Facade decoration with OSB plates

OSB boards are 90% thin wood chips and 10% synthetic resins... The strength and reliability of the material is ensured by its structure. The mixture of shavings and resin forms a kind of layer, and the wood fibers in this layer are predominantly oriented in one direction. The OSB board includes 3-4 such layers - in terms of construction and properties it resembles plywood.

Release 4 types of material:

OSB-1 - designed for indoor use and is not resistant to moisture;
OSB-2 - durable and resistant to moisture, used for the construction of internal partitions;
OSB-3 - suitable for outdoor use, insensitive to moisture;
OSB-4 - heavy-duty version, used in the construction of load-bearing walls and roofs.

The moisture resistance of the material depends on the type of adhesive used, lamination or impregnation.

Pros and cons of OSB

Dimensional and shape stability

Large dimensions for easy installation

High sound and heat insulation with low thickness

Resistance to mold, decay

For interior work, it is not allowed to use material with an emission class below E1

The material is flammable, although it is prone to self-extinguishing

Cannot withstand a serious load

The service life is determined by weather conditions: the amount of precipitation and the frequency of frost.
