High-Density XPS Board B1 35 kg/m³ Flat Roof Grade
High-Density XPS Board B1 35 kg/m³ with 300 kPa compressive strength and 0.030 W/(m·K) conductivity for flat roof decks, underground retaining walls, and heavy-load industrial floor insulation systems.
// Key Features
- 300 kPa compressive strength supports heavy point loads on flat roof and podium slab applications
- B1 fire class at higher 35 kg/m³ density meets fire code for structural insulation assemblies
- ≤1.0% water absorption maintains thermal integrity in below-grade wet and damp environments
- Dimensionally stable under sustained compressive load for green roof and paved plaza systems
