How do you calculate duct insulation?

Most duct insulations have a K value of 0.24 btu.in/ft2/hr/°F which is the thermal conductivity of the insulation at 1″ thick. If the insulation is 2″ thick, divide the K value with the thickness to get the corresponded thermal conductivity. For instance, 0.24 btu.in/ft2/hr/°F divided by 2 inch is 0.12 btu/ft2/hr/°F.

What is a plenum on an aircraft?

An aircraft engine cooling plenum is an enclosed chamber or container that is used to hold air at a pressure that is higher than the surrounding air. They work to stabilize the pressure of air to provide more even distribution.

What is the difference between R6 and R8 flex duct?

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.
