    Craig : Is replacing the attic unit with a (right-sized) heat pump something you're considering? It's not unusual for gas furnaces to be more than 3x oversized for their loads, and for air ...

    I would have guessed that site/topography would be a significant factor. For example: " increase of 260% in the wind load that a structure on top of the hill would experience relative to ...

    Yeah I would have 3 inches of polyiso on the roof deck so around ~R17 and then I have like I said about 6 inches of blown rockwool between the joists in the attic so somewhere between R16-21.0 ...

    I haven't seen any additional anchor support, beyond what comes with the panels, on installations here in the earthquake prone PNW. It's probably a similarly neglected aspect of the process that ...

    Walta, the photo is not my building. It is of the truss and purlin system I want to use to have exposed ceiling. I currently live in a post framed house and my electric bill is usually a little ...

    If GBA readers don't want to be held in suspense as they watch a video, the product that Richard is talking about is called Link-Seal. It is manufactured by GPT Industries. Here is a link to ...

    I was glad to see that the PV facility on St. Eustatius was reported to have survived last season's hurricanes in good condition. (See the map below from RMI's report -- the St. Eustatius facility ...

    The best products I've seen so far . Have not had one issue with these .

    account economic productivity. CO2 per GDP is probably a better representation.

    User-7039450, Below is an illustration that shows what F1 and F2 refer to. The illustration comes from this Simpson catalog page:

    User-7039450, Malcolm is correct. In Canada, o.c. stands for "on centre." In the U.S., however, o.c. stands for "on center."

    Alan, Cellular window shades (which are mentioned in the article) definitely work. They keep out a good fraction of the solar heat gain in summer and help retain heat in winter. More information ...

    Thank you, Malcolm. The practical argument should be persuasive--if ever needed.
  • Malcolm Taylor | Jul 16,2018 12:23 AM EDT
    O.C. is "On Centre". It tells you the spacing of the bolts. So every two feet would be 2'-0" oc. DF is Douglas Fir. SP is Spruce-Pine

    Thank you Walter and others. I have considered just framing out the space and directly fastening the metal siding to it. Then spray foam the inside of the metal siding like a pole barn. This ...
