While we have grown into the largest independent polyurethane systems supplier in the United States, we have not lost sight of our roots or the reasons for our continued success. We are still a family business at heart, holding strong to simple, common sense beliefs like meaning what we say, caring about every customer’s success, and always striving to do the right thing.
The U-factor, or thermal transmittance, is a measure of the thermal conductivity for a building enclosure assembly (e.g., wall, floor, ceiling, roof) or a building component (e.g., window, door). Incorporating parallel and series conductive heat transfer principles and the R-value or thermal conductivities of each component in the assembly, the U-factor can be calculated. The U-factor, when multiplied by the surface area and the indoor-outdoor temperature difference, predicts the amount of heat loss through the assembly, which means assemblies with low U-factor are more energy efficient. U-factors are typically expressed as (Btu/hr•ft2•F) or (W/m2•C).
SPFA believes that the path to a healthful, safe, high-quality and performing SPF installation travels through the hands of a knowledgeable, trained, experienced, and ideally PCP-certified professional contractor.
