Modern Frameless Design
The Rooflight Factory Pitched Roof Skylight is expertly engineered for a minimalist, seamless appearance. Its frameless design on both the interior and exterior creates an unobstructed view of the sky, giving your space a brighter, more open feel. Easy to install with on-site cut lead flashing, this skylight is compatible with all pitched roof types, ensuring a clean and weatherproof finish.
High-Performance Triple Glazing
Built to perform in all seasons, this non-opening skylight features triple-glazed, self-cleaning glass that combines strength, clarity, and energy efficiency. The self-cleaning coating helps reduce maintenance, while the Low-E layer and argon-filled cavities improve insulation. With a U-value of only 0.9 W/m²K, it ensures outstanding thermal performance — keeping your interiors warm in winter and cool in summer.

Safety and Compliance
Every Rooflight Factory skylight meets strict British Standards and Building Regulations to ensure long-lasting performance and peace of mind. Each unit carries the required safety markings and is CE marked, confirming full conformity with EU directives. Suitable for roof pitches up to 45 degrees, these skylights combine safety with sophisticated design.
Installation Recommendations
- Internal Dimensions: The top glass pane includes a black border, extending the external dimensions by 200 mm in each direction.
- Creating the Opening: Allow an extra 10 mm internally (upstand to upstand) for accurate fitting. For example, a 600 x 900 mm skylight should have a 610 x 910 mm opening.
- Upstand Construction: Use 2×1 or 2×2-inch timbers to build a strong and reliable upstand frame.
- Foam Rope & Sealant: Apply foam rope on top of the internal baton to balance weight and reduce stress on the glass. Seal using Dowsil 791 black-coloured sealant to ensure a watertight perimeter. Avoid using acrylic sealants, as they are not compatible with these units.
- Flashing: Proper flashing is essential to achieve a weatherproof seal. Each roll measures 7.5 metres, sufficient for one skylight with a total perimeter of up to 6 metres (e.g., a 1000 x 2000 mm skylight).
