Daltex® RoofTX®
DALTEX® RoofTX® is a 3-layer low resistance, vapour permeable air barrier roofing underlay, which resists the penetration of air into the structure. Daltex® RoofTX® Ultra is also certified for use in walling.
Daltex® RoofTX® is a low resistance vapour permeable air barrier roofing underlay, specifically designed to allow the ready transfer of moisture through the underlay, thereby reducing the risk of condensation in the roof structure. In warm pitched roofs and UK cold pitched roofs, when Daltex® RoofTX® is installed, there is no need to ventilate the roof space, providing the fabric is installed in accordance with the relevant Agrément Certificate, as the vapour permeability allows moisture to diffuse through the underlay. Daltex® RoofTX® is suitable for fully supported or unsupported roofing applications, and can also be used in conventional ventilated roof construction.
