PlastiSpan 20 insulation is a moulded expanded polystyrene (EPS) insulation. EPS is a closed cell, rigid foam plastic insulation.

PlastiSpan insulation applied as continuous insulation over foundations, walls and roofs eliminates thermal bridging, increasing your total effective R-value. This reduces energy costs and increases your energy savings.

PlastiSpan expanded polystyrene (EPS) insulation conforms to ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation, as detailed below.

PlastiSpan insulation has also been evaluated for conformance with the requirements of ICC-ES AC12, Acceptance Criteria for Foam Plastic Insulation per ICC-ES Evaluation Report ESR-1587 and Intertek Code Compliance Research Report CCRR-1072 (see Code Support section in Technical Library for additional information).
