DOW STYROFOAM™ brand insulation products feature closed cell structure and maintain their R-value over time. The extruded polystyrene insulation products offer the highest moisture resistance of any foam plastic insulation. The result is high compressive strength and unparalleled resistance to water penetration. The polyisocyanurate insulation products do not readily absorb moisture.
R-Value– A measurement of resistance to heat flow. The greater the R-value, the greater the thermal efficiency—and a small increase makes a big difference. Cavity insulation only insulates between the studs, leaving those studs un-insulated. Rigid insulation covers the entire wall, providing a continuous layer of thermal protection and increasing the overall R-value and energy efficiency.
