STYROFOAM High Load 40 extruded polystyrene insulation is a closed cell extruded polystyrene foam insulation designed to meet the high strength requirements of ASTM C578 (TYPE VI) specifications. It combines a minimum compressive strength of 40 PSI with the excellent physical property characteristics of all STYROFOAM extruded polystyrene insulation products. As a result, it resists compressive creep and fatigue and delivers the long term compressive strength and R-value retention needed for high load applications. It is ideal for use in low temperature (freezer floor) applications where moderately heavy loads are expected. It is also recommended for insulating many highway installations.

Building Code Compliance
Complies with ASTM C 578 Type VI. Meets IBC/IRC requirements for foam plastic insulation. See ICBO-ES ER 2257, BOCA-ES RR 21-02, NES NER 699, Und. Lab. Inc. ® Classified, see Classification Certificate D369.
**Not all product sizes are available in all regions.
† R means resistance to heat flow. The higher the R-value, the greater the insulating power. R-values are expressed in ft2•h•°F/Btu.
† † Vertical compressive strength is measured at 10% deformation (5% for STYROFOAM PLAZAMATE insulation and for STYROFOAM HIGHLOAD 40, 60 and 100 insulation products) or at yield, whichever occurs first. Since STYROFOAM extruded polystyrene and Dow polyisocyanurate insulation products are visco-elastic materials, adequate design safety factors should be used to prevent long-term creep. For static loads, 3-1 is suggested. For dynamic loads, 5-1 is suggested.
