Appearance and Material
The aluminum Invisible Profile features smooth lines and a simple, regular shape. Crafted from high-quality aluminum alloy, it is lightweight. After anodizing treatment, its surface presents a silvery sheen that is delicate, smooth, and has a metallic texture. Not only is it aesthetically pleasing, but it can also perfectly match PU/PIR air duct panels, enhancing the overall visual harmony. It is an ideal choice for air duct installation.

Core Functions
1. Stable Connection
As an air duct connecting component, it securely joins different PU/PIR air duct segments through bolts and other fasteners, forming a stable ventilation pipeline system. Its rational structural design effectively resists vibrations and stresses generated during air flow, ensuring long-term stable operation of the duct system and preventing loosening or disconnection.
2. High-Efficiency Sealing
The flange features a high-degree of surface flatness. When paired with a specialized sealing rubber strip, it achieves efficient sealing at duct connections. This effectively prevents air leakage, ensuring that air flows precisely along the designed path in both air conditioning systems (for heating/cooling air delivery) and ventilation/smoke exhaust systems. This reduces energy loss and enhances system energy efficiency.
3. Durability and Corrosion Resistance
The aluminum alloy material itself has excellent corrosion resistance. With special surface treatment, it can adapt to various complex environments such as high humidity, acidic, or alkaline conditions, making it less prone to rust or corrosion. This significantly extends its service life in duct systems and reduces maintenance and replacement costs.
Application Advantages
The aluminum alloy flat flange is lightweight, which can reduce the overall weight of the air duct system, lower installation difficulty and transportation costs, and simultaneously decrease the load-bearing pressure on building structures. It can also be customized according to different specifications of PU/PIR air duct panels
FAQs of PIR Foam Pre-insulated Aluminum Duct
Do PIR pre-insulated (PI) ducts require additional insulation after installation?
No. Unlike traditional steel ducts (which need separate insulation layers like fiberglass), PIR pre-insulated panels are factory-insulated with integrated facing. This eliminates the need for secondary insulation work, saving time and labor.
In which scenarios is PIR pre - insulated duct sheet suitable?
It is widely used in commercial buildings such as offices, shopping malls, and hotels, as well as in residential complexes, industrial facilities, healthcare and food processing facilities, and cold storage and refrigeration systems.
How is PIR pre - insulated duct sheet packaged?
-It is usually packaged in plastic film or cartons, with 10 sheets per package.
How to maintain PIR pre-insulated (PI) ducts?
Maintenance is minimal. Regular inspections for joint tightness (to prevent air leakage) and surface damage (e.g., punctures in aluminum facing) are recommended. Cleaning the inner surface periodically (with mild detergents) helps maintain airflow efficiency, especially in hygiene-sensitive areas.
