Polyurethane Ducting Panel

Polyurethane Ducting Panel, alternatively designated PU aluminum foil duct panel and PU sandwich duct panel, is a high-spec composite material intended for HVAC (Heating, Ventilation and Air Conditioning) air duct applications.

The product adopts a trilaminar laminated structure composed of:

Dual outer facings: High-tensile aluminum foil, supplied in plain or embossed variants

Internal core substrate: Rigid polyurethane (PU) foam, functioning as structural backing and thermal insulating medium

Structure: Silver Aluminum/ PU Foam/ Silver Aluminum
Size: 3950*1200*20mm
Foam Density: 48kg/m3
Aluminum Thickness: 0.06mm or 0.08mm
Aluminum Color: Silver and Black
Packing: 10 sheets/ package
Loading Capacity: 710 sheets/ 40'HQ (packed with plastic bags)
660 sheets/ 40'HQ (packed with cardboard box)

The "lightweight revolution" of Polyurethane Ducting Panel

In the HVAC sector, the PAL prefabricated insulated duct system transcends a single product category. It delivers a revolutionary construction mindset, shifting the workflow from field fabrication to modular assembly. Constructed with PIR (polyisocyanurate) or phenolic foam core and dual-side aluminium foil cladding, the system distinguishes itself from traditional galvanized steel ductwork in material characteristics and construction logic.

Conventional duct projects demand separate shipment of galvanized steel panels, rock wool/fiberglass insulation, adhesives and auxiliary components. Such materials are bulky and susceptible to abrasion and damage.

Polyurethane Ducting Panel achieve a density of roughly 50 kg/m³, and completed ducts weigh only 15% of comparable galvanized steel alternatives.

Economically for logistics, unit-area transport costs are reduced, while the space required for on-site material storage decreases by over 60%.

Comprehensive Breakthroughs in Performance and Cost

The Polyurethane Ducting Panel boasts competitive advantages across multiple dimensions. Featuring low thermal conductivity, polyurethane foam offers excellent thermal insulation and energy efficiency, cutting air conditioning energy consumption by 15%-20% in large commercial buildings compared with traditional ductwork.

Much lighter than galvanized iron ducts, a 20mm-thick PU duct weighs approximately 5kg per square meter - only one-third of equivalent GI ductwork, facilitating transport and reducing building loads. Its closed-cell structure and dedicated sealing technology greatly reduce air leakage to enhance ventilation efficiency.

Made of flame-retardant PU, the system meets fire safety criteria and restrains fire spread. The aluminum foil outer layer and waterproof polyurethane prevent moisture ingress and mold growth to sustain air cleanliness.

Additionally, PU foam provides sound absorption to reduce ventilation noise. With tidy metallic surfaces compatible with various architectural styles, no extra decoration is required.
