Flexible Ductwork Vs. Rigid Ductwork
When it comes to our homes, we always try to put in as much effort as possible.
In all aspects, from the conception, construction, and the designing of our homes, it’s completely normal to overthink every possible detail. The same can also be said about HVAC, (Heating, Ventilation, and Air Conditioning).
A lot of people overlook this process. If you’re one of those people, surely you also do not know a lot about the design, materials, and the details of an HVAC system.
In order to properly install a brand new HVAC system, you need to have extensive knowledge
One very important aspect of duct design to consider is the differences between flexible
This article will talk about the two types of ductwork; the rigid ductwork, and the flex ductwork, the pros and cons of each other, and any other information to help you in deciding what kind of ductwork is appropriate for your home.
What Is Ductwork?
Ducts are the conduit or the passageways that you use in an HVAC (Heating, Ventilation, Air Conditioning) System. Their main purpose is to deliver and remove air.
In HVAC, you use ducts to evenly distribute air at different temperatures from your cooling or heating system. This process involves taking in air from the house, cooling or heating it, and then returning it into your home.
Whenever you are undertaking a remodeling or a construction project, this is a major detail that you should not overlook. Some people make the common mistake of not thinking much about ductwork installation and regretting it at the end.
Without properly designed ducts, the overall equilibrium of your heating and cooling systems will be off and your home’s efficiency and climate control will suffer in the end.
Rigid and Flex Ductwork
We have talked about ducts being a channel from your HVAC system throughout your home. Now, there are two major types of ducts that you can choose depending on what you want and need.
These are rigid ductwork and flex ductwork. Both of these ductworks have specific features, pros, cons, and specifications.
Flexible HVAC Ductwork
This type of ductwork is usually
Using this kind of ducting is best in tricky spaces where rigid ducts are not just possible to install. They are also used to install ductworks which are not flexible to a certain air supply outlet.
Flexible ductwork uses cheaper materials and therefore is a cheaper option.
Rigid HVAC Ductwork
Rigid ductworks are known to be enduring and reliable. They are generally a more expensive option, but you get a higher quality duct that doesn’t make as much noise when
Here are some of the types of rigid ductwork:
- Fiber Board Ducts. Made from compressed fiberglass strands which are bonded with resin, and covered with a foil laminate for moisture protection.
- Fiber Glass Lined Ducts. Made from sheet metal ducts with internal and external fiberglass lining.
- Sheet Metal Ducts. The most common materials used for sheet metal ducts are aluminum and galvanized steel. These are the kinds of ducts you have seen in movies that a person crawls through.
Pros and Cons
Like most parts of an HVAC system, ductworks have also specific installation requirements. There are many differences between flexible
- It’s important to install flexible ductwork properly and with as little snaking or sagging as possible. The ductwork itself needs to be totally secure and supported.
Turns,bends, and kinks, needs to be minimized as much as possible as this can affect the air flowand efficiency of the HVAC system
- Flexible ducts are fairly easy to install and will often cost less than the rigid ductwork.
- Sheet metal ducts are less likely to incur dangerous mold and growths because their surfaces are
non porousand smooth.
- The fiberglass in some ducts can deteriorate with time, and will eventually release fiberglass
particles intothe air which might affect the health of the residents.
- Fiberglass lined ducts are also difficult to clean.
- Unlike sheet metal ducts, fiberglass ducts have a huge possibility for contamination with mold, mildew, and bacteria.
When installing ductworks, it is best that you contact a contractor and talk to them before anything else.
