Non Insulated Flexible Duct

Non Insulated Flexible Duct – Product Description

The Non Insulated Flexible Duct is a versatile and economical air ducting solution commonly used in HVAC systems for air distribution. Made from high-quality aluminum foil or PVC laminated materials with a reinforced spiral wire helix, it offers flexibility and ease of installation, especially in areas where rigid ducts are difficult to fit. This duct type is suitable for both supply and return air systems where thermal insulation is not required.

Thanks to its non-insulated design, it is lightweight, compact, and easy to transport and store. It is most effective in indoor environments where the air temperature is controlled, and insulation is not a major concern.

Applications

• HVAC air supply and return systems in residential, commercial, and light industrial buildings

• Kitchen and bathroom exhaust systems
