The construction of modern designs requires a competent approach to the selection of building material. It should be durable, withstand various loads, have a natural origin and not too much weight. It is desirable that the cost is not very high. This characteristics are quite consistent with OSB-4 plates.
The main feature of the material is its strength, which is achieved due to the special structure. The basis of the production of wood waste industry. The main raw materials are chips of pine or aspen. The stove consists of several layers formed from large-sized chips, the length of which can reach 15 cm. Number of layers – 3 or 4, sometimes more. Sliver is pressed and glued with the help of a resin to which synthetic wax and boric acid add.
The originality of the material is the different orientation of the chips in its layers. For the outer layers, the longitudinal orientation of the chips is characteristic, for internal – transverse. Therefore, the material is called oriented chipboard. Through the use of modern technologies, the slab is homogeneous in composition in any direction.
There are no cracks, emptiness and chipsets in high-quality material.
According to some characteristics, the stove is similar to wood, OSB is not inferior to it in ease, strength, simplicity in processing. Treatment is obtained high quality, since there are no bitch and other defects inherent in the wood. At the same time, the product is distinguished by fireproof, it is not subject to rotation processes, it does not start mold, it’s not terrible insects.
The single standard defining the size of the plates is not. Parameters may vary from different manufacturers. Most often occurs size 2500×1250 mm, which is called the European standard size. Thickness ranges from 6 to 40 mm.
4 grade plates stand out. The classification takes into account the strength and moisture resistance.
The most expensive are OSB-4 plates, they are inherent in high density and strength, increased moisture resistance.
The essential disadvantage of OSB materials is the use of phenol-containing resins in their production. The allocation of its compounds into the environment has a malicious effect on human and animal health. Therefore, in the manufacture of furniture and finishing of the premises, it is necessary to apply an OSP intended for these works. In addition, when using the product for internal work, it is recommended to be insulated with finishing materials and coatings, arrange ventilation in rooms.
Modern manufacturers switch to the use of polymer resins without formaldehydides.
OSB-4 apply, as a rule, only for outdoor work, which reduces their potential hazard to a minimum.
Scope of application
The material is very widely used from the manufacture of containers and furniture and ending with the construction work of various complexity. It is suitable for the inner and external wall cladding, the creation of interroom partitions, installation of floor flooring and alignment of floors, made the basis for roofing materials. OSB is well combined with both metal and wooden structural elements.
Increased density and strength, as well as additional processing allow you to build the bearing elements, walls and roofs from OSB. Due to the high mechanical characteristics of the material, frame houses and housekeeping can be built. In view of the excellent level of moisture resistance, builders recommend OSB-4 for structures with small roofing skes, in conditions of systematic wetting of the facade and the absence of a water supply system.
Tips for mounting
So that the constructable design of OSP-slabs served for a long time, it is important to avoid some errors when installing. Therefore, it will not be superfluous to listen to the advice of professionals.
Plates can be mounted horizontally and vertically – it will depend on their size and type of facilities. However, with any way it is necessary to make gaps in 3-4 mm.
Another important condition is to move the shelves of sheets in each next row.
Making an external installation of plates, for their mounting it is better to give preference to nails, as the self-tapping screws are often broken due to the severity of the material. The length of the nails should exceed the stove thickness of at least 2.5 times.
