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
