In this article we will examine the issue regarding the construction of walls frame houses, or rather, its first stage - calculation and preparation of the necessary building material.
Necessary materials
To start building walls frame house you will need the following materials:
- Timber - it will be used to make vertical racks frame, as well as horizontal connecting jumpers.
- Edged board - it will be used for double-sided wall cladding.
- Insulation.
- Polyurethane foam.
- Roofing material - it will serve to waterproof the areas of contact between the embedded beam and the surface of the foundation.
- Fastening material (staples, nails, etc.).
Calculation
To calculate the required amount of building material required for the construction of the walls of a frame building, it is necessary to take the dimensions of the future building as a basis. All required sizes specified in your construction documents.
As an example for calculations, we will take the following parameters of the house as a basis:
- walls along the length of the house - 10m,
- wall height – 2.8m,
- the walls across the width of the house are 8m.
First, let's perform a calculation for the vertical load-bearing posts of a frame house. For this purpose, we need to calculate the total length of the walls of the building (10m + 10m + 8m + 8m), i.e. in our case, this value is 36m. Vertical wall posts are placed in increments of 50cm. However, the distance between the racks in areas where windows are located should be at least 1.2 m.
Based on the above parameters, we determine the required amount of timber for the vertical posts. We need approximately four cubic meters of timber, the cross-section of which is 100mm x 150mm.
In addition, for the base of the frame, the longitudinal connection, as well as the final connection, we will need about three more cubic meters timber of the same section. The result is seven cubic meters of timber.
To cover the walls of a building we need edged board with the following parameters:
- width – 150mm,
- thickness – 25mm,
- length – 3m.
For double-wall cladding, the number of boards is 4.65 cubic meters (in this approximate calculation we do not take into account doors and windows, since each owner has his own preferences regarding the number of window and door structures).
Insulation
Calculation of insulation intended for furnishing the walls of a house is carried out in different ways. Everything here is determined by what type of insulation you will use. In addition, the resulting calculation result is influenced by the thickness of the insulation, its dimensions. Knowing the parameters of the insulation of a frame house, these calculations can be easily performed independently.
well and next step There will be direct construction of the walls of your frame house. This is written in detail in our other article.
Frame construction in Lately is gaining great popularity. The cost of a frame house, compared to other materials, will be 30% less. It is very easy to obtain the consumption of lumber and facing mixtures. To calculate a frame house, an online calculator will be useful. The program works quickly. The main thing is to know the parameters and features of the future structure. Application features for obtaining reliable results will be discussed later in the article.
Project development
The first step is to develop a project for the future home. If you understand construction, you can compose it yourself. If not, seek help from an architect. The specialist, taking into account all your ideas and wishes, makes a drawing of the house.
The next stage is material selection and calculation required quantity and cost.
It is more convenient to make calculations at construction stages, which include:
- Pouring the foundation;
- Construction of the frame;
- Overlap;
- Roof installation;
- Roof.
An online calculator will help you calculate the construction of a frame house. It is important to remember that no two houses are alike. Therefore, it is worth paying attention to the location, presence and depth groundwater, type of soil, season of construction, and so on.
After selecting the concept and price, a detailed estimate is drawn up.
There are several technologies for building a frame house. Each geographic area has its own way of constructing a structure.
There is Scandinavian, Finnish, Canadian technology. Given their features, you should pay attention to some differences in design solutions.
The requirements directly depend on the materials that are used. After all, the reliability, strength and durability of the structure will depend on their quality and type.
Not only is it taken into account appearance, weight, resistance to loads and external influences are taken into account environment.
The designer must take their properties into account. Also pick up similar materials, which can replace the main ones.
Online calculations of the future frame structure
Calculating a frame house, if you use a calculator, will allow you to quickly find out the amount of material that is needed for future construction. Without the program, you may not buy more or take something extra, and this is an additional expense.
Almost everyone uses online payments construction companies, because it’s fast and convenient. Today, almost everyone can use the service.
Before use, it is necessary to determine the exact parameters and dimensions of the building.
To get a calculation, you must enter the values and click the “calculate” button. The exact amount will be displayed as a result after all calculations are completed.
Sometimes it happens that people have not yet decided on the exact project, but want to know the approximate cost. This option is also possible.
When drawing up estimates, it is necessary to take into account all the costs that will be required for materials and workers’ services.
If the construction of the structure is planned on your own, then the amount will be less than if workers are involved.
Types of online programs
Exist different types calculators for calculations. This allows you to calculate all types of materials for building a house.
Let's look at the most common types.
Heat loss calculation
The heat in the room depends on the temperature characteristics of the region where the structure is being built. Climate is not taken into account when a house is built for living in summer period time.
When calculating, it is necessary to take into account the coefficient of thermal resistance. This applies to walls, floors and attic space. If this is not taken into account, the cold will come from the floor or the heat will escape through the attic. As a result, you can get required thickness walls and ceilings. In most cases, frame houses are supplied in kits, which come with accompanying documentation.
Construction of a house using Canadian technology involves the use of sandwich panels. For exterior finishing A minimum amount of materials is required. Insulation is provided inside the sandwich panels.
Deflection of wooden beams
To design a structure, it is necessary to make a calculation bearing capacity beams Most often, single-span beams and beams are selected. This allows you to quickly obtain the result, taking into account the section, pitch and span length.
Construction Materials
Allows you to determine the size of the roof rafters, stairs, foundation, frame. And also their volume for construction, walls, foundation pits, pouring the foundation.
Roof area
Depending on the type of roof, it is required different quantities material for its construction. Carefully select the roof, taking into account the characteristics of the area, as well as its weight.
Metal tiles will be lighter than clay tiles.
Facing
For the exterior decoration of the house, lining is used, which imitates logs or beams. You must first calculate their volume.
Wallpaper and paints for interior decoration
The volume of paint that will be needed to cover the walls can also be quickly calculated. You must enter the surface area to be painted into the program. This way we will find out the average paint consumption and the number of layers. After entering all the values, we get the result. The value may be slightly different from reality.
When calculating wallpaper, you must enter its width and height, wall parameters, as well as the number of meters in one roll.
The program will display the estimated number of rolls.
conclusions
Construction of a frame house is an expensive process that consists of several stages. Initially, it is necessary to design the structure; it is better to resort to the help of architects. Next, calculate the amount of materials needed. Analyze and begin construction.

How much does it cost to build a frame house: calculate using an online calculator
To know exactly how much it costs to build a house in 2016, calculate the price for online calculator. This is a convenient aggregator designed to enter the necessary information and quickly obtain results.
What data should be entered into the frame house calculator?
Calculation on the frame house calculator is carried out without taking into account the cost installation work. The result is not exact, but as close as possible to final cost. Be prepared to enter the following data in special forms:
- Type of building: residential or country house, hangar, warehouse, other facility (select from the proposed menu);
- Number of floors (there is an option “one and an attic”, etc.);
- Width of the structure;
- Structure length;
- Floor height;
- Material for the construction of load-bearing (non-load-bearing) walls, partitions (in our case it is LSTK);
- Roof shape (single, gable, complex or hip).
Price includes required quantity frame elements, hardware for fastening and instructions for self-assembly.
How to save money on building a frame house in Moscow?
There is some compelling evidence that building a turnkey frame house is the most inexpensive type of construction. What you can save on:
- On the project: firstly, standard projects with sections of architectural and constructive solutions Ours are cheaper. Secondly, order a house kit from us and the project will cost you free. Minus 30-40 thousand rubles;
- On the foundation: the weight of the frame is distributed evenly over the entire area of the base and is about 37 kg per sq.m. Using a heavy foundation will lead to unnecessary expenses- here you can get by with light ones screw piles. Minus 2/3 of the cost concrete foundation ;
- When assembling the frame: hiring professionals for construction is more profitable because it eliminates non-compliance technological subtleties and reduces time to a minimum. The cost of installation is calculated at a rate of 2 thousand rubles. behind square meter the buildings. However, lightweight frame profiles can be assembled with your own hands, because the weight of even the largest part does not exceed 100 kg. This means you can still save on assembly. Minus 200 thousand rubles. (for a house of 100 sq.m.).
The amount will vary depending on the selected finishing materials (inside and outside), the complexity of the project, the presence (absence) of an attic or second floor, and the type of roof. Decide on the details, enter them into the calculator and get the final amount. You can also consult our specialists about the price by sending a request in the form feedback In chapter
Although building a house frame technology and is one of the cheapest options; its total cost can be several tens of thousands of dollars. Unlike a brick or concrete building, the construction of a frame building cannot be stretched over ten years, and most of the amount will need to be paid over two spring-autumn periods.
Therefore, before you finally choose a house project, you need to compare the estimate for this project with yours. financial capabilities. For an example of calculation, let's take a small 6x6 with an attic, being built in middle lane Russia.
How to calculate, what to take into account when calculating
The full cost of building a frame house includes:
- price of materials, components, fasteners, equipment, and their delivery;
- price of concrete and earthworks on the arrangement of the foundation;
- cost of carpenters' services for the construction of the frame and rafter system, installation of stairs, partitions, laying subfloors, outer skin walls;
- payment for roofers;
- cost of basic finishing works — internal lining walls and ceilings, insulation and insulation, finished flooring, installation of windows and doors;
- price for specialists installing heating systems, gas, water and electricity supply, ventilation, sewerage;
- price of decorative finishing.
As you can see, self-execution of all work will significantly reduce the necessary cash investments. The construction process can be distributed over 3-4 years as follows:
- Construction of the foundation.
- Carpentry and roofing works.
- Basic finishing work, installation of engineering systems.
- Decorative finishing.
When calculating, it is necessary to take into account the significant level of inflation in the country(behind Last year from 36 to 65 rubles per dollar), because the price of building materials rises quite quickly when the ruble exchange rate depreciates. It is better to carry out calculations in advance in dollars to avoid the common situation when the foundation built last year turns out to be too large and strong for the house for which there is enough money this year.
Calculation of the foundation of a frame house
In the construction of frame houses, two main types of foundations are used: — pile and tape. Pile foundations are more difficult to install, but are much easier to transport to remote areas. Longitudinal and transverse pitch It is customary to select piles in the range of 120-150 cm, based on the size of the building.
In places where the stove and stairs are installed, it is necessary to install an additional pile or a wider concrete base. The height of the strip foundation and the depth of screwing in the piles depends on the type of soil in the selected area; this can greatly affect the final cost.
General foundation work includes:
- Site cleaning from the soil to a depth of 30 cm with an extension of 0.5 m beyond the perimeter. Payment for work is about $10 per cubic meter of soil. For a 6x6 house - about $150.
- Laying the surface with geotextiles. 40 cents per square meter, $20 for a 6x6 foundation.
- Backfilling and compacting sand with a layer of 10 cm. Price - $25 per cubic meter of sand and $10 for labor, $150 and $60 in total.
Included in price pile foundation includes:
- Price of piles. 20-30 dollars for 1 piece. Total 600-900 dollars.
- Installation price— $15 for 1 piece, $450 total.
- The cost of a channel grillage. Depending on the thickness, the channel and its installation will cost 10-15 dollars per meter. For a 6x6 house you need at least 48 m of channel, a total of 500-750 dollars.
- Price for installing a plinth. A cast concrete plinth will cost $60 for the material, and the same for labor, given its length of 24 m.
The strip foundation estimate includes:
- Excavation. With a depth of 1 m, the price for a 6x6 house will be at least $150, taking into account the foundation along the external perimeter, and two transverse interior walls.
- Concrete works. Concrete and reinforcement will cost approximately $100 per cubic meter, installation work will cost $50. Casting a foundation 1 m deep, 36 m long, 20 cm thick will cost $700-1050.
- Waterproofing (roofing felt), embedded anchors, sewer pipes For groundwater- all together no more than $100.
In total, the foundation of a 6x6 frame structure will cost approximately:
- 1000$ when carrying out the work yourself, $1,700 when using a contractor - tape;
- 900$ and 1600$- cheap pile with caps;
- $1300 and $2100- durable pile with grillage.
Particularly worth mentioning is the need for formwork for strip foundations. The material used for the formwork must subsequently be applied to the hidden parts of the frame. Cost overruns if rejected can amount to $200-300.
House box calculation
The construction of the frame of the house must be done in one season in order to prevent prolonged wetting of the wood of the frame and subfloor.
Construction is carried out in several stages:
- Frame installation.
- Insulation of the subfloor and laying of subfloors.
- Installation of stairs.
- Installation of roof and gables.
- Covering the frame with waterproofing and OSB.
To calculate the cost of the frame, it is necessary to calculate the total volume of lumber and fastenings. The most common use of boards is 50x150 mm - it is used for crowns, trims, floor joists and vertical posts. The installation step of the racks and logs is 60 cm. IN longitudinal direction logs are installed less frequently, along the crown and foundation. Let's calculate the cost for a 6x6 house:
- Waterproofing the foundation with roofing felt in two layers— 24 sq.m., $10.
- Board 50x150x6000 mm— 7 pcs. for the crown, 16 pcs. to the bottom and top harness, 6 pcs. for longitudinal joists, 18 pcs. on cross beams. A total of 47 boards for about $5, a total of $240.
- Board 50x150x3000 mm— 44 pcs. for racks, price about $2.5 per piece. Total $110.
- Board 50x100x3000 mm- 18 pcs. on the racks of two internal load-bearing walls. Will cost about $30.
- 3rd grade board 30x150x3000 mm— 16 pcs. for jibs, $15.
- Beam 100x150x6000 mm- 2 pcs. for Mauerlat, $20.
For the formation of window and doorways scraps of 50x150 mm boards left over from cutting the rafters to size should be used (see below).
Underfloor insulation produced at will, it consists of filling the subfloor with expanded clay to the level of the logs. With a thickness of expanded clay of 30 cm, to insulate a 6x6 house you will need 10 cubic meters of expanded clay, which will cost $300.
Subfloor a log of 25x100 mm is installed in each cage cranial block 40x40 mm. Material consumption per cell is 60x150 cm, taking into account the thickness of the logs - 4 m of timber and 7.5 m of board. Total for two floors 6x6 - 320 m of timber and 600 m of board. When using grade 3 wood, the costs will be $40 and $120 for timber and boards, respectively.
Cost of stairs can really hit the budget of a demanding builder. Buying a carved factory staircase will cost $250 per meter or more. Manufacturing from purchased decorative materials It will come out 2-3 times cheaper, and from ordinary lumber with your own hands - about $25 per meter. The length of a two-flight staircase at an angle of 45 degrees will be about 5 m, a single-flight staircase - 4 m.
Attic and roof
- The gables are assembled like walls, and are installed at the ends of the roof. For two gables of a 6x6 house, equipped with a gable roof with a slope angle of 30 degrees, raised one meter above the ceiling to form an attic, you will need about 90 meters of 50x150 mm boards, for a total price of $75.
- The ridge beam is attached to the tops of the gables. If the length is more than 6 m, it must be supported by at least one supporting wall or support from a load-bearing beam. For the ridge, a double board with a cross section of 50x200 mm or more is used, for load-bearing beams - laminated veneer lumber. The price of a ridge for a 6x6 house is $15, with load-bearing beam from laminated veneer lumber 80x190 mm in the center - $55.
- The rafters are laid on the mauerlat and ridge in increments of 60 cm. A total of 22 are needed for 6x6 roof rafters rafter legs 4.5 meters long, made of 2nd grade board 50x150 mm. Total cost: $80. Considering that the material is sold by 6 m, the real cost will be $100.
- The roof is covered with wind and waterproofing. The price is about $40 per roll of 75 sq.m.
- Transverse lathing made of 50x50 timber in increments of 0.5 m will cost for gable roof with an area of 48 sq.m. for $25 (96 meters of timber).
- Costs for roofing material and additional parts depending on the selected material and roof intricacies can range from $6 to $12 per square foot. For example, the most simple roof without valleys, area 48 sq.m. The total cost will be $300.
External cladding -produced in two layers. First, the walls are sheathed with wind-waterproofing, then the structure is sheathed with OSB. All skins must be covered outer surface frame, including gables, as well as load-bearing walls on the side less exposed to moisture. The entire film is installed with an overlap of 10 cm. For a 6x6 house with a total area of external walls and gables of 96 sq.m and an area of internal load-bearing walls of 30 sq.m, the costs will be:
- 2 rolls of waterproofing for $40, total $80;
- 40 sheets of OSB 9x2500x1250 mm approximately, taking into account window and door openings, $12 per sheet, total $480.
There are two types of frame house partitions — load-bearing or non-load-bearing. The load-bearing ones are installed with racks on the crown, made of materials of large cross-section, using jibs and OSB for strength. Non-load-bearing ones can be made from 50x50 mm timber, covered with plywood or plasterboard. Their installation is possible at the stage of finishing work, on the surface of finished floors.
Price of fasteners(screws, corners, nails) to assemble a building box is 4-5 dollars per square meter of area, for a 6x6 building - 150-200 dollars.
Interim calculation of the cost of a house box
In total, a 6x6 house box protected from wind and rain will cost:
- 450$ - frame;
- 600$ - underground floor, subfloor and stairs;
- 600$ - roof and gables;
- 600$ - sheathing.
Most construction companies offer services for 30% of the price of materials, the total cost will be about $3,000. Having sewed up the openings with polyethylene, if necessary, such a structure can be left until the next construction season.
Windows and doors
The cost of windows including installation ranges from $50-100 per square meter, outer door— 100-300 dollars, interior doors- 50-100 dollars. For a frame house, it is undesirable to use windows wider than 120 cm, so as not to reduce the pitch of the racks by more than 2 times.
If for a 6x6 house we assume the presence of eight windows 120x120 cm (2 windows on each wall, except for the corner with the bathroom and shower, and one window on the pediment) and five internal doors, total costs will be at least $1000.
Insulation
Installing insulation is not very difficult; it is cheaper to do it yourself. Sheets of insulation are laid in the space between joists, posts, rafters and covered with a vapor barrier. The subfloor must be additionally covered with waterproofing before insulation.
Required layer of thermal insulation:
- For external walls and roofs- 15 cm or more.
- For load-bearing internal walls, floors and soundproofed partitions- 10-15 cm.
- For partitions- 5 cm or no insulation at all.
Most cheap material — glass wool, priced at $20 per cubic meter. But it is recommended to use a more expensive one in frame houses. basalt wool for $30, which has higher durability and environmental friendliness.
For a 6x6 house you will need for insulation:
- 1 roll of waterproofing — 40$;
- 4 rolls of vapor barrier — 80$;
- 21 cubic meters of mineral wool 15 cm thick — 630$;
- 7 cubic meters of mineral wool 10 cm thick — 210$.
In total, insulation will cost at least $950, or about $1,200 if you hire a contractor.
Installation of finished floors
Finished floors are laid along the rafters with boards 25x100-150 mm. If there are no plans to install a special flooring you can take a tongue and groove board. The price per square meter of flooring is $6 for a tongue and groove board, $4 for an edged board. Self-conducting work will save up to 50% of funds. Two finished 6x6 tongue and groove floors will cost $450.
Cost of communications and heating
- Costs for water supply and sewerage significantly depend on the distance from the water source and drain. Assuming that these points are in close proximity, the cost of the system is from polypropylene pipes, shower, bath, toilet, several sinks and taps, boiler will be at least $500, and $300 for the services of a specialist.
- Heating installation costs largely depend on the availability of the gas network and can exceed the price of the entire house. The cheapest installation is electric heating— $6 per 1 sq.m of heated area, but electricity costs will be huge. Water system heating from gas boiler for a 6x6 house will cost $1,300, as well as $1,000 for the services of specialists for installation and commissioning of equipment. The work of a good stove maker will cost 5-7 thousand dollars.
- When calculating installation costs power supply systems construction companies take into account the area of the house. An electrical system sufficient for normal living will cost 5-10 dollars per square meter of living space. Installing an electrical network in a 6x6 house will require costs of $250 for materials and $150 for specialist services.
Interior and exterior finishing
For interior decoration
Frame houses are most often covered with clapboard or plasterboard. average price for plasterboard is 3-5 times less than for lining, and is $4 per sheet with an area of 3 sq.m. It is better to sheathe some rooms with waterproof plywood (kitchen, toilet, shower).
For a 6x6 house you will approximately need:
- lining for finishing the attic - 80 sq.m., $400;
- plasterboard for finishing residential premises - 63 sq.m., $90;
- waterproof decorative plywood for finishing office premises - 63 sq.m., $200;
- floor and ceiling plinths - 96 linear meters, $400.
The total cost, including hired labor, will be $1600.
For exterior finishing
They use various types of siding, eurolining, block house or imitation timber. Different kinds materials can cost from 2 to 15 dollars per square meter. Quite presentable finishes can be found at prices starting from $5. Finishing a 6x6 house with Class A aspen clapboard will cost $500, and $400 in workers' compensation.
Additional finishing depends only on the imagination and budget of the owner, and is not included in the construction estimate.
Houses made of SIP panels
The technology for the rapid construction of houses from SIP panels, developed in Canada, allows you to speed up the assembly of the house and eliminate the need for insulation and waterproofing. The SIP panel consists of 2 OSB-3 boards, firmly glued to a sheet of especially durable polystyrene foam, size 1250x2500 or 1250x2800 mm.
The panels are fastened together by double inserts made of 40x200 mm timber, making up power frame buildings - floor joists, vertical posts. SIP panels are applicable as ceilings, walls, gables, rafters and continuous sheathing.
The cost of installing one slab will be:
- 40-70 dollars - panel;
- $10 – fasteners and lumber;
- $20 - work.
The total cost of erecting a 6x6 house box from SIP panels:
- $600 - roofing;
- $300 – subfloor insulation;
- $2000 - two floors;
- $3300 - internal, external load-bearing walls and gables;
- $1200 - rafter system.
Total including work $7400, with self-installation — 5700$. The initial investment will allow you to save on insulation and finished flooring in the future; in addition, according to manufacturers, houses made from SIP panels are much stronger than conventional frame panels.
TOTAL
As a conclusion, let’s summarize the cost of a 6x6 frame house for different options construction: Rating: 4.7 6 votes
Today frame construction more popular than ever. The fact is that calculating the cost of constructing the same panel house shows: the cost of such a structure will be at least 30% less than the cost of a similar house made of any other material. Calculating the consumption of lumber and the cost of cladding for a frame house is not so difficult. This will be discussed in the article.
Selection of materials and their influence on the calculation
It goes without saying that ready materials frame construction will occupy the largest share in the total estimate. Their expenditure will constitute a significant part of the budget allocated for construction.
First of all, attention should be paid to the consumption of lumber. In particular, the following materials will be needed for a panel house:
- Beam of various sections;
- Edged board with a cross-section of at least 5 centimeters;
- Edged board with a cross section of 2 centimeters;
- Tongue and groove boards with a section of 2.5 centimeters.
An example of calculating the amount of timber for a frame house in the design documentation
Calculating the cost of cross and rack beams is not so simple: here it is necessary to take into account the size of the future structure (its area), as well as the thermal insulation material that will be used during construction.
Calculation of the roof structure of a panel house and the choice of roofing material will also affect the final cost of construction. However, calculating the amount of roofing material is not so difficult.
In addition to wood processing industry products, it is necessary to calculate the consumption of materials for the following:
When calculating the cost of post and cross beams, you need to take into account the size of the future house, as well as the type of insulation used.
By the way, calculations of materials for the structures described above should be performed only after the owner of the house has decided on the material of the house frames and roof. They make everything else “dance” too.
Of course, if a person is ready to spend money to create a safety margin at home, then the calculations need not be made so scrupulously, but frame houses are also built, most often, precisely because they are cheap.
Wall insulation scheme for a frame house Ambient temperature and its influence on the calculation
The warmth in the house will depend on the climatic features of the area where the house is being built. This is a well-known fact. The only time when the climate can be ignored is if it is being built country house, in which exclusively summer accommodation is planned.
Here, in order to calculate the quantity, you will definitely need a table indicating the thermal resistance coefficients various materials, and all the indicators must be calculated separately both for the walls of the building and for the roofing pie, otherwise all the heat will simply escape through the attic floors and there will be no use.
Based on such calculations, you can obtain the final required thickness of the walls and roofing pie, which will be sufficient to retain heat in the house (based on the thermal resistance coefficient, again).
Layout of racks in a frame wall Also, it is much easier to make calculations if you know in advance all the parameters of the materials (for example, the weight of all structures) that the manufacturer has installed.
Usually, frame houses are supplied as house kits, so it will not be difficult to find out all these values (usually all this is indicated in the documents that necessarily come with the house kit itself).
It is interesting that if a house is built using Canadian technology, from sandwich panels, then a minimum of materials for its finishing will be needed. The fact is that insulation is already installed in such panels in advance, that is, they have a heat-insulating layer.
Device ventilation gap will require additional costs Most often, manufacturers as thermal insulation material sandwich panels are used specifically mineral wool. It turns out that the outside of the house will not need to be insulated at all (which means that the cost item for external insulation and leave only the internal calculations).
Calculation of thermal resistance indicators must be carried out separately for both the walls of the building and the roof.
Calculation of individual building structures
It is clear that before building frame house with your own hands, first of all, you need to include in the estimate the cost of material for building the roof and foundation.
Wiring diagram frame house Insulation of a frame house, both internal and external, is also an extremely important event, except in cases where houses are built using Canadian technology, using pre-insulated sandwich panels.
The cost of insulating a frame house will be approximately up to 20% of the total estimate, provided that factory insulation was not used in the house kit, and up to 10% if it was used.
If you build a frame house with your own hands, then great importance there will also be a consumption of lumber, and not even so much for the walls, but specifically for the roof. The cost of the same attic beams can be almost half of the price of the entire frame of a panel house.
We have already discussed the calculation of lumber for the walls of a panel house, so attention should be paid to the roof. Of course, if you buy ready-made house kits, then there will be no difficulty: the manufacturer has calculated everything in advance.
But how much lumber is needed for a panel house and its cladding, provided that you are building a frame house with your own hands - this is much more difficult. The insulation of a frame house has already been discussed above.
Roof
When designing the roof of a house, it is necessary to take into account not only total weight and load attic floors and beams, but also the weight, characteristics of the roofing material itself.
An example of a cost estimate for the construction of a frame house Particular attention should also be paid to the roof structure, during the construction of which it is necessary to take into account the wind rose in a certain area (that is, from which side the wind will blow more often - that side will have a greater load). Materials for construction are also selected taking into account these criteria.
In fact, it's quite important criteria for selecting materials and calculating their costs. If you do not take into account the same wind rose, then the roof on one side can leak, become leaky, and roofing material without proper reinforcement and fastening can simply be blown away by a strong wind, not to mention hurricanes and other natural troubles.
Nuances that must be taken into account before starting the construction of the roof of a frame house:
- It is not recommended to install a high and sharp-angled roof on a house in an area where extremely strong winds prevail (otherwise, you will have to calculate the roof with a fairly large margin of safety, which will inevitably lead to a significant increase in the entire construction estimate);
- roof sheathing should be installed at more frequent intervals to increase the safety factor;
- for the rafter system it is necessary to choose a stronger beam (than roofing beam the thicker it is, the stronger it is, everything is extremely simple here);
- better to choose something tougher roof covering, since it will be stronger (slate instead of metal tiles or corrugated sheets, for example).
If there is frequent wind in the area strong winds, it is better to buy a more rigid roofing material such as slate.
Foundation
For frame panel buildings, lightweight types of foundations such as shallow strip (most often monolithic), pile or even columnar foundations are usually used. True, we must take into account the fact that columnar foundations are suitable only for small frame houses, for a summer house, for example.
General scheme frame house devices As for piles, the simplest option is screw foundations. To calculate the number of piles, it will be necessary to take into account the entire mass of the house and the load per square meter of area from the solid foundation.
It will be necessary to take into account the condition of the soil in the area that was allocated for the construction of the building. It is also necessary to take into account the heaving of the soil and the depth of groundwater.
For example, if the foundation piles are not buried deep enough, then during cold weather the foundation will simply lift the house, which will immediately lead to the appearance of cracks of various sizes and partial destruction of the frame structure.
After all, what mistake do people often make when building houses on their own? They calculate the foundation only by the weight of the house - that’s all. But this cannot be done, because it is necessary to take into account many other criteria that were outlined above. But it’s better to have specialized specialists do this - it will definitely be more reliable.
