Glass Wool Board

HN glass wool board is a plate-like material made by melting quartz sand and other raw materials at high temperature, then centrifugally spraying them into fibers (with a diameter of ≤ 6 μm), and subjecting them to pressure curing. The surface can be adhered with PVC film, aluminum foil, etc., and it has the characteristics of low density (20 – 100 kg/m³) and low thermal conductivity (0.032 – 0.042 W/(m·K)). It is a Class A non-combustible material and safe usage temperature range of -120℃ to 400℃.

HUANA Glass Wool material is certified under UL, CE, and ASTM standards, ensuring global compliance for safety and quality. It is available with Aluminum Foil (FSK) or Polypropylene (WMP) facing.
