THERMAL INSULATION
Carbowool Papers®
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.
