Foam board insulation with a range of high compressive strength High Density (HD) Envirosheet is a high density economical foam board insulation made from Expanded Polystyrene (EPS) offering a high R-value per dollar. It is a highly durable and cost-effective product that is primarily designed to be used for below grade applications for residential or commercial construction. The closed-cell structure gives the board superior water resistive properties while the high density of the foam makes for an excellent alternative for projects where high compressive strength is required. High Density (HD) Envirosheet comes in multiple densities and is available in a various sizes and thicknesses. The availability of larger panels helps improve job site efficiency and reduce labor cost. The high compressive strength makes it the ideal solution for majority of below grade applications such as foundation walls and below concrete slabs.
