The Envirolay membrane is a vital component when installing Envirotile roof tiles in both new build and re-roof projects. Suitable in both warm and cold roofs, as well as support and unsupported roofs, it is a type FR underlay and roof space ventilation is required at both high end and low lever.
The flame retardant woven glass fibre cloth and aluminium foil weave has a high nail tear resistance which makes it untearable 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.
