2 Step One Prepare a timber upstand for your rooflight Prepare a 75mm width timber upstand for your rooflight, this should be a minimum of 25mm in height from the finished roof level. The internal dimensions of your upstand should match the internal dimensions of your rooflight. Your hinged opening roof window needs to be pitched at a minimum of 6 to allow water run-off. If your roof does not have this pitch, build the angle into your timber upstand. Timber Upstand Dimensions (mm) 75 W Min. 25mm L Dimensions L and W are the length and width of your Fixed Flat Rooflight respectively. The internal dimensions are equal to the size ordered.

3 Step TWO Step THREE Step FOUR Apply silicone to your upstand Apply a bead of silicone around the top face of the upstand, as shown. The bead of silicone should be applied approximately 20mm from the internal edge. Position your Fixed Flat Rooflight Bring your Fixed Flat Rooflight into position. Align the rooflight so that it is centred on the aperture. Secure your rooflight to the upstand Use the recess in the rooflight s kerb to position the screws. Drill a pilot hole appropriate for your chosen screw diameter, and fix the frame with screws in the indicated positions: 100mm from each corner, and in the centre of the long sides. Page 3 of 6

4 Step FIVE A: Seal the unit with your roof s flashing Seal your flashing up the side of the rooflight, underneath the dedicated drip overhang. When using a torch to seal roof membrane, cut material to the suitable size, fold back and apply heat to the sheet away from the rooflight to avoid damage. Pre-heated membrane can then be bonded to the side of the rooflight and upstand. B: WHEN USING GRP ROOF FINISH When using GRP to finish roof, silicone bond a 4mm plywood border around the upstand and kerb, this will provide a more suitable surface for the GRP to adhere to. For plastering finish lines, please follow the cross section fitting, included at the end of this document. Congratulations! Your Fixed Flat Rooflight is now complete. 15 Dimension A is equal to the diameter of your O-Lite (for a 1000mm O-Lite, A = 1000mm) Page 4 of 6
