Advanced Triple-Glazed Construction
Every Rooflight Factory skylight is engineered with three layers of high-quality glass, ensuring strength, safety, and optimal 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 advanced glazing structure achieves a U-value of 0.9 W/m²K and a G-value of 58%, offering superb thermal efficiency and light transmission. The Low-E coating helps retain warmth in winter and reduces solar gain in summer, ensuring a comfortable indoor environment. The clear tint and UV protection maintain clarity while safeguarding furnishings from fading.

Installation Guidance
For the best results, follow these expert installation recommendations:
- Dimensions: The top glass pane features a black border that increases the overall external dimensions by 200 mm in each direction.
- Opening Preparation: Allow an extra 10 mm internally from upstand to upstand for proper fitting. For example, a 600 x 900 mm unit requires a 610 x 910 mm opening.
- Upstand Construction: Build the upstand (the timber framework) using 2×1 or 2×2 inch timbers for a secure base.
- Foam Rope and Sealant: Apply foam rope on top of the internal support baton to distribute weight evenly and reduce stress. Use Dowsil 791 black silicone sealant to form a watertight seal. Acrylic sealants are not suitable for use with this product.
