PlastiSpan® 40 Insulation
High compressive resistance for geotechnical applications

PlastiSpan® 40 Insulation is used in Roadways, Sidewalks and Utilities.


PlastiSpan 40 insulation is a closed cell expanded polystyrene (EPS)
insulation that meets or exceeds the requirements of CAN/ULC-S701-11,
Standard for Thermal Insulation, Polystyrene, Boards and Pipe
Covering.
PlastiSpan 40 insulation closed cell structure resists water
absorption so it will retain its R-value even in applications where severe
temperature differentials occur.

PlastiSpan 40 insulation provides a minimum compressive resistance of
276 kPa (40 psi). The high compressive resistance makes it ideal for use in
applications where heavy loads are expected such as low temperature
freezer floor or highway construction. PlastiSpan 40 insulation resists
compressive creep and fatigue to deliver specified compressive resistance
on the long term.

• Compressive Strength 40 psi
• Road applications
• No thermal drift
• Less than 2% water absorption

2x8 ft, 4x8 ft

PlastiSpan 40 insulation meets or exceeds the requirements of
CAN/ULC-S701, Standard for Thermal Insulation, Polystyrene, Boards
and Pipe Covering
, the National Standard of Canada for expanded
polystyrene (EPS) insulation.
