Beaver Plastics TERRAFOAM is inert closed cell expanded polystyrene (E.P.S.) insulation, with excellent resistance to freeze/thaw, zero capillarity and low moisture absorption. It is manufactured in a wide range of densities in order to meet specific application requirements. TERRAFOAM will never rot, support mold or mildew and insulating properties do not degrade over time. Its manufacturing process permits exceptionally cost-effective client-designed fabrications.
Terrafoam is a breathable insulation product, permitting the transmission of water vapour. It can, therefore, be used as an external insulation for renovation and/or new construction without the potential for creating an exterior vapour barrier that would trap moisture in the wall cavity, causing serious building deterioration.
TERRAFOAM is one of the few foam plastic insulations available that contains absolutely no CFCs, HCFCs, or other refrigerant gases. It is non-toxic and hypo-allergenic, and will not irritate sensitive skin on exposure.
Expanded polystyrene should not be exposed to volatile hydrocarbons, such as fuels oils, gasoline, and some alcohols. Anhydrous acids, such as sulfuric, glacial and formic acid may also attack expanded polystyrene.
TERRAFOAM contains a chemical additive to inhibit accidental ignition from a small fire source. This additive, however, will not prevent burning when the material is exposed to a large continuous fire source or intense heat. Observe normal fire precautions and good housekeeping methods during application. Cover insulation with a finish acceptable to local building codes.
