Glass Wool Boards
Glass wool board is a rigid or semi-rigid insulation material made by bonding glass fibers with a thermosetting resin. It has a uniform structure, low thermal conductivity, and good mechanical strength.
Common Specifications
*Density: 24–100 kg/m³
*Thickness: 25–100 mm
*Size: 1200×600 mm (or customized)
*Facings available: Aluminum foil, fiberglass cloth, non-woven fabric, etc.
Key Advantages:
* Excellent thermal insulation – keeps buildings and equipment energy-efficient
* Good sound absorption – reduces noise in offices, factories, and public spaces
* Class A fire resistance – non-combustible, safe for high-rise buildings
* High strength and stability – not easy to deform
* Easy installation – can be cut to size for walls, roofs, and floors
