Fiberglass Air Duct of Sustainable Grade for Noise Reduction & Airflow Control

Fiberglass Air Duct of Sustainable Grade for Noise Reduction & Airflow Control. Adopt flexible ultra fine fiberglass structure to fit various curved ventilation duct surfaces closely. Optimized porous fiber layout delivers enhanced acoustic insulation and noise control performance. Stable low thermal conductivity locks internal air temperature and cuts building ventilation energy loss. Reach A1 non combustible fire grade to meet strict HVAC pipeline fire safety specifications. Lightweight flexible texture supports free cutting and wrapping to simplify on site duct construction. Excellent moisture resistance maintains stable acoustic and thermal performance in humid air duct environments. Strong anti aging and oxidation capacity adapts to long term continuous ventilation pipeline operation. Customizable thickness density and width to match different ventilation duct engineering technical standards.
