PIR Air Ducting Board

 

Materials and Structure

 

It usually adopts a sandwich structure, with closed-cell insulating materials such as polyurethane (PU) or polyisocyanurate (PIR) foam as the core, and both sides are covered with aluminum foil, aluminum plates, or pre-coated galvanized steel plates

Excellent Thermal Insulation: It features low thermal conductivity. For example, the thermal conductivity of PIR core air duct boards made of PIR (polyisocyanurate) can reach 0.020-0.022 W/(m·K), which effectively reduces heat transfer, improves the energy efficiency of HVAC systems, and lowers operating costs.

Lightweight: Compared with traditional metal air ducts, PIR core PID air duct boards are lighter. For instance, UntDuct's PID air duct board only weighs 1.4 kg per square meter, making it easy to handle and install. This not only reduces the load on the building structure but also cuts down installation costs.

High Air Tightness: The air duct board has excellent sealing performance. For example, the air tightness of UntDuct's PIR system is 8 times higher than that of traditional air ducts, which minimizes air leakage and enhances the operating efficiency of the system.

Good Fire Resistance: Some air duct boards comply with relevant fire safety standards. For example, UntDuct's PIR panels have passed the certification of the BS 476 fire standard. When exposed to fire, a carbonized layer forms on the foam surface, which prevents the spread of flames and avoids the release of harmful gases.

Antibacterial and Mildew-Proof: It has a smooth surface that is not prone to dust accumulation. Some air duct boards adopt antibacterial aluminum foil, which possesses antibacterial and mildew-proof properties. This ensures indoor air quality and makes the boards suitable for places with high hygiene requirements.

FAQs of PIR Foam Pre-insulated Aluminum Duct

Do PIR pre-insulated (PI) ducts require additional insulation after installation?

No. Unlike traditional steel ducts (which need separate insulation layers like fiberglass), PIR pre-insulated panels are factory-insulated with integrated facing. This eliminates the need for secondary insulation work, saving time and labor.

In which scenarios is PIR pre - insulated duct sheet suitable?

It is widely used in commercial buildings such as offices, shopping malls, and hotels, as well as in residential complexes, industrial facilities, healthcare and food processing facilities, and cold storage and refrigeration systems.

How is PIR pre - insulated duct sheet packaged?

-

It is usually packaged in plastic film or cartons, with 10 sheets per package.

How to maintain PIR pre-insulated (PI) ducts?

Maintenance is minimal. Regular inspections for joint tightness (to prevent air leakage) and surface damage (e.g., punctures in aluminum facing) are recommended. Cleaning the inner surface periodically (with mild detergents) helps maintain airflow efficiency, especially in hygiene-sensitive areas.
