Designed to be installed on roofs with a maximum pitch of 45 degrees, it ensures both durability and peace of mind for residential and commercial projects alike. Installation Recommendations Internal Dimensions: The top glass pane includes a black border that extends the external dimensions by 200 mm in each direction. Creating the Opening: Allow an additional 10 mm internally from upstand to upstand for a precise 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 a stable, accurate fit. Foam Rope and Sealant: Use foam rope on top of the supporting baton to distribute the load evenly and reduce stress on the glass. Apply Dowsil 791 black sealant for a watertight finish—avoid acrylic sealants. Flashing: Ensure the entire skylight perimeter is properly flashed. Each roll (7.5 metres) covers up to 6 linear metres—sufficient for skylights up to 1000 x 2000 mm. Perfect for Compact Spaces The 300 x 300 mm skylight is ideal for smaller installations where space is limited but natural light is desired. Whether fitted in a bathroom, stairwell, or loft conversion, it provides a stylish and efficient way to introduce daylight while maintaining insulation and weather resistance.
