Integrated Thermal Collar

Keylite has taken responsibility for thermally insulating around all of their roof windows, with a unique integrated Expanding Thermal Collar, included as standard on every roof window manufactured. Keylite’s “patented” expanding thermal collar is the only assured solution to address thermal performance in roof window installation.

Ventilation

Part F requirements for background ventilation are supported through Keylite’s cleverly designed top handle, allowing for controlled trickled ventilation when the window is fully closed and securely locked.

Flick-fit Brackets

The Flick-fit Brackets are pre-fitted, enabling the installer to get the window from the box to the roof in under 2 minutes.

Sash Finger Spring

This unique Keylite feature enables the installer to refit the sash into the frame in one smooth, easy motion.
