OSB SMARTPLY (Oriented Strand Board)


SMARTPLY OSB is the smart and environmentally friendly alternative to imported plywood for use in the structural and non-structural applications. On-going product innovation continues to widen the scope of application of SMARTPLY OSB into timber frame and low energy construction.

All SMARTPLY OSB products have no formaldehyde added and are made using the most advanced manufacturing process in Europe. This process produces our flattest, straightest, most accurate boards, in the broadest range of sizes and thicknesses.
