Norbord’s portfolio of OSB products is a development of the most popular brand in the building and interior design industries and comprises SterlingOSB Zero 3, SterlingOSB Zero Tongue and Groove, SterlingOSB Zero SiteCoat, SterlingOSB Zero Fire Solutions and SterlingOSB Zero StrongFix. They are variants of the precision-engineered OSB3 board; BBA approved and designed for humid conditions, it contains zero added formaldehyde and is unique in the market by being the only ZAF OSB manufactured in the UK.
Unlike traditional oriented strand board (OSB) containing urea-formaldehyde (UF) or melamine-urea-formaldehyde (MUF) binders, the SterlingOSB Zero family from Norbord uses a methylene diphenyl diisocyanate (poly-urethane MDI) resin to bind the thousands of strands that make up each board. SterlingOSB Zero is even more environmentally-friendly to produce than its predecessors. The pMDI binder cures at a lower temperature than UF/MUF resins so less heat energy is consumed during manufacture. It is also safer to produce since pMDI resin uses water as a catalyst in the curing process; UF/MUF resins need the addition of ammonium nitrate – an explosive chemical – to harden.
Like all Norbord OSB products, SterlingOSB Zero is made from forest thinnings taken from sustainably managed forests. All of Norbord’s production sites in Europe are able to produce wood-based materials that are certified according to the guidelines of the FSC or PEFC.
