For example, a 600 x 900 mm skylight requires a 610 x 910 mm internal opening.Upstand Construction: Build the upstand (the supporting timber frame) using 2×1 or 2×2 inch timbers for stability and accuracy.Foam Rope and Sealant: Apply foam rope on top of the internal supporting baton to distribute glass weight evenly. Use Dowsil 791 black silicone sealant for a watertight perimeter. Acrylic sealants should not be used, as they are incompatible with the glazing materials.Customisation OptionsRooflight Factory offers a range of custom-sized frameless skylights and oversized frameless skylights to suit any architectural design or project specification, ensuring a perfect fit and seamless integration into your roof structure.Why Choose Rooflight Factory?Best Price Guarantee20-Year WarrantySecure Payment ProtectionSelf-Cleaning and UV Protected GlassClear Tint for Maximum Natural LightFree Delivery within London (M25)All Panels Safety Toughened and LaminatedMade in the EU with London-Based StockQuick and Easy InstallationStep-by-Step Installation Guide IncludedRooflight Factory Flat Roof Skylights combine cutting-edge glazing technology, energy efficiency, and elegant design.
