Our Signature electric flatglass access hatches are double glazed as standard. Powered by two 24v actuators and a control panel, including a thermostat and rain sensor, these units can open up to 90° for excellent ventilation and ease of access to roof areas. The minimum kerb span for these units is 90cm.
The Signature flat glass rooflights all come with standard RAL colour slate grey. Alternative RAL colours can be selected when placing your order. For custom design finishes, please contact us on the number above.
We offer an easy clean glass upgrade for very little additional cost, and an obscure glazing option at no extra cost, at all!
For more information, please see our flat rooflight buying guide.

The Opaque Sandblasted Border
All of the rooflights in our Signature range come with a sandblasted border as standard. Not only does this hide the glazing frame, improving the aesthetics of these units, but it also helps to reduce the risk of thermal stresses and fractures in laminated glass, which in some cases can be increased by the use of a black-painted border.
Ritec ClearShield Eco-Glass™
Rooflights are always in hard to reach areas, and their position means that they can get very dirty. Sterlingbuild can offer a solution to this problem with Ritec's award-winning ClearShield Eco-Glass™ for flat roof windows. It has been specially developed for the renovation, protection and maintenance of both new and already installed glass.
ClearShield Eco-Glass™ is a “non-stick” glass, meaning your window stays cleaner for longer, resists all types of staining and discolouration, and keeps your glass looking like new.
Ritec's ClearShield Eco-Glass™ is very durable and can be easily reapplied over time, meaning your window requires a lot less cleaning.
