Pre-insulated PID Aluminum Sheet

Pre-insulated PID Aluminum Sheet is a composite panel with aluminum foil facing and closed-cell PID insulation core, formed by continuous lamination. It delivers ultra-low thermal conductivity, excellent airtightness, moisture resistance and corrosion protection. Lightweight yet structurally rigid, it simplifies on-site fabrication and installation for HVAC ducts, cold chain and industrial insulation. Fire-retardant, eco-friendly and long-lasting, it cuts energy loss significantly, ideal for commercial buildings, factories and logistics facilities seeking high-efficiency thermal solutions.

Product Structure and Core Performance of Pre-insulated PID Aluminum Sheet

Air Tightness and Moisture Resistance
The overall closed-cell structure of the panels prevents water vapor from penetrating. After the seams are sealed, the system has excellent air tightness, significantly reducing the risk of condensation and moisture accumulation, preventing the insulation layer from getting damp and failing, and extending the lifespan of the system.

Fire Safety Grade
The PID core material is a non-flammable B1 grade material. It does not drip when exposed to fire and does not produce toxic smoke. It complies with building fire safety standards and is suitable for densely populated places such as shopping malls, hospitals, and office buildings.

Mechanics and Dimensional Stability
The aluminum surface enhances bending and compression resistance, the sheet has high flatness, and the thermal expansion and contraction coefficient is small. After installation, it is less likely to deform or warp, ensuring the long-term stable operation of the ventilation duct system.

Construction and Application of Pre-insulated PID Aluminum Sheet

Lightweight for Cost Reduction and Efficiency Enhancement
The density is only 40–50 kg/m³, approximately 1/5 of that of traditional iron sheet ducts, significantly reducing the roof and structural loads, lowering transportation and hoisting costs, and offering significant advantages for high-rise and large-span projects.
Integrated Construction Simplifies Processes
Combining the air duct with insulation, it is formed on-site in one step, eliminating the need for secondary insulation and aluminum sheet wrapping processes, reducing the construction period by 40%–60% and significantly lowering labor and material costs.
Customization for Multiple Scenarios
It can be customized in terms of thickness, width, and aluminum foil specifications, with convenient cutting, bending, and bonding, suitable for rectangular air ducts, special-shaped pipe fittings, and equipment insulation, as well as scenarios such as HVAC, clean rooms, and cold chain storage.
