What is duct wrap used for?
Duct wrap insulation reduces heat loss or gain through duct walls, conserving energy and controlling moisture condensation. Fibrous glass duct wrap insulations are useful in situations where acoustical performance is not an issue.
What type of insulation is used for ductwork?
The most common material used for insulating heating and cooling ducts is fiberglass. Fiberglass duct insulation is available in various thicknesses and R-values and in either a flexible or rigid form. The flexible type comes in rolls and is relatively easy to install on either round or rectangular ducts.
What is duct wrap made of?
This blanket-type insulation is used to insulate rectangular and round heating, ventilating and air conditioning ductwork. It is manufactured with glass fibers bonded together with a sustainable plant-based binder system.
How much does it cost to wrap your ductwork?
The average duct insulation cost will be between $0.95 and $2.00 per sq. ft. installed, the cost will vary depending on a few factors which are discussed below, however r-values have the biggest impact and unsurprisingly insulation with r-values of r-3.5 are the cheaper, up to r-8.0 for the most costly.
Should I insulate my return duct?
Return air ducts only need to be insulated if they pass through environments that adversely affect the return air temperature. Exhaust air ducts normally do not need insulation. Insulation prevents condensation and dripping from ducts.
Should I insulate duct work?
Without proper ductwork insulation, you could be losing 10-30% of the energy used to heat or cool your home. A good level of ductwork insulation will prevent not only energy wastage, but also leaks, temperature drops, and condensation buildup.
Should I insulate my ductwork?
The ductwork in unconditioned areas, such as basements, floors, and ceilings is where ductwork insulation is most necessary. Cool air passing through warm areas in your home can cause condensation in the ductwork. Proper insulation levels can actually prevent condensation form occurring in your ductwork.
Should you insulate return ducts?
Does ductwork need to be insulated?
The ducts are exposed to the same cold, heat and humidity that exist on the outside. Insulating them is essential in colder climates, optional in milder ones and necessary in humid climates to prevent condensation.
How do you install duct wrap?
Fit the prepared section or sections of duct wrap insulation over the duct, making sure it fits snugly. Using a small amount of tape to hold one side of the wrap in place can make it easier to fit the rest of the material over the duct, back to the point where it meets the taped side.
What do you need to know about duct wrap insulation?
Duct wrap also provides a vapor retarder outer jacket (as an unfaced blanket or with an FSK, gray PSK or white PSK vapor retarder facing), which prevents condensation inside the insulating blanket or on the duct metal surface itself. They are available in 48′ and 60′ widths to reduce installation costs.
What kind of insulation is used in HVAC ducts?
Duct wrap insulation is designed for the exterior of rectangular or round sheet metal ducts. Once installed, duct wrap insulation continues to save energy throughout the life cycle of the HVAC system. Atmosphere ™ Duct Wrap Designed to wrap the duct, providing excellent thermal properties, energy conservation and condensation control.
Why do I need to insulate my attic ductwork?
The greater the temperature extreme between the air inside the duct and the air surrounding the ductwork, the greater your need for duct insulation. Unfortunately, so many houses — especially newer homes — end up with ductwork running through the attic.
How big is a fiberglass duct insulation roll?
All Fiberglass duct insulation rolls are 48″ wide, 3/4 lb. density fiberglass with FSK Foil facing, and sold per roll. Fiberglass blankets have both thermal and acoustical properties.
