Insulated Ducts That Save Time
Traditional ducts need insulation added on-site. Our XPS Metal Composite Air Ducts come with insulation built in. The outer layer is embossed metal sheet, aluminized zinc steel, or stainless steel. The middle is XPS extruded foam board. The inner layer is galvanized steel, aluminized zinc steel, or stainless steel. This sandwich structure eliminates the need for extra insulation wrapping. It reduces installation steps. The embossed surface looks good and adds strength. Yancheng Lima Air Conditioning Engineering Co., Ltd. has been making efficient air distribution systems since 1996.

Lightweight and Easy to Assemble
Weight affects installation cost. Our XPS Metal Composite Air Ducts are lighter than traditional metal ducts with external insulation. The corners use ABS injection-molded parts and aluminum profiles to form a frame. The assembly is quick. The flanges connect with C-type aluminum sections. This system is faster than old angle iron flange methods. The seals are tight. Air leakage is much lower than with ordinary ducts. This saves energy and improves system performance.
Perfect for Projects with Space and Time Constraints
These ducts are a good fit for many applications. They work well for central AC supply and return air, fresh air systems, and cleanrooms. They are ideal for commercial buildings and industrial plants that need good insulation, fire performance, and low noise. Because they come pre-insulated, you skip the on-site insulation step. This shortens the construction schedule. The metal surfaces resist corrosion and deformation. They are built for long-term use. Our factory prefabricates with precision to ensure quality.
Frequently Asked Questions (FAQ)
Q: Do I need to add insulation after installing these ducts?
A: No. The XPS foam core provides the insulation. No additional wrapping is needed.
Q: How is the duct connected?
A: The duct uses ABS corners and aluminum profiles to form a frame. C-type aluminum sections connect the flanges.
Q: Are these ducts suitable for cleanrooms?
A: Yes. The smooth inner surface and tight seals make them a good choice for cleanroom applications.
