Styrofoam Highload 40 Insulation is a Type VI extruded polystyrene foam insulation with a minimum compressive strength of 40 psi. It is for use in high-load commercial, geotechnical, and other in-ground insulation applications. It resists compressive creep and fatigue and delivers long-term compressive strength and thermal performance in high-load applications.
