hey guys
I am putting central air in my house and my Lennox furnace is 17 years old so while I am at it my hvac guy is going to put in a new furnace also.
my furnace is in a crawl space and to save some money I am going to insulate my metal ducts myself. my main trunk is metal then all the take offs are flex duct.
my hvac guy is recommending I use a double bubble wrap with an air space and I was thinking of using foil faced thermax in 1/2 or 3/4 and cutting it to size and foil tapping it together.
just wondering what any one thinks is a good way to insulate the ducts
like I said it is in a crawl space and the metal ducts do condensate in he humid summer
thanks nicko
