Calculator for calculating the cost of a log house with siding, slab prefabricated-monolithic foundation, wooden-beam ceiling, ondulin roof. Calculation of a house from a bar Calculate how much timber is needed for a house calculator

Many people think about building a country house, but most people postpone it until tomorrow due to ignorance of how to calculate the amount of timber per house. Why? Yes, because the counting process itself is not free, and no one wants to pay for something that may not be realized.

Let's try with you to understand how to correctly calculate the amount of this product for construction yourself.

Calculation of a product for the construction of a building

Factors that affect the numbers

The main thing to consider when calculating the amount of material per house is:

• what type of timber will be used in construction;
• how much we need;
• how many pieces in 1 cubic meter;
• what .

Calculation of lumber in cubic meters

Let's consider how to calculate the amount of timber in a cube in the simplest way, we can say that this is the basic principle of calculations. It should be noted that the above example is not exact. To draw more accurate figures, you need to have a project of the future home.

So, attention instruction:

1. Calculate the perimeter of the building.
2. Multiply the perimeter by the height.
3. The result obtained is multiplied by the thickness of the product.
4. As a result, the result of the number of cubes of timber required for the construction of the building is obtained.

To calculate the product for interior walls, we use the same method. If desired, you can calculate not only the cubature of the material, but also its quantity in pieces. Consider a separate example of how to calculate the amount of timber per bath 3 m by 5 m 3 m high.

We agree that the size of 150 by 150 mm will be used during construction.

Instruction:

• (3 width + 5 length) × 2 = 30 m - the perimeter of the building.
• 30 perimeter × 3 height = 90 sq.m - wall area.
• 90 area × 0.15 material thickness = 13.5 cubic meters - needed to build a box from a 3 × 5 beam 3 m high.

Thus, the amount of timber for the walls is 13.5 cubic meters. But, it should be noted that window and door openings will reduce the amount of material used.

In most cases, the masters do not take this moment into account, it is believed that it would be even better to throw about 20% on the stock, in the end we will get:

• 13.5 + 20% = 16.2 cubic meters will be required for this type of building.

Note!
When building a house from a bar, the first crown should be slightly thicker than the main product used to build walls.
In our calculation, it is not taken into account, it must be calculated separately.
The first crown is laid from a thicker one, since in the future the mass of the whole house will fall on it, it is additionally recommended to treat it with machine oil or an antiseptic.

Calculation in pieces

By calculating how many cubes of lumber for building a house, you can easily find out how much timber is needed in pieces. This is the first thing you need when buying. Knowing the exact number of pieces, you will protect yourself from possible fraud by the seller.

Consider a table of common sizes for this 6m long product:

In the above example, where we indicated the cubature of the beam for the bath, we will carry out a further calculation of materials in pieces.

So, in order to find out the amount of material per house in pieces, we carry out the following calculation, for this the sum of 13.5 cubic meters, which is needed to build a bath, we divide by the cubic volume of the used timber, in our case it is equal to 0.135 cubic meters based on the table :

• 13.5: 0.135 = 100 pcs

Knowing the correct quantity of the product in pieces, you will not have to run around with a tape measure and calculate the volume when buying to find out if you received the material according to the invoice correctly, you will only need to count the product by the piece.

The role of the height and thickness of the material

Before calculating the quantity, you need to decide on the choice of thickness and height of the product.

The material can have different thicknesses and heights, we list the main dimensions:

• 100x100 mm.
• 100x150 mm.
• 150x150 mm.
• 150x200 mm.
• 200x200 mm.

With a height, everything is simple, the higher the beam, the fewer interventional seams - construction work is faster, and naturally, the number of pieces of material for building a house decreases. But the width is more important, especially when building for all-season living.

Note!
Not all lumber manufacturers are honest with the buyer, sometimes it happens that a 150x150 mm beam actually has a size of 140x140 mm.
It’s not difficult to guess what this will lead to, if a beam of 150x150 mm in size is needed for a height of 3 meters, 20 pieces, then with a size of 140x140 mm - 21 pieces and a half, and this is one and a half crown rows.

When planning year-round living in the house, it is recommended to use a beam with a thickness of 200 mm. It is necessary to insulate such walls, but for our climate, such as polystyrene foam or mineral wool 10 cm thick is enough.

When building a bath, it is recommended to use a material thickness of 150 mm, it is quite enough to maintain the temperature for a short time. Well, if you decide to build a country house for a summer holiday, then in this case, the walls of a 100x100 mm beam will be just right.

Advice!
During the construction of a wooden house, in which it is not planned to live all year round, the thickness of the timber is not important.
After all, such a building is needed only for short-term use and mainly in the spring-autumn period.

Pay attention!
Despite the large thickness of the product, you still have to insulate the walls.
Indeed, in order for the house to fully fulfill its thermal insulation properties, the thickness of the walls should be about 50 cm.

Why do you need a house project

When calculating the material for building a house, the design of the house itself plays an important role. After all, only in the finished project you can see not only the appearance of the building, but also the internal arrangement of walls and elements that need additional calculation of the necessary material.

You can get a project of a wooden house in different ways:

• do it yourself;
• order from a specialist;
• buy a finished project;
• buy on the Internet;
• find on the internet.

It is possible to make a project at home with your own hands, but it is difficult, since you must have special knowledge. And the point here is not only to draw a future house, you need to take into account the specifics of the climate, soil, air humidity and other points.

The most correct decision is to order a project from a specialist, the price for such services is not cheap, but this is the best option, the specialist will take into account all your wishes and the possibilities of the area. This will protect against many possible troubles, and will also have someone to ask if problems arise.

Advice!
Do not buy projects on the Internet from unverified persons, most often they sell those projects that are posted on the Internet for public use.

Output

By making the right calculations, you will ensure an easy construction for yourself. There will be no need to think later - where to put extra products or, worse, suspend construction due to their shortage.

If you still have any questions, watch the video in this article, you will not only learn how to calculate the timber on the calculator, but also be able to calculate the approximate cost of the future home. You definitely will not have any doubts about your ability to calculate the material with your own hands.

Lumber is one of the most sought-after materials for construction at the moment. The scope of application is simply huge. Directly at the construction site, lumber is used at almost every stage, it is included in the full cycle of general construction works, from foundation formwork to load-bearing structures on the roof. This type of material is very unpretentious in use, which makes working with it indispensable and enjoyable.

Features of the calculation of lumber:

This lumber calculator helps you quickly calculate from pieces to m3 and vice versa. For the calculation, you must specify the length of the board or beam in millimeters (S1). Width and thickness (S2/S3), and if necessary, you can immediately find out the cost of the calculated lumber by filling in the appropriate field. You can check the cost of the forest with any supplier in your area, or at the nearest construction market. Usually the price is indicated per cubic meter, and this calculation script will play an indispensable role here. After all, agree to calculate the cost of several boards, when they tell you the cost per cube, it is quite problematic.

Having mastered this cubic capacity of lumber, you will no longer be faced with the question of how to count lumber. Entrust the routine calculation to the lumber calculator, and you will not only save your personal time, but also eliminate errors in calculations, which will definitely lead you to save money.

What types of lumber are

• Edged board is perhaps one of the most popular materials in the building materials market. This type of material is used everywhere, in the construction of houses, baths, utility rooms, individual structural elements such as stairs, fences, windows, doors, roofs, and so on. Our specially designed program will help you calculate the cubic capacity of boards in a cube. Keep this page bookmarked, and you will always, quickly and conveniently, be able to calculate any wood.
• A bar is a product of rectangular or square lumber, just like a board, it has extensive use not only in the construction market, but also in furniture production. When buying this material, it is easy to fall into the tricks of unscrupulous sellers. In addition to its humidity, clear overall dimensions, class and quality, cunning managers can easily cheat you on the total volume. Do you know how to correctly calculate the cubic capacity of a bar? Just use this online cubage lumber calculator and save your nerves and money.

An online calculator for calculating the amount of timber per house can now be found on the website of any major seller of building materials. But if for some reason the calculator is not available - how to calculate the amount of timber per house manually? Obviously, we will have to remember the half-forgotten course of school geometry.

If several sizes of lumber are used during construction, the calculation of the amount of timber per house is performed separately for each of them. Let's say, with a beam of 200 * 200 and internal partitions made of a material with a section of 100 * 100, we separately calculate the volume for the capital enclosing structures and for the partition.

Negligible quantities

As you can see, without using an online calculator, it is not difficult to calculate how much timber you need for a house.

However, it should be understood that with the above calculation scheme, we deliberately neglect some of the subtleties of construction:

• The actual volume of each wall will be somewhat less than the calculated one due to the fact that the rectangular parallelepipeds representing the walls partially intersect in space;
• In addition, we completely neglect window and door openings (with the exception of floor-to-ceiling panoramic windows).

The reason why we ignore these points is very simple: none of these factors affect the volume of purchases.

As a rule, when designing and building a log house with your own hands, the dimensions of the structure are deliberately made a multiple of the length of the lumber that is supposed to be used.

Additional segments are used in construction extremely rarely, because they:

1. Reduce the mechanical strength of the log house, its ability to withstand deforming loads;
2. Deteriorate the thermal insulation of the building due to blown seams;

It is worth clarifying: the insulation strongly depends on the method of cutting adjacent segments.
A half-tree horizontal connection is really blown by all the winds, but it is worth deploying it vertically - and in terms of thermal insulation, the connection will not differ in any way from a solid crown.

1. They require unjustified time to perform unnecessary connections.

reference Information

Lumber at large volumes is bought and sold by cubic meters. The price is indicated by the seller exactly per unit of volume.

However, in some cases, the buyer needs to purchase a small amount of timber, measured in units. The most typical example is the purchase of materials for beams or a floor lag: it is much easier to count the number of beams with a known step than their total volume.

In this case, the following table, which is relevant for a measured length of 6 meters, may be useful to him.

Calculation examples

Task 1

We are already familiar with the instructions for performing calculations; it remains only to follow the above algorithm.

1. The perimeter of the house is 6*4=24 meters. The area of ​​the outer wall is 24*2.7=64.8 m2;
2. The horizontal section of the beam in SI units corresponds to 0.15 m;
3. The volume of the walls, therefore, is 64.8 * 0.15 = 9.72 m3.

Task 2

Let's complicate the task, still not using a calculator: how to calculate the number of cubes of timber per house measuring 12 * 12 * 3.5 meters, if the outer walls will be built from lumber with a section of 250 * 250, and the internal cruciform partition dividing the building into four equal room area - from a bar with a section of 100 * 100 mm?

It is easy to guess that in this case the area of ​​​​the outer walls and the partition will be the same. Let's calculate this area: 12*4*3.5=168 m2.

Now we translate the thickness of the walls into SI values:

• 250 mm = 0.25 m;
• 100 mm = 0.1 m.

So, we need 168 * 0.25 = 42 cubic meters of material of a larger section for the outer walls and 168 * 0.1 = 16.8 m3 of 100 * 100 timber for the partition.

Tip: in practice, it is better not to increase them to improve their heat-insulating qualities, but to insulate the house from the outside with mineral wool boards.
Thus, the owner will receive better insulation at a much lower cost.

Task 3

• The height of its two floors is 6.5 meters;
• Dimensions - 6 * 12 meters;
• The thickness of the outer walls is 200 mm (beam 200 * 200);
• The thickness of the partitions is 100 mm, the height is 3.1 meters, and their total length on both floors is 92 meters;
• The house has three floors on beams measuring 150 * 100 mm, laid in increments of 1 meter.

Let's break a relatively complex problem into several stages.

1. We calculate the volume of lumber for the outer walls of the log house. It is equal to (6+6+12+12)*6.5*0.2=46.8 m3;
2. We calculate the volume of material for the internal partition. 92*3.1*0.1=28.52 m3;
3. We count the number of beams. With transverse laying, 13 pieces will go into each floor (the first and last beams are located directly near the walls parallel to them); for all three floors you will need 13 * 3 = 39 pieces;

All project cards on our website have a detailed description and approximate cost of the finished house. But you can calculate the timber for a house or a bath using a calculator by changing the thickness of the walls or making other changes. To use the calculator, select the following options:

• type of building (house or bath);
• complete set (turnkey or shrink);
• log house project (select from our catalogue);
• beam section (90x140 mm, 140x140 mm or 190x140 mm);
• foundation design (pile-screw, strip, etc.);
• ceiling height (number of wall crowns);
• type of interior decoration (lining, block house, etc.);
• type of exterior finish (lining, block house, etc.);
• insulation of floors and roofs (knauf, rockwool of various thicknesses).

You also need to fill in the fields: type of windows, roofing material and other data. Our calculator for calculating the beam will help you solve the main issue of construction - how much will the finished log house cost?

Of course, during construction it is very important to correctly calculate the right amount of materials. After all, each log costs a lot of money, and its transportation is associated with certain difficulties. And if an error was made in the calculations, this can lead to serious difficulties. Our online lumber calculator will help you do this online.

With a lack of material, you have to interrupt the construction process, and wait until the timber is delivered in the right amount. If too much timber was bought, then there will be a few extra logs, the money for which was thrown to the wind.

But if, when calculating, you use a calculator to calculate the amount of timber, you will get the most accurate result. It is also important that the calculator is very easy to use, thanks to which even an inexperienced person will be able to carry out the necessary calculations in the shortest possible time.

First you need to enter the approximate dimensions of the future house - the height, length and width of the walls. Of course, to know this data, you need to have

Only then will you be able to use accurate data.
The next step is to choose the length of the beam. The beam can have different lengths, usually from 5 to 12 meters. This allows you to choose the optimal length for any project without overpaying extra money and without wasting time connecting two elements.
The last stage is an indication of the cross section of the beam.

In private construction, a bar with a section from 150x150 to 200x200 is usually used. The choice of a suitable timber depends on the desire and capabilities of the future owner of the house.


But it is worth noting that the thicker the beam, the better heat and sound insulation characteristics it will have. However, at the same time, the cost of building material also increases. So, you should seriously approach the choice of material so that it meets not only your requirements, but also its cost does not make the material inaccessible to you.
