TERRAFOAM® HS 30 is a closed cell high compressive resistant polystyrene insulation product used for geotechnical service. It should be used wherever large slab loads or lateral earth forces would compress typical insulation products.

TERRAFOAM HS provides stable thermal performance for the life of the structure, without using blowing agents that contribute to global warming. It is totally CFC and HCFC free. TERRAFOAM® HS can be used in low temperature applications such as freezers and coolers, under streets and highways, airport taxiways, bridge abutments and approach slabs, plaza decks, underground parking structures, and skating arenas and curling ice. Contact Beaver Plastics for specific design considerations.

TERRAFOAM is also more effective at lower temperatures, R-Value increases as temperatures decrease.
