PlastiSpan® 25 Insulation
Increased R-value & compressive resistance

PlastiSpan® 25 Insulation is used in Exterior Foundation, Slab on grade and Ice Rinks.


PlastiSpan 25 Insulation is a moulded expanded polystyrene (EPS)
insulation.It meets or exceeds the requirements of CAN/ULC-S701,Standard
for Thermal Insulation, Polystyrene, Boards and Pipe Covering. The closed
cell structure of PlastiSpan 25 insulation resists water absorption so it will
retain its R-value even in applications where severe temperature
differentials occur.

• Meets all building code requirements
• Meets CAN/ULC-S701, Type 3
• Long term thermal resistance - RSI 0.74/25 mm (R-value 4.27/inch)
• Closed cell insulation resists moisture
• CCMC 12426-L

Continuous insulation eliminates thermal bridging, increasing your total
effective RSI/R-value. This reduces energy costs and increases your
energy savings.

CAN/ULC-S701-11, Standard for Thermal Insulation, Polystyrene,
Boards and Pipe Covering
is the National Standard of Canada for moulded
expanded polystyrene (EPS) insulation. The table below provides material
properties for PlastiSpan 25 insulation meeting CAN/ULC-S701, Type 3.
