Safety & Compliance
At Rooflight Factory, safety and reliability are paramount. This product conforms to all relevant British Standards and Building Regulations and carries complete safety markings. It is CE marked, confirming compliance with EU directives for construction products. Suitable for roof pitches of up to 45 degrees, it offers versatility for various home and commercial applications.
Installation Guidance
- Internal Dimensions: The top 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 (upstand to upstand) to ensure an accurate fit. For example, a 600 x 900 mm unit requires a 610 x 910 mm opening.
- Upstand Construction: Build the upstand (wooden framework) using 2×1 or 2×2-inch timbers for a stable and secure foundation.
- Foam Rope & Sealant: Apply foam rope over the internal support baton to distribute weight evenly and reduce stress on the glass. Use Dowsil 791 black sealant to form a watertight perimeter. Acrylic sealants should not be used as they are incompatible.
- Flashing: Flashing must wrap around the entire upstand, sealing it to the roof tiles. Rolls come in 7.5-metre lengths — suitable for skylights up to approximately 6 metres in circumference (e.g. 1000 x 2000 mm units).
