Ductwork is an important system in homes. Hidden behind walls, its joints supply air to different rooms and can even assist with filtering it.

You might be surprised to learn that ductwork is very intricate and can be made with many different materials. This post will explore some types and how they’re secured together.

Types of Ductwork

  • Fiberglass: Fiberglass ductwork mixes sheet metal with fiberglass layers. This insulates the pieces to protect them from moisture and prevents the ductwork from making loud noises when running. This also makes them energy efficient. While useful, they can be difficult to clean. Because of this, spores can cling to the panels. It’s important to have them professionally cleaned at least once a year to prevent debris from getting blown into your home.
  • Fiberboard: This affordable option is composed of fiberglass sections that have been compressed. This compaction creates a solid barrier that stops allergens and air from escaping. Thanks to their thickness, fiberboard ductwork works well as an insulator so extra materials aren’t usually required. However, they can create friction which can hinder airflow.
  • Sheet Metal: Sheet metal is one of the most frequently available. Most selections are designed out of aluminum or galvanized steel. Aluminum tends to transport hot and cold air better. It’s also more durable. On the other hand, galvanized steel is more affordable and is a bit easier to maintain. Unlike fiberglass or fiberboard ductwork, sheet metal is more rigid. This way, it keeps its natural shape which can send air faster into a space. Because of its availability, sheet metal ductwork is commonly used in homes.

How Are These Pieces Put Together?

Ductwork winds through your home in different angles to exterior vents. How they’re connected depends solely on the type you choose and the design of your home. For instance, if the ductwork needs to be curved, flexible joints might be installed. Sometimes, expansion collars might also be used to fasten the joints. These wrap around the edges and keep the ductwork sections in place when they naturally expand and shrink. It also prevents them from making loud noises as they do so.

The type of ductwork your home uses might seem irrelevant but it can have a huge impact on your home’s air quality. If you’re concerned about your ductwork, give Dale HCS in Santa Rosa, CA a call. We’ll send our professionals out to quickly inspect and repair the system.
