Structural EPS Board 25 kg/m³ — ICF Block & Sandwich Panel Grade
Structural-grade 25 kg/m³ EPS board with compressive strength ≥120 kPa for ICF blocks and load-bearing sandwich panels. Thermal conductivity ≤0.035 W/(m·K). Used in precast concrete sandwich walls, ICF residential construction, and SIP structural systems.
// Key Features
- High compressive strength ≥120 kPa withstanding fresh concrete pour pressure in ICF applications
- Excellent surface bond adhesion to concrete and render for composite structural action
- Balanced thermal performance ≤0.035 W/(m·K) without compromising structural load capacity
- Tight dimensional tolerance ±2 mm ensuring accurate alignment in ICF block stacking systems
