OSB board - composite materialmodern production. Almost immediately after its appearance, it won leading positions in the construction industry. Such popularity is due to its high strength, regardless of the direction of the applied force. This material has absorbed all the advantages of natural wood, while it does not have its disadvantages.
Scheme of laying OSB floors.OSB boards are very often used during repair work, namely as a floor base. Anyone can do it themselves, the main thing is to follow certain recommendations and technology. Oriented strand board is an excellent option for making a floor base. It is worth noting that it can be used in any room. Ease of installation allows you to carry out the work as quickly as possible. In the finished form, the floor surface is perfectly flat. Any type of flooring can subsequently be laid on such a base.
Laying slabs on a concrete screed
When laying OSB boards on a concrete base,several different problems can be solved simultaneously. There are some peculiarities. Firstly, the sheet material can hide minor irregularities in the concrete floor, creating a smooth surface. Secondly, the sound and noise permeability of the floor is reduced and the thermal insulation of the room is significantly increased.
Installation of OSB boards on a concrete base.Wooden joists must be installed on the base if there are significant irregularities that need to be eliminated. If there are no such defects, OSB boards are laid directly on the floor. If the boards are to be laid on joists, it is necessary to use a material at least 8 mm thick, and it is recommended to make two layers. This will make the floor strong enough, and it will not sag when walking. In order to fix the boards to the beams, it is necessary to use ring nails. It is very important to ensure that the joints of the boards fall exactly in the middle of the bar. If the OSB is laid directly on the concrete screed, you can make one layer, for its fastening you can use an adhesive composition or fasten it with dowels. Important! When laying OSB sheets, it is necessary to leave a small gap of 3 mm between them. This is necessary so that the sheets can freely expand during acclimatization. Thus, the gap will not allow the sheets to deform. It is necessary to retreat a distance of 10 to 15 mm from the walls. In order to, it is recommended to first lay heat-insulating and vapor barrier material between the beams. It is very important that it is pressed tightly against the wooden bars. If gaps remain, they can form cold bridges. When starting to lay the slabs, it is recommended to impregnate the lower part with bitumen mastic. It is necessary to fasten the OSB with self-tapping screws, while it is also important to take into account the compensation gaps. The second layer must be laid perpendicular to the first. In order for the material to be stationary, a layer of glue can be applied between the layers. Return to the table of contents</a>
Laying OSB slabs on parquet and laminate
Installation of OSB boards on a wooden floor.Parquet must be laid on a flat and durable subfloor, such as a base made of OSB boards. OSB boards exceed regular plywood in technical qualities and can only be compared with FSF plywood, but they are much cheaper in price. There are some recommendations regarding installation work for laying parquet:
Roll coating is more sensitive todifferences in height and various defects of the base. Therefore, for laying linoleum, the surface must be sanded, and all gaps must be treated with high-quality sealant. Also, the heads of the screws should not protrude above the surface of the slabs, since they can damage the roll flooring. To glue the roll flooring, you can use special glue if the room is large enough, and double-sided tape if the room is small. With the help of OSB boards, you can very quickly and efficiently level the floors, prepare the base for laying decorative flooring. In order to do all the work yourself, it is worth preparing a minimum set of tools that almost every man has.
- a hacksaw on wood;
- grinding machine and sandpaper;
- self-tapping screws of suitable size;
- drill;
- screwdriver.
In order to achieve the desired result,It is necessary to apply the basic recommendations given by specialists. Such a floor will serve its owner for a long time, without requiring frequent repair work.
