Description

Sterling OSB Type 3 board is a high-performance structural panel suitable for load-bearing flooring and roof decking in residential and commercial construction. The 18mm thickness provides adequate strength for platform floors and structural applications, whilst the tongue and groove edge profile ensures tight joints between boards and minimises waste during installation. Precision engineering eliminates knots, voids and delamination defects, delivering consistent panel quality across the board face.

Manufactured to Sterling OSB Zero specification, this board contains zero added formaldehyde, improving indoor air quality and environmental credentials. The panel performs reliably in humid conditions typical of house building and construction sites. BBA approval confirms structural suitability, and the net carbon negative manufacturing process means the board locks more carbon dioxide equivalent into the product than is released during production, supporting sustainable building practices.
