Insulating Duct Work

I live in Pittsburgh, Pa. and I'm wondering if I should insulate the duct work in my garage. And if so, is the foil bubble wrap a good option? I know this stuff recommends some space for air when applying it. Unfortunately the way the duct work is positioned against the ceiling that might be tough on top of the duct.

Any advice or suggestions is appreciated.


Re: Insulating Duct Work

Usually the thickness of the bubble wrap is what is used to give an air space then wrap over the strips, (air is your best insulator) cut strips from the roll or you can buy them precut. When doing installs most HVAC Cos. use the fiberglass Insulation but what you are using is fine as long as you use the strips, it about doubles the R value.
As for should you do the insulating, it's only to your benefit and will save energy. Good luck!!! :)

Thanks Sten!

Hopefully I can squeeze the wrap up in between the duct work. It's an odd setup with how close it is to the ceiling, and an i-beam on one side.
