Installing
All Rooflights, curbs and accessories must be stored on a flat dry surface under cover prior to fixing. Rooflights should be stored on edge, not stacked horizontally and protected from the rain. Rooflights should not at any time be left in direct sunlight until installation is complete. Heavy items should not be placed on top as this can lead to damage or distortion.
Drill and securely fix curb to roof aperture through the bottom flange, 100mm from each corner and at maximum 300mm centre’s. Use very large headed fixings (not supplied), type and size as dictated by site conditions. Upstand curbs should be fixed to a structural component (i.e. not fixed through insulation). The 150mm high curb should not be fitted below roof insulation. The 300mm high curb can be used with roof insulation up to 150mm thick (unvented) or up to 60mm thick (vented). If fitted with insulation in excess of the above recommendation a timber ground 75mm wide x required thickness should be provided around the roof aperture.
Evenly position rooflight on to the waterproofed upstand or frame. Securely fix the rooflight using security screws* supplied. For PVCu, GRP or timber no pilot drilling is required. Do not overtighten. Install anti burglar cap. Locate the coloured weather cap onto the black screwbolt body then press the coloured cap downwards very firmly to fully locate (when correctly located a distinctive click will be heard). * For fixing to existing upstands other than timber (e.g. Concrete) Use fixings with an appropriate plug (not supplied). However, because site conditions are clearly beyond our control, it is the contractors responsibility to ensure fixings give adequate hold to existing upstand. If in any doubt, contact your supplier.
