Polyurethane (PU) Foam Pre-Insulated Aluminum Duct Boards
PU Pre-insulated Duct Boards are composed of PU insulation foam with aluminum foil or aluminum sheet on both sides. They are energy-efficient and environmentally friendly, and are widely applied in HVAC duct systems.
Compared with traditional galvanized iron (steel metal) ductwork, Pre-insulated HVAC Duct Boards offer a high-performance, lightweight and robust system. They only require a single-step installation process. These pre-insulated ducts have become increasingly popular around the world. Depending on different application scenarios or project requirements, the surface covering of the PU panel can be a 60-micron aluminum foil, an 200-micron aluminum sheet, or a pre-painted galvanized iron (GI) sheet.
Why choose Aluminum Foil Polyurethane (PU) Pre-Insulated Duct Board
The UNTDuct PU System is not just made of pre-insulated aluminium panels. It also includes essential accessories, tools, and technical know-how for masterful construction and installation. The UNTDuct Panel is a sandwich panel, featuring an external aluminum sheet that encases a closed-cell insulating material-Polyurethane (PU) foam with a density of 50 kg/m³.
The UNTDuct PU pre-insulated panel enables the creation of extremely high-quality ducting, which is directly attributed to the excellent insulation properties of the PU foam. Additionally, the UNTDuct PU pre-insulated panel offers outstanding internal air quality, a superior external finish, long-lasting material properties, and is lightweight, making it easy to transport, handle, and install.
Ducting systems built with UNTDuct PU pre-insulated panels can be installed either inside or outside a building, and they can be either visible or hidden by a false ceiling, suitable for both residential and commercial applications.
Moreover, UNTDuct PU pre-insulated panels are an excellent choice for various industry sectors such as food processing, electronics, pharmaceuticals, hospitals, and medical centers. These sectors require a high level of quality and hygiene, and the UNTDuct PU pre-insulated panels meet those requirements.
Owing to its exceptional products and top - notch quality services, UNT Duct has firmly established itself as one of the preeminent manufacturers and suppliers of UNTDuct Polyurethane (PU) foam insulation air duct panel composites with aluminum foil in China.

Advantages of Polyurethane (PU) Pre-Insulated Duct Boards:
High thermal insulation with a thermal conductivity value of 0.022w/m.k allows for maximum exploitation of
air handling unit capacity, increasing efficiency and reducing operating costs.
Extremely light weight compared to sheet metal ducts allows a reduction of weight on the structures, supporting points, workmanship costs and materials necessary for the installation.
Air-tightness of UNTDuct PU System is eight times more than traditional ducts
The use of aluminum for the internal surfaces of the ducts ensures hygiene and cleanliness, it has a beautiful appearance and is suitable for the food industry
The sandwich structure (aluminum – insulating material – aluminum) guarantees a good acoustic behavior. Vibration and reverberation are stopped by the insulating material, contributing to a higher comfort in the environment where UNTDuct is installed
It is easy to manufacture ducts at job site with considerable advantages on transport costs.
UNTDuct PU Panels have a low participation in fire, do not drop and smokes have a reduced opacity and toxicity. UNTDuct PU Panels is in conformity with the requirements of the most restrictive international regulations.
The outer aluminum coating coupled with the insulating material provides sturdiness, rigidity and good resistance to corrosion, erosion and deformation even in special applications.
The UNTDuct PU Foam Pre-insulated Aluminum Duct Board can be utilized to produce extremely high-quality ducting. This is directly attributable to the remarkable insulation properties of the PIR foam. The UNTDuct PU pre-insulated panel additionally offers excellent internal air quality, a superior external finish, long-lasting material characteristics, and is lightweight, making it easy to transport, handle, and install.
