Product Description

Ideal for brightening up new and existing flat roof extensions with natural daylight, the ECO+ fixed flat glass roof window is engineered with energy efficiency and user convenience at the forefront of design.

This is evidenced by all units coming with a low U-value of 1.1 W/m²K, which indicates outstanding thermal performance, and a pre-fitted, fully insulated PVC upstand to save customers time and money on building and fitting their own.

ECO+ rooflights are manufactured with a low-E coated, double glazed window unit filled with argon gas and a warm spacer. This stops heat loss through the roof, creating a comfortable indoor climate that is not over-reliant on heating.

The ECO+ glass specification is as follows: 6mm Toughened Outer Pane / 16mm Argon Filled Cavity / 8mm Laminated Inner Pane. 


The ECO+ maintenance free PVC frame is moisture resistant and therefore perfect for humid environments like kitchens and bathrooms, while the contemporary white internal finish fits all white-ceilinged rooms.

Keeping the exterior of the window clean is also easy thanks to the self-cleaning glass that comes as standard with every rooflight.


Safety is important factor of the ECO+ design. All units come with a toughened outer pane that will resist the impact of falling debris or any stray objects that might strike its surface.

Similarly, the inner pane has been laminated to keep it in place should it shatter, allowing you adequate time to find a replacement.


  • 10-year window guarantee
  • 20-year glazing guarantee
  • Lifetime hail damage guarantee


ECO+ flat roof blinds can be purchased alongside your electric rooflight to shut out or dim incoming sunlight. A crank opener will be needed to operate the blinds.

For warm room installations, consider the ECO+ 150mm extension kerb to achieve 300mm upstand height.
