Your ductwork plays the critical role of directing heated or cooled air from your HVAC system to different parts of your home. It's also the channel through which air is returned to your furnace or air handler to be treated. You can choose between different ductwork materials, with each having its own perks and quirks. Let's explore the different types of ductwork material to help you identify the best one for your heating and cooling needs.
Sheet Metal
This type of ductwork is made of aluminum or galvanized steel. It's very durable, and its nonporous surface makes it the least likely to develop biological growth. The smooth interior surface usually traps particles like dust. If you choose sheet metal for your home, it's advisable to have the ducts cleaned by a professional occasionally to maintain good indoor air quality.
Fiberglass
Some sheet metal ducts have an internal or external fiberglass lining to insulate against heat loss. The lining lowers the HVAC system's sound, making it a popular option for offices and commercial buildings. With a sealed interior lining, the fiberglass ducts will need intense cleaning, which can reduce durability. Fiberglass ductwork can also be contaminated with mold and bacteria.
Fiberboard
Fiberboard ductwork is usually the most inexpensive ductwork system to install. It's constructed with resin-bonded fiberglass strands. The exterior has foil that serves as a water retarder and air barrier. The strands make the interior textured. Consequently, the crevices can trap dust and debris, posing an indoor air-quality concern. The rough surface can affect airflow and efficiency.
Flexible Ducts
Flexible ducts comprise a steel spring coil encapsulated in thick plastic. They're lightweight, inexpensive, and easy to install. Their flexibility makes them ideal for installation in tight spaces that can't accommodate rigid ductwork. Flexible ducts have inner ribs that cause more airflow restriction than sheet metal ducts.
Kinks, turns, and bends should be minimized during flexible duct installation, as they can hurt HVAC performance. Therefore, it's essential to work with a quality HVAC installer. Flexible ductwork is good for indoor air quality.
The best ductwork material for your home will depend on its overall design and your specific circumstances, such as the need for noise reduction or heat retention, as well as your budget.
