EWWS576 Boulder Developments Superfoil SF60
This is an assessment of Superfoil SF60, a multifoil type insulation product with a reflective vapour control layer for use in roofs and walls.
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.
