    I think it can range from transitional to contemporary, ie: one of the linear ones may be ok, but in any case it needs to be "clean" looking. I don't know enough about the electric ones to say if ...

    Jamie, Remind us again where you are located.

    If using vinyl siding, you need to follow the manufacturer's instructions. I believe most products cannot be installed over furring strips.

    What style are you looking for? Craftsman cottage-y, farmhouse, transitional, traditional, or something else? Would your wife access an electric fireplace that looked and performed (mostly) like a ...

    Martin - Thank you. I appreciate your input. There's a good possiblity I'll use vinyl board & batten over cedar. Since vinyl board & batten has a much greater surface area sitting flat ...

    Fred, while I haven't used mineral wool in this application myself, as I prefer interior foam when I have to do basements, I did research the topic for a Fine Homebuilding article ...

    Dwayne, I had the same problem, had it discussed on a Q&A Spotlight here. Need to know where the humidity is coming from. In conjunction with the blower door test, it's useful to do an infrared ...

    The prices for the ERVs I gave above are installed prices, and with metal ducts. I fact, after my post I talked to the HVAC contractor we use in all my builder's jobs, and he said that a Fantch ...

    We install in all our houses Honeywell, Fantech and Panasonic ERVs, with capacities from 40-120cfm for $1000-1500. It covers pretty much all houses. Revised: This is an installed price.

    Martin, That was exactly my situation. A long delay between insulating and dry walling. Lesson learned. Thanks for the help.
  • Fred Williams | Nov 18,2017 07:48 AM EST
    Thanks Martin. I hope to hear from Mark or anyone else having experience with or thoughts on using this approach. Am I correct that mineral wool also has the advantage of being less vulnerable ...

    Dwayne, It's impossible to provide much advice unless we know more. The most important missing information is the interior relative humidity (RH) during the winter. Excessive air infiltration ...

    Jerry, Dana is right. You can't use a plumbing vent stack for a radon mitigation system. For more information, see this article: All About Radon.

    Michael, Follow Dana's advice -- in most cases, you'll want to install dense-packed cellulose in your walls. That will stop most of the air movement up your stud cavities (and lower your energy ...
  • Martin Holladay | Nov 18,2017 05:50 AM EST
    Michael, The main reason for the phenomenon that you observed is that there is no air barrier on the interior side of the mineral wool insulation. Even ordinary taped drywall would have been ...
  • Martin Holladay | Nov 18,2017 05:36 AM EST
    Fred, I hope that Mark sees your comment and provides his opinion. In the meantime, here's what I know: mineral wool panels have been used for decades to insulate the exterior of foundation ...

    Brian and Malcolm, This approach is called "the Bonfiglioli approach." To learn more, insert the word "Bonfiglioli" into the GBA search box, or read the original article on the Fine Homebuilding ...

    Dan, 1. Yes, 2 inches of XPS (R-10) is enough foam to keep you out of trouble in Zone 7, assuming 3.5 inches of fluffy insulation on the interior side of the rigid foam. For more information on ...
  • Martin Holladay | Nov 18,2017 05:15 AM EST
    Dana, You're right that I shouldn't have used the phrase "keep the sheathing above the dew point all winter long," since the phrase is technically inaccurate. Thanks for keeping me on my toes. I ...
  • Martin Holladay | Nov 18,2017 04:50 AM EST
    Reid, Since I wrote my 2009 article, the model building codes have changed, and many builders are now required to install residential ventilation systems. As you point out, however, builders' ...
