    Bill, Thanks for providing the information on how the archive came to be. And I'd like to join you in extending thanks to Mike Jackson for his work. It's a wonderful resource, and is a great ...

    The archive that Martin linked to in comment #5 was largely the work of Mike Jackson. Mike has retired from his position with the Illinois State Historic Preservation Office, but he remains very ...

    Bic, First of all, can you tell us your name? GBA has written lots of articles on this topic -- enough articles to keep you reading for at least an hour. Here are some links.

    Sebastian, This isn't brick veneer. The wall you are describing is a structural brick wall -- "there is no wood framing." Now that you know that fact, you'll have to abandon the plans that ...

    Phil, If you want to create a vented roof assembly, all of the insulation has to be on the interior side of the vent channel. If you invite outdoor air between two layers of insulation, as your ...

    User-7026765, First of all, can you tell us your name? It's hard to keep a shed from freezing when outdoor temperatures "dip to the 20s and occasionally could dip lower" unless the shed has a ...

    Emerson, In most regions of the U.S., residential customers can't choose their electric utility. A utility usually has a government-regulated local monopoly. That said, some large commercial ...

    It is a sad reality that the things we obsess about on this site have not proven to add value to a home when you go to sell it yet. I wanted to buy a home with solar already installed zero homes ...

    Andrew, It would be really interesting to know what percentage of houses damaged during floods had taken even rudimentary design consideration of the possibility they would be affected.

    Building up is good. I would still think about what might happen if things get wet. Two recent articles that you may be interested in reading: 1. Ted Cushman article at JLC, Flood-Hardy ...

    Surely it's fairly straightforward? If PV doesn't increase the market value of house in a certain area, the appraisal will reflect that. For now, whatever its other merits, solar isn't a feature ...

    P.S. I own the solar, it's not leased.

    Finally got the house. And here is a surprise… so the wall is brick veneer, then air gap, then another layer of brick veneer, air gap, and plaster walls mounted without framing (not sure how, will ...

    I'm revisiting this roof assembly to avoid foam, both sprayed and rigid, if possible. A roxul tech recommended using Roxul Rockboard 60 rigid insulation board in place of polyiso on exterior roof ...

    The stuff I was fighting was similar to Cabot's Quilt, but with horse hair rather than eel grass between the sewn heavy kraft sheets, and much wider- about 10' wide (full height in the stud ...

    Wow, thanks for the link that that archive, Martin. That could be many hours of entertainment. I found brochures from two "reflective insulation" companies, and they were generally considerably ...

    Going with the Zehnder 550 with the in-line heater, seems worth the premium compared to anything else.
  • Charlie Sullivan | Feb 23,2018 05:25 PM EST
    Some more tidbits on the history of the radiant barrier approach: According to the Insulation Handbook by Richard T. Bynum (2001), reflective metal surfaces for insulation were first patented ...

    Thanks for this perspective, accurately reflecting what has been learned, as well as as showing what has been known for many years. One thing stood out as a mystery. Aluminum insulation? Like ...
