Polyurethane (PU) Foam Duct
PU foam duct is a new‑generation, high‑efficiency air distribution solution widely applied in modern HVAC systems. Featuring a rigid polyurethane foam core and aluminum foil facing, it integrates heat insulation, air tightness and structural strength in one panel. With outstanding thermal performance, it effectively reduces energy loss and helps lower building energy consumption. Lightweight and easy to install, it greatly shortens construction period and improves project efficiency.
Its closed‑cell structure ensures excellent moisture resistance and prevents condensation and mold growth. The smooth aluminum surface is hygienic, easy to clean and ideal for hospitals, clean rooms, shopping malls, office buildings and other high‑standard places. Stable in performance and long in service life, PU foam duct represents a green, energy‑saving and reliable choice for high‑quality construction projects.

Advantages of Polyurethane (PU) Foam Pre-Insulated HVAC Ductwork Panel
Saves more energy:
It has great insulation, so your air conditioner doesn't have to work so hard. It can cut energy use by 20%–30%.
Light and easy to install:
Much lighter than traditional metal ducts. No extra insulation work needed, so installation is much faster.
No condensation or mold:
It hardly absorbs water, so it stays dry. No condensation, no mold, and no performance drop over time.
Clean and hygienic:
The smooth aluminum surface doesn't collect dust or bacteria. It's easy to clean, perfect for hospitals, food factories and clean rooms.
Strong and long-lasting:
Tough and not easy to crack or break. The aluminum and foam stay well bonded, so it can last 20–50 years.
Quieter operation:
The foam inside absorbs noise, making the room much quieter than with metal ducts.
