SHEET METAL AIR DUCT AND FLEXIBLE AIR DUCT- WHAT IS THE DIFFERENCE?
September 12, 2017
By: Patricia Cermignano
According to Bryant®, ductwork is defined as "hollow pipes used to transfer air from the air handler to the air vents throughout your home". As ductwork is one of the most vital elements of any home cooling or heating system, it is important to understand the difference between Sheet Metal Air Ducts and Flexible Air Ducts.
Sheet Metal Air Duct
Sheet Metal Air Ducts are rigid air ducts primarily made of galvanized steel. They come in round, rectangular and spiral oval shapes. As sheet metal air ducts are firm, they require more prep-work as they are custom-fit and designed to the specific dimensions of the space they are being installed in. They are more durable than flexible air ducts as well. The sheet metal air ducts are connected directly to the cooling and heating system through the trunk line, which carriers the main source of air to/from the HVAC unit.
Flexible Air Duct
Flexible Air Ducts are made from pliable tubes of plastic which are often wrapped in insulated wire frames. Due to their flexibility, flexible air ducts can be installed in places that typically are more difficult to install sheet metal air ducts in. They are also used in conjunction with sheet metal air ducts to run air to individual registers in the ceilings. A few benefits of flexible air ducts are that they are relatively inexpensive, are generally easy to install and are lightweight.
