    While not exactly unusual, a gap between the foundation and mudsill is not a good thing either. It can be hard to pour a foundation perfectly level on top, and tools available in 1976 were less ...

    Bernard, This article and the sidebar links provide useful advice on this topic ( The bottom line is that air ...

    Coyote10, What is your question? Where are you located?

    Kasey, You can certainly do a ventilated attic, but it is still important to air seal. Moving the ducts out of the attic would also be a plus. Some homeowners run the numbers and decide to go ...

    I am assuming I would test attic floor with blower door. What result should I shoot for on attic floor?
  • Jon R | Mar 20,2018 10:29 AM EDT
    When it comes to air sealing (ducts or attic floor), be sure to actually test the results. Consider using blown in cellulose insulation.

    Hm, that is a good point. Thanks for the heads-up. This is exactly the advice I was hoping to get.

    Yes. In fact one company, Ecocor, offers it as a standard panelized product:, using I-joists instead of site-built Larson trusses. (I used to work there and ...

    Yes, I have gone through the Manual J. My loads are about 27,500 BTU/hr. My thought process is that the wood stove will handle the majority of the heating and that the mini splits are my primary ...

    I never lived in this house prior to remodeling it. I do not have any windows or doors facing west. I am leaning towards not spray foaming the underside of the roof deck and instead just ...

    The most recent information I have on the US phasedown schedule has a Jan 2020 deadline for insulation in refrigerators, etc., and a Jan 2021 deadline for XPS foam. There was no specific deadline ...

    Could we have an update on this important issue? It is 2018, several years since less damaging blowing agents were promised. Have these been adopted by the US insulation manufacturers? Are these ...

    Seth, Do you have a Manual J report?
  • Mike Spooner | Mar 19,2018 07:21 PM EDT
    You're right on the money. The quotes I've gotten so far have been in the $2,500-$3,000 range. Did you have any thoughts on the quality of the installs in the portfolio I linked to?

    Smokey, That profile looks like it has a lot of drying potential.

    Thanks Dana. I have worked with roxul before it's not bad to work with. I'll be taking my time as I'm retiring. I'll still price out the blown fiberglass and see how it compares financially to the ...

    Good topic. The AWG's rating is 700 circular mils per amp, which is very conservative, but the assumption is that wiring is in air and not in a bundle. The NEC has their own guidelines. AWG's ...

    R23 rock wool is probably cheaper than 2.2 lbs blown fiberglass, and might be comparable with 1lb blown fiberglass. R23 rock wool is as air retardent as 2.2lbs fiberglass, if fitted ...

    How many board feet (1" x 12" x 12") would it be for the 1" + 2" flash'n'batt, compared to 3" walls + 5" roof? At about 3000 board feet of HFO blown foam, a recent quote came in at about ...
  • Michael Maines | Mar 19,2018 05:56 PM EDT
    Yupster, that is/was my plan, figuring that we know the temperatures and RHs at which moisture will accumulate, and we can track it over time. I say "is/was" because I am having some trouble with ...
