aluminium sandwich duct System

Pipes: Common types include aluminum foil polyurethane sandwich ducts, which use foam materials such as polyurethane as the core, with aluminum foil or aluminum sheets laminated on both sides.

Fittings: These include flanges, profiles, and other components used for pipe connection and installation.

Tools and Equipment: Such as manual cutting tools and manual bending machines, which are used for pipe processing and installation to ensure precision and efficiency during the installation process.

5 Key Advantages of Pre-insulated PU Duct System for Contractors:

For contractors, aluminum sandwich duct systems simplify installation, reduce costs, and improve efficiency. Their core advantages are as follows:

1. Lightweight design reduces load and labor
Far lighter than traditional metal ducts, they are easier to handle and position, reducing the need for heavy-duty support structures. This lowers material costs for brackets and cuts on-site working hours.

2. Simplified assembly for faster installation
Featuring prefabricated modular components, they require little on-site cutting during assembly. With simple connection methods (such as snap joints and adhesive bonding), they eliminate the step of separately wrapping insulation for traditional ducts, significantly shortening installation time.

3. Strong insulation for energy efficiency and compliance
The foam core has a low thermal conductivity of just 0.022 W/(m·K), reducing the risk of condensation and the need for moisture-proof treatments. It meets green standards like LEED, lowers clients' operational costs, and enhances project competitiveness.

4. Durability and corrosion resistance reduce maintenance costs
Aluminum offers strong corrosion resistance (enhanced after treatment), making it suitable for humid or mildly chemical environments. Its rigid structure resists damage, extends service life, reduces later repair or replacement needs, and strengthens reputation.

5. Excellent air tightness for stable system performance
With an air leakage rate only 1/8 that of traditional ducts, it minimizes conditioned air loss and improves system efficiency. It reduces noise transmission, easily meets standards like SMACNA, and avoids rework or compliance risks.
