Thickness of boobs

Thickness – this is the distance between the big surfaces (plastics) of the board. This parameter depends on the strength and maximum level of load to which the part is calculated. In addition, the thickness of the material, the more expensive. What thickness there are construction and finishing boards, and what parameters are considered the most optimal for various types of buildings.

Standard thickness

GOST 18288-87 Indicates that the board is a wooden billet with a thickness of up to 100 mm and a width of more thickness multiplied by 2. Materials with other proportions of sections or 10 cm thickness belong to other types: timber, bar, rail, plank.

General term for edged, unedged, planed blanks – construction board. Its standard thickness is determined by 2 GOST depending on the wood breed.

  • GOST 2695-83 for deciduous breeds assumes 12 gradations from 19 to 100 mm. It is 19, 22, 25, 32, 40, 45, 50, 60, 70, 80, 90 and 100 mm.
  • GOST 24454-80 For coniferous rocks sets 11 sizes from 16 to 100 mm. It is 16, 19, 22, 25, 32, 40, 44, 50, 60, 75 and 100 mm.

Thus, the minimum thickness of the construction board is 16, the maximum is 100 mm with a width of from 75 to 275 mm, length 2, 3, 4, 6 m.

Along with GOST it is allowed to apply industry standards or its own manufacturer standards. Therefore, Russian companies have developed their adopted line of sizes, which looks like this:

  • Edged board – 20, 25, 30, 32, 40, 50 mm;
  • Unedged board – 25, 40, 50 mm;
  • Planed board- 20, 35, 45 mm.

Edged, unedged, planed board is considered universal solver. For individual tasks, special types of boards are produced, for which there are their dimensional rules in millimeters:

  • Facade board, plaquene – from 15 to 25;
  • Floor board – from 21 to 40;
  • Parquet board – from 7 to 25, with gradations 7 (8), 10, 12, 15, 20, 22, and 25;
  • Terraced board and deck board (Decing) – from 22 to 40;
  • Lining on the European Standard (DIN 68126) – 12.5 (13), 16, 19;
  • The lining of domestic producers – from 12 to 40;
  • Block House (Imit Items) – 20, 22, 28, 30, 36, 40.

It should be noted that harsh standards (GOST) for most types of finishing boards are not, so on sale you can find materials and other sizes, for example, 14 mm.

Features of choice

To properly choose the thickness of the material, you need to take into account a few moments.

  • The higher the alleged load on the board, the greater should be its thickness. On stability, the type of board and the tree is also affected, from which it is made.
  • The thickness of the material may vary depending on the humidity. Therefore, if the raw material is purchased, you need to make calculations, considering the dermiska coefficient. And the material “breathes”, a little changing dimensions depending on the humidity of the ambient air. Therefore, you need to correctly fasten the boards, if necessary, leaving technical (temperature) gaps.
  • It is important to find nails or fasteners. General Rule: The nail is clogged to a depth of 3-4 times higher than the thickness of the part.
  • If the board before installing will be processed (rinsed, grinding), when you purchase, you must not forget to make the appropriate allowance.

For each type of structures there is its optimal material thickness. We give the most popular solutions for different types of work.

  • For the basics of frame houses 50-60 mm materials are most often used. For mounting overlaps, a single or twin board is used, put perpendicular to the floor plane. The thickness of the single board should not be less than 50 mm.
  • When installing the roof For the rafter, selected edged or planed boards with a size of 50 mm. For the crate, the thickness of the elements should be the greater, the greater the step between the rapid legs and the heavier coating materials for the roof. Under heavy materials (for example, cement-sand tile), 30-35 mm boards are usually used, under the lungs (for example, thin metal tile) – 20-30 mm. If you use a special board with stepped edges, then its thickness can be 4-5 mm less. This is especially important if it is planned to do cool roofing scat.
  • For external finishing at home Materials are selected, based on the designer idea. Standard thickness strongly depends on the selected style. But still, in the context of the Russian climate, it is not recommended to use for a warm house designed for year-round accommodation, cladding boards thinner than 20 mm.

The most popular materials are represented by certain sizes.

  • 20 mm – This size produces most of the t-shirt and unstipcled facade board (plaquen, lining, facade profile and other) domestic manufacturers. But if you wish, you can find options 24, 28, 30 and even 40 mm.
  • 21 mm – Gradually gaining popularity in Russia Scandinavian front panels (UYV, UYS, UYL, UYS), they are well suited to strip a house in Swedish or Finnish style.
  • An ordinary edged or grinding board 22 or 25 mm is the most affordable and at the same time the most universal version of the external facing. Allows you to create both monolithic and included ventilated facades.
  • Thickness 28 or 36 mm It is considered optimal to imitate logs, as it looks the most color. In addition, materials with such thickness are suitable not only for cladding, but also for the construction of walls at home. In this case, they are mounted in 2 rows, between which the thick layer of the heat insulator is located.

For finishing walls and ceiling of indoor rooms, a small or average panel thickness is suitable. Most often this is a 16.5 or 15 mm eurry, which is attached to the crate. A successful solution will also be the arrangement of the ceiling of plane or sexual 16-19 mm boards. For the stairs of the stairs inside the house, the material is used with a thickness of at least 1/20 march width (for a march width of 90 cm. The thickness of the stage is 45 mm). When arranging the stairs for the porch, the steps are best made from an anti-slip terrace board, the optimal will be the thickness of 27-35 mm. For the floor of the terrace, the verandas, the arbors also fit the deck boards of this thickness.

When setting the floor in the house it is important to choose the right to choose the thickness of the support lags. Usually make them from edged materials of coniferous breeds 50 mm thick. On top of the lags, the coating of the sexual or edged board of the next thickness is laid:

  • 20-25 mm – if between lags less than 50 cm;
  • from 30-35 mm – if between lags 50-70 cm.

Over the coating sometimes put parquet, using parquet, engineering or massive board. The minimum thickness can be 4-7 mm. But it must be borne in mind that the board is less than 10 mm is not intended for a cyclovka, and for a warm floor fit panels not thinner 12 mm. Usually choose 15 mm array – it can withstand several cycles and is suitable for a city apartment, at home and even for the office.

When building a bath, special attention should be paid to the trim and thermal insulation of the steam. The most fiscal option is a casing of 13-19 mm clapboard, but it sometimes begins to breed quickly. Therefore, more and more often, preference is given to Planken, which is largely similar to the clap, but significantly exceeds its water resistance. Paroon trim can be made of 12-25 mm building boards.

Wood ceiling steam room is exposed to the most extreme effects of hot steam and temperature drops, so the boards on the ceiling in the bath must be chosen especially carefully. It is recommended to use the material of coniferous rocks or from aspen, alder, linden, oak the next thickness (in millimeters):

  • for the flooring ceiling – from 50;
  • for stitched – 30-50;
  • for two-layer – 16-30;
  • for panel – from 12 to 18.

Pouring floor for washing and steam rooms usually make out of 40-50 mm edged board.

How to determine?

Information about the size of the board is necessarily indicated on the package. For materials made according to GOST, it is indicated by their type, cruise and breed of wood, dimensions, standard number. Nevertheless, when buying, it is necessary to make measurements to make sure that the wooden billet corresponds to the stated characteristics, in particular, the desired humidity level.

Unknown boards (this edged, unedged and plane board) may differ in size within the party, and if you need to sort it yourself, do it yourself. Therefore, when buying, you must have a roulette with you. The thickness of the sawn timber is determined by certain rules:

  • It is measured as a distance between two plastics;
  • Measurements are made by roulette, ruler or caliper;
  • Measures can be made anywhere in the material, but not closer to 15 cm from the edge;
  • The thickness of the umbered materials is measured without a bark.

According to GOST, permissible deviations from the nominal sizes in the thickness of the material should be no more than 1-3 mm.
