BSC, Insulating Brick Walls

Good Morning,

Read this a few days ago, buildingscience.com, thought folks may be interested, or not.

BSD-114: Interior Insulation Retrofits of Load-Bearing Masonry Walls In Cold Climates




FYI, I have no connection with BSC. The point of view
expressed in the article is that of the authors.

    Thank you

    This is an excellent article. I tried and tried to find something like this when I needed to "fir-out" walls for my kitchen (to allow me to run the required electrical circuits). My place is a 1923 grocery store with 3-wythe brick and 1" painted plaster on the interior.

    Since I couldn't find any information I winged it and ended up pretty much as the article describes but with rigid foam instead of spray foam.

    I did leave a 1/4" gap between the foam and wall, which based on the article I shouldn't have, but I'm in Colorado where moisture is not really much of an issue.

    I do plan to make sure that my foundation drainage is good and take a look at the window corners to make sure they drain properly; as the article suggests.

    Thanks again....
