Comparison of Pre-insulated Ducts and Traditional GI Ducts

Comparison of PIR/PUR/Phenolic Pre-insulated Ducts and Traditional Metal Ducts (GI Ducts)

PUR/PIR Foam Pre-insulated HVAC Ducts is new generation Air Duct, which is ideal for specifications where space or weight is restricted.

What are the advantages of Pre-insulated ducts?

Superior Insulation: 

PIR/PUR has a low thermal conductivity, offering excellent insulation and reducing energy loss.

Lightweight: 

Polyurethane insulation board are relatively lightweight, making them easier to transport and install, reducing the burden on construction.

Moisture and Corrosion Resistance:

PIR/PUR duct panels have good resistance to moisture and corrosion, making them suitable for humid or corrosive environments.

Low Noise:

Polyurethane insulation boards have good sound insulation properties, reducing noise during duct operation.

Easy Installation:

PIR/PUR air duct panel is lightweight and easy to cut and shape, speeding up the installation process.

Disadvantages of Traditional Metal Ducts

High Thermal Conductivity:

Compare with PIR & Polyurethane insulation board, metal materials have high thermal conductivity, offering poor insulation and requiring additional insulation layers.

Heavy Weight: 

Metal ducts are heavier than Pre-insulated ducts, which increases the difficulty of transportation and installation.

Prone to Corrosion: 

They are susceptible to rust and corrosion in humid environments, requiring regular maintenance and anti-corrosion treatments.

High Noise: 

Metal materials conduct sound, resulting in higher noise levels during operation.

Summary of Pre-insulated Ducts

PU/PIR/Phenolic Foam Pre-insulated HVAC Duct is an excellent alternative to traditional galvanized iron sheet metal ductwork. Polyurethane insulation board is ideal for specifications where space or weight is restricted. Compared with heavy galvanized sheet metal ducting that requires a second step to its installation process to both steam seal and thermally insulate ductwork, Pre-insulated air duct offers a high performance lightweight and robust ductwork system that requires only a single fix installation process. PU Duct and PIR Duct not only makes it a high-speed operation for projects on which time is critical but also provides the advantage of a considerable saving in cost and space. Pre-insulated air duct system can make a saving of over 20% on operating cost over 30year life.
