Brightside Skylights Flat Glass Fixed Rooflight

Premium Made to Order Flat Glass Rooflight for Modern Homes and Commercial Buildings

The Brightside Skylights Flat Glass Fixed Rooflight is a premium, made to order flat roof skylight that combines contemporary styling with outstanding thermal efficiency, security and weather resistance. Manufactured in the UK using a robust powder coated grey aluminium frame, it offers an architectural finish without compromising on strength or long-term durability.

Ideal for home extensions, kitchen renovations, flat roof extensions, orangeries, commercial buildings and new build projects, this fixed rooflight floods interiors with natural daylight while delivering excellent energy performance. Available in a wide range of standard sizes with a typical lead time of just 3 to 5 working days, every rooflight complies with current UK Building Regulations, including Part L.

Contemporary Slimline Design

The Brightside Flat Glass Rooflight has been designed to maximise daylight while maintaining a sleek, minimalist appearance. Its slim aluminium frame is barely visible from inside the building, creating the sought after frameless look and uninterrupted views of the sky.

Finished in contemporary grey, the external frame blends seamlessly with modern roofing materials while providing outstanding structural support and weather protection.

Strong Aluminium Frame for Superior Strength and Security

Unlike many bonded frameless rooflights that rely solely on structural silicone, the Brightside Flat Glass Rooflight features a rigid aluminium frame that is mechanically fixed to the builder’s upstand for maximum strength and long-term reliability.

Enhanced Glass Protection

The aluminium frame protects the vulnerable edges of the glazing, reducing the risk of accidental damage during installation and throughout its service life.

Improved Security

Mechanically fixing the rooflight provides significantly greater resistance to forced entry than bonded frameless alternatives while also increasing structural rigidity.

Permanent Wind Resistance

Secure mechanical fixings ensure the rooflight remains firmly in position during severe weather conditions, providing complete confidence for years to come.

Advanced Weather Protection

The Brightside Flat Glass Rooflight incorporates an integrated aluminium drip edge and concealed water management system. Should the perimeter seal ever deteriorate after many years of service, any water is directed safely back onto the roof covering instead of into the building.

The rooflight is designed for installation onto a correctly constructed builder’s upstand with a minimum finished height of 150mm above roof level, helping ensure excellent weather performance and compliance with best practice installation guidance.

Outstanding Thermal Performance

The Brightside Flat Glass Rooflight delivers excellent insulation with an impressive centre pane U-value of just 1.19 W/m²K. Its advanced double glazed construction helps retain warmth during winter while reducing solar heat gain during summer, improving comfort and reducing heating costs.

  • Overall glazing thickness: 28mm
  • Centre pane U-value: 1.19 W/m²K

Quick and Straightforward Installation

The Brightside Flat Glass Rooflight has been designed for simple installation onto a weathered builder’s upstand. The unit is lowered into position and securely fixed using the supplied fixings through factory prepared fixing holes, removing the need to rely solely on structural silicone.

The rooflight is suitable for installation on roof pitches from 5° (1:11.5 fall) upwards and is designed to sit on a 75mm wide builder’s upstand. For optimum weather resistance, the upstand should extend at least 150mm above the finished roof level.

Manufactured in the UK

Every Brightside Flat Glass Rooflight is manufactured in the UK to exacting standards using premium materials. Each rooflight is made to order, ensuring excellent quality, precise manufacturing and long-term performance. Every unit is backed by a comprehensive 10 year manufacturer’s warranty.
