Installation Procedure | Film not for self-install - i.e., for professional installation. Pre-installation: film may not be recommended depending on factors such as glazing and frame types of existing window, presence of pre-existing film or certain coatings that reduce adhesion, presence of overhangs or other exterior shading. Film installation should not take place in very cold or dusty conditions. General installation procedure requires: cleaning of window and frame, cutting film to size, application of film to window (including multiple applications of water and detergent mix followed by squeegeeing), wiping dry. Post-installation: - Window not to be cleaned for a period of time, typically 30 days - Drying process takes weeks, during which small bubbles, haze, and other features may be visible; these should gradually resolve with time - It is normal for a 2-3 mm gap to be visible between the edge of the film and the gasket/frame For full details for any particular film product please consult with film installer prior to installation. |
Operation and Maintenance (O&M) Procedures | Window film should be washed with cleaning agent for windows or mixture of soap and water and wiped using a soft cloth or clean synthetic sponge. No bristle brushes, abrasive cleaning materials, or ammonia-based products are recommended. Paper towels may produce microscopic scratches that damage the film over time. |
