Performance and Cost Comparison

When you look at thermal performance, spray foam offers R-values of 6-7 per inch while rockwool provides 3-4 per inch. This means spray foam works better in homes that face extreme temperatures. You'll notice the price difference too - spray foam ranges from $2.00-$9.00 per square foot, while rockwool costs between $0.62-$1.10 per square foot.

Long-Term Value

Don't let the higher upfront cost of spray foam discourage you. As a USA Spray Me spokesperson explains, "Our analysis shows spray foam creates a seamless air barrier that prevents energy loss and reduces utility bills. The initial investment pays off through improved home comfort and decreased energy consumption."

Key Performance Differences

The way these materials perform varies in important ways. Spray foam expands to fill all gaps and blocks air movement completely. Rockwool, while effective, might leave small spaces that allow some air to pass through. If fire safety concerns you, rockwool naturally resists fire, while spray foam needs added fire retardants. Both options will help reduce noise in your home.

Services for Northern California Homeowners

For Northern California homeowners, USA Spray Me offers both open-cell and closed-cell spray foam options. You might prefer closed-cell foam if you need extra moisture protection and density for your space.

The full report covers everything from how these materials affect your energy bills to their environmental impact. You'll find helpful information about which option works best for your climate and budget. Whether you live in a cold area that needs superior insulation or a moderate climate where either option might work well, the report offers clear guidance.
