Fiberglass ducts not only provide thermal insulation, but their internal fiber structure also effectively absorbs airflow noise, making them widely used in buildings with high acoustic requirements, such as shopping malls, hotels, and office buildings. Airflow within the duct generates vibration and noise; the fiberglass material can reduce this sound energy to a certain extent, making the system operate more quietly.

Compared to traditional metal ducts, which require additional sound-absorbing materials, fiberglass ducts possess inherent sound-absorbing properties, reducing construction steps and improving overall system efficiency. Furthermore, their lightweight nature facilitates transportation and on-site assembly, enabling rapid construction of large-scale projects.

In actual engineering projects, it is essential to ensure that duct connections are smooth and sealed, and that duct dimensions are rationally designed according to airflow and pressure requirements. For projects with high noise control requirements, fiberglass ducts remain a preferred material that balances thermal insulation and noise reduction.
