Terrafoam HS-40
High Strength EPS Insulation

Product Description

TERRAFOAM HS-40 is a high compressive strength board with unusual physical properties. It is inert closed cell expanded polystyrene (E.P.S.) insulation, with excellent resistance to freeze/thaw, zero capillarity and low moisture absorption. TERRAFOAM HS-40 is a "green" alternative to extruded polystyrene, as it uses no chemical gases that might contrite to global warming or attack the earth's ozone layer. HS-40 will never rot, support mold or mildew and insulating properties do not degrade over time. It's compressive strength is minimum 276 kPa (40 psi).

Applications

• Perimeter and sub-grade Installations
• Under concrete slabs and other geotechnical applications
• Heavy duty under-slab insulation
• Masonry cavity walls
• Roofs, in flat and tapered slope-to-drain
• Floatation applications
• Coolers, freezers, and ice arenas
• Runways, taxiways, and aprons

Classifications

• ASTM C-578 – 09
• CAN/ULC S 701 Type 2 (Minimum)
• ASTM D-6817 - 07

The thermal resistance of TERRAFOAM HS-40 is permanent! R-Value drift will occur with some insulation products because the insulating blowing gases (HCFCs) will eventually escape. Since EPS contains ordinary air, R-Value will remain the same, indefinitely.

TERRAFOAM HS-40 is also more effective at lower temperatures. The R-Value increases as temperatures decrease. Download our brochure for additional data.
