PIR Pre-insulated Aluminum Duct Panel

PIR Foam Pre-insulated Aluminum Duct

PIR Pre-insulated Aluminum Duct Panel is a revolutionary "all-in-one" air distribution system designed to replace traditional "metal duct + lagging" setups. It features a rigid, high-density Polyisocyanurate (PIR) foam core sandwiched between two layers of embossed aluminum foil. This integrated structure delivers superior thermal efficiency, structural integrity, and installation speed, making it the ideal choice for modern commercial, industrial, and cleanroom HVAC applications.

Core Material: Rigid Polyisocyanurate (PIR) Foam

Core Density: 53 kg/m³ (High density ensures exceptional structural strength and rigidity)

Core Thickness: 20 mm (Standard; customizable up to 50 mm)

Thermal Conductivity: 0.022 W/m·K (Ensures minimal heat transfer)

Facings: Double-sided Aluminum Foil

Foil Thickness: 0.08 mm (80 microns)

Key Structural & Performance Advantages

1. Optimized Structural Strength (53 kg/m³ Density)

Unlike standard low-density insulation foams, this panel utilizes a 53 kg/m³ PIR core. This high density provides the panel with remarkable rigidity and load-bearing capacity. It maintains its shape under pressure, resists sagging over time, and allows for the construction of larger duct spans without the need for excessive bracing.

2. Superior Thermal Efficiency (λ=0.022 W/m·K)

With a thermal conductivity of just 0.022 W/m·K, the PIR core offers one of the highest R-values per inch in the industry. At 20mm thickness, it effectively prevents condensation and minimizes heat gain/loss, ensuring that conditioned air reaches its destination at the desired temperature. This results in significant energy savings for the HVAC system (up to 20-30% reduction in energy consumption).

3. Durable & Hygienic Aluminum Facings (0.08 mm)

The 0.08 mm aluminum foil facings provide a robust vapor barrier and structural skin for the foam core.

Hygiene: The smooth, non-porous aluminum surface prevents the growth of mold, mildew, and bacteria, making it suitable for hospitals, laboratories, and food processing plants.

Protection: The foil acts as a tough barrier against physical damage during installation and corrosion in humid environments.

4. Airtight & Fast Installation

The panel features precision-engineered tongue-and-groove joints. When assembled with sealant, the system achieves air leakage rates of ≤2% (compliant with EN 1507 and AS/NZS 3660.1 standards). The lightweight nature of the panel (approx. 2–3 kg/m²) allows for rapid installation, reducing labor costs by 40–60% compared to traditional metal ductwork.

5. Fire Safety Compliance

The PIR core is formulated to be fire-retardant. It meets international fire safety standards, including Class 0 (Surface Spread of Flame) and Class 1 (Smoke Emission) per BS 476 Part 6 & 7, as well as AS 1530.3 for Australian markets. In the event of a fire, the high-density core chars to form a protective barrier, inhibiting flame spread.
