Spray Foam vs. Fiberglass Insulation

Do you need insulation installation for your home or building? You have a number of different options. Chances are you’re considering fiberglass and spray foam, two of the most commonly installed types of insulation.

For many years, fiberglass (batt and blown-in) has been the go-to material for home and commercial insulation, and it hasn’t lost its popularity. However, it’s not the only material! Although it’s been around for years, spray foam is considered a newer type of insulation than fiberglass. If you’re wondering which material better, we recommend finding out how they compare in different areas. This will help you make the most informed decision (along with guidance from professionals)!

Uses and Cost

Fiberglass most commonly comes in batts or rolls. These are available in standard dimensions meant to fit between wall studs, attic floor rafters and ceiling joists. You can also install blown-in fiberglass for irregularly sized spaces. Since fiberglass tends to be less expensive and readily available, you can insulate your entire home at an affordable price.

Spray foam is applied in a liquid state and expands into hard, thick foam. You can install spray foam insulation anywhere, from entire stretches of wall to tiny holes around electrical wiring penetrations. It is ideal for smaller and irregularly shaped areas because of its total coverage.


Traditional fiberglass has a heat flow resistance, or R-value, of R-3 per inch of thickness. Manufacturers also produce medium- and high-density fiberglass batt insulation with slightly higher R-values than the standard batts. When space is limited spray foam can be preferred to compressing fiberglass, but some brands of fiberglass insulation are particularly effective at maintaining R-value over time, not easily sagging or settling.


Fiberglass insulation is made of extremely fine glass fibers. Loose-fill fiberglass is made from molten glass that is spun or blown into fibers. Most manufacturers use 20 to 30% recycled glass content. Spray foam is typically made of polyurethane, which is a foam insulation material containing a low-conductivity gas in its cells.
