What temperature can I apply film at?

It is safe to apply the film year-round. Gila recommends applying the film to cool glass, avoiding direct sunlight.* Note: Do not apply film when the outside temperature is below freezing (32 F.). Adhesive may crystallize if below freezing temperatures occur within the first three days of film application. For dual pane glass, because the inner pane is more shielded from the outside cold, the outside temperature should not be below 10-12°F to be assured that the application solution does not freeze before curing.
