What is the insulation advantage to building with SIPs?
R-Value is a measure of a material’s resistance to heat flow. The higher the number the better the material is at insulating. According to the Dept. of Energy, thermal breaks such as corners, windows, doors, and stud walls dramatically reduce the stated R-Value of virtually every product on the market except SIPs. As an example, a 2×6-stud wall with R-19 fiberglass batts has an R-Value of 13.7. A six-inch Premier wall has an R-Value of 21.7. Simply put, a 6″ Premier wall out performs a 6″ stud wall by 58%. Premier Panels have the following ratings: The energy efficiency of an entire wall assembly has been documented by Oak Ridge National Laboratory, (ORNL). The testing method takes into account energy losses for the structural members, corners, joints and around windows, not just the value of the insulation.
