Wall made of timber material with siding profile finishing and internal heat insulation

Timber wall

The features of timber-timber housing have been proven to neutralize toxic substances, automatically regulate humidity levels in the range of 45-55%, and also have a beneficial effect on the psyche of residents.

The popularity of timber-log architecture in our country is predetermined by the cost-effectiveness, traditionalism and healthy environment of house-building from natural solids.

On construction bases It is possible to find timber products of standard sizes 150x100, 200x150, 100x100, 140x140, 180x180, 150x150, 120x120, of which the most popular type is 150x150, since it provides the optimal combination of installation complexity, specified by the quantity horizontal seams, and thermal insulation qualities, as well as an affordable price.

It should be added that now the share of sales of profiled, in particular, prefabricated laminated timber is clearly growing, which is characterized, in comparison with non-laminated wood, by 10 times lower compressibility when drying, as well as increased, due to tenoned joints, structural and thermal insulation qualities . An obvious negative point that slows down the widespread use of laminated veneer lumber material is its significant cost, which, however, is compensated a hundredfold by its long service life.

Approximate procedure for laying a timber frame:

First, on top of the foundation, covered with waterproof material, along the line of the walls, the lower row of timber is laid out, which is tied “into a paw” at the corners and at the points where intermediate walls are connected.
To prevent door and window structures from deforming during the shrinkage of a wooden house, the door and window niches are surrounded on the sides with “windows” - profile posts. To do this, a trapezoidal tenon is cut out at the ends of the logs, onto which the so-called profiled beams are pushed, using a counter cutout. Technological gaps are placed along the top of doors and windows, filled with flax-jute or basalt insulation.
During the installation of a log house, log rows are covered with an inter-row compactor: felt, jute, flax jute, hemp, flax wool, tow, which after a year (or when the humidity of the tree becomes 12-15 percent) will have to be compacted a second time in order to reduce heat loss through the gaps between logs.
In order to connect the beams of the nearest crowns, dowel fastenings are used (rounded birch or oak rods with a diameter of 30-40 mm), which are inserted with a gap into the holes made through the three crowns of the beams, in increments of 0.3...0.4 m. Often, dowel fastening is replaced with large nails (250...300 mm), with obligatory drilling in the last log of a channel, 30÷40 mm deep, where the nail head is buried to compensate for linear compression wooden material when drying out.
When choosing interior decoration it is necessary to take into account the permanent deformations of the wooden material and, when fastening non-wooden facing boards (for example, plasterboard), avoid direct connections with timber wall, through the installation of suspended buffer profile structures.

Siding cladding

In cases where winter habitation is expected, it is recommended that the timber structure be further insulated. Typically, on the street side, in a vertical position, thick boards, 100x50 mm in size, are mounted in increments of 0.4...0.6 m, between which heat-insulating mats are installed, for example, such as: Rockwool, P-175, Isomin, Isover, P -125, PPZh-200, Ursa, Knauf, Izorok, after which a vapor-permeable film (Tyvek, Yutavek, Izospan) is stretched, lined with blocks, 25-50 mm thick, on which the front false wall is installed (PVC siding, wooden lining or slabs DSP).

You need to know that the PVC siding profile will be used for many years and have a beautiful appearance only if the installation rules are strictly followed.

Manufacturers of plastic siding profiles, for example, brands: Snowbird, Gentek, Docke, Nordside, AltaProfile, Orto, Holzplast, Tecos, Varitek, Georgia Pacific, Mitten, FineBer, Vytec, announce a rich color scheme, allowing any building to maintain its individuality.

Since the polyvinyl chloride siding profile greatly changes linear dimensions When temperature fluctuates, it is important to provide for non-rigid attachment of vinyl plates.

PVC siding does not rot, is resistant to impact, biological, and climatic aggressions, and does not support combustion.

Vinyl profile exposed open flame it only melts, igniting when heated to more than 390°C (and wood is already at 230-260°C), quickly extinguishing when the heating source disappears, while the amount of emissions hazardous to health is no more significant than when burning wood materials.

Important points for fastening PVC siding:

The installation of PVC panels is carried out “from the ground”, and first the hidden starting strip is fixed.
To compensate for free compression or expansion of polymer siding, gaps should be provided, within 1 cm, in areas where external networks enter (pipes, wires, brackets, cables), as well as in joining areas plastic panel and accessories ( external corner, internal corner, H-profile, platband, etc.).
It is unacceptable to forcefully tighten the screws in the fixing grooves, because the siding profiles are suspended in such a way as to move freely from side to side.
In order not to interfere with thermal movements and, accordingly, not to provoke wave-like warping vinyl material, it is more correct to screw in self-tapping screws and nails into the siding panel at the central point of the existing technological perforations.
When hanging another strip of siding, attach it to the trailer ledge with the underlying profile and, without deforming it, secure it with screws;
It is recommended to install vinyl profiles starting from the side wall of the building, moving to the front side, while each successive siding panel will overlap the previous one in the laid row, approximately 2.5-3 cm - this approach makes it possible to make the joints inconspicuous, with For the same purpose, the resulting joints for connecting rows need to be shifted horizontally.

Foundation made of reinforced concrete slab and prefabricated block tape

A prefabricated slab foundation is constructed over the entire area of the structure in the form of a continuous reinforced slab on which standard reinforced concrete blocks are mounted.

The type of foundation under consideration is used in low-rise housing construction to obtain the basement level of the house, on heterogeneous soils, in situations low level groundwater. In swampy areas, it is recommended to construct the side walls of the foundation using a monolithic method, using waterproofing measures (coating, impregnation, gluing).

At the same time, the prefabricated block system of vertical foundation walls, according to the existing reinforced concrete slab, is indispensable for limited construction periods, as well as for foundation work in winter.

An approximate method for performing a whole- slab foundation side walls in the form of prefabricated reinforced concrete strip:

First, the ground is removed to the planned level.
Gravel preparation, fractions 20-40, in a layer of 15-20 cm is poured onto the resulting base and compacted thoroughly.
Concrete is poured in a layer of 50 mm.
A waterproofing film is applied with a distance of 2000 mm along the border, for the purpose of further waterproofing the sidewalls of the foundation.
To protect the waterproofing membrane from accidental ruptures when welding the reinforcement structure, another layer of sand-cement mortar, 5 cm thick, is applied on top of the insulating coating, along the perimeter of which formwork panels are mounted according to the thickness of the foundation slab.
The foundation slab being manufactured is tightened from the inside with two meshes of welded reinforcing bars of section d14, type AII-AIII, with cells of 20x20 cm.
In the case of a slab foundation, ready-made concrete of a grade not lower than M300 is required, supplied by an automixer.
The hardening time of the concrete solution, when the perimeter should be laid out from ready-made concrete blocks, is from 4 weeks, at a temperature of + 15 ± 5 °.
The laying of concrete blocks is carried out relative to the axial lines, along two mutually perpendicular walls, guided by geodetic equipment. Prefabricated blocks are laid with a crane on a “bed” of sand-cement mortar.
Installation begins with laying beacon blocks at the crossroads of the axes and at the corners of the building. The laying of wall blocks begins only after the position of the reference blocks has been verified along the horizon and level.
On the top row of reinforced concrete blocks, in a panel formwork form, a reinforced reinforced concrete screed, 25 cm thick, is made.

Floor made of wooden beams

For beam ceilings, coniferous wood (spruce, pine, larch) with a moisture content of less than 14 percent is traditionally used. The best beam is a block with section proportions 7/5 (for example, 0.14x0.10 m).

IN dacha construction Floors made of wooden beams are especially common due to the simplicity and low cost of their construction.

When planning a wood-beam floor, it is necessary to use special diagrams that determine the correlation of beam sizes with the distance between supports and load; It is also permissible to proceed from the simplified calculation that the wide side of the beam should be approximately 1/24 of the length of the beam, and the thickness - 5÷10 cm, with intervals between beam boards of 50 - 100 cm and a load of 1.5 kPa.

If there is a shortage of lags of the design cross-section, it is permissible to use boards fastened with bolts, subject to mandatory observance of the total size.

Some features of installing wood beams:

The installation of beams is done in the following order: first the first and last, and then, with leveling according to the optical level, all the others. The beams should be placed on the wall structure no shorter than 150-200 mm.
The logs are moved away from the wall by at least 50 mm, and the distance between the beams and the smoke duct must be at least 0.40 m.
in wooden buildings, the ends of the logs are cut in the shape of a cone, and then driven into the cut of the upper crown to the full thickness of the wall log.
As a rule, in brick walls, the ends of the beams are installed in masonry nests in which condensation appears, therefore, between the cuts of the ends of the joists and the wall, space is left for air circulation, and if the opening is significant, an additional felt layer is placed.
To avoid molding that occurs when steam diffuses in the environment brick wall, the ends of the beam boards are cut with a slope of approximately 60 degrees, treated with an antiseptic (Tikkurila, Kartotsid, Dulux, Biofa, Pinotex, Tex, Cofadex, Biosept, KSD, Holzplast, Senezh, Teknos, Aquatex) and covered with roofing felt, leaving the end uncovered.

The attic floor is insulated by installing a vapor barrier layer under the insulation, the basement floor is thermally insulated by installing a vapor barrier film on top of the insulation layer, and the interfloor floor is not subject to insulation.

If the issue of the load capacity of wooden interfloor floors is mainly settled by the obvious increase in the cross-section of beams and their number, then with fire resistance and acoustic insulation the situation is somewhat more complicated.

One of the options for increasing the soundproof and fireproof performance of timber interlevel ceilings consists of the following steps:

To the bottom of the beam beams, perpendicular to them, with the help of elastic holders, after 30-40 cm, lathing bars are installed, onto which gypsum boards are attached from below.
A fiberglass film is spread onto the upper surface of the resulting lattice structure and stapled to the beams, onto which mineral fiber boards, such as: Isorok, Ursa, Isover, Knauf, Isomin, Rockwool, are tightly laid out, in a layer of 50 mm, with a transition to the side faces of the beams.
In the rooms of the next level, a layer of chipboard (16÷25 mm) is nailed onto the beams, after that, a hard mineral fiber sound absorber (25÷30 mm) is laid again chipboards"floating" floor.

Bitumen slate roofing

Soft slate (also known as ondulin slate, ondulin, euro slate, bituminized slate, bitumen slate) is essentially a molded cardboard-cellulose material, fixed with a distilled bitumen compound and colored with a polymer, ultraviolet-resistant, coloring composition. bitumen slate is made under various brands (Bituwell, Aqualine, Nuline, Onduline, Guttanit, Ondura, Corrubit). Usual dimensions of corrugated sheets: 2000x950, number of waves - 10.

The main qualities of bitumen slate roofing- speed of construction and affordable cost. In terms of weak points, it is worth mentioning the rather fleeting loss of richness of color, as well as the noticeable flammability of bitumen-cardboard material, compared to metal tiles.

The roofing material is laid on a solid base made of sheathing layer and rafter beams.

In the case of private buildings, a structure of two or three spans with intermediate supporting walls and inclined rafter beams is usually used.

The interval between the rafter legs is usually in the range of 0.60...0.90 m with width/thickness rafter legs 5x15...10x15 cm; the supporting ends of the rafter beams are fixed to a fixing beam measuring 100x100...150x150 mm.

The transverse overlap of the bitumen slate sheets and the frequency of laying the sheathing are determined by the slope of the roof slope: if the angle is more than 15 degrees, then the gap between the boards of the sheathing structure is set to 0.30...0.35 m, and the overlap is 17 centimeters.
It is better to fasten corrugated ondulin sheets from the lower zone of the side part of the slope, opposite to the leeward side, to protect them from wrapping under hurricane loads.
The next layer is laid with a shift halfway across the sheet, from the sheets of the underlying tier, in order to avoid unnecessary layering at the joints of four adjacent sheets, which contributes to the formation of leaks.
Euro slate sheets are fixed along the bottom edge to each wave crest, along two intermediate sheathing boards - to odd wave crests, and the top is covered with an overlap of the top sheet or a ridge piece. To secure each corrugated sheet, about twenty roofing self-tapping screws (size 65.0x5.5 mm) or nails: length/diameter -73.5/3.0 mm with elastomeric washers are enough.
It is enough to arrange the row overlap of the canvases in one wave, and when the roof slope is less than 10-11 degrees. - in 2 corrugated waves.
The ridge is strengthened from the side where the corrugated sheets are laid, with an overlap of 0.2 m, with screws being screwed into each corrugation vertex of the underlying corrugated sheet.
In order to protect and decorate the side sections of the roof slope, chip profiles are used, the fastening of which begins from the corner above the cornice, with an overlap of 0.2 m.

Having caught fire with the idea of their own home, the customer cannot always explain to the specialist what he wants. This happens especially often in case of refusal from standard projects offered by the company’s portfolio. Now the visualization problem is solved - the program comes to the rescue timber house, developed on the platform of 3D technologies, allowing you to look at the future creation long before its construction. Details about the service are below.

Electronic Help Features and Capabilities

A clear picture seen from all sides makes an impression. The ability to furnish a house or make changes to it before the construction of walls and other elements begins is the basis of a computer service that is accessible even to the user.

Electronic support for these purposes is varied. It is difficult to choose the best - everyone has some distinctive feature

. So, the programs for houses made of timber, presented below, have a common advantage - free download. More details about the functions of each:
VisiCon. Combining project and design. The user is given the opportunity to independently design the interior of a log house without outside help.

The latest options are intended for home use. They can change the appearance of a finished house, garden plot, etc.

Once the visualization has been decided, pressing questions arise - how much material will be needed, how to construct the object, the rafter system. Determine the required quantities - displacement, center of gravity, etc.

Then a special tool comes into play - a program for calculating timber for a house and designing. Mainly, such assistants create a platform for the production of wooden house kits, where each element receives its own place and marking to further facilitate assembly.

SEMA - a program for the design and calculation of timber houses

What is so special about this product? More details:

Determination along the axes of any size of walls, windows, doors. Indicating the center of gravity of each.
Layout of individual rooms.
Calculation of energy efficiency.
Corner connection data - the library contains such as " dovetail", "paw", "bowl".
Calculation of double elements for frame structures.
Automatic determination of the number of elements - a program for calculating a house made of timber.
Layout of the rafter system taking into account the selected roof. Optimal calculation of sheathing and layers of material.

The internal position will also not be left without attention - the SEMA program for calculating timber for a house offers the design of wooden stairs as an integral part of construction timber houses, above one floor. The tool will easily determine the width and position of the steps, and also indicate the exact position of the locking connections.

Self-calculation

What does the cost of design work consist of? This is a question every land owner asks. There are many factors. So:

Evaluation of an independent sketch or drawing. The owner first provides the specialist with a list of his preferences.
The area of the future object - a timber house.
Making an advance payment. Sometimes it can account for up to 50% of all design work.
Changes to the finished plan. Up to three times, it can be free. Further, up to 25% of the total project price.
Preparation of documentation - architectural and structural solutions, drawings, printouts of calculations, etc.

It is clear that buying a finished project is not a cheap pleasure. But if we assume that the electronic brain will calculate all the nuances, then it is justified. However, this does not stop owners who decide not to give their hard-earned money for what, in their opinion, they can do themselves.

Rows along the axes.
House kit cards.
Specifics of all elements.
Layout schemes for crowns.

This program is fundamentally different from calculations, where you need to enter data in columns and then get the result. As a rule, such services do not achieve accuracy. The “house planking” program helps to do this with minimal losses.

The owner who wants to do own house unique structure, it is worth knowing that independent “drawings” and sketches will not lead to the desired result if they are not prepared in accordance with the norms and rules established by the BTI services or others. Unlike independent work– programs for preparing the expected appearance take into account not only the client’s wishes, but also the specifics of the materials and construction area. The price for a finished and/or well-developed project is completely justified.

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

Our portal "Remontik" offers step by step steps calculating timber for building a house:

	Consumption of timber per house.
	Formula for calculating material consumption for load-bearing walls of a building.
	Material consumption for the roof frame of a house.
	Factors that influence the amount of materials needed for a roof frame.
	Calculation of the amount of material for sheathing and rafters.
	Number of blanks for constructing beams.
	Calculation of the number of floorboards.

Regardless of whether you are planning to build housing on your own or you decide to hire workers for this, you need to draw up an estimate. It will be the basis of all work.
A timber house contains the following structural elements:

walls;

roof;

floor and ceiling logs;

sheathing;

rafters;

fasteners and insulation;

windows and doors;

harness.

Consumption of timber for building a house

To build a house for permanent residence timber 150x150 mm, 150x100 mm, 200x200mm or 100x100 mm is used. Before starting work, it is worth choosing the size of the workpieces and calculating how much timber may be needed. Usually calculations are made in cubic meters, and not in pieces.

Calculation form for beams for load-bearing walls

Calculation of timber for building a house can be done using the following formula:

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

As a result, you will receive the number of cubes that you will need to build a house. As a rule, they are limited to one or two floors.

As a result, to build a house you will need 13.5 m 3 of timber with a cross-section of 150x150 mm. If you plan to use more walls, then it is important to take them into account in the calculations.

For the convenience of calculating the construction of a house made of timber and facilitating the choice, you can use the data given in the table (with a length of 6 meters):

Beam section	Pieces per cube	Volume of one piece
200x200 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 make the correct calculation for building a house from timber, you need to take into account what you cannot avoid during individual construction - even a trusted supplier will have several defective units in one batch. This must be taken into account when purchasing and order blanks with a small margin.

Material consumption for the roof frame

For a log house it is used rafter system, which stands load-bearing frame roofs. The tree is durable material, but despite this, it should not be overloaded, otherwise it can cause the destruction of load-bearing walls and uneven shrinkage.

The rafter system belongs to the category of pitched roofs. Cheaper and easier to build gable roof with your own hands. The technology is accessible to a beginner, and it requires much less material.

Factors affecting the amount of material needed for a roof frame

If you want your roof to be not just beautiful, but also reliable, do not skimp on building materials. It is important not to deviate from the technology when building it yourself.

The frame of a wooden roof contains the following required elements:

rafters or rafter legs;

pediment, consisting of timber, similar to load-bearing walls;

beams (logs) - horizontally located beams that provide the basis for laying the floorboard;

Mauerlat - a thick layer located around the perimeter of the walls, used to distribute the weight of the frame equally;

sheathing - attached to the rafters and serves as the basis for installing the roof.

How to calculate the cost of building a quality house made of timber

According to SNiP 31-02, any roof has a number of requirements, taking into account which you need to calculate Construction Materials. That is, in order for the frame to fully comply with the stated standards and protect the house from snow, rain and melt water, and not allow cold air to pass through, you need to find out exactly how many blanks are required.

Calculation of the amount of timber for the frame: Mauerlat

The amount of material directly depends on the coverage area. For example, we can consider a 6x6 house. For a high-quality foundation you will need a thick, strong beam 150x150 mm or 150x100 mm. It is laid on four load-bearing walls, respectively, to make a Mauerlat, you need four beams, each 6 meters long.

Attention! If the house does not require internal load-bearing walls, then it is important that the distance between them does not exceed 8 meters. If there is another support inside the house, then it is worth increasing the distance to 14-16 meters.

For example: 6+6+9+9=30 meters.

The perimeter, namely 30 meters, must be divided by the length of one bar: 30 m/6 m = 5 pieces.

As a result, to build a mauerlat for a 6x9 m house you need 5 bars of 6 meters each.

Calculation of the amount of material for sheathing and rafters

The rafter system is the main support for the roofing material, which protects the house from snow and wind.

Calculation of the timber that will be used for the construction of rafters is done using the following formula:

The total load of wind and snow per 1 m 2 of the roof - it is calculated on the basis of SNiP 2.01.07-85 “Loads and impacts”. Therefore, for a slope with an angle of 45 degrees, the length of the roof is 6.5 meters and the length of the rafters is 3.5 meters, the load is 226.3 kg/m2.
Total load – 5148 kg. Now we multiply 6.5 m by 3.5 m and get 22.75 m, which represents the surface area of the slope (5148 kg).
Then you need to find out the length of all the rafters and how much timber you need to purchase for their construction. For this, given that 1 linear meter can withstand a weight of 100 kg, divide 5148 kg into structures and get 51.48 m. This will be the minimum length of the rafters.
The roof slope overhangs the wall by approximately 50 cm, which means you need to buy 4 meters of wood.
It is very easy to calculate the number of pieces: 51.48/4 = 12.87, or more precisely 14, since they are arranged 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 is obtained if you divide the length of the roof by one less than the number of pairs of rafters, namely 6.5/6 = 1.08 meters. The cross-section of the workpieces is 150x150 mm or 100x150 mm.

The rafter system also contains wooden sheathing. For it, boards approximately 2.5 cm thick are used. They need to be positioned horizontally, namely parallel to the ridge.

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

The first is continuous styling, when the distance is no more than 1-2 cm and is sparse. In this case, the flight can reach 10 or more centimeters. The more often the boards are laid, the warmer and stronger the structure, but at the same time its cost increases.

Calculating the quantity is very simple. The length of the board and skate is measured. Then the installation of the skate must be divided by the footage of the board. This way you can find out how many boards are needed for the support strip.

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

Calculating the cost of building a log house is a painstaking task. Therefore, it is important to take into account that everything must be purchased in reserve. Roofing consumption is calculated taking into account the roof surface area. In this case, natural openings are not taken into account - space for the attic door and chimney door, if there is one in the project.

Beam floors are especially in demand in low-rise construction. They are characterized by a relatively low price, they are quick and easy to make, wood is a durable material and is light in weight. It does not place significant loads on the foundation structure.

For floor beams, only coniferous wood is used. In most cases, this is larch, since it is the most reliable and durable material that can withstand heavy weight:

good resistance to temperature changes;
stable tightness;
practically does not shrink.

Worth giving preference the best preparations, which were dried in steam chambers and have a humidity of no more than 14%. In this case, the aspect ratio should be 150x200 mm or 150x100 mm.

For proper design, in order to perform a competent calculation of materials for timber construction, you need to take into account the width of the span. The larger it is, the more often the beams are laid, and their number also increases. To cover an attic, it is not at all necessary to lay the pieces very close to each other.

We suggest that you familiarize yourself with the table, which allows you to determine how many pieces you will need:

Span width in meters	Distance between beams in meters	Optimal workpiece cross-section 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 span of 4 m you need to buy 6 blanks for laying floor beams, starting from a step of 1 m. That is, 4 pieces will be used to cover the span and 2 more will go to the edges near the walls. The cost directly depends on the length of the beam.

Calculation of the number of floorboards

Before calculating how much floorboard you will need, you should decide on its dimensions:

The optimal length is 4, 4.5 and 6 meters;
thickness is presented in the following sizes: 32 mm, 25 mm and 30 mm;
standard width – 105 mm or 100 mm.

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

The calculation of material for constructing a house from timber is carried out based on the width and length of the area to be covered and on how the board will be laid - across or lengthwise.

The calculations are quite simple. If you know the parameters of the workpieces, then you will determine the usable area; it is 5-7 mm less than the actual one as a result of the tongue and groove.

Manufacturers usually make boards 6 meters long. It is also necessary to take into account the amount of waste that you cannot avoid.

Calculations are performed as follows:

Divide the known area of the room by the area of the board, taking into account only the useful one - this is the amount required for installation.
When the room has parameters other than 6 meters, it is important to take into account the amount of intact material. To do this, the width of the room is divided by the working width of the floor board.

Based on the information received, you can easily find out how much it will cost you to build a house made of timber. At the same time, it is necessary to take into account such Consumables, as roofing material, insulation and additional fasteners. Their number directly depends on the area, house design and other factors.

Conclusion

Building a house made of timber will be much easier than a brick one, and is accessible to every novice owner. After completing the construction calculation, you will receive an approximate amount of the project, which you should focus on when planning your budget.

The beams are cut by specialists immediately to fit the finished construction project, where all the beams are adjusted to one another. The timber house construction calculator allows you to accurately calculate... The structure itself is erected from several days to a couple or three weeks, depending on the complexity of the project.

Material advantages

The timber is made from solid wood, which guarantees the structure high environmental friendliness and a minimum percentage of internal cracks. The shrinkage of a house made of timber is significantly less than that of other materials, for example, rounded logs.

Glued laminated timber is a very durable material, this is its undeniable advantage, since the house will not require any repair work or additional investments.

Choose timber from large manufacturers; the factories are very responsible in the production and storage of the material. Strict control of wood moisture content and the accuracy of pairing of nodes is what a large manufacturer guarantees and what will significantly speed up and facilitate the construction of a house.

The material is shipped in special transport packages, this protects the wood from environmental influences, humidity, precipitation and minor mechanical damage.

Well, practically the main argument when choosing is the final cost of the finished structure. Here timber also wins, compared to others, it is available to almost any consumer who plans to build a house for a long time from high-quality material.

The cost of the timber itself may turn out to be higher than planned, but here it is worth considering the entire project: due to the excellent thermal insulation of the timber itself, you can be more economical about it.

Structures made from timber are quite lightweight, which, in turn, allows you to work with a less expensive foundation. Taken together, these facts indicate that the market price for timber may seem high, but in the end the entire project costs less.

Among the additional costs when using timber, it will also be possible to exclude the cost of caulking: profiled timber does not need this, and there is no need to apply an antiseptic coating separately, the manufacturers will already take care of this.

House design and construction calculations

Before purchasing timber, make sure that you have a ready-made house project in hand. It is not necessary to order an expensive project for a new house; every construction organization will be able to offer you a choice of ready-made projects that this organization has implemented in the past.

It will be effective solution, since the builders will already have experience working on such a project and will be able to implement it in a short time and without force majeure. Also, each such project already has a calculator showing the required cubic capacity.

If you created the project yourself, or there is not complete, but partial construction - an extension or a terrace, then you can calculate the costs directly in the construction organization.

When planning to build on your own, you can use a resource called a log house construction calculator. By specifying the footage, the program will helpfully calculate the required material consumption.

Be sure to remember that a house is not only timber, it is also a foundation, interior decoration, and tools for assembling the structure. Boards for partitions, rafters, scaffolding. There are a lot of nuances in building a house, which is why it is better to entrust the work to professionals.

They are more likely to save your money than to spend too much. The percentage of defects among professionals will be several times lower, consumables are also used wisely: nevertheless, experience allows you to act more productively and faster than when building a house on your own. Besides, Building company is fully responsible for all stages of construction: from studying the soil under the foundation to covering the roofing material and interior finishing.

Quality determines cost

Summarizing all that has been said, it is worth noting several of the most important points. The cost of the house will be calculated based on the total production costs.

When choosing, consider not only the cost of one construction or finishing material, timber, for example, but also what kind of foundation this material requires, what kind of interior decoration, what the roof will be made of.

Only after this can we talk about the final cost of the structure and the benefits of this or that material. Be guided, first of all, by quality criteria.
