Quality Insulation inspections are performed by a HERS (Home Energy Rating System) Rater and verify that the insulated framing areas of a new house or an addition comply with the California Energy Commission’s standards for insulation installation called High Quality Insulation Installation (QII). QII is a prescriptive measure that adds to a building’s U-factor, which is used in energy modeling calculations.

Common Mistakes to Avoid When Hiring an Insulation Contractor for Your Project

QII requires that the insulation thickness of attic blown-in insulation be within 30% of the manufacturer’s minimum required settled insulation thickness to achieve the specified R-value. It also requires that the insulation be free of voids, gaps, and compression. This procedure is based on industry standards and is similar to widely recognized national standards like RESNET and Energy Star.

Loose-fill insulation is a mixture of loose fibers or foam pellets, typically made of processed fiberglass, mineral wool or cellulose that is blown into walls, floors, attics and roof cavities. It is ideal for retrofits because it can fit into crevices and voids without disturbing structures or finishes.

Foam board insulation is rigid panels that are a good choice for sheathing, basement walls, attic hatches and other applications where it is difficult to access with other types of insulation. Foam blocks are an excellent choice for SIP-built homes and other forms of prefabricated construction. These molded blocks of foam are assembled to form the walls and roof of a home and can yield a superior insulated wall.
