PIR Foam Air Ductwork
PIR Foam Air Ductwork is a premium lightweight composite panel structured with high-performance rigid foam insulation as the core material, paired with durable protective surface layers.
This integrated composite structure endows the duct panels with excellent overall performance, overcoming the defects of heavy weight, poor heat insulation and easy corrosion of traditional metal ducts.
Perfectly integrating efficient thermal insulation, stable mechanical structural strength and reliable fireproof performance, our PIR duct panels are versatile and adaptable to a full range of HVAC engineering scenarios, including commercial buildings, industrial plants, cold storage facilities, public infrastructure and other ventilation and air-conditioning systems.
In practical application, the ductwork greatly reduces overall energy loss of the HVAC system, delivers convenient, labor-saving and fast on-site assembly construction, and can sustain stable, efficient and long-lasting ventilation operation effect in various complex operating environments, which effectively improves the overall operating efficiency of the building ventilation system.

How does the sandwich structure of PIR Foam Air Ductwork improve thermal insulation?

The sandwich structure of PIR Foam Air Ductwork achieves superior thermal insulation mainly through the following mechanisms:
1. The core layer adopts high-density rigid PIR foam material, which features extremely low thermal conductivity. It can effectively block heat conduction and greatly reduce heat transfer between inside and outside the duct.
2. Double-sided aluminum foil composite panels serve as outer protective layers. They reflect radiant heat and prevent hot and cold air penetration, further cutting off heat exchange.
3. The integrated seamless sandwich design avoids air gaps and thermal bridges inside the duct. It eliminates heat loss caused by gap ventilation, ensuring stable and long-lasting heat preservation effect.
4. This compact composite structure concentrates excellent insulation performance in one panel, effectively lowering air conditioning energy consumption and optimizing the overall operating efficiency of HVAC systems.
