An integrated industry body of window film manufacturers, distributors and dealers, the International Window Film Association (IWFA), announced that California is the first state in the U.S. to add window film into its building code.
The window film is a polymer material that offers several benefits. Key factor for adding the window film into the building code is its proven cost-effective energy savings. The material can considerably decrease energy consumption as well as minimize interior fading of furnishings, UV exposure to skin, glare and the impact of glass breakage.
The change to the California building code was voted by the California Energy Commission on May 31, 2012 and it will be effective from January 2014. This means that the window film is recognized as a building product similar to glass and roofing materials, but mainly for retrofit applications. The state’s new building code requires a manufacturer’s name, a National Fenestration Rating Council (NFRC) certification label, compliance with the IWFA’s Visual Quality Standards and a 10-year warranty certificate. The code can be used by contractors and remodelers for additional guidance.
According to a report offered by ConSol, based in California, the majority of existing homeowners will be able to achieve considerable energy savings and homes with single pane glass can attain a greater energy benefit than using R-38 insulation materials in their ceilings. NFRC, a group that certifies energy control performance of window films, skylights, doors and windows, has recognized the window film.
