PART 1 – GENERAL
1.1 SUMMARY
A. Section Includes:
1. Abrasion-resistant, solar control, reflective window film. Film is designed to reduce gain of solar heat energy through window by reflecting more to the exterior than interior. Traditional metalized films reflect equally both inside and outside, where you need it, and less to the inside. The Night Vision line reflects more to the outside, where you need it, and less to the inside, where you do not need it. 3M Night Vision, carbon impregnated polyester layer provides outstanding heat rejection performance.
1.2 SYSTEM DESCRIPTION
A. Performance Requirements:
1. Provide reflective films that comply with the following:
B. Film Attributes: The following attribute information is based upon 1/4 inch (6 mm) clear glass unless indicated otherwise:
1. Adhesive System: Pressure sensitive, weatherable, acrylate adhesive applied uniformly over surface opposite abrasion resistant coated surface.
a. Viewing film from a distance of 10 feet (3 m) at angles up to 45 degrees from either side of glass, film shall not appear distorted.
2. Flammability: Class A Interior Finish for Buildings Materials for both Flame Spread Index and Smoke Development Values per ASTM E84.
3. Abrasion Resistance: Surface coating resistant to abrasion, with less than 5 percent increase of transmitted light haze resulting per ASTM D1044 using 100 cycles, 500 grams of weight, and CS10F Calbrase Wheel.
1.3 SUBMITTALS
A. Product Data: Manufacturer’s product data including installation instructions and cleaning methods.
B. Warranty: Manufacturer’s standard limited warranty indicating warranty coverage.
1.4 DELIVERY, STORAGE, AND HANDLING

PART 3 – EXECUTION
3.1 EXAMINATION
A. Examine glass surfaces to receive film and verify that they are free from defects and imperfections, which will affect final appearance. Correct and note such deficiencies to [Owner] [Architect] prior to commencing film application.
3.2 PREPARATION
A. Use protective tarps and drop cloths to cover interior finishes near window.
B. Turn off or cover heating and air conditioning ventilation ducts.
C. Clean window and window framing thoroughly with cleaning solution consisting of 90 percent water and 10 percent ammonia. Blade inside surface of window glass with industrial razors to insure removal of foreign contaminants. 1. Tape and seal cracked and deteriorating window sealant.
D. Place towel or other absorbent material on window sill or sash to absorb moisture accumulation generated by film application.
E. Thoroughly rinse glass from top to bottom with pressure spray tank.
F. Squeegee entire glass surface.
G. Dry glass edges and window frames using a lint-free towel.
3.3 INSTALLATION
A. Install window films per manufacturer’s written instructions.
1. 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.
2. Spray slip solution, composed of one capful of Johnson® Baby Shampoo or Joy® Dish washing Liquid to 1 gallon of water, on window glass and adhesive to facilitate proper positioning of film.
3. Apply film to glass and lightly spray film with slip solution.
4. Squeegee to remove water. Squeegee from top to bottom of window.
5. 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. Wipe frame edge dry
8. Inspect installation to insure proper application.
9. 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.
3.4 CLEANING
A. 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.
B. After installation, remove left over material and debris from Work area. Use necessary means to protect film before, during, and after installation.
