Skyseal Aluminium Electric Opening Roof lights

Skyseal’s Flat Glass Electric Opening Roof Lights are a sleek and modern solution for natural lighting, designed for both residential and commercial buildings. Ideal for flat roof installations, these opening skylights bring daylight deep into your living space while improving ventilation and overall energy efficiency.

Available in a wide range of sizes and delivered within 5-6 working days, this glass rooflight offers excellent thermal performance and full Part L compliance. Whether you choose a manual option or the added convenience of electric opening roof lights, Skyseal delivers a high-quality roof light designed to perform all year round. 

Natural Light with Added Ventilation 

This flat glass opening rooflight opens up to 300mm, allowing fresh air to circulate freely throughout your living space. Designed to open and close easily, the rooflight is available with either manual controls or an electric roof light system.

Electric opening roof lights are ideal for hard-to-reach flat roof areas, offering smooth operation via remote control for effortless ventilation. Manual options remain a practical solution where the roof window is within easy reach.

Minimalist, Contemporary Design 

Featuring a slim aluminium frame, this roof light maximises natural lighting while maintaining a clean, architectural finish. From inside the room, the framework is barely visible, delivering uninterrupted sky views similar to those of a modern roof lantern, but with a flatter, more understated profile.

Each glass rooflight is low-maintenance and only requires occasional cleaning to keep it looking its best.

Strong Aluminium Frame Construction

The Skyseal flat roof range uses a highly developed aluminium frame to provide exceptional strength and rigidity (Read more here). Once installed, the frame minimises structural movement and offers enhanced support for the glass rooflight.

By protecting the glass at its most vulnerable points, the frame reduces the risk of impact damage. Tamper-proof fixings and high-grade silicone seals further improve security and durability.

Thermally Efficient Double Glazing

With a centre-pane U-value of 1.1 W/m²K, this electric roof light is among the most thermally efficient double-glazed roof windows on the market. High-performance double glazing helps retain warmth during colder months while reducing overheating in summer.

Glass specification:

  • 32.4mm overall (1.1 W/m²K)

  • 6mm toughened outer pane

  • 20mm 90% argon-filled cavity

  • 6.4mm laminated soft-coat Low-E inner pane

This advanced glazing combination supports excellent energy efficiency and long-term comfort.

Easy & Quick to Install on Flat Roofs

Skyseal’s electric opening roof lights can be installed on a minimum 2° fall, making them suitable for a wide range of flat roof projects. These roof lights provide a universal daylighting solution for extensions, kitchens, commercial spaces, and stairwells.

Install directly onto a prepared upstand or pair with a 150mm PVC kerb for a fast and straightforward installation process.

Questions & Answers (7)

How do I choose the correct size Glass skylight?

For glass units without upstand: Match your timber upstand's outside edge measurement to the skylight size (e.g., 900mm skylight needs 900mm upstand measurement). For glass units with UPVc upstand: Match the roof opening size exactly to the skylight size (e.g., 750mm skylight needs 750mm roof opening).

Which side will the hinges appear on the Rooflight?

The hinges will appear on the longest length of the rooflight.

Will the Skyseal Flat Glass roof light make my room cold?

The Skyseal Flat Glass uses a 24mm double glazed pane of glass which has a U-value of 1.1 W/m²K. The overall U-value of the skylight is 1.25 W/m²K. This should ensure that the heat stays in and the cold stays out.
