Understanding R-Value

R-Value is the rating system used to grade insulation products or a material's insulating properties. The "R" stands for "resistance" and refers to the resistance a material has to heat flow, or temperature conduction. When a product or home has a high R-Value, this means it is well insulated.

USA Premium Foam® has the 
highest R-Value in its class.

Now that you know what R-Value is, how does our premium insulation product compare? Our proprietary USA Premium Foam Insulation has a superior R-Value of 5.1 per inch, which is 35% higher than any retrofit stud wall application. In fact, it's the highest on the market.

Our product's R-Value is higher than:

  • Rigid panels
  • Other spray foam insulation
  • Rockwool
  • Fiberglass
  • Cellulose
  • Blown-in insulation

Is my home's R-Value high enough?

The United States Department of Energy warns homeowners that just 1 in 5 homes constructed prior to 1980 are sufficiently insulated. While homes constructed today are required to meet R-Value standards set by the U.S. Department of Energy, this requirement was not included in building codes prior to the mid-1970s. This means that approximately 80% of homes built before this time are in need of better insulation! If you're uncertain if your home falls within this category, contact us and our energy experts can help you determine if you're in need of insulation.
