The two companies have taken different approaches to producing FR OSB, with Norbord focusing on two options – an intumescent coating (No-Burn) for its Sterling OSB FR Coat and a non-combustible board bonded to its normal Sterling OSB for Sterling OSB FR Bond.
In contrast, SmartPly has made changes and investments to its Waterford OSB plant, with fire-retardants added to OSB strands during board production in the pre-press stage, giving a fire-retardant performance throughout the panel.
Both companies’ products have been listed in a recent update to a Structural Timber Association fire safety specification document.
