Pre-insulated PIR Duct System
If you're a contractor looking to streamline HVAC installations without compromising performance, the Pre-insulated PIR Duct System is a smart upgrade. These systems combine lightweight construction, high thermal efficiency, and fire safety-perfect for demanding commercial and residential projects.
The Pre-insulated PIR (Polyisocyanurate) Duct System utilizes PIR foam as the core insulation material, laminated with surface layers such as aluminum foil, or aluminum sheets. This structure achieves B1-grade fire resistance (GB 8624-2006), ensuring non-combustibility and zero emission of toxic smoke when burned. The system is CFC/HCFC-free, aligning with global environmental standards.
Key Advantages of Pre-insulated PIR Duct System for Contractors:
A. Lightweight & Rapid Installation
Weight Reduction:
85% lighter than traditional galvanized iron ducts.
Eliminates the need for heavy lifting equipment, reducing labor costs and safety risks.
Modular Design:
Prefabricated panels enable on-site assembly, cutting installation time by 40–60% versus traditional ducts requiring secondary insulation.
CNC cutting machines ensure precision, minimizing material waste.
B. Superior Fire Safety & Durability
Fire Resistance:
B1-rated PIR core forms a carbonized layer when exposed to flames, halting fire spread.
A-grade metal outer layers (e.g., aluminum, painted steel) provide additional protection.
Longevity:
20+ year lifespan due to corrosion resistance, moisture immunity, and zero condensation.
No maintenance required post-installation, reducing lifecycle costs.
C. Acoustic & Aerodynamic Efficiency
Noise Reduction:
3 dB/m average sound attenuation, eliminating the need for separate silencers.
Outlet noise ≤47 dB, meeting residential/commercial comfort standards.
Low Air Resistance:
Airflow-optimized design reduces friction, lowering fan energy consumption by 15–20%.
D. Cost-Effectiveness & ROI
Initial Cost:
10–15% higher than galvanized iron ducts.
Long-Term Savings:
50% reduction in energy bills due to superior insulation.
20% faster project delivery translates to earlier revenue generation.
