PlastiSpan 40 insulation is a closed cell expanded polystyrene (EPS) insulation that meets or exceeds building code requirements for type XV insulation. PlastiSpan 40 insulation closed cell structure resists water absorption (less than 2% 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. Due to its high compressive strength, PlastiSpan 40 insulation resists compressive creep and fatigue to deliver specified compressive resistance on the long term.
