PIR Foam Pre-insulated Duct board
Featuring high-performance PIR foam as the core substrate, PIR Foam Pre-insulated Duct board are lightweight composite materials that combine thermal insulation, structural strength and certified fire resistance as a complete assembly, widely applied in HVAC construction.
This integrated modular duct solution reduces system energy loss, expedites on-site installation, and sustains stable ventilation efficiency during long-term operation.

Are there any limitations or precautions for using PIR Foam Pre-insulated Duct board?
1. Not suitable for long-term high-temperature environment above 120℃
2. Poor resistance to strong acid, alkali and organic solvent erosion
3. Lower impact resistance compared with metal ducts, easy to crack under heavy collision
4. Not applicable for high-pressure wind pipe systems with extreme air pressure
1. Avoid direct exposure to open flame and high heat sources during installation and use
2. Keep away from corrosive chemical gas and liquid contact
3. Store panels in dry, cool place, prevent long-term sun exposure and rain soaking
4. Cut and construct with professional tools, avoid violent bending and extrusion
5. Strictly follow standard installation process to ensure joint sealing effect
6. Do not use in special flammable and explosive industrial ventilation occasions
What is the expected lifespan of PIR Foam Pre-insulated Duct board?
PIR Foam Pre-insulated Duct board: 20+ years of service life under standard indoor conditions.
Standard lifespan: 20+ years (indoor, commercial/normal industrial, proper installation & maintenance).
Conservative range: 15–20 years (humid coastal areas, moderate industrial exposure).
Closed-cell PU foam core: resists moisture, mold, and degradation.
Double-sided aluminum foil: corrosion-resistant, non-combustible, and aging-resistant.
Fully sealed joints: minimal air leakage, stable thermal performance over time.
GI ducts (with insulation): 5–10 years (prone to rust, insulation failure).
Flexible ducts: 10–15 years.
PIR Foam Pre-insulated Duct board:20+ years
Maintenance tip Annual visual inspection and cleaning of the outer surface keep it performing well for 20+ years
