Window film is fitted to double glazing every day. The key is choosing a film that suits the glass and checking any warranty terms first.
The short answer
Most double glazing can take window film. Choosing the right film for your glass, and the right side to fit it, keeps the risk low.
Why it matters
Some films absorb heat, which raises the temperature of the glass. On certain types of glazing this can add stress. We match the film to the glass to avoid this.
Warranties
Some window manufacturers have conditions about films. If your windows are still under warranty, check with the supplier before fitting. We're happy to help with the questions to ask.
