Product Description
Glass Wool Blanket Insulation (10–48 kg/m³)
High-performance thermal, acoustic, and fire protection insulation for building applications.
Manufactured using advanced centrifugal technology with eco-friendly thermosetting resin binders.
Key Features
- Thermal Insulation: Low slag ball content minimizes thermal conductivity for excellent heat preservation
- Flame Retardancy: A1 combustibility grade with outstanding flame resistance and thermal stability
- Noise Reduction: Micro-porous acoustic structure absorbs sound waves and converts them into kinetic energy
