PU Air Conditioning Boards

PU Air Conditioning Boards, also referred to as PU aluminum foil duct board or PU sandwich air duct panel, is a high-performance composite material specially engineered for HVAC heating, ventilation and air conditioning ductwork systems.

The panel features a three-layer bonded composite structure:

Two outer faces: Heavy-duty aluminum foil, available in smooth or embossed finishes

Central core: Rigid polyurethane (PU) foam, serving simultaneously as structural reinforcement and thermal insulation

 

Panel Structure: Silver Alu. / PU Foam / Silver Alu. Sheet
Foam Density: 45kg/M3
Panel Dimension: 3950mm*1200mm*20mm
Alu. Foil: 60 Micron (Embossed)

How does the PU Air Conditioning Boards perform in terms of energy efficiency?

1.This PU pre-insulated duct has excellent thermal insulation performance, effectively blocking heat transfer and minimizing cold/heat loss during air delivery.

 

 

2. Its fully sealed structure ensures superior airtightness, greatly reducing air leakage and avoiding unnecessary energy waste.

 

 

3. Stable insulation effect lowers the operating load of air conditioning and ventilation equipment, helping cut down long-term power consumption remarkably.

 

 

4. It maintains consistent indoor temperature steadily, optimizes overall HVAC operation efficiency, and brings prominent energy-saving benefits for projects.

 

 

5. Compared with traditional insulated duct solutions, it achieves higher energy utilization rate and saves more operational costs year-round.

PU Air Conditioning Boards represents a premium HVAC ventilation solution, combining innovative technology, stringent performance standards and sustainable design. It stands out for diverse engineering projects thanks to the key advantages below:

1. Superior Energy Efficiency with Advanced Insulation

Premium Thermal Insulation & High Energy Efficiency Built with patented Hydrotec water-blown PU foam core, the panel achieves thermal conductivity as low as 0.020 W/(m·K). 20mm-thick panels match the insulation effect of 30mm traditional rubber insulation, curbing heat loss and cutting HVAC power consumption. A ≥95% closed-cell structure (ISO 4590) prevents moisture ingress and condensation, guaranteeing stable insulation performance from -40℃ to 80℃ even in humid climates. It reduces long-term system energy costs by 20–30% versus conventional ductwork.

2. Industry-Leading Airtightness & Cleanliness

Certified Class C airtightness to UNI EN 13403, the duct maintains zero leakage under ±2000Pa air pressure. The exclusive hidden flange design stops longitudinal leakage and optimizes sealing at cross joints. The inner food-grade antibacterial aluminium foil features a smooth surface to resist dust, mould and bacteria, easy to sanitize for hospitals, pharma labs and food factories. Nano self-cleaning coated panels are available as an upgraded option.

3. Unmatched Durability & Long Lifespan

With flexural strength of 2MPa and compressive strength of 0.25MPa, the panel delivers solid mechanical performance. Anti-corrosion polyester coating options support harsh industrial scenarios. Its lightweight rigid structure offers good seismic resistance. Free from rust and scaling issues seen in galvanized ducts, the product needs minimal maintenance and can serve up to 50 years, far longer than the 10–15-year lifespan of traditional metal ducts.

4. Effortless Installation & Project Flexibility

Much lighter than galvanized ducts, it lowers building load and speeds up installation by 40–60%. Both factory prefabrication and on-site assembly are supported, customizable into multiple shapes for narrow spaces. Our full product range includes indoor/outdoor grades, slim low-pressure panels and high-cleanliness variants, ideal for new builds, retrofits, data centres and CDC projects.

5. Eco-Friendly & Safety Compliance

Water foaming technology eliminates CFC/HCFC/HFC, with ODP=0 and GWP=0, complying with EU RoHS and green building standards. Class B fire rating to EN 13501-1; low smoke toxicity (FED/FEC ＜0.3) ensures safety in emergency fire situations.

6. Long-Term Economic Value

Despite slightly higher initial cost, the panel brings outstanding economic returns: 20+ years service span, 20–30% reduced energy expenditure and negligible maintenance fees. Lower transport cost and faster construction further cut total project investment for commercial & industrial HVAC applications.
