California Energy Commission Includes Window Film in State Building Code

June 12th, 2012 by Editor

The California Energy Commission has recognized window film as an energy-efficient building product in recent changes to the California building code. The change to the code was voted through on May 31 and will go into effect in January of 2014.

“Every manufactured fenestration product shall have attached to it a clearly visible temporary label that lists the U-factor, the solar heat gain coefficient (SHGC) and Visual Transmittance (VT),” reads the building code. “Applied window films installed as part of an alteration complies with the U-factor, SHGC and VT requirement.”

The changes to the code require window film to have a National Fenestration Rating Council (NFRC) certification label, manufacturer’s name, a 10-year warranty certificate and compliance with the International Window Film Association’s (IWFA) visual quality standards.

“This addition to the code is a major step forward for energy efficiency in California, especially when considering the amount of untreated glass in the state in the majority of buildings,” said Darrell Smith, executive director of the IWFA. “The wide application of window film is a simple way to immediately cut utility demand generation and the resulting reduction of peak demand on utilities and greenhouse gases will further the state¹s reputation as an environmental leader.”

  1. This is a step in the right direction and it’s about time the rest of North America follows suit.

  2. Way too much government in every aspect of our lives! Products that work do not need to be forced upon us by the government.
