Safety & Compliance
Every Rooflight Factory skylight meets the highest levels of safety and performance. This product is fully compliant with British Standards and Building Regulations, carrying all required safety markings. It is CE marked, confirming conformity with EU directives. Designed for reliability, the skylight can be safely installed on roofs with pitches up to 45 degrees.
Installation Recommendations
- Internal Dimensions: The top pane includes 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) for proper fitting. For example, a 600 x 900 mm skylight requires an opening of 610 x 910 mm.
- Upstand Construction: Build the upstand (the timber framework housing the skylight) using 2×1 or 2×2-inch timbers for strength and precision.
- Foam Rope & Sealant: Use foam rope on top of the internal baton to balance load distribution and relieve glass stress. Apply Dowsil 791 black sealant to create a watertight perimeter — avoid using acrylic sealants as they are incompatible.
- Flashing: Ensure flashing fully seals around the upstand and roof tiles. Each roll measures 7.5 metres, sufficient for up to 6 metres of skylight perimeter (e.g., 1000 x 2000 mm units).
