As demand for spray foam insulation grows, so does supply. There are new SPF manufacturers popping up every year, including non-US-based companies. Even some companies who once competed with SPF suppliers by selling other forms of insulation have updated their business models and gotten into the spray foam insulation market. Everyone wants a piece of the energy efficient, builder and resident-friendly material known as spray foam.With more competition comes a wider range of quality and a deeper selection, so it’s imperative for architects, builders, general contractors, homeowners, and building owners to do their homework before choosing a brand. Each manufacturer formulates their brands/products differently, thus each brand is different than that of another company. They have different attributes, different R-values, different qualifications, certifications and ICC reviews, and different customer reviews/reputations. Bottom line is, some are better than others, and the same goes for manufacturers.
Conventional consumer wisdom and US energy codes lead us to believe higher R-value equates to better insulating value. In theory, materials with higher R-values should be more effective as insulation and thus be more environmentally efficient. But the reality is that R-value is just one measure of insulating quality—and an imperfect one at that. In order to get an accurate gauge of the actual thermal resistance and energy efficiency of an insulating material there are other factors that should be considered.
Spray foam insulation, or SPF, has been used regularly in both residential and commercial buildings since the 1970s, so we now have more than thirty years of performance data and scientific testing to analyze when determining the health and safety of this material. As a result, experts agree spray foam is safe and chemically inert if it is:
