DALPRO ROOFING FELT - Breathable Sarking Membrane - 1.0 x 50 Metre Black/Gre
- SORRY, OUR SUPPLIER FOR THIS PRODUCT HAS CLOSED DOWN, & WE ARE TRYING TO FIND ANOTHER ONE -
DALTEX® Dalpro® is a 3-layer low resistance, vapour permeable air barrier roofing underslating felt, which resists the penetration of air into a roof structure. It is a semi-permeable polypropylene composite sarking felt, manufactured in the UK to the highest standards under the ISO 9001 quality system.
Daltex® Dalpro® Underlay Roofing Felt allows the ready transfer of moisture through the underlay as a breathable roof felt, thereby reducing the risk of condensation in roofs. In warm pitched roofs and UK cold pitched roofs, when Daltex® Dalpro® Roofing Felt is installed, there is no need to ventilate the roof space, providing the fabric is installed in accordance with the relevant Agrément Certificate instructions, as the vapour permeability allows moisture to diffuse through the underlay. Daltex® Dalpro® Roofing Felt is suitable for fully supported or unsupported roofing applications, and can also be used in conventional ventilated roof construction.
Daltex® Dalpro® Slaters Roofing Felt has optimum flammability resistance, complying with Class D of European Standard EN 11925-2. It is durable, flexible & lightweight allowing for easy installation, and offers temporary protection against wind driven rain, snow & dust, and can be used with slate or roof-tiles.
