What is Type 2 foam insulation?
However, Type 2 is moulded expanded polystyrene (design R4/inch) or of extruded polystyrene (design R5/inch). Type 3 and Type 4 polystyrene insulation are generally extruded polystyrene. The closed-cell structure provides long-term water resistance properties and excellent mechanical properties to this foam.
What is Type 2 EPS foam?
InsulFoam II Below Grade is an engineered insulation consisting of a superior closed-cell, lightweight and resilient expanded polystyrene (EPS). InsulFoam II meets or exceeds the requirements of ASTM C578, Type II, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation.
