house and quickly shrink.
• A bathhouse made of timber has less weight than a log bath - it requires a smaller foundation. It can be made as a strip or the structure can be placed on poles.
• Immediately after completion of construction, interior decoration can begin.
• Due to the presence of resins, the middle of the trunk becomes denser with age, which only increases the strength of the structure.
• The universal dimensions allow you to build an attic or a full second floor, or turn a bathhouse into a cozy guest house.

The inside of the building is usually divided into four compartments:

• steam room;
• washing;
• dressing room;
• restroom.

All interior spaces do not have mandatory dimensions. Some people like a large washroom, others can increase the steam room compartment by reducing the washing section.

You can reduce the size of the dressing room by increasing the area of ​​the rest room.

There are many options - there are no restrictions for fantasies and desires.

General information on the calculation results

1. Total timber volume

— Estimated amount of lumber in cubic meters.

2. Total wall area

— The area of ​​the outer side of the walls. Corresponds to the area of ​​the required insulation, if provided for by the project.

3. Total weight

— Weight of timber excluding insulation.

4. Number of crowns

— Number of rows of timber in one wall. Depends on the height of the walls and the size of the material used. Excluding gables.

5. Amount of roll insulation for all crowns

— Equal to the total length of all beams.

6. Diameter and number of dowels in 1.5 meter increments

— This calculation is suitable only for lightly loaded timber buildings. For critical buildings, the calculation of dowels must be carried out by specialists in your region.

7. Amount of impregnation on both sides

— The calculated amount of protective impregnation of medium grades, covering the external and internal surfaces of all walls.

8. Approximate shrinkage (4%) of profiled timber

— Approximate shrinkage of walls made of profiled timber after 1 year, with an initial humidity of 20%.

9. Load on the foundation from the walls

— Load without taking into account the weight of the roof and ceilings, with support on the entire surface of the lower crown. This parameter is necessary to select the strength characteristics of the foundation.

Types of material

Timber is divided into four main grades. The most expensive is the “Extra” grade, in which it is difficult to find defects, which justifies the high cost. Grade “A” is cheaper, but the quality is almost as good as the first. Grades “B” and “C” are considered second-class and are used for exterior decoration or for the construction of utility rooms.

To build a bathhouse, it is advisable to use “winter” tree varieties: larch, linden, oak. Some people make a steam room out of linden, since it heats up faster and does not burn the skin. The remaining rooms are decorated with foliage, since linden, although cheaper, is less protected from external influences.

Timber for a bath complex is also divided into profiled, glued and non-profiled.

1. Regular (non-profiled) timber. The low cost is due to the lack of special processing. The material does not resist the influence of the external environment well, can be susceptible to fungal diseases, and shrinks a lot. It is used less and less in the construction of baths.
2. Log houses made of profiled timber have a higher cost. Unlike the usual profiled timber, it has a rectangular cross-section with technological grooves. Thanks to this solution, there are no gaps between the beams and no caulking is required.
3. Glued laminated timber is not solid wood, but a layered material made from lamella boards. Complex technology is used for its production; the whole process consists of several stages. The boards are pre-dried and treated with antiseptic compounds and oils. In all respects, a log house made of laminated timber is superior to other types.

The most popular timber size in construction is 150x150 mm.

In harsh weather conditions, for example in the northern regions of the country, thicker timber is used: 180x180 mm, 150x200 mm, 200x200 mm.

You can use sizes 100x100 mm and 150x100 mm, especially since this reduces the cost of the material.

Calculation of construction timber in cubic meters

And so, how to calculate the amount of timber

in 1 cubic meter using the simplest method? It should be noted that the example below is not exact. To make a more accurate calculation, you need to have a project of the future house.

To calculate the amount of timber in 1 m3 you need:

• Calculate the perimeter of the building;
• Multiply the perimeter by the height;
• The product of the perimeter and height must be multiplied by the thickness of the product.

For our case, the formula will look like this: V = h*b*l = 0.15 * 0.15 *6 = 0.135 m3,

Where:

• h is the height of the beam;
• b – width;
• l – length.

Let's find out how many units of lumber are in 1 cube as follows: 1/0.135 = 7.41 pieces.

After carrying out all the above calculations, we will get the result of the number of cubes of timber required to construct the building.

To calculate timber

, which will be needed for finishing the interior walls, we use a similar method.
Let's look at a specific example of how to calculate the amount of timber
for a bathhouse 5 * 10 meters, 3 meters high.

Let us conditionally determine that during construction the size 150 * 150 mm will be used.

Example:

• (5 m – width + 10 m length) × 2 = 30 m – perimeter of the building.
• 30 perimeter × 3 height = 90 m2 – wall area.
• 90 area × 0.15 material thickness = 13.5 m3 - needed to build a box from 5x10 timber 3m high.

In this simple way, we calculated the amount of timber for the walls, which is 13.5 m3. But, you need to take into account that due to the presence of window and door openings, the amount of material used will be less than calculated.

Often craftsmen do not take this point into account; it is believed that it would be even better to add about 20% in reserve, in the end we will get: 13.5 + 20% = 16.2 m3 of timber needed for a building 5 * 10 m.

Features of timber that must be taken into account when calculating

When building a house from timber, the first step is to lay the crown, which should be slightly thicker than the main beam. The first crown is made of thicker timber; later the weight of the whole house will put pressure on it, so it is additionally recommended to treat it with machine oil or an antiseptic.

In the calculation described above, this nuance was not taken into account; it must be calculated separately.

General information

Any construction, even if it is a bathhouse measuring 3x4 meters, requires the availability of design documentation.
It is necessary not only for calculating materials and drawing up estimates, but also as instructions for performing construction work. A drawing of a bathhouse made of 3x4 timber, which will be in front of your eyes during the construction process, will allow you to avoid mistakes at all stages of the work. Therefore, you should not neglect the preparation of the project even when constructing such small buildings.

Three-dimensional design of a 3x4 bathhouse

Calculation of timber in units

After you have calculated the amount of timber in m3, you can easily find out how much timber will be needed in units (pieces). Let's look at the table of the most common sizes of timber 6 m long:

Table of the amount of timber in 1 m3 for calculating timber for a house.

In the above example, where we indicated the cubic capacity of the timber for the bathhouse, we will carry out further calculations of the materials in pieces.

In order to calculate the amount of material per house in pieces, we carry out the following calculation; for this, the amount of 13.5 m3 must be divided by the cubic volume of the timber used, in our case it is equal, based on the table, to 0.135 m3: 13.5: 0.135 = 100 pieces.

If you correctly calculate the amount of timber in pieces, then when purchasing timber you will be able to control whether all the material is shipped to you by the seller.

Nuances of designing basic elements

A project for the construction of a small-sized bathhouse is one of the most important documents, according to which you can systematically carry out construction processes, calculate the amount of materials, obtain a construction permit, and register the constructed structure for cadastral registration.

Proper planning of a small-sized building will allow you to obtain a large usable area and provide for all the necessary aspects. At the design stage, it is necessary to take into account all the points in order to organize consistent construction without missing deadlines.

How to do it yourself?

The construction of a bathhouse with your own hands at the stage of constructing the foundation, walls and roof is almost no different from the construction of wooden houses.

You will need to do:

• a leisure room (furniture that can withstand significant humidity is placed there);
• shower room (with a floor equipped with drainage devices);
• a steam room, complemented by a stove, is the main room in all baths.

The foundation will have to withstand a relatively small load, so builders can safely choose both columnar and strip structures. Both options are quite easy to do, even if you work on your own, without the involvement of professionals. The installation site is marked, a trench 0.7 m deep is dug on it (regardless of soil freezing), the width is selected in accordance with the cross-section of the beam with a small reserve. The bottom is sprinkled with 10 cm of sand, which is compacted manually using a tamper. This tool is made on the basis of thick logs and handles attached transversely.

The edges of the trench are equipped with formwork, which is most easily made from a shield or board, and are connected by spacers

Please note that the formwork must rise above the ground by at least 0.3 m. Fragments of timber with lower grooves placed on the perimeter of the formwork panel will help to simplify the work

Continuing to work step by step, prepare concrete mixtures and pour them into the trenches, then wait until the concrete sets and becomes dry. In hot weather, the foundation should be protected from the sun and sprayed with water to avoid cracking.

Then roofing felt or other thermal insulation is placed on top of the base. Next you need to build walls from profiled timber. The strapping is made from the most durable material, which does not have even minor cracks. Selected blocks are impregnated with an antiseptic composition, after which the original crown is attached to the foundation with metal pins and dowels. As an option, the bars are placed on the reinforcement installed when pouring the foundation.

Places for the floor joists are prepared by cutting into the crowns. Fastening is carried out using the tongue-and-groove method; adjacent crowns are connected with wooden dowels, which are hammered into the parts being connected. When calculating the number of rows of material, you need to focus on the average height of timber baths of 250 cm. It is recommended to use jute tape rather than linen for sealing. Conventional gable roofs help cope best with accumulating snow.

Work begins by creating nests for the rafter legs, and they are made on the final crowns. The counter-lattice is attached to the rafters, and boards are sewn onto the slats. After that, they deal with the vapor barrier (film saturates the gaps between the rafters) and insulation (mineral wool should cover the vapor barrier layer). Then comes the turn of laying the film, which restrains the spread of water. Finally, it comes to the sheathing, which supports the main covering (OSB sheets are used under bituminous shingles).

Advantages of a wooden house built using timber

• There is no need for interior and exterior decoration of the house. The walls are even and smooth. They look beautiful.
• Moisture does not penetrate the seams located between the crowns. Moisture does not collect on the walls and rot does not appear.
• After a while, after the log house has shrinked, there is no need to caulk.
• The timber has a tight connection with a lock, which protects against blowing.
• Almost no cracks appear and are not deformed during shrinkage.
• Natural material, environmentally friendly.
• Does not require long assembly, assembles quickly, like a construction set.
• The houses have a beautiful aesthetic appearance.
• The house is easy to care for; there is practically no dust collecting on the walls.
• Possibility to paint the house any color.

Calculate a bathhouse: and steam in it, steam, so as not to grow old

How good the frost is!
Eh, hurry up and get on the sleigh! You won't find our Russian bathhouse better in the world!

It has long been the custom that for Russian people, a bathhouse is a symbol of health and pleasure, an inexhaustible source of energy. But before you can enjoy the bathhouse, you will have to work hard - decide what to build it from, draw up a project, calculate the bathhouse so that the construction does not cost a pretty penny by purchasing unnecessary or superfluous materials.

Time will pass from desire to pleasure. And so that it does not drag on for years, in this article we will try to answer pressing questions that interest novice builders.

Third stage

The next stage of the online calculation for the construction of a turnkey timber house is the selection of the base of the building and roofing material.

For a private country cottage, the following types of foundations are offered:

• Pile-screw;
• Strip foundation;
• Support-columnar;
• Monolithic slab;
• Reinforced concrete piles;
• Belt with bored piles.

If you already have a foundation or don’t know which one is best suited for your soil, select the appropriate items in the calculator. The final cost of construction depends on the choice of foundation.

As a roofing material, you can choose ondulin, soft tiles, metal tiles or temporary roofing. To correctly calculate the construction of a timber house using the online calculator, select the appropriate type of roofing.

Bath stove

The basis of good steam is a correctly selected sauna stove. Its power depends on the volume of the steam room, and if you don’t know how to calculate a stove for a bath, you can end up with an extra headache instead of taking a steam bath in comfort.

The furnace power must be calculated in the following sequence:

1. Determine the volume of the steam room - width x length x height.
2. Calculate possible heat loss by multiplying the total area of ​​doors, windows (if any), partitions by 1.2 (heat loss coefficient).
3. We sum up the volume of the steam room and heat loss and get the required furnace power.

With correct calculation, you should take into account the materials from which the bathhouse is built, and the resulting power should be adjusted to standard coefficients. They are in building regulations. For example, for a log bathhouse without lining, K = 1.6, if the inside of the bathhouse is lined with clapboard, and even insulated, such a wall will not absorb heat, on the contrary, it will repel it, therefore K = 0.6.

When starting construction, first of all, calculate the size of the bathhouse, based on whether you are building a “little one” for yourself or planning to organize noisy bathhouse gatherings with friends.

In the first option, you will not need a dressing room, and in general, the bathhouse can be an extension to the house. Well, those who like company will have to spend money and calculate the basic parameters of the structure based on the maximum number of invitees. But that’s what’s good about a Russian bath - it will bring pleasure to everyone. And it will be relatively inexpensive if you build it yourself and correctly calculate construction costs.

Assessment activities

In the process of calculations, you will have to understand how much 150x150 timber is needed for a 6x4 bathhouse, but in addition to the main material, you will need to make calculations of other parameters. This primarily concerns the foundation and roofing. As for the remaining points, they are of secondary importance (see also the article Projects of wooden baths: a review of ready-made solutions).

Calculation of a block base

Most often, during the construction of this structure, foundation blocks are used, which are laid in one row. The calculations are quite simple if you know the volume of elements and the number of laying lines.

Basically, reinforced concrete products are installed in three stripes, which is often reflected in the installation instructions.

1. The first step is to determine the height of the base, but this is done based on the standard thickness of the blocks so that there is an economic benefit. For example, for a 60 cm foundation you will need exactly three rows of 200 mm elements.
2. After this, the area of ​​the entire tape is calculated, and this is easy to do if you know the dimensions of the planned structure. Height is multiplied by length and width. Thus, it turns out: 0.6*4*2+0.6*6*2=12 sq. m.
3. Next, the number of squares in one cubic meter is calculated. To do this, you need to know the thickness of the blocks used. In our case, the elements have a height of 20 cm, so it turns out: 1: 0.2 = 5 square meters. m.
4. Now all that remains is to divide the total square footage of the foundation by the number obtained in the previous paragraph (by the number of squares in 1 cube). This leads to the following example: 12:5 = 2.4 m3.

A table to help you determine the laying depth.

Required amount of timber

It's time to find out how many cubes of timber are needed for a 6x4 bathhouse, since this is the main material for building walls. Initially, it is assumed that beams with a cross section of 150×150 mm are used for the structure.

In the following, calculations are deliberately given only for external walls, since the layout may be different.

1. As in the case of a base made of blocks, the height of the future structure is determined, and it must be a multiple of fifteen. Thus, the height of the object will be: 15 × 16 = 240 centimeters.
2. At this stage, the area of ​​the external walls is calculated, for which the quadrature of each plane is calculated. After this, addition is carried out, in connection with this an example is obtained: 2.4 * 4 * 2 + 2.4 * 6 * 2 = 48 square meters. m.
3. The amount of timber in the cube is determined. As for the thickness of the elements, it is known and amounts to 0.15 m. All that remains is to carry out the calculations: 1: 0.15≈6.7 squares.
4. At the final stage, the total area of ​​the external walls is divided by the number of square meters per cube, resulting in the final result: 48:6.7≈7.16 m3.

Table for determining lumber in a cube.

Roofing area

A roofing system must be present on any building, so you will have to determine the amount of material for its installation. Typically, a 4 by 6 bathhouse made of timber has only two slopes, although more complex roof structures are also found.

Below is an example calculation for a top with two planes.

1. The length of the roof is measured along the ridge or eaves. It is usually 60 centimeters greater than the width of the building itself. For example, this distance in our case will be equal to 4.6 m.
2. The length of the structure from the bottom to the ridge is determined. This distance depends on the height of the roof, so in order to save money it is reduced. Let's say it is 3.5 m.
3. As a result, the numbers obtained using measurements are multiplied, and the intermediate result is doubled, which is explained by the number of slopes. In this regard, it turns out: 4.6*3.5*2=32.2 sq. m.
