Adding more attic insulation cost effective?

And a couple of illegals would make it even easier

Yep. The idea is to block any gaps that occur between the existing bats and the trusses/rafters.

What kind of ductwork are you talking about? Ductwork made of Duct Board, should be sealed with something like RCD #6 Mastic, and not tape.

What connections are you talking about?

What do you mean by "foam sheets"? Are you talking about the foam surround for outside electrical outlets?

I prefer Gonesh # 8 :)

The very best thing to do is, throw the batts away and replace them with at least 5 inches of poured poly foam. Batts are not a good insulation as the air and water vapour pass through them. What makes poly foam work is, it fills all the gaps and spaces making an airtight filling. It is the gaps that let the air move in and out that carry the heat. Fix the gaps, solve the problem.

If there's a backing layer, to a pretty decent degree, yes.

Fiberglass is excellent insulation but it it does need an air barrier in conjunction as the point that air will infiltrate through is correct. I'd recommend ensuring there aren't air leaks, however, rather than removing the existing insulation as the more cost effective solution.

I'm not looking for any argument. I made a comment about the correct way to seal ducts, and asked two serious questions...if you don't want to answer them, fine.

Sorry you took my post the wrong way.

You obviously have your mind made up and are looking more for an argument than information.

I will put it as simply as I can for you:

Insulation is not the only thing in the system. Check everything, make everything right, and your system will work more efficiently.

There.

Did you get THAT?

No?

Sigh ............
