Pre-Insulated duct material

Pre-insulated air duct material is an integrated high-performance composite panel designed specifically for HVAC duct systems. Featuring a sandwich structure with a rigid foam insulation core, it is laminated with aluminum foil or metal panels on both sides, integrating structural support, thermal insulation, airtightness, anti-seepage, and surface protection in one product.

Core Structure：

Outer layer: Embossed aluminum foil / Galvanized steel sheet(Provides protection and sealing, improving overall durability)

Core layer: Closed-cell rigid foam(Three material options: PU/Polyurethane, PIR/Polyisocyanurate, phenolic foam)

Forming process: One-step factory molding(Stable dimensions, high flatness, no secondary on-site insulation processing required)

Main Material Types & Performance Parameters

1. Polyurethane (PU) Pre-insulated Air Duct Panel

Thermal conductivity: λ ≈ 0.020 W/m·K (Lower thermal conductivity means better insulation performance)

Key advantages: Excellent thermal insulation, lightweight, easy to cut and install, high compressive strength, low water absorption, effectively prevents condensation

Applications: Conventional HVAC systems, office buildings, shopping malls, hotels and other general commercial buildings.

2. Polyisocyanurate (PIR) Pre-insulated Air Duct Panel

Thermal conductivity: λ ≈ 0.020 W/m·K, insulation performance comparable to PU

Key advantages: Superior fire resistance, self-extinguishing, low smoke emission, wide operating temperature range (-60°C to 90°C), meets ASTM E84 Class 1 fire rating

Applications: Projects with high requirements for fire protection and temperature resistance, such as hospitals, data centers, cold storages, precision electronics factories.

3. Phenolic Foam Pre-insulated Air Duct Panel

Thermal conductivity: λ ≈ 0.025 W/m·K, stable thermal insulation performance

Key advantages: Non-combustible, no flame spread, low smoke emission and low toxicity during combustion, extremely high safety and stability

Applications: High-safety venues, such as subways, tunnels, clean rooms, high-rise buildings, civil air defense projects.
