[Greenbuilding] insulation vs. air sealing

[Kathy Cochran]

Hi all,

I am getting ready to have insulation blown in to my attic.  What exactly is
the "stack effect"

And, now in my county anyway, it is required to have roof caps that are
ventilated.  So, how does this impact on sealing up all "leaks" in the
attic?

Thanks,

Kathy Cochran

Corwyn and Nick,

Do you have a suggestion on
How to test the stack effect ? 
I could do a before and after. 
My hunch is that the stack effect decreases if you air seal attic before
blowing insulation and increases If you do not air seal the attic before
blowing insulation.
