Types of Ductwork: Everything You Need to Know
While it may be the least visible and least thought about feature of your HVAC system, ductwork, and its type, are of vital importance. Ductwork is the part of your system that moves air from place to place. If you do not have the proper ductwork installed, you run the risk of losing efficiency and increasing costs.There are many different options available, so it is helpful to have a general understanding of types. This list can help you get started when you are trying to determine the best ductwork to use for your home.
Best Types of Ductwork to Use
This type of duct work is created using fiberglass strands. These strands are compressed and then bonded by resin. Then, the duct is covered in foil to protect the fiberglass from moisture. While this type is advantageous due to its thorough insulation, the rough surface can restrict airflow efficiency and can harbor mold when used for ventilation.
There are times where traditional, rigid sheet metal duct board is not a possibility due to odd angles or space. This duct work is a flexible plastic tube, which is wrapped in a wire frame and then insulated with plastic. The flexibility means that there are fewer joints necessary, helping one to avoid elbows and other offsets.This type can be used for long sections without causing leaks. However, it does have the potential to leak at the seam created when it joins up to rigid ductwork like sheet metal duct.
This type of ductwork is probably the most recognizable form, and are made of either a galvanized steel or aluminum. Known as sheet metal ducts, they are lightweight and relatively easy to install. Due to the nonporous materials, they are one of the least likely to form mold.However, in tight spaces, it is difficult to efficiently install, as each seam caused by a turn or corner has the potential to leak air. The advantage of this type is that the material is very durable and unlikely to be punctured.
Fiberglass Duct Board
When it is beneficial or desired to lessen the sounds created by an air conditioner or furnace, fiberglass duct is used. They are the same in shape and design as a rectangular sheet metal duct but is coated with both internal and external fiberglass lining.While this ductboard does immensely lessen the noises, making it ideal for a commercial building with offices, there is a danger due to the fiberglass. The lining makes the duct difficult to clean, and damage to the lining can increase fiberglass floating in the air. Additionally, the rough surface makes it easier for bacterias and molds to take over.
