Glass Wool Board 48 kg/m³ Medium Density
Glass Wool Board 48 kg/m³ medium-density for external wall and curtain wall insulation. Enhanced rigidity and dimensional stability suit steel structure facades, industrial building envelopes, and cladding systems.
// Key Features
- Higher rigidity at 48 kg/m³ prevents sagging in vertical external wall installations
- Low thermal conductivity 0.031 W/(m·K) exceeds GB 50189 building energy efficiency targets
- Excellent dimensional stability under cyclic thermal loading in curtain wall cavities
- Class A1 fire rating satisfies requirements for high-rise building facade insulation
