Compact yet stylish, this high-performance skylight combines cutting-edge glazing technology with a seamless frameless design, creating a modern, light-filled space that enhances both comfort and aesthetics. Frameless Design and Easy Installation Designed for a flawless finish, the Rooflight Factory Pitched Roof Skylight is completely frameless on both the interior and exterior, providing an uninterrupted view of the sky and maximising daylight. Its minimalist design complements any roofline, making it ideal for residential extensions, loft conversions, and modern refurbishments. Installation is straightforward, using lead flashing that can be cut on-site for compatibility with any pitched roof. Triple Glazed for Thermal Efficiency and Durability This non-opening skylight is triple glazed with 6 mm toughened, self-cleaning glass, delivering excellent energy performance and lasting clarity. With a U-value of 0.9 W/m²K, it significantly improves insulation, helping maintain an optimal indoor temperature all year round. The self-cleaning coating ensures minimal upkeep, as rainwater naturally washes away dirt and residue, keeping your glass spotless and bright.

Certified with the CE mark, this unit guarantees compliance with EU manufacturing and safety standards. Suitable for installations on roofs with a maximum pitch of 45 degrees, it offers both reliability and peace of mind for domestic and commercial projects. Installation Guidance Internal Dimensions: The top glass pane includes a black border that extends the external measurements by 200 mm in each direction. Creating the Opening: When constructing the opening, allow an additional 10 mm internally from upstand to upstand for a precise fit. For example, a 600 x 900 mm skylight should have a 610 x 910 mm opening. Upstand Construction: Build the upstand using 2×1 or 2×2-inch timber for strength and accuracy. Foam Rope and Sealant: For a perfect seal, apply foam rope above the supporting baton to distribute the weight evenly. Use Dowsil 791 black sealant to ensure a watertight finish—avoid acrylic sealants, which are not suitable for use with these units. Flashing: The full perimeter of the skylight must be properly flashed. Flashing rolls are available in 7.5-metre lengths; one roll covers up to 6 linear metres, suitable for skylights up to 1000 x 2000 mm in size.
