About Insulated Duct

Insulated Duct

Insulated Duct is constructed with a spring steel wire helix encapsulated in a 2 ply, air tight black inner core. Thermal efficiency is provided by fiberglass insulation encompasses the core. The outer jacket is made of tough metalized polyester film laminate, which acts as vapour barrier surface as well.

Superior Insulation and Thermal Efficiency

Our insulated duct systems use either polyethylene foam or glass wool, efficiently minimizing thermal loss and energy costs in HVAC and ventilation systems. The polished aluminum foil exterior provides additional protection and fire retardancy, ensuring your ducts remain safe and effective over a long lifespan. Multiple thickness options allow customization for your specific thermal requirements.

Ideal for Demanding Industrial and Commercial Environments

Designed for high-performance air handling, these ducts are suitable for applications involving HVAC, air conditioning, and ventilation in factories, office complexes, malls, and large commercial spaces. The combination of a galvanized steel inner duct and industrial-grade insulation withstands high air velocities and temperature variations, making them a smart choice for heavy-duty installations.

Customizable Shapes, Sizes, and Accessories

With flexible configuration options-round or rectangular shapes, customizable diameters, and lengths up to 10 meters-these ducts adapt seamlessly to diverse architectural needs. Accessories like connectors and insulation clamps, along with options for polished or matte finishes, ensure a tailored ducting solution that meets both technical and aesthetic standards.

FAQ's of Insulated Duct:

Q: How are the insulated ducts installed in HVAC systems?

A: The insulated ducts are mounted using standard duct mounting techniques with supplied accessories such as connectors and insulation clamps. Their flexible length (up to 10 meters) and customizable diameters make them suitable for integration into both new and existing HVAC, air conditioning, or ventilation systems.

Q: What benefits does the polyethylene or glass wool insulation provide?

A: Both polyethylene foam and glass wool insulation offer excellent thermal and acoustic performance, reducing energy loss as well as minimizing noise. The choice of insulation material can be customized to give you the best balance between cost, fire resistance, and sound attenuation for your application.

Q: When should I choose a specific insulation thickness for my ductwork?

A: The required insulation thickness-13mm, 25mm, or 50mm-depends on your application's thermal, sound, and energy requirements. Thicker insulation is ideal for environments needing greater temperature control and noise reduction or where higher energy efficiency is desired.

Q: Where can these insulated ducts be used?

A: These insulated ducts are versatile and designed for use in industrial facilities, commercial buildings, warehouses, shopping centers, and anywhere reliable air movement and thermal control are necessary.

Q: What is the process for customizing duct shape and size?

A: Simply specify your preferred shape (round or rectangular), diameter, and desired insulation thickness or length (up to 10 meters). The manufacturer will process your order according to your requirements, ensuring a precise fit and optimal efficiency.

Q: Can these ducts handle high air velocities and temperature variations?

A: Yes, these industrial-grade ducts are rated to tolerate air velocities up to 40 m/s and temperature ranges from -20C to +80C, making them ideal for dynamic and demanding air handling environments.
