Envirolay roofing underlay is the essential component for a full new build or re roof to ensure compliance with BS 476-3. It is a type HR underlay and roof space ventilation is required at both high and low level.
Envirolay is B.R.E. and Exova certified and is suitable for both warm and cold roof, supported and unsupported, ventilated roof constructions throughout the UK. The flame retardant woven glass fibre cloth and aluminium foil weave has a high nail tear resistance which makes it anti-tear in normal use. The thermal reflectivity of the material is designed to reduce the convection and radiant heat loss through the roof. In the summer months it reduces heat entering into the building, but also helps to maintain the heat in the building during the winter.
