HVAC Air Duct PIR/PU Foam Panel

PIR/PU Foam HVAC Air Duct Panels are two high-performance pre-insulated solutions for heating, ventilation, and air conditioning systems. Both adopt a sandwich structure with foam cores and protective facings, but differ in material properties-catering to diverse project priorities like fire safety, energy efficiency, or cost. They're mainstream choices for modern commercial and residential HVAC ductwork.

Core Structure & Shared Specifications

Common Structure: Both feature a closed-cell foam core (10–40mm thickness) bonded to aluminum foil or thin metal facings (0.05–0.08mm) on both sides. The facings ensure airtightness, corrosion resistance, and structural rigidity.

Shared Metrics: Foam density of 45–55 kg/m³, water absorption ≤0.1%, working temperature range of -60℃ to +80℃ (continuous operation ≤70℃), and airtightness leakage <2%. Both meet international HVAC standards for durability and safety.

Internal Use:

Panel Structure: Silver Alu. / PIR Foam / Silver Alu.

Foam Density: 50kg/m3

Panel Dimension: 3950/2950/2900*1200mm*20mm

Alu. Foil: Embossed 60 or 80 Micron

Core Advantages (Combined)

Efficient Energy Savings: Both minimize heat loss/gain-PU excels with lower thermal conductivity (cuts energy use by 20–30%), while PIR delivers reliable efficiency for standard needs.

Easy Installation: 70% lighter than galvanized steel ducts, pre-fabricated for one-step assembly (no secondary insulation). They're easy to cut and fit tight spaces, slashing labor time by 40–60%.

Moisture & Hygiene: Closed-cell cores block moisture entirely, and smooth foil facings resist dust, mold, and bacteria-suitable for hospitals, food plants, or humid coastal areas.

Durable & Low-Maintenance: Both have a 20+ year lifespan, with facings resisting rust and corrosion. Minimal upkeep (occasional cleaning) ensures long-term performance.
