OSB

OSB stands for “Oriented Strand Board” and is made from thin veneer strands that are bonded together with a synthetic resin. BOLDERAJA OSB SUPERFINISH ECO consists of three cross-oriented layers with the surface of the board formed from strands oriented along the length of the board and the core strands arranged in cross orientation. This crosswise orientation of the individual layers achieves a high level of dimensional stability and an excellent mechanical performance.
Advantages

Multi-layered bonding provides exceptional dimensional stability and stiffness
High load bearing capability with high bending, compression and tension strength values
High racking resistance
Is easy to cut and fix using conventional woodworking tools
Can be coated with varnish or paint and may be glued with any adhesive recommended for wood
Can be custom manufactured to meet specific requirements in thickness and panel size
Advantageous thermal insulating properties when compared to similar construction materials
Formaldehyde emissions are ultra low, i.e. emission class E1
High durability
Delaminations and warping are virtually nonexistent
Natural wood surface finish provides an attractive appearance
A uniform structure with no knots or core voids
Remarkably smooth surface, consistent light and even
