We are top manufacturer of Centrifugal Glass Wool products, including Glass Wool Blanket/Felt/Roll, Glass Wool Blanket Board. Our products are with CE certificate, and have been exported to USA, UK, Germany, Poland, etc.
The Centrifugal Glass Wool Blanket/Felt/Roll and Board are excellent heat preservation and sound absorption material for steel structure, ceiling, outer wall, partition wall, train compartment, air duct, etc. It features:
1. Excellent for heat preservation, thermal insulation, sound absorption;
2. Non-combustible, nontoxic, and resistant to corrosion;
3. Low thermal conductivity, stable chemical property, low moisture rate and good hydrophobicity;
4. Low weight by volume, good rebound elasticity;
5. Low constructional cost, short cycle of works, non-stimulation to the skin.
