A duct board is a common form of heating and air conditioning insulation made out of fiberglass and a thin layer of foil. At CE, we have a vast inventory of fiberglass duct board , as well as the duct board silicone and sealants you need to install it correctly. It is produced using our dedicated manufacturing process that in increased product consistency for efficient fabrication.
The insulating qualities of compressed fiberglass reduces the temperature loss from air moving through the plenum and stops condensation from forming on the exterior surface of the duct plenum. Hi all, I have a question about duct board. I have been in the hvac field for three years as a service tech. These contain fiberglass internally. Several different techs have told me that this fiberglass comes loose when the system is on.

The metal duct work would have insulation in it also. If your not getting the you desire then change. The duct board reduces ventilation system noise and reduces condensation for improved performance.
R-value provides thermal efficiency. Boards aregroovedat fold lines with either shiplap or V-groove tools. Both methods remove the same amount of fiber glass.
The cuts and notches used to form a ductboard fiberglass duct need to be exact, or air moving through the duct will cause the loose fiberglass to break down and fall from the sides of the duct. Duct Board Plenum Kit - R6. As fiberglass falls from the duct , its insulating quality is reduce leading to increased inefficiency in the fiberglass duct. If I am going to have a supply plenum run for approx. Fiberboard duct board , made of fiberglass is one of the main types of duct board used in heating, ventilation and air conditioning applications.
Fiberboard is cut into 4-by-foot lengths of fiberglass, which are called sheets. The sheets are then routed to the proper size. Does not matter whether it is, or is not, combustible as the Type B Gas Vent is not allowed to touch insulation either, which is what duct board is. Requires the same air space to insulation as to combustible material. This is becoming less popular as more people become aware of the dangers and difficulties of using this fiberglass in their homes.
Fiberglass duct refers to two distinct types of ductwork. One type of fiberglass duct consists of a compressed fiberglass sheet with a metal foil backing, and the second type consists of fiberglass cloth bound with resin to form a strong solid material. Typical tools used to fabricate fiber board duct systems in the field include a yardstick or tape measure, straight edge, duct board knife, marking pen, and edge-cutting tools. A fiberglass board usually covered with aluminum foil on the outside.
Several boards can be assembled together to help airflow and maintain temperature. The fiberglass in a duct board serves primarily as an insulation barrier for the air passing through the duct. Board duct insulation is ideal for use in systems that operate below ambient temperatures and where a vapor barrier is required.
Standard duct board comes in sheets that are typically inches (1cm) wide by inches (2cm) long. On one side of the sheet is a thick layer of fiberglass insulation. On the other is a thin foil backing which serves as the outside of the duct. Lightweight boards are easier to transport and handle than insulated sheet metal ducts. Virtually eliminates air leakage thus saving energy and removing the need for system overdesign.
The board consists of insulation materials made from resin-bonded inorganic glass fibers. Like most products out there, a range of price and quality exist. Find out exactly what line they intend to use. Good duct board is , well, good. Cheap duct board is a problem waiting to happen.
An important feature to look for is the lining. Neoprene is a good choice. Anti-microbial is a good investment, as well. Understanding the correct size of fiberglass pipe insulation you need to order can be confusing at times, especially when distinguishing between Iron Pipe Size (IPS) and Copper Tube Size (CTS). It does have a higher friction rate than metal.
As the previouse guy mentioned metal is much better and if properly wraped with FSK ( duct wrap) it is much better. CHAPTER DUCT SYSTEMS SECTION 6GENERAL 601.
