Insulating concrete

Hello Tom,
My house is 24 x 40. I have been thinking of ways to help with the heatingbill this winter.One thing I aim to do, is to insulate the concrete foundation from theground up to the clapboards. This distance is about 18" with 5 cellarwindows, 14x24. I have seen people gluing insulation on the concrete andthe other day at Home Depot, I located 1 1/2" insulation with aluminum oneach side, 4x8' in size. The setback from the bottom clapboard is approx. 2".� Would you recommend doing it this way or doing the inside? I wouldneed to take a lot of things down in order to do it inside.��On theoutside I would intend to apply a gray mastic to keep the concrete look.

Hi Harley,
It is preferable to install it on the inside, since there are no issueswith bugs sneaking in underneath it and it is protected from sunlight anddamage.If it is a big hassle to do inside, outside installation can be done. Youshould use styrofoam, cover it as you mentioned and install a metal dripedge as a barrier for bugs.
