Terrafoam® EPS from Beaver Plastics is a rigid insulation board that comes in a wide range of sizes and densities, ensuring that it meets Building Codes and your exact application requirements. It is a cost-effective option and does not contain harmful chemicals such as CFCs or HCFCs. Terrafoam EPS is also non-toxic and hypoallergenic, and it never rots or allows mold and mildew to grow. Terrafoam is also more effective at lower temperatures; the R-value will increase as temperatures decrease.
