Transform your living space with the Rooflight Factory Flat Roof Skylight, expertly designed to combine strength, clarity, and exceptional energy efficiency. Perfect for modern British homes, this skylight enhances natural light flow while maintaining outstanding thermal insulation and safety performance.
Triple-Glazed Construction for Optimal Efficiency
Each Rooflight Factory skylight is built with precision using a triple-glazed configuration that ensures long-term durability, excellent insulation, and energy efficiency. The three glass layers work together to deliver superior performance and visual clarity:
- Top Glass Layer: 6 mm Planibel Clearlite / Thermally toughened glass BS EN 12150
- Middle Glass Layer: 6 mm iplus Thermally toughened glass with Low-E coating EN 12150
- Bottom Glass Layer: Stratobel Clearlite 44.2 / Laminated glass EN 14449
This advanced design achieves a U-value of 0.9 W/m²K and a G-value of 58%, offering outstanding insulation and light transmission. The Low-E coating reflects heat back into your home during colder months while minimising heat gain in warmer weather. The clear tint ensures bright, natural illumination, enhancing the comfort and ambience of any room.

Installation Guidance
To ensure a precise fit and long-lasting performance, follow the installation recommendations below:
- Dimensions: The top pane features a black border, increasing the external measurements by 200 mm in each direction.
- Opening Preparation: When cutting the roof opening, allow an additional 10 mm internally from upstand to upstand for correct installation. For example, a 600 x 900 mm unit requires a 610 x 910 mm internal opening.
- Upstand Construction: Construct the upstand using 2×1 or 2×2 inch timbers for structural stability.
- Foam Rope & Sealant: Apply foam rope along the internal supporting baton to balance weight and pressure. Use Dowsil 791 black silicone sealant to achieve a watertight seal. Avoid using acrylic sealants, as they are not compatible with this unit.
