The CA Energy Commission (CEC) has set a standard for the way insulation should be installed in a home called High-Quality Insulation Installation (QII). In order to meet QII, insulated framing areas need to resist thermal bridging of the assembly separating conditioned from unconditioned space. This visual inspection is conducted by a “third party” called a certified HERS Rater. They inspect to ensure that the assemblies are air-sealed as well as insulated in a way to where the insulation fills 100% of the cavity without gaps voids or compressions, allowing the home to perform per the insulation manufacturer’s specifications.
