Does window film work on double glazing?

Many films are suitable for double glazing, but not all. Film type, glass type and the age of the unit all matter, which is why we check compatibility at survey before recommending anything.

Will window film damage double glazing?

When a compatible film is chosen for the glass type, the risk is low. Choosing the wrong film for some glazing can cause thermal stress, which is exactly why we assess the glass before installation.
