Bring natural light and modern design into your home with the Rooflight Factory Flat Roof Skylight. Expertly engineered for durability and thermal performance, this skylight offers a perfect balance of energy efficiency, safety, and contemporary style – ideal for homes across the UK looking to enhance interior brightness and comfort.
Advanced Triple-Glazed Design
The Rooflight Factory Flat Roof Skylight features a precision-engineered triple-glazed construction, combining strength, clarity, and exceptional insulation. Each layer contributes to the skylight’s durability and energy performance:
- 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 high-performance glazing design delivers a U-value of 0.9 W/m²K and a G-value of 58%, offering superior insulation and excellent light transmission. The Low-E coating helps regulate indoor temperature by reflecting heat back into the room during colder months while reducing solar gain in summer. The clear tint ensures maximum daylight without compromising visual comfort.

Installation Recommendations
To ensure correct installation and long-lasting performance, please follow these professional guidelines:
- Dimensions: The top glass pane includes a black border, extending the external size by 200 mm in each direction.
- Opening Preparation: Allow an extra 10 mm internally from upstand to upstand for accurate fitting. For example, a 600 x 900 mm unit requires a 610 x 910 mm opening.
- Upstand Construction: Construct the upstand using 2×1 or 2×2 inch timbers for proper support and alignment.
- Foam Rope & Sealant: Apply foam rope on the internal supporting baton to balance the glass load evenly. Use Dowsil 791 black silicone sealant to achieve a watertight finish. Avoid using acrylic sealants, as they are not compatible with this product.
