Foam Glass Insulation Block 430°C Underground Grade
Foam glass insulation block rated 430°C for underground applications. Zero water absorption and high density suit LNG tank ring beams, buried pipe trenches, and foundation slab thermal breaks.
// Key Features
- Zero water absorption in wet soil environments — long-term thermal performance guaranteed underground
- High bulk density resists soil overburden pressure and point loads without deformation
- Chemically inert to ground acids, alkalis, sulfates, and biological attack
- Self-supporting block form eliminates cladding or external support frames in below-grade installations
