The insulation is (9/16″ to 5/8″) thick with large single bubble insulation in the center, sandwiched by two thin layers of single bubble insulation. Each roll of insulation includes two rolls of spacer strips. In order to achieve the R-8 value, the spacer strips must be used and placed every 2′ on the ducting.
Is R8 insulation good?
R8 ducting uses thicker insulation than R6 ducting. This means that if you were to do air conditioning installation using R8 ducting, you get better insulation than if you are using R6 ducting. When it comes to efficiency of heat insulation R6 ducting is less efficient than R8 ducting.
What is the R-value of duct insulation?
R-value of 3.5 is required for buried ductwork and ducts installed in an unvented attic with roof insulation or in an unconditioned space (including both ventilated and unventilated crawlspaces). There are no R-value requirements for ductwork installed in an indirectly conditioned space.
What is R6 duct?
Insulated Flexible Duct R6 Silver Jacket is used in standard Heating and Air Conditioning (HVAC) systems and some venting applications. The duct has R6 insulation which contains 33% more insulation than the standard R4. 2 product. This additional insulation provides greater thermal efficiency to save energy.
How thick is r6 duct insulation?

What is the minimum R-value for duct insulation?
“Supply and return air ducts and plenums shall be insulated with a minimum of R-6 insulation where located in unconditioned spaces and where located outside the building with a minimum of R-8 insulation in climate zones 1-4 and a minimum of R-12 insulation in climate zones 5-8.
Is R6 or R8 better?
R8 ducting is composed of thicker insulation than R6 ducting. That means if you have R8 ducting in your HVAC system, your ducting is better insulated than if it consists of R6 ducting. R8 ducting is more efficient at heat insulation than R6 ducting. R8 ducting reduces energy loss by about 2 percent.
How thick is R6 duct insulation?
What type of insulation is used for ductwork?
fiberglass
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.
How do I calculate how much duct insulation I need?
Measure the running foot length of the duct work to be wrapped and multiply that by the square footage of the duct to calculate the square footage of the duct work. As an example, a 6-inch duct will have a 3-inch radius. 3 inches squared is 9 inches. Multiply 9 inches by 3.14 to get 28.26 square inches.
What insulation has highest R value?
Vacuum insulated panels have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch.
What insulation is best for ductwork?
fiberglass insulation
When insulating HVAC ductwork, use a foil, faced fiberglass insulation with an R-6 or higher R-value. Use the type of metallic foil duct tape recommended by the insulation manufacturer to seal and hold the insulation in place.
How thick is duct insulation?
Some home centers sell special duct insulation: two-inch-thick fiberglass with a facing of aluminum foil. Foil-faced fiberglass or mineral-wool wall insulation, which is 3-1/2 inches thick, also makes excellent duct insulation if there is enough space around the ducts for the extra thickness.
What is duct insulation made of?
Fiberglass: Fiberglass is the most common insulation material. Cellulose: Cellulose insulation is made from recycled paper products. Foam: Foam insulation may be made from polystyrene, polyisocyanurate or polyurethane, which are all types of plastic. Mineral wool: Mineral wool can refer to either rock wool or slag wool.
What is duct board insulation?
A duct board is a common form of heating and air conditioning insulation made out of fiberglass and a thin layer of foil. Each board typically is 1 to 2 inches (2.54 to 5.08 cm) thick, and several boards can be assembled together to help airflow and maintain temperature.
What is an exterior insulation system?
An exterior insulation finishing system ( EIFS ) is a type of building system that provides exterior walls with an insulated finished surface and waterproofing in an integrated composite material system.
