With the demand for buildings to be greener and more efficient, timber is increasingly seen as a major construction material of the future. Timber is one of the most environmentally friendly building materials, offering superior insulation, low CO2 emissions and sustainability when compared to other options. 

In this section you will find BSI standards that cover the structural use of timber. These are essential reference for designers, manufacturers and construction workers; they cover timber frame walls, roofs, ceiling joists and binders, floor joists, rafters and purlins.
