Getting buildings wind and watertight is a priority on any construction site so choosing a quick, easy to install, reliable and versatile roofing system is vital.
High quality roof decking or pitched roof sarking is an essential component and Oriented Strand Board (OSB) is now the preferred option for many. Unsurprisingly, given the product’s outstanding attributes, West Fraser’s SterlingOSB Zero OSB3 or SterlingOSB Zero T&G are frequently the first choice.
Ideal for structural use in load bearing dry or humid conditions, SterlingOSB Zero OSB3 offers great value and durability. Stronger than most softwood ply, thanks to its makeup of multiple layers of real wood strands pressed together, it is designed to withstand the toughest of conditions. Working with the boards is trouble free as they are uniform in quality with no knots, voids or delamination issues. Helping to cut waste, a range of panel sizes and thicknesses is available to suit all needs.
The boards are square-edged so butt together easily and cleanly. Panels are cut and installed on a roof using conventional roofing equipment and are easy to saw, drill, nail or plane. Nails can be driven as close as 8mm from the panel edge without causing splitting. SterlingOSB Zero’s smooth surface gives improved adhesion qualities for all flat roofing applications and no sanding is required, even for GRP finishes.
With all the advantages of the Sterling OSB Zero range, SterlingOSB Zero T&G is specifically designed for flat roofing and is BBA approved and fully compliant to BS 6229:2003. The panels are consistent and machined to exact tolerances. Reliable fixings are easily achieved across the board using 3mm diameter ring-shank nails or 50mm long screws at 100mm centres across the supporting joists. The tongue and groove profile helps increase the lifespan of the roof by reducing movement of the boards, which could damage surface coverings.
Timber is a highly sustainable building product and, with the Sterling OSB Zero range, there is the added reassurance that the product’s environmental credentials are further enhanced. The panels are net carbon negative, responsibly sourced and FSC certified. They are manufactured in the UK from locally grown timber, cutting embodied carbon from transportation. In addition, all West Fraser mills have obtained the coveted environmental ISO 14001 accreditation. The Sterling OSB Zero range is also the first OSB product to be made in the UK with zero added formaldehyde, so it is an even greener board that meets all standards with ease.
