FAQs of PUR Foam Pre-insulated Duct Panel
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.

PUR Foam Pre-insulated Duct Panel
The heart of this duct panel lies in its rigid PU core. Renowned for its exceptional thermal resistance, the PU foam significantly reduces heat transfer, minimizing energy losses during the transportation of conditioned air.
This translates into substantial energy savings, making it an eco-friendly and cost-effective choice for schools aiming to cut down on utility bills while reducing their carbon footprint. In large educational facilities where HVAC systems operate continuously, these savings accumulate over time, providing a significant financial advantage for school administrators.
