When it comes to air conditioning systems, there are three main types of ducts: flexible, rigid, and semi-rigid. Each type has its own advantages and disadvantages, so it's important to understand the differences between them before starting a large air conditioning project. In this article, we'll provide a comprehensive guide to the different types of ducts and their uses.Flexible DuctsFlexible ducts are composed of a coil of metal wire covered with a layer of flexible plastic. They usually appear as a cube and have no elbows or gaps.
Thermal insulation is made of glass wool, polyethylene, or metallized PET. Flexible ducts are preferred in homes where space is limited.
Rigid Ducts
Rigid-type ducts are similar to sheet metal ducts but have an internal or external fiberglass coating. This type of duct is preferred in commercial buildings and offices since it has the ability to dampen the sound of air conditioning. Rigid-type ducts can also be lined with fiberglass.Semi-Rigid Ducts
Semi-rigid ducts are made with a steel spring coil wrapped in a propeller and covered with flexible plastic.They are less expensive than rigid ones but more versatile and easier to install. The 2-layer polymer plastic is extremely versatile and can be folded around obstructions, making them suitable for tight and uncomfortable spaces.
Sheet Metal Ducts
Sheet metal is the most common type of the four duct materials. It is made of galvanized steel or aluminum and is very durable, protecting ducts from dirt and dust. The inside of sheet metal ducts usually attract dust and other particles, but it's usually easy to clean the smooth inner surface.Fiberboard Ducts
Fiberboard is made of fiberglass yarns that have been bonded together with resin.The surface is textured with aluminum foil on top of the outside to insulate it. Fiberboard is good for maintaining temperature for longer, such as during a heating service, because of its insulation value.
Oval Ducts
Oval ducts belong to this class and are perfect for narrow-walled cavities, although technically they are only flattened round ducts.When selecting the right type of duct for your air conditioning system, it's important to consider all the factors involved. Sheet metal is the most common type due to its durability and easy maintenance. Flexible ducts are cheaper compared to the other three options and are easier to install than rigid ducts.Fiberboard is good for maintaining temperature for longer but can be difficult to clean due to its outer texture.Before beginning a large air conditioning project, make sure you know all the aspects involved, including the different types of ducts available. This comprehensive guide should help you make an informed decision when choosing the right type of duct for your home or commercial building.
