As a leader in both adhesive and film technologies, 3M brings together these disciplines to create the finest products available for both commercial and residential use. Our line of films provides an elegant means for solving many of the most challenging aspects of managing the energy use of your business or home.
Our films reduce up to 99.9 percent of the sun's ultraviolet rays and reject up to 79 percent of the solar heat that may otherwise come through a window, and can redirect daylight to increase occupant comfort, and overall energy efficiency. It also helps reduce winter heat loss by reflecting up to 17 percent of indoor heat back into the room. They are also easy on the eyes. On the outside, they give your home or business a more pleasing, unified look. On the inside, our films reduce the level of glare for you and others. 3M(tm) Sun Control and 3M(tm) Ultra Safety & Security Window Films not only save energy, they help protect your furnishings, drapes, carpet, woodwork and artwork from destructive ultraviolet rays that cause fading; help to seal out the water, the primary cause of property damage; and have a toughness that allows these films to withstand day-to-day abuse.

  1. EXECUTION

    1. EXAMINATION

      1. Film Examination:

        1. If preparation of glass surfaces is the responsibility of another installer, notify Architect in writing of deviations from manufacturer's recommended installation tolerances and conditions.

          1. Glass surfaces receiving new film should first be examined to verify that they are free from defects and imperfections, which will affect the final appearance.

        2. Do not proceed with installation until glass surfaces have been properly prepared and deviations from manufacturer's recommended tolerances are corrected. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result under the project conditions.

        3. Commencement of installation constitutes acceptance of conditions.

    2. PREPARATION

      1. Clean surfaces thoroughly prior to installation.

      2. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.

      3. Refer to Manufacturer's installation instructions for methods of preparation for Impact Protection Adhesive or Impact Protection Profile film attachment systems.

    3. INSTALLATION

      1. Film Installation, General:

        1. Install in accordance with manufacturer's instructions.

        2. Cut film edges neatly and square at a uniform distance of 1/8 inch (3 mm) to 1/16 inch (1.5 mm) of window sealant. Use new blade tips after 3 to 4 cuts.

        3. Spray the slip solution, composed of one capful of baby shampoo or dishwashing liquid to 1 gallon of water, on window glass and adhesive to facilitate proper positioning of film.

        4. Apply film to glass and lightly spray film with slip solution.

        5. Squeegee from top to bottom of window. Spray slip solution to film and squeegee a second time.

        6. Bump film edge with lint-free towel wrapped around edge of a 5-way tool.

        7. Upon completion of film application, allow 30 days for moisture from film installation to dry thoroughly, and to allow film to dry flat with no moisture dimples when viewed under normal viewing conditions.

        8. If completing an exterior application, check with the manufacturer as to whether edge sealing is required.

    4. CLEANING AND PROTECTION

      1. Remove left over material and debris from Work area. Use necessary means to protect film before, during, and after installation.

      2. Touch-up, repair or replace damaged products before Substantial Completion.

      3. After application of film, wash film using common window cleaning solutions, including ammonia solutions, 30 days after application. Do not use abrasive type cleaning agents and bristle brushes to avoid scratching film. Use synthetic sponges or soft cloths.
