Are my windows suitable for window film?

We ask only 2 check are done before booking your fitting, check the glass size and glass type. 

Window glass size

To maintain quality and ensure every installation is achievable we require you check the size of the panes.

Pane definition – see the FAQ on what is a pane?

Glass type

The majority of homes in Norfolk have double-glazed uPVC windows or standard single-float panes – both of these are perfect for our window film.

However, to ensure the thermal properties of the film work safely with your glass, we cannot install film to:

  • Triple-glazed windows
  • Frosted or patterned glass
  • Georgian wired glass
  • Polycarbonate (plastic windows)

Applying film to these specific glass types can cause thermal stress or improper adhesion, which is why they are excluded from our standard booking service.

Do you doors also?

Yes we do, any clear glass double glazed door is perfect for our window film.
