PlastiSpan® 30 Insulation
Higher R-value and higher compressive resistance
PlastiSpan® 30 insulation is a closed cell expanded polystyrene (EPS)
insulation that meets the requirements of CAN/ULC-S701, Standard for
Thermal Insulation, Polystyrene, Boards and Pipe Covering and ASTM
C578, Standard Specification for Rigid, Cellular Polystyrene Thermal
Insulation.
The closed cell structure of PlastiSpan 30 insulation resists water absorption
so it will retain its R-value even in applications where severe temperature
differentials occur. PlastiSpan 30 insulation has a range of compressive
resistance values which makes it ideal to insulating floors, foundations or
any application where heavy loads are expected. PlastiSpan 30 insulation
material property values for use in load bearing applications are provided
below.

Dependent upon the initial deformation due to a compressive load, sustained loads on PlastiSpan 30
insulation may result in deflection much greater over time. Figure 1 provides a series of curves
representing the long term deflection over time for various EPS insulation densities based
upon sustaining compressive loads at different % strain levels.
It should be noted that compressive resistance at 1% strain is within the elastic limit for the
PlastiSpan insulation types in the above table and is accepted as the design compressive resistance
to limit long-term deformation under structural load. Compressive resistance at 10% strain is not used
for design purposes when an insulation material will be under compressive load. It is typically used for
quality control purposes or may be applicable for end-uses where the application requires long-term
deformation under structural load – i.e., a compressible product.
