Terrafoam EPS
Expanded Polystyrene Insulation, Types 1, 2, & 3

Product Description

TERRAFOAM Types 1, 2, and 3 are produced from inert closed cell expanded polystyrene (E.P.S.), with excellent resistance to freeze/thaw, zero capillarity and low moisture absorption. TERRAFOAM is manufactured in a wide range of densities in order to meet specific application requirements. TERRAFOAM will never rot or support mold or mildew. Insulating properties do not degrade over time. Beaver's manufacturing process permits exceptionally cost-effective client-designed fabrications.

Applications

• Perimeter insulation for grade beams and foundation walls.
• Under concrete slabs
• Available in 'ANR' grade for exterior insulated finish systems
• Above-grade cladding under stucco and siding
• Masonry Cavity Walls
• Roofs, in flat and tapered slope-to-drain
• Floatation applications
• Hot Tub Covers
• Packaging, shock and damage protection, container linings
• Client’s proprietary fabrications

Classifications

• TERRAFOAM meeting CAN/ULC S 701
  Type 1 – 70 kPa (10 psi) Compressive strength
• TERRAFOAM meeting CAN/ULC S 701
  Type 2 – 110 kPa (16 psi) Compressive strength
• TERRAFOAM meeting CAN/ULC S
  701 Type 3 – 140 kPa (20 psi) Compressive strength

Special note: TERRAFOAM HS-40 may provide "best service" for demanding geotechnical service as well as any other application where large panel sizes, thickness or very high compressive strength would be beneficial.

The thermal resistance of TERRAFOAM 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 is also more effective at lower temperatures. The R-Value increases as temperatures decrease. Check out the brochure for additional data.
