The TuffX frameless flat rooflight combines high-performance glazing with a modern minimalist design, creating a clean external glass finish with no visible external frame. Manufactured using advanced glass-bonding technology, the unit offers excellent thermal efficiency, durability, and weather resistance — making it ideal for modern extensions, kitchen renovations, and flat-roof installations.

The frameless external design allows rainwater to run freely from the glass surface while maintaining a low-profile aesthetic that complements contemporary building styles. Internally, the slimline structure provides strong support while maximising the glazed viewing area.

Designed to meet modern thermal performance standards, this rooflight is a perfect upgrade or replacement for older skylights that no longer meet current insulation requirements.

The supplied insulated kerb simplifies installation and ensures correct positioning above roof level, helping achieve reliable weatherproofing and efficient drainage.

For optimal performance and water run-off, frameless rooflights should be installed with a minimum pitch.
