PID HVAC Ductwork
PID HVAC Ductwork are lightweight composite panels made with high-performance foam insulation as the core material.
Combining great thermal insulation, solid structural stability and reliable fire resistance, these duct panels are widely used in all kinds of HVAC projects.
They effectively reduce energy loss, allow quick and easy on-site installation, and maintain stable ventilation performance during long-term operation.

What is the expected lifespan of the PID HVAC Ductwork?
Standard lifespan: more than 20 years (indoor, commercial/normal industrial, proper installation & maintenance).
Conservative range: 15–20 years (humid coastal areas, moderate industrial exposure).
Core durability factors
Closed-cell PU foam core: resists moisture, mold, and degradation.
Double-sided aluminum foil: corrosion-resistant, non-combustible, and aging-resistant.
Fully sealed joints : minimal air leakage, stable thermal performance over time.
Compared with traditional ducts
GI ducts (with insulation): 5–10 years (prone to rust, insulation failure).
Flexible ducts: 10–15 years.
PID HVAC Ductwork: More than 20 years.
Maintenance tip Annual visual inspection and cleaning of the outer surface keep it performing well for 20+ years.
Advantages of PID HVAC Ductwork
As a professional manufacturer serving European and Asian markets, we deliver high-performance PIR ventilation ductwork solutions for global HVAC projects.
Exceptional Thermal Efficiency
Featuring an ultra-low thermal conductivity coefficient ranging from 0.018 to 0.022 W/m·K, our PIR duct panels effectively minimize heat transfer and cut HVAC system energy consumption by over 20%. The product maintains outstanding temperature stability under extreme working environments, with a wide temperature resistance range from -196°C to 140°C, ensuring consistent operational performance in diverse climatic conditions.
Superior Fire Safety Performance
Complying with GB 8624 standard, our ductwork achieves Class B1 fire resistance rating, equipped with self-extinguishing capability and ultra-low smoke toxicity. During combustion, the panel surface forms a dense protective char layer that effectively inhibits flame propagation and prevents fire spread, delivering reliable fire safety assurance for building ventilation systems.
Lightweight Structure & High-efficiency Installation
With a lightweight density of merely 1.4 kg/m², the PIR duct panels greatly reduce building structural load and simplify manual handling procedures. Adopting a standardized modular design, the product achieves 50% higher on-site installation efficiency than conventional metal ducts, significantly shortening project construction cycles and lowering overall engineering costs.
