OSB

OSB is a relatively new building material of wood origin, which is designed for different types of work.Today produced 4 main and 3 special types of such panels.

method of manufacture of a plate OSB

Any OSB(from the English. oriented strand board) plate is produced from waste wood industry.OSB stands for "Oriented Strand Board (OSB)," and the basic material for her is wood shavings or chips.Usually used for manufacturing rectangular wood pieces that are glued together in layers.If you look at a photo OSB boards, we can note that the number of layers of wood chips may be three or four.

special uniqueness of such a plate is oriented fibers.If you look closely at the photo, one can note that all the outer layers are longitudinally oriented, and are perpendicular to the inner, ie across.Chips thus formed are pressed and glued by impregnation.It also uses a synthetic wax, resin and boric acid.These unique properties of OSB boards allow it to be more durable and strong.

Application

Due to the fact that there are no voids OSB, they are widely used in the construction industry.It used this building material for finishing both office and residential premises.These plates sheathed walls, is one roofing flooring, is used as the base floor surface.OSB is used not only to create a door, but also items of upholstered furniture.

Specifications OSB

If we take into account the technical characteristics of the OSB, all of them are divided into 4 main categories:

1. RSD-1 - chipboard with a low density of the material;They can only be used in areas with low humidity.In most cases, only be used for the manufacture of household items: furniture, wooden packaging, etc.
2. OSB-2 - having a higher density, so are used as load-bearing structures used in dry rooms.
3. OSB-3 - as shown by the reviews, is by far the most common and it is most often used to build walls, partitions, capital bearing structures.Such construction material can be used in areas having high humidity.
4. RSD-4 - very water-resistant plate which is used to work under heavy load.

no exaggeration to say that the properties of OSB boards simply unique.If you compare the specifications of OSB, we can see some difference between them.Classify the building material can be in thickness, which also affects the region of its application.Standard sheets of dimensions 2500 x 1250 mm, and the thickness may be from 6 to 26 mm.

Advantages Among the advantages of OSB can be called the following:

• relatively high strength (it all depends on the thickness of the plate);
• flexibility and ease that allows its use for covering curved surfaces;
• unlike plywood OSB does not separate;
• plate easily handled;
• has good sound insulation;
• not change their shape during operation;
• light weight (with a thickness of 9 mm sheet weighs only 18 kg).

Disadvantages

Sometimes talking about OSB drawbacks, the main of which is called - the use of these synthetic resins that contain phenol.Phenol really allocates carcinogens, but today manufacturers are trying to produce the building material without formaldehyde.Such OSB panels are denoted marking IVF.
