STYROFOAM™ Highload extruded polystyrene insulation is a closed-cell foam insulation. Available in compressive strengths of 40, 60 and 100 psi (275, 415 and 690 kPa), STYROFOAM Highload insulation features superior moisture resistance and R-value* retention. All three STYROFOAM Highload insulation products resist compressive creep and fatigue, delivering long-term compressive strength. Like all STYROFOAM insulation products, STYROFOAM Highload 40, 60 and 100 are durable, versatile and reusable – making them the preferred choices for a variety of highload applications.
Moisture Resistance – Some insulation products absorb and hold water which reduces insulation performance and can lead to mold growth. STYROFOAM extruded polystyrene insulation resists water absorption and does not provide a nutrient source for molds. So, STYROFOAM insulation provides long-term insulating performance while reducing the potential for mold growth within the insulation.
Strength and Durability – Styrofoam insulation is rigid, so it\'s durable and maintains its intergrity during installation and for years after. Yet, it\'s easy to cut and work with.
