Why Choose PIR foam Aluminium Foil Duct?
Thermal Insulation, Low Smoke & Low Toxicity
PI foam has built-in flame retardancy with LOI above 34%, much higher than ordinary flame-resistant materials.
Premium Acoustic and Thermal Insulation
Boasting an open-cell structure (open-cell ratio up to 99%), it delivers strong sound absorption with an NRC of up to 0.54 (125–4000 Hz), lowering HVAC airflow and equipment noise. Its thermal conductivity is below 0.022 W/(m·K), providing lightweight and reliable thermal insulation.
Ultra-Low Outgassing & Great Chemical Stability
Its minimal outgassing avoids contamination to precision instruments under vacuum, making it ideal for aerospace and semiconductor cleanrooms. It withstands weak acids, weak alkalis and common oils including 93# gasoline with stable chemical performance.
Advantages of UNTDuct PIR ALU Pre-insulated Duct:
1. Enhanced Thermal Efficiency
Featuring ultra-low thermal conductivity, UNTDuct delivers outstanding thermal performance, effectively reducing HVAC heat loss and cutting long-term energy consumption.
2. Fast & Streamlined Installation
Lightweight low-density structure simplifies handling and assembly, greatly shortening construction time and lowering overall labor costs.
3. Eco-Friendly & Zero ODP Materials
CFC-free foam formulation eliminates ozone-depleting substances, supporting green building standards and sustainable environmental development.
4. Excellent Airtight & Leak-Proof Performance
Reliable hermetic sealing minimizes air leakage, stabilizing HVAC operation and maximizing overall system efficiency.
5. Corrosion Resistant & Neat Appearance
Double-sided aluminum reinforcement provides strong anti-corrosion and hygienic performance, while maintaining a clean, premium on-site appearance.
6. Waterproof & Sound Insulation
High-density closed-cell foam delivers excellent waterproof protection and effective sound damping, creating a quieter, moisture-proof indoor environment.
7. Long-Term Cost Efficiency
Easy fabrication, fast installation and low maintenance reduce whole-life operational costs, bringing superior long-term economic benefits.
8. Space-Saving Compact Structure
Flangeless integrated design avoids protruding structures, enabling compact installation and saving valuable building interior space.
Summary
UNTDuct PIR/PU aluminum pre-insulated duct system integrates high thermal efficiency, airtight performance, environmental safety and structural durability. It serves as a high-performance, cost-effective solution for modern HVAC construction and renovation projects.
