PIR Air Conditional Duct

PIR Air Conditional Duct serve as a premium high-performance solution for modern HVAC systems. Built as an integrated sandwich composite with aluminium foil surfaces and rigid PIR foam core, they outperform traditional galvanised steel ducts needing field insulation. Widely adopted across numerous projects, they are the preferred choice for hotels, office buildings, airports, hospitals and other commercial & public constructions.

This integrated design merges duct structure, thermal insulation and vapour barrier functions within a single lightweight panel, streamlining the whole system installation.

Typical technical specifications of the panels are listed as follows:

Core Density: ~53 kg/m³

Thermal Conductivity: ≤ 0.022 W/m·K (providing excellent insulation)

Standard Thickness: 10-40mm

Common Sizes: 1200mm width * 4000mm length

Fire Rating: Meets international standards like BS 476 Class 0 and ASTM E84 Class A due to the flame-retardant PIR core

Outstanding Thermal Insulation & Ultra Energy Saving of PIR Air Conditional Duct

Excellent Thermal Insulation and Significant Energy Savings

PIR Air Conditional Duct features remarkable thermal insulation as one of its core advantages.

Boasting ultra-low thermal conductivity of 0.018–0.022 W/(m·K), it surpasses glass wool, XPS and standard PU foam. A 20 mm PIR panel provides the same insulating effect as 50 mm glass wool.

Its closed-cell fraction exceeds 95%, effectively preventing thermal bridging and limiting heat transfer of conditioned air.

This enables a 20–30% reduction in HVAC power demand, greatly cutting ongoing electricity operational costs for commercial facilities.

Thanks to its integrated insulation structure, extra external wrapping work necessary for metal duct systems can be omitted.

Service Life, Environmental Protection and Hygiene of PIR Air Conditional Duct

Durability Data

Stable cyclic macromolecular PIR structure limits thermal conductivity deterioration to ≤5% over 25 years, with a service life of 20–25 years. Galvanized steel ducts corrode and leak within 5–8 years; rock wool pulverises and fails in 5 years. Life-cycle replacement costs drop by 70%.

Environmental Performance

Zero formaldehyde, benzene emissions and asbestos-free. Production foaming loss is only 3%, and waste scraps are recyclable. Eligible for LEED and China Three-Star Green Building certification credits.

Cleanroom Hygiene Performance

Double-sided smooth antibacterial aluminium foil lowers airflow resistance by 12% and prevents dust and mould build-up. Suitable for food factories and hospital operating room purification ventilation. No extra antibacterial lining needed, with zero extra consumable costs for clean projects.
