Polyurethane Air Duct Foam Board

Thanks to its excellent products and quality services, UNT Duct is one of the leading polyurethane air duct foam board manufacturers and suppliers in China. Welcome to buy the high quality and customized products from our factory. We will offer you the best service and fast delivery.

 

Polyurethane (PU) Foam Pre-Insulated HVAC Ductwork Panel is a high-performance, all-in-one solution designed for modern heating, ventilation, and air conditioning (HVAC) systems. Built with a precision-engineered sandwich structure, it features a dense polyurethane (PU) foam core-celebrated for its exceptional thermal insulation properties-sandwiched between two protective layers of corrosion-resistant aluminum foil. This factory-prefabricated panel merges insulation, structural strength, and airtightness into a single component, eliminating the need for separate insulation installation and streamlining ductwork setup in diverse buildings.

Superior Insulation and Thermal Insulation Properties
The product has a closed-cell rate of over 95%, with a thermal conductivity as low as 0.022W/(m・K), which is far superior to traditional insulation materials such as extruded polystyrene boards and polystyrene boards. This can significantly reduce the heat/cold loss of air ducts; the closed-cell structure can also prevent water vapor from penetrating and avoid the failure of the insulation layer due to condensation, ensuring stable long-term insulation effect and adaptability to different temperature conditions, including high and low temperatures.
Safe, Flame Retardant and Environmentally Friendly
The product's combustion performance reaches the B1 level of non-flammable standard, with no dripping after combustion and compliance with building fire protection regulations; it uses zero ODP, low GWP non-halogenated foaming agents, with VOCs release meeting standards, without formaldehyde and other harmful substances. At the same time, it aligns with the national "carbon neutrality" strategy, making it an environmentally friendly insulation material.
High Air Tightness and Anti-Cold Bridge
The splicing area is bonded with the same-source polyurethane foam adhesive, with the board gap being ≤ 2mm and sealed treatment applied. The air tightness is 8 times that of traditional iron sheet air ducts, completely solving the problem of air leakage; paired with the bridge insulation flange, it effectively blocks the formation of cold bridges, avoiding condensation and corrosion on the outer wall of the air duct.
Lightweight, High Strength and Additional Functions
The core material density is approximately 50-55kg/m³, with the overall weight being only 1/3 of that of traditional iron sheet air ducts, significantly reducing the load of the building structure; at the same time, polyurethane foam can absorb vibrations and echoes, combined with the embossed aluminum foil surface layer, it can replace simple mufflers and has both sound absorption and noise reduction effects. Some modified models also have antibacterial and mold-resistant properties, suitable for food and medical fields.

Installation is efficient, and the construction period is significantly shortened.
The product is lightweight and easy to transport and cut. No heavy construction equipment is required. The connection is achieved through 45° angle bonding or "H" shape reinforcement strips, and the construction process is simple. Compared to the traditional iron sheet duct + secondary insulation construction method, the construction period can be shortened to 1/5, significantly improving the construction efficiency.

Multiple specifications are compatible, and the application scenarios are wide.
The surface layer can be customized with materials such as 60μm aluminum foil and 180μm color steel plates, with thickness ranging from 10 to 40mm. It can meet the HVAC system requirements of different scenarios in commercial buildings, industrial plants, data centers, and rail transit, and can be used for indoor exposed or concealed duct installation, or can be adapted to the protection requirements of outdoor ducts.

 

Reduce long-term operational energy consumption
Excellent insulation and airtightness can enhance the efficiency of the air conditioning system, reduce energy waste caused by heat/cold loss, and achieve significant energy-saving effects during long-term operation.

Save overall project costs
On one hand, it eliminates the costs of secondary insulation and soundproofing materials and labor. On the other hand, its lightweight nature reduces the investment in supports, hangers, and load-bearing structures; at the same time, the construction period is shortened, which can lower indirect costs such as project management and labor, and the overall project cost is 10%-15% lower than the traditional solution.

Long lifespan and maintenance-free, short return period
The product is treated with anti-corrosion and acid-base resistance, and has a lifespan of over 20 years under normal conditions, without the need for frequent maintenance or replacement.

Mainstream scene demand is rigid
Currently, the 30-50mm medium-density models occupy 65% of the market share, meeting the core heating and ventilation needs of commercial buildings; high-density (≥45kg/m³) models are experiencing annual growth in demand in heavy-load scenarios such as data centers and pharmaceutical workshops. Antibacterial, mold-resistant, and anti-static modified models are penetrating the food and semiconductor industries, with a compound annual growth rate of 15.6%.

Industry is upgrading towards higher-end and greener standards
With stricter environmental regulations, the proportion of non-chlorofluorocarbon foaming products has reached 78%. In the future, A2-level high fire resistance and low smoke density composite panels will become the focus of research and development; at the same time, the industry is transforming from simple material manufacturing to system solutions. Digital cutting and BIM model support will become the core of product value-added, and industry concentration will continue to increase.
