Beaver Plastics TERRAFOAM is an inert closed cell expanded polystyrene (E.P.S.) insulation material. It has excellent resistance to freeze/thaw and has zero capillarity and low moisture absorption properties. TERRAFOAM will never rot, or support mold or mildew. TERRAFOAM is manufactured in a range of densities, in order to meet specific application requirements. Standard sheet sizes are 2'X8' and 4'X8', but TERRAFOAM is also produced to custom sizes, with edges plain or ship-lapped. It contains ordinary air; not refrigerant gases. This means that insulating properties do not degrade over time.
TERRAFOAM can be used on roofs, under both conventional built-up and single ply membranes. Panels can be produced in flat or tapered configurations that will provide slope-to-drain. TERRAFOAM is also used in walls, under slabs and as perimeter insulation for grade beams, foundation walls and buried in soil for shallow foundation designs. TERRAFOAM is available in 'ANR' grade, which is conditioned and sized expressly for exterior insulated finish systems. TERRAFOAM is resistant to soil weight and pressure, and can be specified for all below-grade applications. The following is a sampling of common applications.
TERRAFOAM is manufactured to CAN/ULC-S701-97 for Type 1, 2 and 3.
