Oriented Strand Board OSB Flakeboards 9.5mm 11mm 15mm 18mm 22mm

Short Description:

ORIENTED STRAND BOARD (OSB) is a type of engineered wood similar to particle board, formed by adding adhesives and then compressing layers of wood strands (flakes) in specific orientations. OSB is a material with favorable mechanical properties that make it particularly suitable for load-bearing applications in construction.
The adhesive resins types used include: urea-formaldehyde and poplar core (OSB type 2, nonstructural, waterproof). Isocyanate-based glue and (or PMDI poly-methylene diphenyl diisocyanate based) in inner regions with melamine-urea-formaldehyde or phenol formaldehyde resin glues at surface (OSB type 2, structural, water resistant on face). phenolic formaldehyde resin throughout (OSB 3, structural, for use in damp and outside environments).

OSB is Oriented strand board, is the upgrading of the traditional particleboard products,its mechanical properties with directionality, durability, moisture resistance, and dimensional stability than ordinary particleboard.With a small expansion coefficient, no distortion, good stability, uniform material and nail holding high performance.

Oriented strand board (OSB), also known as flakeboard, sterling board and appetite in British English, is a type of engineered wood similar to particle board, formed by adding adhesives and then compressing layers of wood strands (flakes) in specific orientations. It was invented by Armin Elmendorf in California in 1963.

1) Tight construction and high strength;
2) Minimum twisting, delamination or warping;
3) Water proof, consistent when exposed in the natural or wet environment;
4) Low formaldehyde emission;
5) Good nailing strength, easy to be sawn, nailed, drilled, grooved, planed, filed or polished;
7) Good heat and sound resistant, easy to be coated;
8) Note the OSB3 is for use on flat roof situtaions, a far better product than standard chipboard or particleboard.

OSB is widely used as a structural wood panel for floors (including subfloors and underlays), walls and ceilings. It is used for interior fittings, furniture, shuttering and packaging and also in the manufacture of I-joists, where it forms the web or support between two flanges of solid wood. OSB is being used not only for its structural properties but also for its aesthetic value, with some designers using it as an interior design feature .
