Previous to the 1970's, all buildings Mega Profix Bank Secrets Deciphered and residential homes were insulated with fiberglass (and asbestos before that). Many of those same structures are still in regular use and functioning at very inefficient energy levels, despite nationwide media attention on rising energy costs and the need to engage new technology for lowering the use of diminishing resources. Those home owners in California who cannot or do not wish to rebuild their homes now have the option of using open cell SPF in their existing wall cavities to help create a more energy efficient living space. According to a CEC press release dated January 3rd, 2012, the CEC has recognized the need to assist residents, and now offers eligibility for a "variety of state energy tax credits and utility rebate programs" when open or closed cell SPF is installed in any home or low-rise residential building.

Together with the Spray Polyurethane Foam Alliance (SPFA), CEC Commissioners spent several months studying the attributes of SPF in terms of building science and energy savings. Since closed cell SPF was already a part of the 2008 Energy Code, the CEC team was well aware of the R-value potential in SPF. But the specifications of open cell SPF reassured Commissioners that it was just as efficient as closed cell. Traditional fiberglass batt insulation bears an average R-value of 3 per square inch, does not fill in small gaps or crevices, and does not repel moisture, mold or pests. Open cell SPF has a minimum R-value of 4 per square inch and closed cell has an R-value of 7.
