PIR ALU Duct Panel

PIR ALU DUCT PANEL, short for Polyisocyanurate Aluminum Duct Panel, is a high-performance pre-insulated composite panel specifically engineered for the fabrication of air ducts in HVAC (Heating, Ventilation, and Air Conditioning) systems. Unlike traditional metal ducts that require separate insulation layers, this integrated panel combines structural support, thermal insulation, vapor barrier, and airtightness in one single product, making it a preferred choice for modern building projects-ranging from small residential complexes to large-scale commercial and industrial facilities. Its design focuses on energy efficiency, ease of installation, and long-term durability, addressing the key pain points of traditional duct systems such as high energy loss, complex installation, and poor moisture resistance.

PIR ALU DUCT PANEL adopts a three-layer composite structure, with each layer serving a specific functional purpose, ensuring the overall performance of the panel. The layers are firmly bonded through advanced lamination technology, ensuring no delamination during transportation, installation, or long-term use.
