All building foundations come in contact with the ground. Wherever a building is located, water, temperature, air and soil on the foundation can impact the performance and integrity of the total structure. Continuous polyiso rigid foam insulation is an effective way to reduce foundation energy loss and protect against moisture problems. Rmax® Below Grade insulation and protection board delivers a high R-value per inch, excellent moisture resistance and superior foundation protection - all in one solution for below-grade exterior walls
