Flexible Duct Vs Metal Duct

Flexible ductwork is going to be cheaper than metal ducts in nearly every case.

Flexible duct vs metal duct.

What s the best choice for you. Flex must be oversized at least one duct size. Rigid ductwork sheet metal ducts are less likely to incur dangerous mold and growths because their surfaces are non porous and smooth. Installation of rigid metal ducting must be completed by an experienced skilled professional and is often more complicated to be installed than flexible ducting.

In comparison to metal duct flex duct is easier and faster to install. Air flow in a flex duct tends to tumble probably because of the rib like intrusion every inch or so. Air flow in a steel duct tends to travel smoothly in a coil like motion. This is because they re more versatile and flexible.

Flex ducts are better for existing trunk and branch heating and cooling systems. Metal ducts are more rigid due to the nature of steel making them ideal to build an entire hvac system. When you use flexible ductwork instead of metal ducts you will save some substantial money. Flex duct has an inherent flaw based on the very attributes that make it flexible.

The inner liner ribs restrict airflow more than sheet metal ductwork but not significantly. Flexible ducts are fairly easy to install and will often cost less than the rigid ductwork. Flexible ducts are good for air quality because you are not breathing in fiberglass insulation lined ductwork like the fiber air ducts and they are mold and rust resistant unlike galvanized sheet metal ductwork.
