I just don t know what that is.

Duct board vs sheet metal.

I don t know what kind of cardboard and i m sure there s a name for it. If you re going this far perform a flowhood test to determine where how much improved airflow can be had. Coat seal the interior of the duct board using an airless sprayer. Metal ductwork needs design measurement and installation by or with the help of an hvac professional.

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. Duct board is ok if the system design is correct and the duct and fittings are properly made and installed. Replace redesign the duct board with sheet metal. The inner liner ribs restrict airflow more than sheet metal ductwork but not significantly.

Odds are the efficiency airflow of your duct system can be greatly improved. I have never liked duct board or ducts lined with fiberglass. 25 feet should it be ductboard or metal and is hard pipe runs preferable over flex. The porous surface seems like it would affect air flow i understand properly sized this shouldn t be a problem collect more dirt than metal delaminate and come apart over time and are very hard to clean once dirty.

Duct board vs metal plenums supply is on perferable over the other. If i am going to have a supply plenum run for approx. You need a pro for this. It hasn t been on the market long enough to weigh in on its merits and shortcomings and will not be included in this comparison.

When homeowners receive quotes from hvac contractors they typically are given two duct replacement options sheet metal or fiberglass duct board. Proper aspect ratio for velocity and pressure drop is more important than sheet metal. Sharp edges inside will cause material erosion. The idea of the porous insulation on the interior just doesn t seem like a good idea.

High air velocity will destroy the fiberglass material. There is a third option phenolic duct that is made of plastic foam with a foil liner on the inside and exterior. There actually are a few reasons most hvac techs prefer metal ducting. Poor fastened and sealed connections.

Up from the furnace comes a metal ducting duct work that goes up. While flex ducts work best for short runs in a trunk and branch system metal duct works best for entire air distribution systems. It is not rodent proof.
