Insulation Material

Insulation materials run the gamut from bulky fiber materials such as fiberglass, rock and slag wool, cellulose, and natural fibers to rigid foam boards to sleek foils. Bulky materials resist conductive and to a lesser degree convective heat flow in a building cavity.

There are three major types of insulation used in homes: foam, fiberglass, and cellulose. Foam insulation comes in two different forms, which are spray and injection foam. Spray foam is sprayed in an open cavity, like in new construction, attics, crawl spaces, rim joists, and pole barns, in a liquid state.
