Phenolic Duct Foam Aluminum Boards

Phenolic Pre-insulated Duct Panel with 60/80 micron Aluminum Foil

---

UNT Phenolic Pre-insulated Duct Panel with 60/80-micron aluminum foil is a high-performance building material, combining phenolic foam's excellent thermal and acoustic insulation with the protective properties of aluminum foil. 

The 60/80-micron aluminum foil layer enhances moisture resistance, durability, and fire safety, while the phenolic core ensures low thermal conductivity (≤0.023 W/m·K) and lightweight installation. 
Ideal for HVAC systems, it offers energy efficiency, corrosion resistance, and compliance with fire safety standards, suitable for commercial, industrial, and humid environments.

Why Choose UNT Phenolic Pre-insulated Duct Panel?​

---

1.Excellent Thermal Insulation Performance
Phenolic foam has a low thermal conductivity (typically ≤0.03 W/m·K), effectively reducing heat transfer and energy loss in HVAC systems.
2. Lightweight and Easy to Install
The panel is significantly lighter than traditional metal or concrete duct materials, reducing transportation costs and installation labor.
3. Fire Resistance and Safety
Phenolic foam is non-combustible and meets strict fire safety standards (e.g., Euroclass B-s1, d0 or UL 94 V-0), producing minimal smoke and toxic fumes when exposed to fire.
4. Moisture and Corrosion Resistance
The closed-cell structure of phenolic foam resists water absorption, preventing mold growth, rust, and degradation in humid environments.
5. Acoustic Insulation Properties
The foam structure dampens air-borne noise and reduces duct-borne vibrations, contributing to quieter indoor environments.
6.Durability and Long Service Life
Phenolic panels are resistant to chemical corrosion, aging, and mechanical damage, maintaining performance over decades without degradation.
