Hi,
Poor insulation costs more energy making you poorer!

Yes, that is why I asked the original question. I want to get the best that
I can afford. I understand it won't be like the rich folks have but I hope
it is better than what they originally put in this place when it was built.
This is not a severe climate like when I lived in New England with 30 below
in winter and also not like when I lived in Arizona with 120 degree
temperatures in summer. Middle Tennessee has a mild climate, an occasional
zero degree day or two but the norm is in the 20's during the coldest part
of winter and very often in the 50's. I don't have central heat so it's easy
to save by not heating the bedroom during the day and then not heating the
livingroom and kitchen at night.

Hi,
Fiberglass loses R value when compressed. So in a 2X4 cavity snug fit
fiberglass will have about R12. Rigid styrofoam has more R value but it
costs more. Also sealing all the air infiltrating gaps is good idea as
well. Aand vapor barrier.
good luck,
Tony
