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 CAN/ULC-S701, Type 1
• Thermal resistance - RSI 0.65/25 mm (R-value 3.75/inch)
• Closed cell insulation resists moisture
• CCMC 12424-L

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
RSI/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
(see Plasti-Fab Product Information Bulletin No. 269 for additional
information).




The table below provides material properties for PlastiSpan insulation meeting CAN/ULC-S701, Type 1.

1Thermal resistance values are minimum requirements per C578 at mean temperature of 75 ºF (24 ºC).
2Design thermal resistance values are provided at mean temperatures of 40 ºF (4.4 ºC) and 75 ºF (24 ºC). 
3ASTM Test Method C272 water absorption requires 24 hours submersion of specimen under water. The water
absorption values above are applicable to specific end-use design requirements only to the extent that the
end-use conditions are similar to requirements stated in the test method.
