How to make a wooden floor in a house between floors in a house from aerated concrete or expanded clay concrete? Step-by-step instructions + Video and Photo How to make a wooden floor in a house? There are overlaps between floors in almost every building. They can be combined with concrete, wood and brick buildings. Structures are installed not only between floors, but also in basements and in attic rooms.

In such rooms one cannot do without overlaps, but the arrangement of overlaps in a wooden house between floors is somewhat different from those structures that are installed in the basement.

Features of wooden floors in the house

Such a construction for the most part includes only wooden elements.

But for finishing the ceiling and floor, any materials can be used. But when finishing the floor and ceiling, completely different materials are used, the most important thing is to correctly install the structure.

The main function of the ceiling is sound insulation. It is very easy to attach various insulating materials to a tree, including tile ones. From above, you can finish without any problems with any materials.

An important advantage of the structure is its low weight, since the floors are wooden. Such elements do not exert high pressure on the foundation of the building, and therefore they are often used for houses in which a light foundation.

If the installation was carried out according to all the rules, then this will contribute to the natural air exchange in the room. At the same time, the sound and thermal insulation of the rooms will not be disturbed. In general, wooden structures are quite strong, and make it possible to create durable and lightweight floors in a short time.

Technical requirements for floors

Interfloor wooden floors consist of the following elements:

  • Beams.
  • Plank layer.
  • Waterproofing film.
  • Sound and heat insulation layer.

  • Skirting boards.
  • Finishing board.
  • Ventilation slot.

For such elements and structures, there are the following requirements:

If the floors between which the overlaps are made, the difference in degrees is more than 10, then insulating materials should also be laid. This usually happens in the space between a residential building and a basement.

In this case, you cannot neglect the installation of thermal insulation.

  • Regardless of what type of wood is used, the beams in the structure must be strong. They should be so reliable as to withstand the overall load of the structure, people and the interior of the room. But besides this, there must also be an additional margin for the load. Remember that the minimum figure for a wooden floor in a house is 215 kg / m2 2 .

    For an attic floor in a wooden house, this figure is from 110 kg / m 2 .

  • For timber structures, the deflection factor should also be taken into account. It should be at least 0.4 cm per 1 m. The indicator can be calculated as follows - divide the length of the board by 250 and we get the deflection value max .

    We will make the same calculation for the coating on which the tiles are planned to be laid, but in this case it should be divided not by 250, but by 400. For attics, the divider is 200. this is taking into account sound insulation). Heat insulators can hide noise well. Sounds should not pass through communications and floors.

  • When calculating materials, consider the length of the timber beams. It should not be more than 5 meters, and for attics, not more than 6 meters. But constructions with a length of more than 6 meters are very rare. In this case, supports must be installed under the beams.

Attention! Wood is a highly flammable material, which is also susceptible to rot, bacteria and fungi.

For this reason, it is imperative to process the material before installation. The minimum requirements for impregnation are fire retardant and antiseptic.

Processing and installation

In order to make a wooden floor in a house between floors with your own hands, you need to figure out how it is arranged design. It consists of sheathing with sheet chip materials or a board and a beam frame. Mineral wool, glass wool or other similar insulators can be used as a sound-insulating and heat-insulating layer.

Sometimes you can use expanded clay or foam, but the first material will make the structure heavier, and the second is flammable.

For wooden interfloor floors in baths and saunas, it is very important to install waterproofing. In this case, vapor-permeable films that allow moisture to pass through only in one direction are ideal. Such material consists of expanding cones that absorb moisture only on the porous surface and does not appear on the other side.

Please note, that the vapor-permeable coating should be laid against the insulation with the porous side and "facing" the room.

When installing in a room, do the opposite.

Floor beams. In order to understand how to make a wooden floor with your own hands, you should understand the features of the structure frame. Wooden beams act as a basis here. Usually, elements are used that are 15 to 25 cm in height and 5 to 15 in thickness.

Between the beams, you need to make a distance of about 1 meter, it all depends on the section of the elements.

Important! The greater the load on the slab, the higher the beams' section should be.

In length, the support ends should be from 15 cm in length, and they should be laid in a "beacon" way. First, the extreme beams are installed, and after the intermediate ones. Use a level to check the evenness of the laying.

Resin pads made from leftovers can be used to level the joists.

Note, that sharp, hewn chips cannot be used to level the beams.

The beams must be laid with the same pitch and along the entire perimeter, parallel.Before laying, you should soak everything with an antiseptic and wrap it in 3 layers with roofing material. For block and brick buildings, floor beams should be coated with bitumen.

Thanks to this technique, you can protect the wood from moisture. For walls, the thickness of which is from 3 bricks, air vents should be left for ventilation, and at the junction of the wood to the wall, lay roofing material under the beams.


Now you know how to make a wooden floor with your own hands. Follow all the tips and tricks, and you can do everything quickly and efficiently.
