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

If several standard sizes of lumber are used during construction, the calculation of the amount of timber per house is carried out separately for each of them. Let's say, with timber 200*200 and internal partitions made of material with a cross section of 100*100, we separately calculate the volume for the permanent 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 your house.

However, it is worth understanding that with the above calculation scheme we deliberately neglect some of the subtleties of construction:

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

The reason we ignore these points is extremely simple: none of these factors affects 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 multiples of the length of the lumber that is supposed to be used.

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

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

It is worth clarifying: insulation strongly depends on the method of cutting adjacent sections.
A horizontal connection in half a tree is indeed blown by all the winds, but if you turn it vertically, in terms of thermal insulation the connection will be no different from a solid crown.

1. They require unnecessary time spent on unnecessary connections.

reference Information

Lumber in large volumes is bought and sold by the cubic meter. 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 floor joists: it is much easier to count the number of beams at a known pitch than their total volume.

In this case, he may find the following table useful, relevant for measured length at 6 meters.

Examples of calculations

Problem 1

The instructions for performing calculations are already familiar to us; All that remains is to follow the above algorithm.

1. The perimeter of the house is 6*4=24 meters. Square outer wall— 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 is thus 64.8*0.15=9.72 m3.

Problem 2

Let’s complicate the task, still without using a calculator: how to calculate the number of cubes of timber for a house measuring 12*12*3.5 meters, if the external walls are built from lumber with a cross-section of 250*250, and the internal cross-shaped partition dividing the building into four equal sections room area - made of timber with a cross section of 100*100 mm?

It is not difficult to guess that in this case the area of ​​the external walls and the partition will be the same. Let's calculate this area: 12*4*3.5=168 m2.

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

• 250 mm = 0.25 m;
• 100 mm = 0.1 m.

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

Advice: in practice, it is better not to increase them to improve their thermal insulation qualities, but to insulate the house from the outside with mineral wool slabs.
Thus the owner will receive better insulation at much lower costs.

Problem 3

• The height of its two floors is 6.5 meters;
• Dimensions - 6*12 meters;
• The thickness of the external walls is 200 mm (timber 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 1-meter increments.

Let's break it down comparatively difficult task at several stages.

1. We calculate the volume of lumber for the external 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. When laying transversely, each floor will require 13 pieces (the first and last beams are located directly next to the walls parallel to them); for all three floors you will need 13*3=39 pieces;

Having come close to the cherished goal - to build wooden house, you should familiarize yourself with the quality characteristics and procedure for calculating timber. Selecting high-quality lumber that meets construction standards and correctly determining the required quantity is the primary task of a difficult path.

Types and purpose of timber

Housing construction is carried out using glued or profiled timber. The quality characteristics of the product depend on the production process of the material. Source of profiled timber – conifers trees. Depending on the size and purpose of the building, 3 main options for standard timber are used:

• a summer cottage or bathhouse is built from material with a cross-section of 100/100 mm;
• for medium-sized permanent housing, products with a cross-section of 150/150 mm are suitable;
• Cottages or houses of impressive size are built from 200/200 mm timber.

The length of the product is usually 6 m. It is possible individual order material with non-standard sizes. Front side timber can be arched or straight. Products are processed on machines with subsequent grinding of one side. Its location inside the home allows you to avoid subsequent wall finishing. The presence of spikes at the end of the beam provides an increase in the level of protection from moisture and cold of the future building, and also facilitates the process of its construction. Having completed the installation stage of the log house, it is given time to settle for shrinkage for a year. Pre-drying the timber in specially equipped chambers allows you to speed up the process by several months.

The production of laminated veneer lumber is significantly different:

• The log is pre-cut into pieces called lamellas.
• The boards are processed on planing equipment and placed in drying chamber, where in a gentle mode the moisture content of the material is reduced to 10%.
• The material is re-planed, sorted and glued into timber using special waterproof compounds using hydraulic equipment.

Note! Laying boards opposite to the cross-section of the fibers relative to the adjacent product increases strength finished material and resistance to rotting processes. These actions bring laminated veneer lumber to a leading position in terms of strength relative to profiled products.

It is possible to improve the strength indicator by using profiled larch material, but this significantly increases the cost Supplies. In glued materials, there is an option when one larch lamella is combined with less expensive species during pressing. This trick allows you to increase quality characteristics laminated veneer lumber with a slight increase in its cost.

What other differences are observed in the material when in different ways production?

• The glued version is characterized by humidity around 10%. Pre-drying of the profiled product makes it possible to reduce the indicator to the level of 20%, which is the reason for the increase in construction time due to the longer shrinkage of the finished log house. However, a solid product is not subject to cracking, and with the glued production method there is a risk of minor cracks.
• Focusing on the significant difference in cost (profiled products are almost half the price of their glued counterpart), do not forget about subsequent finishing. Lamels are often left without additional processing, while they try to hide the profiled material with additional decor.
• Delving deeper into the issue of environmental safety, it is worth noting that profiled timber is completely harmless. The owner can independently select special impregnations that provide protection against rotting and fire. The connection of the lamellas is carried out by using adhesive composition, the quality and safety of which lies solely on the conscience of the manufacturer. Therefore, there is a possibility of chemical fumes causing negative impact on the condition of the residents.

As can be seen from the description, each of the materials has significant advantages and certain disadvantages. Stop at optimal option Only the owner of the upcoming construction is capable.

Methodology for calculating material for building a house

When designing housing made of timber, it is worth taking it into account standard sizes to minimize waste. In addition to the material for the log house, material will be needed for the pediment, partitions, floor and ceiling beams.

Basic calculation formula

Calculation of timber cubic capacity uses the following parameters:

• Section of timber. For the house they mainly use 150/150 mm timber; the additional use of insulation makes it possible to ensure comfortable conditions For permanent residence V middle lane Russia.
• Housing dimensions: height and width, houses, number of partitions, rafters, floor and ceiling beams.

Let's say for one-story house 6x9 with a room height of 3 m and one partition you will need:

• We determine the perimeter: (6+9)x2 + 6 = 36 m;
• We calculate the total area: 36x3=108 m;
• Required timber volume: 108x0.15=16.2 m3.

Some amount of material is saved by cutting out door and window openings. However, when purchasing, the volume of timber is always rounded up, taking into account the likelihood of defective products.

Calculation of volume for floor and ceiling beams

The amount of material required for beams, joists and other elements directly depends on the size of the house and the type rafter system. For ceiling and floor beams, 100/150 mm timber is sufficient. Referring to the dimensions of the future structure described above, calculating the amount of timber for the floor and ceiling separately includes the following steps:

• With a distance between beams of 1 m, the number of products: 9/1-1=8 pieces;
• At standard length 6 m, required: 8x6 = 48 m of timber;
• We determine the volume: 0.1x0.15x48=0.72 m 3 ;

Taking into account rounding, in general, 1 m 3 of material will be required for the floor and ceiling beams.

Rafter system

In suburban housing it is mainly used gable roof. It is important to design the slope correctly: small angle will provoke snow retention; with an excessively high roof, the wind load increases. It is optimal to stay at 45 degrees. The recommended pitch between the rafters is 0.6 m, the timber is taken with a cross-section of 100/150 mm. More frequent pitches allow smaller thicknesses to be used. So:

• Using the Pythagorean formula, we determine the length rafter leg, based on the width of the house being 6 m. It is equal to 4.2 m; the triangle will take 8.4 m of material.
• Taking into account the length of the future housing, the number of triangles: 9:0.6-1=14 pieces;
• Total length of material: 8.4x14=117.6 m;
• Volume of material with a cross section of 100/150 mm: 117.6x0.1x0.15=1.76 m3.

Don’t forget to make a supply of material taking into account possible waste. The easiest way to check the accuracy of your calculations is to use an online calculator. A more accurate answer can be obtained from the developer. Some companies provide cost estimation services for free.

A beautiful dacha is the dream of every summer resident. For a resident of a modern metropolis, a dacha is almost the last refuge of nature and an opportunity to bring their creative impulses and fantasies to life. Everyone wants their plot to be unique and comfortable, so that the eye is pleased with their favorite beds and flower beds, and the neighbors look with envy and delight.

Of course, you can hire a landscape designer, but it’s much more interesting and pleasant to do beautiful dacha. Each of us has a craving for creativity, which we are not always able to realize, so why lose the unique opportunity to express ourselves and do everything on our site the way we want. Let everything at your dacha be the way you want it. Photos of beautiful dachas on our website will help you generate new ideas in dacha design.

How to make it beautiful at the dacha? The main advantage of any dacha and its decoration are. It is important to plant the plants correctly, because in a large area they will be visible from all sides and your mistakes will be much more noticeable. Water, air, heat and light are the main factors on which the development and growth of plants depends. They are closely interrelated and do not replace each other. Therefore, in order to make the dacha beautiful, you need to create appropriate conditions for the plants. Plants in closed ground poor lighting need low temperature. Better to plant more unpretentious plants one species rather than trying to grow exotic but capricious species. How to make your cottage beautiful

Shrubs are less demanding to care for, so they are perfect for decorating your garden. An excellent decoration for your site can be a pond, which, if necessary, can be used for irrigation, because the water in the pond warms up perfectly in the sun. A forest corner looks great in a dacha. A shady space will give you a lot of joy on hot summer days. How to make it beautiful at the dacha

When creating a beautiful dacha with your own hands, do not forget to choose plants that are suitable specifically for your site. Moisture-loving plants planted in dry soil may wither and die. Most plants do not like excess moisture as well as lack of it. With very strong and frequent watering root system the plant begins to suffer due to the lack of oxygen, as a result of which it weakens, the plant gets sick and soon dies. Therefore, soils that can retain water after watering or rain are not used for growing flowers or special soil drainage is created.

For the garden it is necessary to prepare a sunny area and Special attention It is worth paying attention to paving, do not use recycled materials. This will be especially important if your garden is visible from the second floor; you risk spoiling the view from the window for yourself and your neighbors. Smooth and beautiful paths will make you personally feel like spring and autumn. It is during this period that they will be responsible for the attractiveness of your dacha.

Of course, during construction it is very important to correctly calculate the required 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 beam calculation calculator will help you do this online.

If there is a shortage of material, you have to interrupt the construction process and wait until the timber is delivered to the right amount. If too much timber was purchased, then there will be a few extra logs left, the money for which was wasted.

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

First, you need to enter the approximate dimensions of the future house - 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 stage is choosing the length of the beam. The beam can have different lengths, usually from 5 to 12 meters. This allows you to select optimal length for any project, without overpaying extra money and without wasting time connecting two elements.
The last stage is to indicate the section of the beam.

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


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