Thermal Insulation and Energy Efficiency
Thermal insulation is an important element of energy conservation. It helps keep homes and commercial buildings warm in the winter and cool in the summer. Properly installed, thermal insulation lowers utility costs and cuts energy consumption. Thermal insulation improves energy efficiency, which reduces greenhouse gases that contribute to global climate change.
The Bureau is responsible for ensuring thermal insulation products offered for sale in California perform at the level stated by the manufacturer. We license thermal insulation manufacturers, certify thermal insulation products, and conduct periodic compliance testing of samples.
If the Bureau finds thermal insulation products that do not perform as certified and are found to be in violation, we have the authority to order that the product be withheld from sale and take action against the manufacturer.
We publish an annual directory of thermal insulation products that have been certified and tested to California insulation quality standards. The directory is posted on this web site and is also available on CD format. You may request a CD copy of the directory by email or through a written request by mail to 4244 South Market Court, Suite D, Sacramento, CA 95834-1243.
