P3 Duct Foam Panel
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.

Thermal insulation and performance of P3 Duct Foam Panel
The core advantage is the extremely low thermal conductivity (0.020W/m・K). The 20.5mm thick P3 board has an insulation effect equivalent to 40mm glass wool or 30mm plastic insulation layer.
Compared with traditional galvanized iron sheet ducts (thermal conductivity 0.038W/m・K), it can reduce the energy consumption of the HVAC system by 20%-30%. Taking a 10,000㎡ commercial building as an example, the annual air conditioning energy consumption can be reduced by approximately 80,000 kWh, equivalent to electricity cost of about 64,000 yuan.
The closed-cell structure has a water absorption rate of ≤0.36%, preventing moisture-induced failure and maintaining long-term insulation stability far exceeding traditional materials.
The composite structure combines insulation, structural strength, and protective functions, and differs from the traditional iron sheet duct's "metal + outer insulation layer" separate structure.
Physical and Installation Performance of P3 Duct Foam Panel
Lightweight and High Strength: The surface density is only 1.5 kg/m², which is 70%-75% lighter than metal ducts, significantly reducing the load on the building structure and the installation cost. The compressive strength reaches 202 kPa, capable of withstanding a wind pressure of 1000 Pa, meeting the requirements of 2500mm large-sized ducts.
High Air Tightness: Using built-in flanges for bonding, there are no nail gaps, with a leakage rate of less than 2%, which is 1/8 of that of traditional ducts, significantly improving the supply efficiency.
Efficient Installation: It can be cut and bonded on-site, without the need for special equipment, reducing the installation cycle by 50% and lowering labor costs by 30%.
The inner surface is smooth and self-cleaning with anti-bacterial treatment, which can inhibit the growth of bacteria and is suitable for high-cleanliness environments such as hospitals and food factories.
Fire safety performance of P3 Duct Foam Panel
The fire resistance rating of the P3 board reaches EN 13501-1 B1 level (non-flammable), and the aluminum foil protective layer is A-level non-combustible material.
During a fire, the surface carbonizes to form a flame-retardant layer, without any molten droplets, and the smoke toxicity level T ≤ 6.4 (in accordance with the NES713 standard), with no toxic smoke spreading.
The ISO 9705 corner test shows that within 100 seconds, the fire source is reduced by 1/3, and the flame is confined to the area affected by the fire, providing a safety guarantee for the evacuation of personnel.
Although the unit cost of the material is higher than that of traditional iron sheets, the total life cycle cost is lower: installation cost is reduced by 30%, energy consumption cost is reduced by 20%-30%, maintenance cost is almost zero, and the replacement cycle is extended by 3 times.
