Infinity provided the three framed fixed rooflights, free of charge, to Skill Builder to replace some old plastic skylights in a large wedding shop renovation. The team demonstrate how quickly the Infinity rooflights can be installed and fixed, once the 5 degree pitched up-stand is completed.
Skill Builder “Installing a framed flat rooflight is one of those jobs where the details matter. Get the kerb, pitch, and sealing right, and it’ll quietly do its job for years. Get them wrong, and you’ll be back fixing problems you thought were finished. This install uses an Infinity framed rooflight from TuffX, fitted to a pitched timber upstand and detailed in line with manufacturer guidance. We cover the practical considerations that affect performance on site, including upstand pitch, fixing methods, thermal performance, and sequencing. Infinity rooflights are manufactured in the UK and supplied as a complete unit, designed for flat and very low-pitch roofs. Standard double-glazed units achieve a centre-pane U-value of 1.2 W/m²K, with triple-glazed options available down to 0.7 W/m²K. Frames are thermally broken aluminium, supplied as standard in anthracite grey or black, with other RAL colours available.”
The Key Takeaways for Skill Builder were:
- Framed rooflights rely on the upstand more than anything else — the timber kerb must be built square, fully supported, and pitched at a minimum of 5° to shed water properly.
- Standard Infinity rooflights use double-glazed toughened safety glass with a centre-pane U-value of 1.2 W/m²K, with triple-glazed options available down to 0.7 W/m²K for higher-spec builds.
- The thermally broken aluminium frame reduces cold bridging and condensation risk, so performance is designed in rather than corrected on site.
- Two approved fixing methods are available — external fixing for fast weather-tightness, or internal fixing where access or sequencing demands it.
- Correct sealing is part of the system, not a last-minute fix — rely on proper detailing rather than excess silicon.
- Fixed rooflights are largely fit-and-forget once installed correctly, with no moving parts to adjust or maintain.
- Standard sizes are typically available within 3-5 working days, which makes programme planning more predictable on site.
- Long-term performance isn’t decided on install day — it’s determined by kerb design, pitch, and accuracy before the rooflight is ever lifted into place.
