THERMAL INSULATION
Carbowool Sheets®
The latest in “Fibers”, Carbowool® is revolutionary in the insulated material sector.
This new product is manufactured using a drawing method. Its composition, based on lime, magnesia, and silica, results in an excellent physical and thermal stability up to 1100°C.
Carbowool® products have many applications in the thermal insulation sector and in particular in electric appliances and fire protection.
General characteristics
Carbowool sheet® has exceptional characteristics:
- Excellent thermal and physical stability up to 1100°C
- Low weight, flexibility; and exceptional acoustic absorption properties
- Higher traction resistance thanks to our special fabrication technology
- Carbowool needlework sheet® does not contain any organic binders
Carbowool sheet® is incombustible and is approved for fire protection, cellulosic and hydrocarbon fires.
