PlastiSpan Insulation is a Type 1, moulded expanded polystyrene (EPS) insulation with an R-value of 3.75 per inch and compressive resistance of 10 psi. PlastiSpan is a versatile insulation product that can be used in a wide range of applications.

PlastiSpan EPS is a closed cell, rigid foam plastic insulation that maintains its R-value for the life of the product. When applied as continuous insulation over foundations, walls and roofs, PlastiSpan insulation is a cost-effective solution that eliminates thermal bridging, increasing your total R-value. By increasing your energy efficiency with PlastiSpan insulation, you will effectively reduce your heating and cooling costs.

PlastiSpan Insulation is code listed with CCMC 12424-L and meets the requirements of CAN ULC S701.1, Type 1.
