Using SterlingOSB Zero StrongFix in dry lining - Builders' Questions Answered

What are the benefits of wood panels behind plasterboard dry lining?
Plasterboard in itself is not suitable for bearing weight so, if the wall is intended for holding weight over 15kg such as TVs, sinks, cabinets, railings or similar, then a structural material such as wood panels should be used behind the plasterboard.

Why is OSB a better choice than plywood?
OSB is an engineered wood-based panel made from flakes of wood mixed with a resin and then pressed.  This method of manufacture means that the panel does not contain any defects of natural wood; for example knots or voids that plywood would contain.  This means that fixtures can be inserted anywhere on the panel without concern of hitting a weak spot. 

Is there a dry lining-specific OSB?
Yes.  Norbord manufactures SterlingOSB Zero StrongFix which is a panel designed specifically for metal C-stud dry lining at 600mm centres.  With a pre-cut groove, the panel is ready for installation right away – saving time and costs not having to cut to size.  SterlingOSB Zero StrongFix is made from OSB 3 and is suitable for structural use in conditions where some moisture is present.

What are the benefits of SterlingOSB Zero?
SterlingOSB Zero is an OSB panel made with zero-added formaldehyde.  This means that the board is smoother and more environmentally-friendly thanks to less emissions from the board.
