Insulation affects exterior masonry properties

[mgbinspect]

Hey Kurt, Bill and Jim,

Here is a paper you may all be interested in regarding how insulation added to the interior wall affects the properties of exterior masonry.

It's the first I ran accross and I'm sure that better studies can be found.

I hope this is what you needed, Kurt or at least starts you in the right direction.

There certainly seems to be an infinite number of considerations when renovating an old structure. For every action there is a reaction.
