Pre-insulated Aluminum Duct Panel

Polyisocyanurate(PIR) Foam Pre-Insulated HVAC Ductwork Panel is a high-performance, all-in-one solution designed for modern heating, ventilation, and air conditioning (HVAC) systems. Built with a precision-engineered sandwich structure, it features a dense Polyisocyanurate(PIR)foam core-celebrated for its exceptional thermal insulation properties-sandwiched between two protective layers of corrosion-resistant aluminum foil. This factory-prefabricated panel merges insulation, structural strength, and airtightness into a single component, eliminating the need for separate insulation installation and streamlining ductwork setup in diverse buildings.

Structural and material characteristics of Pre-insulated Aluminum Duct Panel

The product adopts a "aluminum surface layer + insulation core material + aluminum surface layer" sandwich composite structure. The surface layer uses 150–200μm aluminum sheet/ 60 micron embossed aluminum foil, which is corrosion-resistant, impact-resistant, has a smooth surface and low wind resistance.

The core material is high-density closed-cell PU/PIR, with low thermal conductivity and stable structure. The integrated composite process eliminates layering and hollowing, balancing the strength of the metal duct and the heat insulation performance of the insulation material.

The overall weight is only 20%–25% of that of traditional iron sheet ducts, significantly reducing the building load.

Core performance advantages of Pre-insulated Aluminum Duct Panel

Energy saving and insulation: The closed-cell structure blocks the transfer of heat, and the aluminum surface layer reflects infrared heat, reducing system energy consumption by 15%–20%, resulting in significant long-term operational benefits.

Fire safety: The core material reaches B1 level flame retardancy, with no dripping during combustion, less smoke, and no toxicity. It complies with domestic and international fire safety standards such as ASTM E84 and GB 8624.

Air tightness and moisture prevention: The overall sealing is excellent, with no air leakage or condensation, effectively inhibiting mold growth, suitable for scenarios with high hygiene requirements such as clean rooms and hospitals.

Durability and corrosion resistance: The aluminum surface layer is resistant to acid and alkali and anti-aging, with an outdoor service life of 15–20 years, far exceeding that of traditional ducts.

Construction and Operation Value of Pre-insulated Aluminum Duct Panel

Factory prefabrication, on-site cutting and assembly, eliminating the on-site insulation process, results in a project duration reduction of over 50%, with significant decreases in labor and material costs.

The panels can be flexibly processed into various shapes such as elbows, reducers, and trisets, suitable for complex layouts. The surface is easy to clean and has a low maintenance frequency, resulting in low long-term operation costs.

The lightweight feature reduces the difficulty of hoisting and enhances construction safety, making it suitable for renovation and new construction projects.
