Norbord is the world’s largest manufacturer of OSB and has invested £145m in a new plant in Inverness, Scotland.
A new family of products is a development of the most popular OSB brand in the building and interior design arena and comprises SterlingOSB Zero 3, SterlingOSB Zero Tongue and Groove, SterlingOSB Zero SiteCoat, SterlingOSB Zero Fire Solutions and SterlingOSB Zero StrongFix.
It is a precision-engineered OSB3 board for structural use in load-bearing and challenging conditions; as well as being hugely popular in the aesthetics-led interior design industry. BBA approved and designed for humid conditions, it now 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 new 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. 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.
