C-Thru Window Film has qualified film handlers to properly install your window film of choice. Window film is normally installed on the interior side of the window. However, exterior window films are available if an interior application would be impossible to access. The film is adhered directly to the glass by activating a water-based adhesive. There is no odor, or chemicals used. The surroundings are protected during the installation. Proper cleaning of the glass is an essential part of quality film installation. Once the glass is prepared the installer will precisely cut the film to the exact size of each piece of glass. When the release liner is removed from the film, the adhesive side of the film is applied to the inside surface of the glass with the aid of a mounting solution which is then squeegeed out. The film needs thirty days to cure properly. During this drying process there may be changes in the optical clarity. A hazy appearance may occur which is normal and will go away. Professionally installed films look better longer and are more likely to perform to specifications for their warranted lives, or even longer, than those improperly installed.
