Insulating Stone Wall

I have an old house with a stone basement. I would like to insulate it as it is very cold. We live on Lake Huron in canada so it gets cold in the winter and very moist in summer. Our de-humidifier in the basement runs throuhout the summer. The walls above the stone are brick & plaster / baloon frame so it looks like blown in cellulose is in order. I would appreciate any ideas on how to make this place warm. regards

stone found.

As long as the stone walls are dry, I would insul. the basement in same way

as modern construction. Place a plastic vapor barrier over the stone wall, you

can use silicone caulk to fasten to stone walls. Leave an air space between

the foundation and a 2 by 4 stud wall in which you can fasten rolls of fiber-

glass insul., with it's own vapor barrier exposed to the interior of the base-

ment and then fasten 1/2'' drywall to finish. Leave a gap, about 3/8 '' below

the drywall to the basement floor, to prevent moisture wicking up into the

drywall. Oh, and keep the humidifiers humming, you'll still need them.

foam

Typical foamboard is a permeable material and won't take the place of a

vapor barrier. The poly faced foam is not really designed for a damp location.
