It can be used as an insulation layer in timber framed and masonry walls and as an underlayer in pitched roofs and flat roofs. In both cases battens are incorporated to maintain an unventilated air gap on both sides of the product. Supplementary insulation layers are usually incorporated to meet U Value targets in the building regulations.
