Frequently Asked Questions

Do Keylite Roof Windows come with a guarantee?
All Keylite Roof Windows are made with high-quality materials and workmanship, ensuring years of trouble-free enjoyment. All Keylite Roof Windows also come with a 10-year guarantee.
What size Roof Window do I need for my room?
To ensure enough natural daylighting, we suggest that the daylight area be at least 10% of the floor space. However, raising the ratio to roughly 20% improves the total impact significantly.
Are my Roof Windows secure from the outside?
Where the windows must comply with the security requirements of NHBC Standards, the opening lights can be installed with a key-operated locking system. Ultimately, it is the building designer's responsibility to identify where these standards must be met.
How much space in the roof do I need to leave for a standard Roof Window?
You must leave the window width + 20mm-40mm and the window length + 20mm-40mm. You must also install the top trimmer horizontally and the bottom trimmer vertically.
Why is my roof leaking?
99% of all leaky windows are due to improper installation. The six most frequent installation issues are: • C-Channels are installed incorrectly. • The hood and top apron are not properly joined (slate extension piece is missing). • The frame side flashing is not properly installed under the C-Channels. • The rubber end caps have been removed. • The flashings are not overlapped in the proper order. • The window was installed in a roof with a pitch less than 15°.
