By now, most of us are pretty familiar with the products available on the market that have specific “green” attributes. However, in the Spray Polyurethane Foam (SPF) insulation world, all SPF has one very important such attribute: energy savings.
Spray foam insulation can dramatically reduce the energy required to heat or cool buildings. And use of SPF insulation also helps reduce electricity demand, conserving valuable fossil fuels and lowering the associated greenhouse gas emissions typically emitted during the production of electricity.
Some of today’s SPF products are developed with renewable resources– think natural oil polyols based on soybean or castor oil. These natural polyols are chemicals that are combined and reacted with other chemicals to create polyurethane foam. The finished and reacted polyurethane foam typically has only a portion of its content as considered “bio-based.”
How Can You Better Interpret ‘Green’ SPF Insulation Marketing Claims?
When comparing SPF products, one of the first things you need to look for is the R-value of the product. This means its resistance to heat flow. The higher the R-value, the greater the insulating power.
The Federal Trade Commission (FTC) offers helpful guidance on understanding R-value in its Consumer Alert – Home Insulation Basics: Higher R-Values = Higher Insulating Values. It’s important to understand that federal regulations require insulation installers to give customers a contract or receipt for the insulation installed illustrating the coverage area, thickness and R-value of the insulation.
