How would you insulate this garage/workshop?

[funny farmer]

Those look like 2x4 walls so r-11 is what you need, I would just buy the 8 ft. stuff and put it in over the horizontal studs and go back and run your knife over the horizontal studs cutting the insulation and then stuff it in the wall cavity. Then I would install 6 mill vapar barrier and sheetrock it. With the ceiling I would install eve vents and go over the cieling with 6 mill poly and sheetrock it, then rent a machine and blow in about 14 inchs of attic insulation.

1*The horizontal studs in the walls are a little unusual in my experience. How thick is that OSB skin? If they went with the real thin OSB,
2*I guess that would explain the horizontals as they didn't want the thin OSB to wrinkle/warp between the studs.

3*The vertical studs are the nailers for the siding.
Thanks,

1* 2* & 3* The wall has been built using a combination of Pole Building Construction and Stick Built Construction is why there are both horizontal and vertical studs.

Pole buildings have horizontal studs.
Stick built has vertical studs.

lhfarm ; Can you tell me why the walls were built this way?

As shown in this picture, the garage (and our house) is sided in vertical cedar siding. The garage was stick built with the 2x4s inserted as nailers for the siding. I'll check but I think the OSB is 3/4"

yea, exactly what funny farmer said!

other than that, what's up with that electrical work? why don't the wires run horizontal to the next outlet instead of up?

Did you also notice that all the 2x4s are facing the wrong way both for the The horizontal studs and the vertical studs?

 

[LBrown59]

The vertical studs are the nailers for the siding.

So then what is the purpose of the horizontal studs?

I assume you are refering to the horizontal 2x4s but why would they be necessary when the siding is already nailed to the vertical 2x4s?
I'm still puzzled as to why the vertical 2x4s were installed faceing the wrong way

Please explain what is the "wrong way" for the vertical 2x4s. I am mystified by this, they appear to be correctly installed to me.

Way back when, the horizontal 2x4s would have been called "fireblocks", and one of their purposes would have been to prevent the rapid spread of fire if the wall were finished out and not insulated.

I would call the "horizontal 2x4's" blocking. In some cases blocking at certain locations is required by code, for example several bays each side of a corner. In this case this blocking can be called a nailer. I did the same on my garage, it is 30 x 40, framed with 2x6. I put a 2x6 every 16 inches in between the studs to act as a nailer for my vertical pine siding, makes for a very stiff structure. To insulate, I simply used R-19 unfaced (2x6's) with 6 mil poly on top and then GWB, the ceiling I used R-30, 6 mil and GWB.

If I did my house and garage over today I would spray it with the expanding spray in insulation, maybe, I looked at doing 4 years ago when I built my house and it was prohibitively expensive, I couldn't imagine a payback, but that is when oil was $1.50 and appeared stable.

I've never noticed. Guess copper was cheap then.
