If you ask the average fellow on the street, he would likely not be able to tell you the differences between spiral ductwork and oval ductwork. We live alongside many devices and details in our everyday lives that never reveal the source or reason for their existence. Ductwork, whether they be spiral ducting or oval, is very important in our homes and offices and you might never even see it.
In many homes, somewhere between 20 to 30 percent of the air that makes its way through the duct system gets lost to leaks, holes, and through spaces created by ducts that are poorly connected. You might notice by way of your utility bills that your duct system isn’t working as efficiently as it once did, but it can be difficult for the untrained person to spot these types of problems.
Ducts that are fabricated properly can help reduce the costs of your energy bills by performing in a way that keeps the air flowing where it should be. Ducts are made with a couple of different types of materials. Sometimes, stainless steel ductwork might cost a little more, but commercially or industrially, it can very often be the preferred material over galvanized steel or aluminum. If there is danger of some kind of hazardous air being ventilated from research facilities or laboratories, your ductwork has to be up to the task.
In the United States, 90% of homes have ducted heating and cooling systems installed. Depending on where you live, you might need a different type of ductwork. A spiral duct that wouldn’t necessarily work well in one location might just be perfect in another.
Spiral duct installation will include the product, parts, labor, warehousing, transportation, packaging, and waste removal and can be quite a bit less expensive than rectangular duct.
Sometimes, in the right locations, you might need to wrap up and cover an exposed spiral duct. On occasions such as these, you might be better off going with an aluminum duct over a stainless steel. Othe situations where you might choose aluminum over stainless steel would be areas around indoor swimming pools, where you would need more flexibility.
