Large commercial complexes, cultural and sports venues, and transportation hubs possess extensive ventilation, smoke extraction, and air conditioning duct systems. Duct insulation and noise control are key design considerations, and glass wool products are widely used in ventilation duct insulation and machine room sound absorption projects. Encasing ducts in glass wool panels reduces energy loss during hot and cold air transport, prevents condensation on the duct walls, and absorbs vibration noise from internal airflow, preventing noise from spreading to other functional areas.

In fire-fighting smoke extraction systems, flame-retardant glass wool meets the high-temperature insulation requirements of smoke extraction ducts, ensuring structural stability during fires and maintaining normal smoke emission. In noise-concentrated areas such as air conditioning rooms and fan rooms, glass wool sound-absorbing panels can be used as wall and ceiling sound-absorbing structures, effectively reducing equipment operating noise and meeting noise limits for public buildings. Glass wool is chemically stable, does not easily breed mold, and performs reliably in damp underground spaces and underground parking garage ventilation systems.

The material is easy to install; it can be cut on-site to the duct size, and the matching aluminum foil facing provides moisture protection and heat reflection. As the public's demands for indoor comfort in public buildings continue to rise, energy-saving and noise-reducing design of HVAC systems is receiving increasing attention. Glass wool integrated insulation and sound absorption solutions, which take into account multiple needs such as energy saving, noise reduction, and fire protection, are being implemented in various large-scale public building projects.
