This skylight conforms fully to British Standards and Building Regulations and includes all required safety markings. It is CE marked, demonstrating compliance with EU directives for products sold across Europe. The skylight is suitable for installation at roof pitches of up to 45 degrees, ensuring flexibility and reliability in a range of architectural designs. Installation Recommendations Internal Dimensions: The top glass pane features a black border, extending the external size by approximately 200 mm in each direction. Creating the Opening: Allow an additional 10 mm internally (from upstand to upstand) to achieve the correct fit. For example, a 600 x 900 mm skylight requires an opening of 610 x 910 mm. Upstand Construction: Construct the upstand using 2×1 or 2×2-inch timber for stable support and a precise fit. Foam Rope & Sealant: Apply foam rope above the internal supporting baton to evenly distribute weight and prevent stress on the glass. Use Dowsil 791 black sealant to create a watertight seal around the upstand. Avoid using acrylic sealants, which are not compatible with this product. Flashing: The flashing must cover the full perimeter of the skylight. Flashing rolls are supplied in 7.5-metre lengths—sufficient for units with a total circumference of up to approximately 6 metres (e.g. a 1000 x 2000 mm skylight). Customisation Options Every roof is unique, and Rooflight Factory offers convenient custom-size skylight calculators for both standard and oversized frameless designs. This ensures a perfect fit and finish, no matter your project requirements. Why Choose Rooflight Factory?
