Sandtoft VPM Classic and Sandtoft VPM Super vapour permeable membranes can be used with all concrete and clay roof tiles and are suitable for both warm and cold roof designs on any roof shape and building.

They perform all the functions of good quality roof underlays and provide many benefits over the traditional bituminous underlays, helping to avoid condensation in the roof space.

Our membranes act as a secondary line of defence, protecting the internal roof substructure against wind driven rain and snow, safely draining it away to the gutter or other rainwater system. These underlays also reduce the wind loading on roof tiles and act as a temporary roof covering for up to a month prior to the installation of tiles or slates during building construction.
