Keylite Roof Window - Top Hung Fire Escape Hi-Therm - 1140 x 1180mm - White

The Hi-Therm technology significantly improves the window's thermal performance, indicated by a centre pane U-Value of 1.1 W/m2.K. This reduces heat loss, lowers energy bills, and enhances the comfort of your living space.

The window opens outwards, meaning the sash moves away from the internal space. This design maximizes the usable area within the room and ensures the opening is clear for emergency egress without internal obstruction.

This window is suitable for roof pitches ranging from a minimum of 15 degrees up to a maximum of 90 degrees.

The window is specifically engineered to provide compliant emergency egress. Its outward opening mechanism creates a clear escape route that meets regulatory requirements for fire safety.

The dimensions of this particular Keylite Roof Window are 1140mm in width and 1180mm in height (W 1140 x H 1180mm).

The window comes with an integrated, expanding thermal collar as standard, which helps to improve airtightness and thermal insulation.

The Keylite Roof Window is guaranteed for 10 years, providing long-term assurance of its quality and durability.

Check for any obstructions in the opening mechanism. Ensure the locking system is fully disengaged. If the issue persists, contact a professional installer as the mechanism may require adjustment.

Verify that the window is properly sealed and that the integrated thermal collar is correctly installed and expanded. Check the integrity of the external flashing and surrounding roof materials. Professional inspection may be required.

Some condensation is normal depending on internal humidity levels and external temperature. Ensure adequate ventilation within the room. If condensation appears between panes, it may indicate a seal failure and requires professional attention.
