Thanks to its excellent products and quality services, UNT Duct is one of the leading air conditioner duct manufacturers and suppliers in China. Welcome to buy the high quality and customized products from our factory. We will offer you the best service and fast delivery.
Air Conditioner Duct
As a high-performance insulation material, UNT HVAC ducts feature a 20mm thick rigid closed-cell PIR foam core, double-sided laminated with 60/80μm embossed aluminum foil. The aluminum foil is coated with a 2g/㎡ corrosion-resistant epoxy varnish to enhance durability and withstand harsh environments.
This panel delivers outstanding thermal insulation, fire resistance and structural strength, and is widely used in HVAC duct systems to achieve energy efficiency, fire protection and efficient air distribution.
PIR air conditioner ducts are widely adopted for their advantages of light weight, excellent thermal conductivity, neat appearance, easy installation and transportation, as well as low maintenance costs.

FAQs of Air Conditioner 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.
