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.
