Duct board vs sheet metal plenum.

Duct board vs metal plenums supply is on perferable over the other. Sharp edges inside will cause material erosion. Proper aspect ratio for velocity and pressure drop is more important than sheet metal. Duct board is ok if the system design is correct and the duct and fittings are properly made and installed.

26 ga duct plenum. The faced coated duct board behaves only slightly rougher than sheet metal but does not have joint inter ruptions so we estimated it as overall slightly 5 rougher. Duct board r 6 features fiberglass construction with an fsk backing for sturdiness over time. Regardless of construction material the heart of an.

25 feet should it be ductboard or metal and is hard pipe runs preferable over flex. Cut this duct board to size and use it to build your own hvac fittings or trunk duct and then assemble it with fiberglass weave and mastic or duct board approved duct tape for a convenient solution to your ducting problems. High air velocity will destroy the fiberglass material. It is not rodent proof.

Some sheet metal air ducts are lined with an external or internal fiberglass duct liner. There s no filter to catch these fibers on the supply side of your hvac system. The master flow 48 in. Fiberglass lining is used to insulate air ducts from heat loss or to avoid condensation in cases where the supply air is very cold or there is a high ambient humidity in the plenum.

Typically hvac duct systems are made of sheet metal but other rigid heatproof materials such as fiberglass or insulated plastic may be used. The uncoated duct board classified as a medium roughness is controlled by higher surface friction. Sheet metal products 8 x 20 x 20 in. Consequently these glass strands can be carried with the airflow into your living space.
