PIR Pre-insulated Duct Foam Board
Polyisocyanurate(PIR) 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 Polyisocyanurate(PIR)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.

Materials and Structural Advantages of PIR Pre-insulated Duct Foam Board
Outstanding thermal insulation performance
The thermal conductivity of PIR foam is approximately 0.018–0.02 W/(m·K), with a closed-cell rate exceeding 95%. Its heat insulation efficiency is significantly superior to PU, rock wool, and glass wool.
High fire safety level
The material is of non-flammable B1 grade. It extinguishes fire on its own when separated from the source of ignition, does not drip when carbonized at high temperatures, and has low smoke and toxicity. It complies with standards such as GB 8624 and EN 13501-1.
Stable and durable structure
The double-sided aluminum foil / metal panels provide strength and protection, making the overall weight light (about 1.4–2.0 kg/㎡), reducing building load; it has good dimensional stability, is not prone to deformation or cracking, and has a lifespan of 15–25 years, reducing maintenance and replacement requirements.
Construction and Installation Efficiency of PIR Pre-insulated Duct Foam Board
Integrated prefabrication, simplified processes
The insulation and the panels are integrated and formed together, eliminating the need for secondary insulation on-site. This saves multiple processes such as iron sheet fabrication, insulation covering, and protective layer installation, reducing the construction period by over 50%.
Convenient processing, strong adaptability
It can be directly cut, bonded, and plugged on-site, without the need for large equipment. Irregular bends, changes in diameter, and three-way connectors can all be flexibly manufactured. It is suitable for complex spaces and narrow areas of ceilings.
Lower labor and construction cost
Lightweight reduces the difficulty of transportation. A single person can operate it, reducing high-altitude work and cross-construction. The overall labor, mechanical, and management costs are significantly better than traditional duct systems.
