In a freeze-thaw cycling test that simulated the stresses imposed on insulation in below-grade application, STYROFOAM brand insulation outperformed molded bead polystyrene by 216%, and foil-faced polyisocyanurate by 1,533% in R-Value retention.
Since the 1940's, STYROFOAM has a track record of long-term R-value retention that is second-to-none. Proven dependability and long-term R-value. That's what separates STYROFOAM brand insulation from the rest. It's been proven in tests and thousands of below-grade installations.
Installing DOW STYROFOAM Brand insulation below grade is significant in reducing heat loss.
Not only does DOW STYROFOAM keep the basement heat inside, it also keeps the ground cold outside.
