We started doing exterior foam board insulation in 1999 when a couple of area builders said it could not be done. We are still doing this normally with at least 1 inch and sometimes 1.5 inches and caulking the seams and taping the seams as well. We start about 2 inches below the rim joist area if possible and go all the way to the top whether that is the gable peak or the sidewall. Doing this has provided us with us with very low energy usage for our rental property portfolio. Ironically, the very same contractor who said it could not be done has just built his first duplex in about 20 years using the same process. Amazing.

To prevent mistakes we need to be definate for every single location the the amount, kind and location of insulation required. The building inspecors need to be trained to be on site to check when the insultation is installed. These mistakes should NEVER BE MADE now that we have all this knowledge. Do we want these buildings to be durable?

What did you learn?
What did you learn?

Pest control companies, like a national one, say they won’t give a termite warranty if the crawlspace gets sealed, and then 2 years later that same pest company is sealing crawlspaces.

Ann, without greeting into a lot of questioning about your particular situation you might just want to check Dr. Joe’s comments and experience with his own basement.

As far as termites go — whether or not the risk is overstated or not may be irrelevant if you can’t get a pest warranty or termite report, as required by all mortgage companies. When I built my previous home in Charlotte, I consulted with two very knowledgeable pest control companies and adapted my design based on what I learned.

Jake (and Andrew) – I hope that you also respond to the GBA blog as it seemed few chimed in to counter the claims of ubiquitous damage. I had thought that exterior insulation (particularly when doing a deep-energy retrofit on a masonry structure) would be extremely beneficial, but the reports of invasive nature are very concerning.

@David Eakin-the naysayers have been around for years, and probably always will be. It doesn’t matter the subjext, someone is always there to cast stones.
While certainly not very long term or definitive, I have been building full ICF homes for over 12 years, and have not seen or heard of any of these troubles from any of our clients. This is with the foam going below grade-extending from footing to truss! I have to imagine that the risk is lower if the foam is used only on the above grade walls. Of course, it is necessary that one does not leave the foam unprotected.

David Eakin, I read the GBA
David Eakin, I read the GBA thread about exterior rigid foam. From that thread, and following the topic of exterior insulation for several years, I understand that people have concerns in some environments about ants in rigid foam. But I have not heard of concerns with the denser rigid mineral wool “boards” that are used for exterior insulation. I’d be very comfortable specifying mineral wool.

Allison: great demo, thanks for sharing it. Some pictures are worth a million words.

Hi,
I thoroughly enjoy reading your blog and often use it as an inspiration when I write my blog. Thank you!
I would love to share with you the configuration of our “Exterior Wall” for your critique.
