Terrafoam HS
High-Strength Rigid EPS Insulation
Terrafoam HS is a rigid, closed-cell expanded polystyrene insulation engineered for high-load applications where standard insulation products may not provide sufficient compressive resistance.
- High Compressive Strength
- Stable Long-Term R-Value
- Low Water Absorption
- No Thermal Drift
What is Terrafoam HS?
Terrafoam HS is a high-strength expanded polystyrene insulation designed for applications where both thermal performance and compressive resistance matter. Manufactured as a rigid, closed-cell EPS board, it is used where insulation must perform under higher loads while maintaining stable long-term R-value and dependable moisture resistance.
Terrafoam HS Applications
- Under concrete slabs
- Perimeter insulation for foundations and grade beams
- Frost protected shallow foundations
- Buried utility protection
- Bridge abutments and approach slabs
- Highway and railroad construction
