Response to Bruce Johnson
by Martin Holladay, GBA Advisor

Bruce,
Q. "What thickness of foam?"

A. In Zone 5, the minimum required R-value for exterior rigid foam over 2x4 walls is R-5. For more information on this topic, see Calculating the Minimum Thickness of Rigid Foam Sheathing.

Some of your other questions are probably answered in this article: How to Install Rigid Foam Sheathing.

If, after reading these two articles, you have further questions, I urge you to post them on our Q&A page. (If you post a question there, more people are likely to see your question and to volunteer a helpful answer.) Here is the link to our Q&A page:

Exterior Foam Retrofit (keep existing windows)
by Bruce Johnson

I have 2x4 exterior framing with paper faced fiberglass batts covered by house wrap then 1/2" polyiso,then vinyl. My plan is to remove foam and house wrap from exterior. Fix or replace fiberglass and air seal penetrations, cover with osb and tape seams, cover with drainwrap, cover with at least 1" of rigid, then reuse existing vinyl or replace, possibly use some kind of stone or brick on the front and the rest vinyl. My main concerns are getting the door and window openings to work with the extra depth of the foam. I would like to keep my existing windows in place. How do I seal and flash them properly with out removing them? What thickness of foam and what kind do you recommend? I live in zone 5 (Southwest Mi). I thought about using xps and then reusing my 1/2" polyiso over that. Thank You for your time.
