When choosing what type of duct you should use for your building, spiral ducts are the best choice. Spiral ducts, which can be oval or round shaped, have many advantages compared to square ducts. Below are the benefits of oval ducts and three reasons why you should choose them for your commercial duct use.
What Are Spiral Ducts?
Ducts are passages used to deliver and remove air in either residential or commercial buildings. Spiral ducts and flat oval ducts are made from sheet metal which is metal that is cut into thin and flat pieces that range from 30 to 8 gage. Spiral ducts may be used in commercial buildings for aesthetic purposes, but they have many benefits besides looking nice.
Oval Ducts Are Cheaper
Flat oval ducts are the cheaper alternative because they use less sheet metal when being produced than square ducts. Flat oval ducts are partially cheaper due to the shape and not having corners, but also because they are made up of round spiral ducts. Flat oval ducts are mostly only flat in the trunks, and the branch fittings are typically round resulting in not having to use elbows. This saves material while also making the ducts more efficient.
Flat Oval Ducts Are More Efficient
Not only are flat oval and round spiral duct systems cheaper to buy, but they are also cheaper to operate. Flat oval ducts have higher efficiency due to leaking less than square ducts because they do not have rigid seems. Flat oval ducts are easier to seal and result in fewer leaks. Flat oval ducts also have reduced noise due to not having corners to cause turbulence to the airflow which results in resistance and vibration.
Flat Oval Ducts Fit into Smaller Spaces
For your commercial building, flat oval ducts are recommended because of their size. Due to having a flat side, the oval ducts can be installed against the ceiling which minimizes the amount of space it takes up. This results in the ceiling not losing any height while still maintaining the amount of airflow.
When choosing which type of ducts you should use in your commercial space, remember all of the benefits that round spiral ducts and flat oval ducts offer over traditional rectangular ducts.
