PU Air Conditioning Duct Panels
Manufactured with high-performance PU foam as the core material, PU Air Conditioning Duct Panels are lightweight composite products. They integrate excellent thermal insulation, structural rigidity and certified fire resistance into one integrated unit, and are widely used in various HVAC construction projects.
This modular all-in-one duct system effectively cuts down energy loss of the whole system, speeds up on-site installation, and maintains consistent ventilation performance throughout long-term service.

Construction Efficiency and Cost of PU Air Conditioning Duct Panels
Integrated prefabricated panels allow one-stage cutting and assembly, effectively shortening construction schedules:
Labor Efficiency Metrics When fabricating an equal area of ductwork, traditional galvanized steel duct systems involve subsequent external insulation procedures, with a daily output of 18 m² per worker. PIR pre-insulated panels are assembled directly on-site, reaching a daily output of 30 m² per worker. Accordingly, installation time is reduced by 40%–60%, and labour costs drop by 45%.
Full-Lifecycle Cost Breakdown Despite higher unit costs for the panels compared to galvanized steel sheets, expenses for secondary insulation, damp-proof membranes and abundant hangers are eliminated. The total cost of the complete duct system is equivalent or up to 8% lower.
Transportation Merits Foldable packaging maximises cargo utilisation, lifting vehicle loading volume by 2.3 times and cutting domestic and marine logistics expenditure by 50%. Such logistics advantages stand out for overseas projects executed under DAP Incoterms.
Material Performance of PU Air Conditioning Duct Panels
From a structural perspective, the closed-cell rate of PU boards can reach over 90%, with independent and non-connected pores and a water absorption rate of ≤ 3%. The waterproof and moisture-proof ability is extremely strong.
In warm ventilation ducts and cold storage environments with high humidity and frequent condensation water, there will be no insulation failure or board deformation due to water absorption. At the same time, its density is typically within the range of 35 - 50 kg/m³, balancing strength and lightweight, with a compressive strength of ≥ 150 kPa, capable of withstanding regular foot and external compression, and not prone to cracking or powdering.
In terms of flame retardancy, by adjusting the formula, it can reach the B1 level of non-flammable standard. During combustion, there is no molten dripping and low smoke density, which is suitable for building fire protection regulations, and the comprehensive safety performance is superior to some organic insulation boards.
