Insulation: Cellulose Insulation
Cellulose insulation is blown into attics and sprayed into wall cavities of a home to provide thermal and sound barriers. As a result of the installation process, cellulose reduces air leakage since it can be blown into difficult to reach spaces to eliminate gaps and voids. Since it is made primarily of recycled newsprint, it is an environmentally-friendly insulation option. The fibers are impregnated with fire retardant chemicals to make the insulation fire resistant. Spray-applied and loose-fill cellulose have an R-value of about 3.7per inch.
