25-Year Lifespan? Meet the Aluminum Foil PU Duct

The Role of Aluminum Foil in Central Air Conditioning Duct Systems

With the rapid development of central air conditioning across industrial, commercial, and residential buildings, the demand for aluminum foil composite air ducts has grown significantly. Among the most widely used solutions today are aluminum foil phenolic duct panels and aluminum foil polyurethane (PU) duct panels.

Aluminum Foil Phenolic Rigid Foam Ductwork

These ducts are made from Phenolic Rigid Foam Ductwork laminated with high-temperature resistant aluminum foil on both sides. The foil, typically 80μm thick, is coated with a fluorocarbon resin primer, while the core is made of rigid phenolic foam. This structure makes it ideal for HVAC duct applications.

Key Benefits:

• Excellent thermal insulation – reduces energy loss in HVAC systems by less than 2%.
• Strong sound absorption – lowers noise by 5–10 dB compared to traditional ducts.
• Lightweight (approx. 1.4 kg/m) – reduces building load and simplifies installation.
• Long service life – 20+ years, matching the lifespan of AC units.
• High recyclability – up to 70%.
• Hygienic air delivery – the sealed aluminum foil surface prevents condensation and corrosion.
• Cost-efficient: Aluminum foil phenolic air ducts can cut overall investment by up to 25%.

They are widely used in supermarkets, factories, airports, offices, banks, cleanrooms, and other large-scale HVAC projects.

Aluminum Foil PU Rigid Foam Ductwork

Made from aluminum foil PU Rigid Foam Ductwork, these panels feature embossed aluminum foil laminated to a fire-retardant PU foam core. The outer foil layer includes an OP coating resistant to acids and moisture, while the inner foil is bonded with a resin adhesive to ensure strong adhesion to the foam core.

จุดเด่นของผลิตภัณฑ์:

• Lightweight and easy to handle.
• Superior insulation and energy efficiency.
• Strong compression resistance and flexible for shaping.
• Excellent sealing properties.
• Flame-retardant and safe – non-combustible core.
• Long lifespan – up to 25 years.
• Economical – lowers installation and operational costs.

Thanks to these advantages, aluminum foil PU duct panels are now widely adopted in HVAC duct systems, data center flooring, and building wall insulation—especially in central air conditioning applications.
