BUILD THREAD 36x48x14 Shop Build Update 2/20/2024, Tire Machine is Finished!

IMO not doing it is underkill. I'm looking at using zip (maybe zip r if I'm feeling frisky) sheathing on my upcoming house build and that's the idea, seal it up nice and tight. With that alone, you quickly approach passive house standards.

While I agree, I want more R-value. I have a local company that air sealed my new house (foam, caulk every crack and air doored it) and used high density cellulose in the walls, I have an R23-26 in the walls, with R-58 in the ceilings. The house has 2 air changes and hour, almost too tight, with the air door test. The bathrooms and range hood vents keep it from being too tight. And I had a 3500 sq ft home done for less that it would cost to spray foam the shop for way less r value but the same air sealing.

Sooooo, I plan on 1.5" foam board between the girts and trusses, foamed, caulked and air sealed, I'll air door it to ensure no air leaks. Then possibly the same high density cellulose, as I am waiting on a qoute in case prices went sky high (possibly R-21 batts). I'll end up with R-25 plus walls and R58-65 ceilings. So I'll have more than double the R value of spray foam for way less the cost.

The air sealing is key, so alot of attention will be spent there.

I only have electric and propane available, and neither are cheap, so the better I can get it insulated, the better.

I agree with the sealing in general, the sealing was my point regardless of what material you use for it. If the house gets too tight you just add one of those air exchange dealies anyway. I'm really not sure what I'll do for the pole barn just yet since they don't get sheathed like a house and foam is so retarded expensive.

Foam really is soooo expensive! I have my Hilti gun, will buy some hilti foam and have at it with the foam board, Supposed to get some 1.5" foam board next week. Picking up the wire for the slab this weekend. I'm on marketplace everyday to buy what I can at a deal to keep costs down.

I wish i did this sh*t in 2019 before I deployed, but, I had to deploy, lol

Yeah, but because you deployed you were likely able to stack more cash aside for this build right?

Hell no, it paid off the house build credit debt! lol, I wish I could have stacked it for this though!

There is a local guy to me that sells used 4x8 sheets of 2" foam. They are removed from commercial building roofs I guess. He has some hookup. Usually gets it a tractor trailer load at a time. It is paper faced polyiso foam sheets. I've got half of my garage ceiling done in that. It was $12/sheet He sells out the same day he gets it usually.

That's a deal! I'm driving to VA, 1.5hrs, to get some at $18 a sheet to do the the walls and flat ceiling.

Progress from Friday, I was super excited to get home last night and see how the crew made out! The doors still need to get installed, but the building is up. I have the gutter guy here as I type installing one piece gutters and downspouts.

Sorry for the glare.















I picked up concrete wire mesh panels this weekend from a guy close to the base, 5'x10', $10 a panel. I am working on scheduling some deliveries of 57 stone and shale for the "road", then I need another truck or 2 of compactable fill for the interior. Currently shooting for May for the concrete. Give everything time to settle, dry out, and for me to build up the road to hold the weight of concrete trucks.

Is that a vapor barrier between the girts and metal siding?

No, that is house wrap.
