Calculation of timber at home. Preliminary calculation of materials for the construction of a house from a bar Calculate the project of the house from the bar

Building a house from a bar is always associated with considerable financial expenses. But that they do not exceed the allotted limit and you have enough materials, you need to calculate the construction of the house from the bar.

Our portal "Repair" offers step-by-step stages of the calculation of a bar for the construction of the house:

	Board consumption at home.
	The formula for calculating the consumption of material for the bearing walls of the construction.
	Material consumption for roof frame house.
	Factors affecting the number of materials required for the roof frame.
	Calculation of the amount of material for the crate and rafters.
	The number of blanks for the device beams.
	Calculation of the amount of floorboard.

Regardless of whether you plan to build housing on your own or for this you decide to hire workers, you need to make a estimate. It is she who will be the basis of all work.
The house of timber contains the following design elements:

• walls;

• roof;

• lags for the floor and ceiling;

• doom;

• rafters;

• fasteners and insulation;

• windows and doors;

• bind.

Board consumption for building a house

For the construction of a house for permanent residence, a ram 150x150 mm, 150x100 mm, 200x200mm or 100x100 mm is used. Before starting work, it is worth choosing the size of the billets and calculate how much the bar may be needed. Typically, calculus pass in cubic meters, and not in pieces.

Form calculating a bar for bearing walls

The calculation of the bar for the construction of the house can be held according to the following formula:

• to begin with, the sum of the length of all walls of the construction is calculated, and not just external, but also internal;
• the perimeter must be multiplied by the height of the house, excluding the fronton (the facade of the building, which is limited by the cornice and ropes of the roof);
• the value you get is to multiply to the thickness of the timber for the construction.

As a result, you will receive the number of cubes that will be needed for the construction of the house. As a rule, limited to one or two floors.

As a result, for the construction of a house you will need 13.5 m 3 of a bar having a cross section of 150x150 mm. If you plan to use more walls, then they are important to consider in the calculations.

For the convenience of building the construction of the house from the bar and facilitate the choice, you can use the data given in the table (with a length of 6 meters):

Section of bar	Pieces in Cuba	Volume of one thing
200х200 mm	4,1	0.24 m 3.
150x150 mm	7,4	0.135 m 3.
100x150 mm	11,1	0.09 m 3.
100x100 mm	16,6	0.06 m 3.

To accomplish the correct settlement of the construction of the house from the bar, you need to take into account what you will not be able to avoid in individual construction - even a proven supplier in one batch will be several marriages. It must be taken into account during the purchase and order blanks with a small margin.

Material consumption for roof frame

For a brusade house, a rafter system is used, which acts as a carrier roof frame. The tree is a solid material, but despite this, it is not necessary to overload, otherwise you can provoke the destruction of the bearing walls and an uneven shrinkage.

The rafal system refers to the category of pitched roofs. Cheaper and easier to build a double roof with your own hands. The technology is available for a novice, and it takes a lot less material.

Factors affecting the amount of material required for roof frame

If you want the roof to be not just beautiful, but also reliable, do not save on construction materials. It is important not to deviate from technology with its independent construction.

The wooden roof frame contains the following mandatory elements:

• rafters or rafter legs;

• fronton consisting of a bar similar to the carrier walls;

• boxes (lags) - horizontally located bars, represent the basis for laying a geepboard;

• mauerlat is a thick layer, which is over the perimeter of the walls, is used for the same distribution of the frame weight;

• the lamp is attached to rafters and acts as the basis for mounting the roof.

How to calculate the cost of building a high-quality house from a bar

According to SNiP 31-02, any roof has a number of requirements, considering which, you need to calculate building materials. That is, that the framework is fully consistent with the stated standards and ensure protection of the house from snow, rain and melt water, did not let the cold air, you need to figure out how much the workpieces need.

Calculation of the amount of timber for the frame: Mauerlat

The amount of material directly depends on the area of \u200b\u200bthe coating. For example, we can consider the house 6x6. For a qualitative base, you will need a thick strong beam 150x150 mm or 150x100 mm. It is placed on four bearing walls, respectively, to make Mauerlat, you need four bars, each 6 meters.

Attention! If the house does not assume the presence of inland bearing walls, it is important that the distance between them does not exceed 8 meters. If another support is located inside the house, then it is worth the distance to 14-16 meters.

For example: 6 + 6 + 9 + 9 \u003d 30 meters.

Perimeter, namely, 30 meters need to be divided into one bar: 30 m / 6 m \u003d 5 pieces.

As a result, for the construction of Mauerlat for home 6x9 m, it is necessary 5 bars 6 meters.

Calculation of the amount of material for crate and rafted

The rafting system is the main support for roofing material that protects the house from snow and wind.

The calculation of the bar, which will go to the construction of the rafter is done according to the following formula:

1. The total load of wind and snow per 1 m 2 roofs - it is calculated on the basis of SNiP 2.01.07-85 "load and exposure". Therefore, for a skate with an angle of 45 degrees, the length of the roof is 6.5 meters and the length of the rafted 3.5 meters the load is 226.3 kg / m 2.
2. Total load - 5148 kg. Now we multiply 6.5 m by 3.5 m and we get 22.75 m, which represents the surface area of \u200b\u200bthe skate (5148 kg).
3. Then you need to find out the length of all rafters and how much it is necessary to purchase a bar for their construction. To do this, considering that 1 mongrel meter can withstand weight per 100 kg, divide 5148 kg on the facilities and get 51.48 m. This will be the minimum length of the rafted.
4. The roof slice hangs over a wall of approximately 50 cm, which means you need to buy wood 4 meters.
5. Calculate the number of pieces very easily: 51.48 / 4 \u003d 12.87, and if more precisely, 14, since they are located in pairs. That is, you will need 7 pairs.

According to the instructions, the distance between the rafters should be equal to the number that it turns out if it is divided by the length of the roof per unit less than the number of pairs of rafted, namely 6.5 / 6 \u003d 1.08 meters. The cross section of the blanks 150x150 mm or 100x150 mm.

The rafter system contains a wooden crate. For it, boards are used by a thickness of about 2.5 cm. They need to be arranged horizontally, namely, parallel to the skate.

In this case, the width of the board should not be more than 15 cm. There are two methods of laying, on which the number of the purchased timber is depends.

The first is a solid laying when the distance is no more than 1-2 cm and discharged. In this case, the flight can reach 10 and more centimeters. The more often the boards will be lying, the warmer and the stronger construction, but at the same time its cost increases.

Calculate the number is very simple. The length of the board and skate is measured. Then the installation of the skate must be divided into the boarding board. Thus, you can find out how much the boards needed for the support strip.

If the width is 15 centimeters, and the gap 5, then the number obtained after the addition should be divided into the skate length. As a result, you will receive the number of blanks.

Calculation of the cost of building a brusade house - a painstaking occupation. Therefore, it is important to take into account the fact that everything needs to be purchased with a margin. Roof consumption is calculated taking into account the surface area of \u200b\u200bthe roof. At the same time, the natural holes are not taken into account - a place for an attic door and a chimney door, if such is in the project.

The overlap from the beams is especially in demand in low-rise construction. They differ relatively low cost, they are quickly and easy to make, the tree is a durable material and has a small weight. It does not give substantial loads on the design of the foundation.

For overlapping from the beams, exclusively wood coniferous rocks is used. In most cases, this is a larch, since it is the most reliable and durable material capable of withstanding high weight:

• good resistance to temperature drops;
• stable tightness;
• practically does not give a shrinkage.

It is necessary to give preference to the best billets that dried in steam chambers and have no more than 14% humidity. In this case, the aspect ratio should be the following 150x200 mm or 150x100 mm.

For proper design to perform a competent calculation of materials for construction from a bar, you need to take into account the width of the span. The more it will, the more often the beams are stacked, and their number increases. To overlap the attic at all, it is not necessary to lay the blanks very close to each other.

We offer to familiarize yourself with the table, which allows you to decide how many pieces it will be necessary:

Split width in meters	Distance between beams in meters	The optimal cross section of the workpiece in mm
3	1	150x100.
4	0,5	150x100.
4	1	150x150
5	0,5	150x200
6	0,5	150x200
7	0,5	150x250

This means that for a flight in 4 m you need to buy 6 blanks for laying overlap beams, pushing out from the step in 1 m. That is, 4 pieces will be used to close the span and 2 will go to the edges near the walls. The cost directly depends on the length of the bar.

Calculation of the amount of floorboard

Before calculating how much the floorboard is needed, it is necessary to determine its size:

• the optimal is the length of 4, 4.5 and 6 meters;
• thickness is represented by the following dimensions: 32 mm, 25 mm and 30 mm;
• standard width - 105 mm or 100 mm.

If you plan to make the floor from the whole boards, it is worth cutting the amount of waste.

The calculation of the material for the construction of the house from the bar is carried out on the basis of the width and length of the area covered and on how the board will be cheated - across or along.

Perform calculations simple enough. If you know the parameters of the workpiece, then you define the useful area, it is 5-7 mm less from the actual as a result of the tongue.

Typically, manufacturers make up 6 meters long boards. It is necessary to take into account the number of waste that you cannot avoid.

Calculations are performed as follows:

• Exercise the famous area of \u200b\u200bthe room on the size of the board area, considering only useful - this is the amount required for laying.
• When the room has parameters other than 6 meters, it is important to consider the amount of the whole material. For this, the width of the room is divided into the working width of the floorboard.

Based on the information received, you can easily learn what approximately the amount will cost you the construction of a bar. At the same time, it is necessary to take into account such consumables as the material for the roof, insulation and additional fasteners. Their number directly depends on the terrain, the project of the house and other factors.

Output

The construction of the house from the bar will be much easier than brick, and accessible to every novice host. By calculating construction, you will get an approximate amount of an object to be focused on budget planning.

Construction of a house from a tree requires a thorough preliminary calculation and compiling the most detailed estimate. Any large building is associated with significant costs, and it is important to initially correctly assess the financial capabilities and represent all future costs.

An important cost of expenses is the foundation, but the most expensive part will be directly the "box" itself, so you need to preliminarily calculate the material on the house from the bar. At the same time, it is advisable to consistent with the professional architect and builders who know the real prices in the materials market.

What timing to choose for construction

Previously, you need to select the material for the house from the bar. It varies both according to characteristics, and in price:

• The cheapest option is the usual ram of natural humidity. He is most common, but the least reliable. In the drying process, it can be significantly deformed, which leads to the formation of cracks and slots in the walls.
• Dried bar - wood material that has passed the preliminary chamber drying. Of it removes most of the natural humidity, so it will be more reliable, but the cost will increase significantly.
• The profiled timber is an even more expensive type of materials that will allow us to build perfectly even walls without cracks between the crowns. A special system of spikes and grooves on the upper and lower sides will make it possible to build a building with the most durable walls.
• Cool timber - leader in value. It is not quite a bar, since it is made not from solid wood, but from several layers of wood, combined with each other. Such material requires a long processing, and it will be very expensive.

Thus, the calculation of the material for the construction of a house from a bar begins with the analysis of the building market and choosing a suitable material. When this question is solved, you can go directly to the calculations.

How many material will need to build a brusade house

The calculation of the material for the construction of the house from the bar can be carried out with the help of a special program-calculator, which are placed on construction sites. This will speed up counting, but the result will still be only approximate. You can calculate the material and manually in the following parameters:

1. Bruse section. It depends on the required thermal conductivity: for the home without additional insulation, a timber is required with a cross section of 200х200 mm: it is quite expensive, so often the future owners prefer to acquire a thinner and cheap material, and then insulate the building with low-cost materials. Build a building for permanent residence permissible from a bar with a thickness of 150x150 mm or 150x100 mm.
2. Dimensions of the house. The standard project is a 6x6 meter building of a bar, as it will allow you to not connect the timing.
3. Height of each floor. The minimum height from the floor to the ceiling is 2.5 m, often it makes it more, then not to limit themselves in choosing furniture and decoration.
4. Square of window and doorways. It is clear that the larger the area of \u200b\u200bthe windows, the less material is required. When developing a project of the building in the drawings, the dimensions of the openings are specified, these values \u200b\u200bare used to calculate.

Example of calculating materials on a standard house

Great assistance when calculating the required number of timber for the construction of the house will be. But let's try to perform simple calculations on a simple example.

Calculation of materials for the house from a bar requires to make enough simple calculations, forcing me to recall the school lessons of geometry.

Preliminary calculation of material on the brusade house:

It is required to build a small house with linear dimensions of 6x6x2.5 meters. For construction, you need to purchase an ordinary timing segment 200х200 mm. In the building it is planned to make a door with dimensions of 800x2000 mm, in addition, there will be two windows with a size of 600x800 mm.

Go to calculations:

• Perimeter at home: 6 * 4 \u003d 24 meters. Multiply this value to the height: 24 * 2.5 \u003d 60 square meters. meters - the total area of \u200b\u200bthe walls.
• Calculate the area of \u200b\u200bthe windows. Multiply 0.8 * 2 \u003d 1.6 square meters. m. - door area, 0.6 * 0.8 * 2 \u003d 0.96 m. - Area of \u200b\u200btwo windows. These values \u200b\u200bshould be deducted from the total area of \u200b\u200bthe walls: 60 - 1.6 - 0.96 - 57.44 square meters. m. - This is the area of \u200b\u200bthe house.
• Since the thickness of the bar is 0.2 meters, the volume of the walls is calculated as follows: 57.44 * 0.2 \u003d 11,488 cubic meters of timber vehicles will be required for construction.

Important moments when calculating the material

If you need to build a house from a bar, the calculation of materials will always be approximate. To the value obtained, it is necessary to add a minimum of 15%, which will be required for cropping, damage, corner arrangement, etc.

The timber is required not only for the construction of the box, but also for the installation of rafters, lag floor, overlaps, etc. As a result, with the final calculations, the amount of timber increases by about the fifth.

The exception is the construction of the house from the finished household complex. In this case, together with the architect, the exact number of materials that will be required for construction is calculated, and all parts undergo pre-processing in the factory conditions.

A ready-made set of numbered parts is received on the construction site, from which the building is erected, like a large designer. All the details are accurately adjacent to each other, nothing needs to be customized and refining. Only fastening elements and insulation will have to arrive, and work can be finished faster.

Calculation of sawn timber must take into account not only the purchase of the timber itself. You will need an incision board for the construction of a draft and fifty for the finishing floor of the specified area, material for the construction of roofing pie and other spending.

Each wooden element used in construction should be processed by antiseptics and antipirens, the finished house needs staining or other finishes. Walls can be seen as drywall and additionally inspire.

Brous houses in comparison with wooden log houses have a number of advantages. Due to the fact that the timber has a geometrically correct form (in the section it is either a square, or a rectangle) in the house there is much more useful space, it is much easier to calculate the number of vehicles necessary for assembling walls.

To do this, it is necessary to fold the length of all the walls to multiply on their height and thickness of the timber, consider an example of formula:

V. bruus = still length h. height of Wall h. bruus thickness

We get the number of bar cubes necessary for the construction of the house.

Correct BROUSE BROUSE

Calculate the required number of timing houses at home 6x9, with a fifth wall, 3 meters high, from a bar of 150x150, for this we fold the perimeter of the walls, not forgetting about the fifth six-meter wall 6 + 6 + 6 + 9 + 9 \u003d 36 rose meters, then multiply on Floor height (3 meters), 36 pose. m. x 3 meters \u003d 108 square meters. meters, in order to get cubic meters, the resulting area multiplied by the thickness of the bar 108 sq.m. x 0.15 \u003d 16, 2 cubic meters. meter.

Here in principle, all, now you should beat it clear how to make the right calculation of the necessary bar for the house, even a schoolboy will look at the described scheme.

Now let's talk how to gather houses from a bar

On the already prepared foundation laid in 2 layers, any waterproofing material, such as rubberoid or only. From above stacked processed (required!) Antiseptic folding boards. These boards serve as a protective buffer between the foundation and the first near Bruusyev. If during the operation will be filmed at the base of the house, then it will be the mortgage boards (they can be replaced), and not the first layer of BRUSEV.

Laying of the first crown

The next step is to lay the first crown of the construction. Here the main thing is to carefully observe the size of the construction along the axes, the horizontal level and measure the corners planned by the project. Here you also need to decide what kind of angular pairing for the bar will be used when it is laying.

The photo shows the laying of the first crown on the foundation

The angles are checked by twine stretched diagonally from the angle to the corner and measure its length. Then they are also stretched diagonally between the second pair of corners. When the distance is coincided, the following crown is stacked. When dispensing - the distance is adjusted. Not applicants are used for these purposes, non-primary means are used for these purposes, but special engineering high-precision tools.

Before assembling the first layer of timber, one of the following types of conjugation of the angles of walls are selected:

• assembly in Polterev;
• building assembly with indigenous spike;
• build on the swords.

Laying subsequent crowns

The second and subsequent layers of the timber are combined between themselves on wooden implicit (wizards), which are a wooden rod, thanks to which the wints are attached in height. Such fixation eliminates the displacement and disintegration of the material of the construction during the sun.

Methods for connecting and adjusting brusides

The hole for the bellows is drilled by several millimeters in diameter more than the heel itself so that the timber can, with a subsequent shrinkage, could freely "walk" on the heat, thereby preventing the formation of the slots.

It does not matter whether you have found a decent construction company or decided to make a house from a bar with your own hands - at some stage you just need to calculate the number of lumber required for its construction. What do you need to know for this? First, how much and what bar is needed to the house. Secondly, how much about it in one cubic meter. And then you can spend the simplest calculation of the cost of building and even make an approximate estimate.

Calculate the amount (consumption) of a bar for a house

Immediately alleged that all the following calculations for the number of timber on the house are approximate. More accurate volumes of the required material can be determined based on the specific project of a wooden house. On the walls of a bar, lumber cubature can be calculated as follows:

• calculate the perimeter of the house;
• multiply the perimeter to the height of the floor;
• the resulting value is multiplied by the thickness of the bar used for the construction of the house;
• as a result, we have the number of cubes that are necessary for the construction of one floor.

If except the external walls are also implied by the presence of internal partitions (also folded from the bar), then additionally take them into account. If you wish, you can calculate not only how much the bar is on the house by volume, but also in pieces. To do this, the volume obtained is divided into the volume of a piece product.

Let us give a specific example: it is necessary to build a small one-storey house 5? 7 m with a simple attic and one partition. The ceiling - 3 m. It will be used with a bar with a cross section, for example, 150? 150 mm. Fronton will also be posted from the bar. Our calculations will look like this:
- Perimeter at home, taking into account the length of the partition: (5 + 7)? 2 + 5 \u003d 33 m;
- volume of the walls of the first floor: 33? 3? 0.15? 15 cubic meters;
- Brous cube, which went to the fronton, we consider it as much as half of the material required to build two walls with a length of 5 m and a height of 3 m: 5? 3? 0.15 \u003d 2.25 cubic meters.
Total to the wall will leave about 17.25 cubic meters. Bruus or, taking into account 20% of the reserve, about 20 cubic meters. m. Material. But it should be understood that here we did not take into account, for example, the beams of overlapping from the glued timber (ordinary or profiled), as well as other features of the design: window and doorways, for example, on the contrary will reduce the need for lumber. Therefore, you can still boldly add 5 cubes. As a result of such approximate calculations, it turns out that approximately 25 cubes of timber will leave for the construction of our house.

How many timber in Cuba

Simple calculations allow not only to calculate the cabbage of the bar on the house, but also to define almost an exact number of bars. Make it easy: it is enough to know the required volume of lumber and the volume of the piece product. It will only be used to divide the first on the second - we get how many pieces are necessary for the construction of the house. Below we presented a table in which the most common sizes of sections with a length of 6 meters were considered.

Brous dimensions

The size of the bar used in the construction of the house is important, but everything needs to be approached from the point of view of economic feasibility. We are, for the most part, the thickness of the walls and thermal conductivity characteristics of the material. Below we consider the question of the thickness of the timber in two cases: during the construction of the summer (country) house and buildings for permanent residence.

Thickness and width

The width of the bar must concern the developer only if permanent accommodation is planned in the house built from it, and it is not always - after all, any wooden wall can be insulated with effective thermal insulation, thereby avoiding losses to the "Street Heating". So, if you plan to build an ordinary country house, then it is quite possible to use the material with a cross section of 100? 100 mm. Using the usual non-stroke material, still have to solve issues with facade facing and interior decoration, shattered, for the most part, with the problems of the aestheticness of the house. But when building a house for PMZ, it is better to use a profiled timber with a width of 150 mm. Warm walls in this case will still have to. As for the thickness, everything is easier - the number of bars needed to build walls just depends on it. But, meanwhile, it affects the number of seams between the crowns. Summarizing the foregoing:

• the thickness and width of the bar for the country house practically does not matter (with seasonal accommodation in a warm course of the year);
• for permanent residence, you can choose the material of greater width, but it will still have to warm the walls. And you can save on the cube of a bar, while making a bet on high-quality insulation - it will be cheaper and more efficient in terms of heat reduction

So, to build a truly warm house only from the bar, the thickness of its walls for the Moscow region should be about half a meter. The same effect will be when using a bar 150? 150 and 10-15 cm of heat insulation.

We draw your attention to the fact that not all manufacturers and sawn timber sellers are honest with their customers: often you can face a situation where the size of the timber section is less than those specified. For example, a ram 150? 200 in fact turns out to be a material with sizes 140? 190 or even less. Be sure to check the actual parameters of the bar before purchase! It will help you not to get to hear, save money and nerves!

Estimation to the house from the bar

Before you decide on the choice of a construction company that will build your home, it is worthwhile to monitor proposals. How to determine the most economically appropriate option? Everything is very simple - to request the estimate to the house from the bar for the selected typical or individual project. In such a defense, all costs associated with the construction of the house should be indicated. This includes the cost of all building materials, and in fact, the fee for the implementation of all types of construction work.

By choosing a few building firms that fabricated you, you should request the estimate to the house from the bar. Normal companies offer them for free. It is noteworthy that different firms estimates on the same buildings may differ not only by 10-20%, but at times - everything depends on the appetites of builders. It is desirable to have in your hands the most detailed list of works and materials required for the construction of the house according to your project. Only so you can avoid unforeseen expenses, which usually pop up at the construction stage.

If desired, the estimate of the house can be compiled independently: for this it is necessary to calculate the flow rate of all materials and multiply their amount per average price. This will have to be added to the amount of in about 50-100% of the cost of building materials - the price of work. It will be very close to calculate the cost of the house of the bar, but it can be used to analyze offers from relevant companies.

When the idea to build a house approaches the stage of practical actions, it always necessitates the counting of the required amount of material. Accurate calculations are carried out on the project of a particular home (see).

1. Calculation of the perimeter of the house by adding the lengths of the outer walls.
2. Obtaining an area of \u200b\u200bexternal walls of one floor, multiplying the perimeter with the height of the walls.
3. Calculation of the number of cubes, multiplying the area with a width of a bar.

So the material required for one floor is obtained. When the house is planned to establish internal additional partitions from the bar, then they should also be considered. Knowing the total volume of material in 1m³, you can calculate it in pieces.

And so the formula for counting the volume of the bar in cubic meters:

• p - the length of the walls of the house (meters).
• h is the height of the walls (meters).
• l is the thickness of the bar (meters).

On the example of the house (dimensions of 6 × 9m, 6 meters, an additional inner wall, height 3m, a timing of 0.150 × 0.150m), the calculation of the required material on it looks like this:

• p \u003d 9 + 9 + 6 + 6 + 6 \u003d 36m.
• h \u003d 3 meters.
• l \u003d 0.150 meters.

After multiply, the volume of the required bar is obtained:

V \u003d 36 m * 3 m * 0.150m \u003d 16.2m³.

Calculations of the volume of building materials are slightly complicated, if for the construction of a house from a bar need a material of different lengths and sections. Then first calculates the volume of the vehicle of each section, and the values \u200b\u200bare folded.

The most running material has a length of 6m, the wall in the example is longer, then they plan the capital wall, which is made carrier.

The size of the bar, of course, plays a role, but it is important to estimate economic feasibility and take into account the thermal conductivity parameters of the material.

Brous width becomes relevant when year-round accommodation is planned in the house, but any house can be insulated with high-quality thermal insulation. When it is planned to build a cotton house, you can choose a material with dimensions 0.100 × 0.100m.

It is possible to calculate the volume of one bar, moving its width, thickness and length. Then the volume of the six-meter bar is 0.150 × 0.150m. It has a volume of 0.135m³. After calculating the total volume and number of timber in 1 cube, you can estimate the approximate value of the material.

The most accurate calculation of the volume of the bar is carried out if the area of \u200b\u200bwindows, doors, and the resulting value obtained to the known thickness of the timber are taken from the walls of the walls.

We must know that when the house is built from a profiled bar, then 10mm. The crown "includes" into the profile and requires a larger amount of material than calculated according to the above methods.

Not taken into account in simple formulas and the length of the releases formed when the "in the bowl" ringing, they also increase the common cub.

Conducting calculations, you can also determine how many pieces of timber is needed to the house, dividing the total amount of material (cubic meters) to the volume of one product.
