fiber glass wool

Advantage
1. Unique technology; Rebound degree after compressive packing is up to 99.2%.
2. Soft and long glass fibers can maximally lessen flying catkins in the construction.
3. Sound absorption and noise reduction; It can effectively prevent sound from spreading.
4. Grade A1 incombustible materials.
5. Easy for construction; cutting at will.
6. Antisepsis, ageing resistance, and anticorrosion, ensuring a healthy environment.
7. Low moisture absorption; Stable physical properties.
