High-Performance Triple-Glazed Design
Engineered for strength and insulation, every Rooflight Factory skylight consists of three precision glass layers that work together to provide superior clarity and comfort:
- Top Layer: 6 mm Planibel Clearlite / Thermally toughened glass BS EN 12150
- Middle Layer: 6 mm iplus Thermally toughened glass with Low-E coating EN 12150
- Bottom Layer: Stratobel Clearlite 44.2 / Laminated glass EN 14449
This advanced triple-glazed structure achieves a U-value of 0.9 W/m²K and a G-value of 58%, ensuring outstanding insulation while allowing generous natural light. The result is a brighter, more energy-efficient living space throughout the year.

Installation Guidelines
For optimal results and a precise fit, follow these installation recommendations:
- 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 a secure fit. For example, a 600 x 900 mm unit requires a 610 x 910 mm opening.
- Upstand Construction: Build using 2×1 or 2×2 inch timbers to ensure stability and support.
- Foam Rope & Sealant: Apply foam rope on the internal supporting baton to evenly distribute weight. Use Dowsil 791 black sealant for a watertight seal—avoid acrylic sealants as they are not compatible.
