7/16 phenolic poplar pine hardwood waterproof OSB board tongue and groove OSB

OSB is a material with favorable mechanical properties that make it particularly suitable for load-bearing applications in construction. It is now more popular than plywood, commanding 66% of the structural panel market. The most common uses are as sheathing in walls, flooring, and roof decking. For exterior wall applications, panels are available with a radiant-barrier layer laminated to one side; this eases installation and increases energy performance of the building envelope. OSB is also used in furniture production.

Five grades of OSB are defined in EN 300 in terms of their mechanical performance and relative resistance to moisture:

· OSB/0 – No added formaldehyde

· OSB/1 – General-purpose boards and boards for interior fitments (including furniture) for use in dry conditions

· OSB/2 – Load-bearing boards for use in dry conditions

· OSB/3 – Load-bearing boards for use in humid conditions

· OSB/4 – Heavy-duty load-bearing boards for use in humid conditions
