We offer a range of glazing options to ensure optimal thermal efficiency, weatherproofing, and sound insulation.
Our thermally broken aluminium frame incorporates two 27mm polyamide inserts, significantly reducing heat transfer.
Unlike cheaper alternatives that use a single aluminium frame, our system prevents heat loss and condensation, ensuring true thermal efficiency.
Our innovative frameless glazing system creates a seamless, ultra-modern appearance, making it an ideal choice for contemporary architecture.
This flush-glazed design also allows for both double and triple glazing while maintaining a sleek profile.
Opting for a triple glazed skylight enhances thermal performance and noise reduction, making it ideal for homes in urban areas or near busy roads.
Our flat glass rooflights typically achieve a centre-pane U-value of 1.0 but can be as low as 0.2 for exceptional energy efficiency.
Additionally, each flat glass rooflight is coated with a durable self-clean coating, allowing rainwater to remove dirt and grime, minimizing maintenance.

For roof access, we also offer 90-degree opening access skylights.
The FlatLight™ skylight features structural glass-to-glass jointing, creating an uninterrupted frameless finish.
Durable & Safe Toughened Glass
Our flat glass rooflights are made from heat-soaked toughened glass, which is up to five times stronger than standard annealed glass, ensuring maximum safety and longevity.
Our frameless flat roof skylights include a 48mm frame overhang, enhancing weathertightness and preventing leaks.
Simple Installation for Builders & Installers
Our frameless flat rooflight system is supplied with metal fixing straps for a quick and easy installation onto a 5° to 40° site-built upstand kerb, preventing water pooling.
Our flat rooflights are finished with a durable polyester powder coating to ensure long-lasting performance. We offer two standard RAL colours — Anthracite Grey (RAL 7016) and Black (RAL 9005).
For added flexibility, dual colour frames are available, allowing you to choose different internal and external finishes.
Every frameless flat rooflight is made to your exact specifications, ensuring the perfect fit for your project.
