RoofGuard-SB is a lightweight, high performance underlay for pitched tiled and slated roofs, ventilated in accordance with BS 5534 Part 1: 1997. Installed in the same manner as conventional tile and slate underlays, RoofGuard-SB prevents the ingress of wind-blown dust, rain and snow into the roof void. The RoofGuard-SB membrane is completely waterproof, and correctly installed it will provide temporary weather protection, prior to the application of the main roof finishes. The lightweight fabric type construction makes it clean and easy to handle, and the high coverage roll size allows rapid installation.
RoofGuard-SB is a three-layer construction, comprising two UV stabilised, high tensile polypropylene fabric layers, fused together by a combination of heat and pressure, around an impervious polypropylene film. RoofGuard-SB is dark blue in colour this allows chalk markings to be easily seen, a preprinted grid pattern assists cutting and reduces wastage. Roofguard SB should be laid printed side up.
