    Andrew -- Did your Sense ever recognize your heat pump? Or is the pattern of power consumption just too variable?

    When place at an intermediate layer the smart vapor retarder is experiencing a higher relative humidity than the indoor air, since it's at a cooler temperature. (RH rises when you cool a body of ...

    I was planning a 2x3 service cavity on the inboard side of the second wall with a smart vapor retarder in between, and R12 fiberglass bats pressed into the 2.5" service cavity just for the sake of ...

    Brian, The space between the ceiling joists usually contains insulation, so your suggested 1x4s would divide the insulation depth into two sections -- below the subfloor and above the subfloor. ...

    Also note: "The good news is that the air handler is powerful. In the summer it cools the whole duplex in 15 minutes with the AC." That's actually BAD news, because it means the AC (and ...

    For those that want to steer clear of this issue in an abundance of caution (or who have contractors who demand it), can some sort of decking be applied to the top of ceiling joists to support the ...

    J. Cryder, When a forced-air system has fundamental design issues, the fix isn't easy or cheap. In your case, your supply registers should have been installed in the floor instead of the ceiling, ...

    Having the two units work in tandem is more efficient than independent cycling, since when only one of the heads is running it would have to run at a higher blower speed to be able to take the ...

    Jerry -- What is IDT? Fujitsu does not have the "follow me" feature -- the temperature is measured only at the unit's air intake. Calum -- I will wait until the outside temperature is above ...

    Jerry, Thanks for the input. I will have an unvented insulated rafter assembly so I would have room to run ducts if I could find a trustworthy contractor. I was mainly interested in the wall ...

    I don't have any experience with the interlocking floating vinyl tile products. I would think it would require an extremely flat slab to work without adhesives, but don't really know.

    Installing a layer of OSB directly under the wallboard would also work as the "smart" vapor retarder, and may be easier to construct than Lstiburek's exterior-side-of-interior-studs approach.

    If you put the return at the ceiling level and the supplies are at the ceiling level it will just short-circuit- all the flow would be happening in the upper 2-3' of room air, which is the ...

    Paul, Thanks for the link. You'll get no argument from me on the fact that capitalism is driving climate change. As Kim Stanley Robinson noted on the "On the Media" show I discussed, "Good people ...

    Martin, Thank you for the post on this topic. I think we have to think more critically though about conclusions like "we have already injected so much carbon dioxide.....". There is actually no ...

    How did you deal with electrical boxes in the OSB? With drywall you can use a rotary bit to cut them out when the sheets are hung.

    Masonry Technology Inc also offers a 1/8" rainscreen that is less susceptible to compression & "sponginess" during installation than some of the entangled filament products. ...
  • Malcolm Taylor | Jan 15,2018 11:31 AM EST
    Jerry, if you have "a lattice of flat wise 2x4s", don't you end up with a series of 20 1/2" squares 3" deep on the ceiling connected to one another by 1 1/2" gaps? Will your low profile ducts ...
  • david flinn | Jan 15,2018 10:59 AM EST
    Hi, Thanks for the kick to re-read the great article about Rainscreens. I found that Keene Driwall comes in a 1/8" width option so I'm going to look into that. Another option is the use of ...
  • Kathleen J | Jan 15,2018 10:20 AM EST
    Martin, yes. It is in the plans, and already purchased Slicker Max as our rainscreen, along with the 2 layers of WRB, and a weep screed at the bottom. The only thing I cannot wrap my head ...
