Southwall Technologies V-Kool film is the only film on the market with such a favorable ratio of visible light transmission and heat rejection: 70 percent light transmission with 55 percent heat rejection. V-Kool VK-70 is a spectrally selective virtually clear applied film, made through a patented sputtering and layering process. V-Kool film does not darken windows, is not shiny or highly reflective, and provides clear visibility and preserves the building's original appearance. Other desirable properties include low emissivity, ultraviolet screening, and improvement in safety (film holds broken glass together). In addition to the clear film, VK-40, a softly tinted gray film, is available for a higher degree of heat, fade, and glare control. . V-Kool manages the marketing, sales, and distribution of V-Kool film for commercial use in North America.

1 GENERAL

1.1.1 Solar control film applied to existing glass.

1.2 SUBMITTALS

1.2.1 Submit under provisions of Section 01 30 00 - Administrative Requirements.

1.2.2 Product Data: Manufacturer's data on products to be provided, showing physical properties and including installation instructions.

1.2.3 Test Data: Independent testing agency reports showing compliance with properties specified by reference to a test method.

1.3 QUALITY ASSURANCE

1.3.1 Installer Qualifications: Experienced in application of self-adhesive window films, with at least 10 applications of similar size and complexity, and approved by manufacturer.

** NOTE TO SPECIFIER ** On a very large project, it may be useful to require a mock-up to verify that the installer actually knows how to do the work properly. The mock-up will also serve to verify that the proper color or tint has been selected, although changing the requirements at this point will probably be costly.

1.3.2 Mock-Up: Before proceeding with work, apply film to one window designated by Architect.

1.3.2.1 Accepted mock-up will constitute standard for workmanship for remaining work.

1.3.2.2 Accepted mock-up may remain.
