Spray Foam vs. Fiberglass

Two of the most popular types of insulation are spray foam and fiberglass. But how do you know which one to choose for your particular insulation project? It’s important to learn the benefits of each material before making a decision. Keep reading for specific benefits of spray and fiberglass insulation, so you can make the most informed choice before scheduling insulation services.

Spray Foam Insulation

Spray foam is made of polyurethane in either a closed-cell or open-cell formula. Closed-cell spray foam is filled with a low-conductivity, non-HCFC gas to help the material expand and fill the space around it. This type of spray foam reaches R-values of R-5.5 to R-6.5 per inch. Open-cell spray foam is spongier and less dense and achieves about R-3.6 per inch.

Both types of spray foam are sprayed directly into open wall or attic floor cavities, and expands to seal and fill the cavity completely. Spray foam is ideal for areas around piping and wiring.

Fiberglass Insulation

Fiberglass is made of tiny glass fibers and is often installed in attics but can be used to insulate walls and crawl spaces as well. It’s commonly found in two forms: batts and loose-fill. Medium-density batts provide an R-value of just over R-3 per inch. They come in standard sizes to fit between ceiling, wall and floor joists built to code.

Loose-fill fiberglass is made of molten glass spun into fibers. Most manufacturers use 20 to 30 percent recycled glass for a more environmentally friendly insulation material. While loose-fill requires a special blowing machine to apply the insulation, loose-fill fiberglass is ideal for oddly shaped and hard-to-reach areas. Loose-fill offers R-2.2 to R-2.7 per inch.
