PlastiSpan® Insulation
The most cost-effective rigid insulation

PlastiSpan® Insulation is used in Cathedral Ceiling, Continuous Insulation, Exterior Foundation, Interior Basement Walls, Basement Floor, Under Slab, Hydronic, EIFS and handi-pac Packaging & Display.


PlastiSpan Insulation is a moulded expanded polystyrene (EPS) insulation.

• Meets all building code requirements
• Meets ASTM C578, Type I
• Thermal resistance - R-value 3.9 per inch
• Closed cell insulation resists moisture


EPS is a closed cell, rigid foam plastic insulation that does not contain a
blowing agent that provides a temporary increase in thermal resistance.

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).
