PIR Duct Foam Sheet
PIR Duct Foam Sheet is a high-performance pre-insulated HVAC panel with rigid polyisocyanurate foam core and double-sided aluminum foil/metal facing. Featuring ultra-low thermal conductivity (0.018–0.022 W/(m·K)), excellent B1-class fire resistance, closed-cell structure, and outstanding moisture-proof performance. Lightweight, high-strength, airtight, and easy to fabricate and install, it greatly reduces air leakage and energy loss. Widely used in commercial buildings, hospitals, shopping malls, clean rooms, and industrial HVAC duct systems for efficient energy saving and long-term stable operation.

Energy-saving and Air-tightness Advantages of PIR Duct Foam Sheet
The product adopts prefabricated integrated insulation, and the on-site connection and sealing are reliable. The air leakage rate of the duct is much lower than that of traditional iron sheet ducts, significantly reducing the loss of cooling / heating capacity.
The closed-cell structure prevents water vapor penetration, avoiding the deterioration of the insulation layer due to moisture absorption, and maintaining stable insulation performance over the long term.
In the central air conditioning system, it can significantly reduce the load of the unit, shorten the operation time, and lower electricity costs. The energy-saving benefits throughout the entire life cycle are outstanding, meeting the requirements of green buildings and carbon neutrality.
Construction and Maintenance of PIR Duct Foam Sheet
The panels can be directly cut, bonded, and assembled without the need for secondary insulation on-site. The process is simplified, the construction period is shortened, and the labor and material costs are reduced.
The self-weight is light, reducing the lifting and structural loads, making it suitable for renovation projects.
The system has good air tightness, smooth inner walls, low wind resistance, and low energy consumption of the fan; the metal surface layer is corrosion-resistant, easy to clean, and more suitable for purification facilities.
The later maintenance is simple, without glass wool dust pollution, and the maintenance cost is lower.
Competitive Comparison and Core Advantages of PIR Duct Foam Sheet
Compared with materials such as glass wool, XPS, and PU, PIR has a more balanced overall performance in terms of insulation, fire resistance, moisture resistance, and durability: its insulation performance is superior to XPS, its fire resistance is far better than PU, and its moisture resistance and lifespan are better than glass wool.
The integrated prefabrication solves the traditional construction pain points, balances performance and cost, has strong competitiveness in the high-end ventilation and insulation market, and is an upgraded solution to replace traditional ducts.
The VOC emissions during production and use are low, and there is no fiber dust. It complies with indoor environmental protection standards. The flame-retardant and low-smoke properties enhance fire safety and reduce smoke hazards. The material is recyclable, with a service life of 15-20 years, reducing the frequency of replacement and lowering resource consumption and solid waste generation.
