2.0 Requirements of the Film
Film Material – Clear: The film material shall consist of an optically clear polyester film, with a durable acrylic abrasion resistant coating over the surface. The film color is clear.
The Polyester film shall have a nominal thickness of 4 mils (0.004 inches).
There shall be no evidence of coating voids.
The film shall be identified as to Manufacturer of Origin (hereafter to be called Manufacturer).
2.1 U Value: The U Value of the film applied to 1/4″ (6mm) clear glass shall be measured in accordance with test procedures described in 3.2 for Emissivity.
2.2 Transmission – Visible: When applied to 1/4″ (6mm) clear glass, the luminous transmittance shall be nominal when measured with an integrating sphere spectrophotometer as referenced by ASTM E-903 and calculated per ASTM E-308 using Standard Source “C” for average daylight.
2.3 Reflection – Visible: When applied to 1/4″ (6mm) clear glass, the total luminous reflection from the glass surface shall be nominal when measured with an integrating sphere spectrophotometer as referenced by ASTM E-903 and calculated per ASTM E-308 using Standard CIE Source “C” for average daylight.
2.4 Transmission – Ultraviolet Light: When applied to 1/4″ (6mm) clear glass, the total transmission of solar ultraviolet radiation of air mass = 2 over the spectral range of 3000 to 3800 angstroms shall not exceed when measured with an integrating sphere spectrophotometer as referenced by ASTM E-903.
2.5 Shading Coefficient: When applied to 1/4″ (6mm) clear glass, the shading coefficient and energy transmittance and reflection are measured per ASTM E-903 and the shading coefficient is computed in accordance with the established procedures defined by The ASHRAE Handbook of Fundamentals.
2.6 Adhesive System: The film shall be supplied with a high mass pressure sensitive weatherable acrylate adhesive applied uniformly over the surface opposite the abrasion resistant coated surface. The adhesive shall be essentially optically flat and shall meet the following criteria: a. Viewing the film from a distance of ten feet at angles up to 45 degrees from either side of the glass, the film itself shall not appear distorted. b. It shall not be necessary to seal around the edges of the applied film system with a lacquer or other substance in order to prevent moisture or free water from penetrating under the film system.
2.7. Abrasion Resistance: The Manufacturer shall provide independent test data showing that the film shall have a surface coating that is resistant to abrasion such that, less than 5% increase of transmitted light haze will result in accordance with ASTM D-1044 using 100 cycles, 500 grams weight, and the CS10F Calbrase Wheel.
2.8. Safety Glazing: The film, when applied to either side of the window glass, shall pass a 100 ft/lb. impact when tested according to ANSI Z97.
2.9. Tensile Strength: The film shall have an average tensile strength of 28,500 PSI when tested in accordance with ASTM D882-95a.
2.10 Elongation: The film shall have an average elongation of 125% when tested in accordance with ASTM D-2582-95a.
2.11 Break Strength (1 inch per width): The film shall have average break strength of 28 lbs. per mil of film thickness.
3.0 Requirements of the Authorized Dealer/Applicator (ADA)
3.1 The ADA shall provide documentation that the ADA is certified by the Manufacturer of the window film to install said window film as per the Manufacturer’s specifications and in accordance with specific requests as to be determined and agreed to by the customer.
3.2 Authorization of dealership may be verified through the company’s 3M ID Number.
3.3 The ADA will provide a commercial building reference list of ten (10) properties where the ADA has installed window film. This list will include the following information: * Name of building * The name and telephone number of a management contact * Type of glass * Type of film * Amount of film installed * Date of completion
3.4 Upon request, the ADA will provide a Glass Stress Analysis of the existing glass and proposed glass/film combination as recommended by the film Manufacturer.
4.0 Requirements of the Manufacturer
4.1 The Manufacturer will insure proper quality control during production, shipping and inventory, clearly identify and label each film core with the product designation and run number.
4.2 The Manufacturer will, upon request and pre-approval, provide 100% financing for the complete installation of the window film to the end-user customer in either an installment purchase or lease purchase format to be decided upon by customer.
5.0 Application
5.1 Examination: Examine glass surfaces to receive new film and verify that they are free from defects and imperfections, which will affect the final appearance. Correct all such deficiencies before starting film application.
5.2 Preparation:
a The window and window framing will be cleaned thoroughly with a neutral cleaning solution. The inside surface of the window glass shall be bladed with industrial razors to insure the removal of any foreign contaminants.
b Toweling or other absorbent material shall be placed on the window sill or sash to absorb moisture accumulation generated by the film application.
5.3 Installation: The film shall be applied as to the specifications of the Manufacturer by an ADA. Materials will be delivered to the job site with the manufacturer’s labels intact and legible.
b. To minimize waste, the film will be cut to specification utilizing a vertical dispenser designed for that purpose. Film edges shall be cut neatly and square at a uniform distance of 1/8″ (3 mm) to 1/16″ (1.6 mm) of the window-sealing device.
c. Clear, clean water will be used to remove the water soluble overcoat that protects the pressure sensitive adhesive. Water and film slip solution only will be used on the window glass to facilitate the proper positioning of the film.
d. To insure efficient removal of excess water from the underside of the film and to maximize bonding of the pressure sensitive adhesive, polyplastic bladed squeegees will be utilized.
e. Upon completion, the film shall have a dimpled appearance from residual moisture. Said moisture shall, under reasonable weather conditions, dry flat with no moisture dimples within a period of 30 calendar days when viewed under normal viewing conditions.
f. After installation, any left over material will be removed and the work area will be returned to original condition. Use all necessary means to protect the film before, during and after the installation.
6.0 Cleaning
6.1 The film may be washed using common window cleaning solutions, including ammonia solutions, 30 days after application. Abrasive type cleaning agents and bristle brushes, which could scratch the film, must not be used. Synthetic sponges or soft cloths are recommended.
7.0 Warranty
7.1 In that the film will maintain solar reflective properties without cracking, crazing, delaminating, peeling, or discoloration. In the event that the product is found to be defective under warranty, the film manufacturer (3M) will replace such quantity of the film proved to be defective. The application shall be warranted by the film manufacturer (3M) for a period of five (5) years additionally provide the removal and reapplication labor free of charge.
