Triple-Glazed Construction for Optimal Performance
The Rooflight Factory skylight is expertly engineered using three high-quality layers of glass, each contributing to the unit’s outstanding durability and energy-saving properties:
- 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 triple-glazed structure provides excellent insulation with a U-value of 0.9 W/m²K and a G-value of 58%. The Low-E coating helps regulate indoor temperature, while the clear tint ensures maximum daylight with minimal glare – creating a bright, energy-efficient environment throughout the year.

Safety and Compliance
At Rooflight Factory, safety is paramount. Each skylight is fully compliant with British Standards and Building Regulations, featuring all necessary Safety Markings.

Installation Recommendations
To ensure a perfect fit and long-lasting performance, follow these installation guidelines:
- Dimensions: The top glass pane includes a black border, extending external dimensions by 200 mm in each direction.
- Opening Preparation: Allow an additional 10 mm internally from upstand to upstand for precise fitting. For example, a 600 x 900 mm skylight requires a 610 x 910 mm opening.
- Upstand Construction: Construct the upstand using 2×1 or 2×2 inch timbers for optimal support and accuracy.
- Foam Rope & Sealant: Apply foam rope on the internal support baton to evenly distribute weight. Use Dowsil 791 black silicone sealant for a watertight finish. Avoid acrylic sealants, as they are incompatible with this product.
