You could probably save quite a bit on cost by picking a more practical material that doesn't need to maintain integrity at 3000°F or endure rapid temperature swings of several thousand degrees, though. Foamglas comes to mind (in fact, at a basic level it's pretty similar to spaceship insulation). I wonder if I could get Whipple shield siding somehow...

I'd consider putting in a solar heater for a swimming pool but that's a pretty specific use case and isn't cheap to do, unless you want 500+ feet of black garden hose on your roof

His Divine Shadow posted:Oh and we also combine this with an air circulation system that has a heat exchanger to extract heat from outgoing air and heat up incoming air. That's standard stuff in "energy star" or "green" construction around here. Code minimum in my area (which is fairly similar to Finland's climate) is around 400mm & 150mm, respectively, and is what very nearly everything gets built to because the average person thinks of "code" as a high standard to strive for, rather than the absolute lowest quality you're legally allowed to build. In warmer climates, you can also use an "ERV" ventilation system that not only exchanges heat between the incoming and outgoing air streams, but humidity as well, saving energy from dehumidifying air in cooling modes. canyoneer posted:I live in the southwestern US, and solar water heating systems work really well in this climate because we don't freeze. They're on every house in Israel. The big problem with solar water heating is that you can't resell the surplus. Even though you've got high efficiency on paper, you end up wasting a lot of it if you're reasonably efficient with your hot water usage. And with the advent of heat pump water heaters, solar water heating becomes even less compelling.

Also, the security system, while elaborate and effective for some time, eventually failed and is a huge liability. Your home insurance is going to be through the roof due to the risk of a wrongful death suit.

Still working on workshop plans. Since I don't plan on finishing the interior (no drywall), I need an alternate fire barrier. The local building office suggested using a stucco exterior, but from what I've read that's really labor-intensive to install. Does anyone here have a recommendation? The fire barrier would need to be 1-hour rated. A local contractor friend of mine suggested James Hardie products (looks like some kind of cement board system) or DensGlass products (fibreglass gypsum board), but I wasn't able to find fire rating information for either of them.

Is there a specific reason why you are avoiding drywall? The easiest thing might be to just use drywall. You'd only need to tape it, not float it out and texture it. (So it'd look like a garage) That isn't too difficult to do. Hardie board and such go up just like drywall and have to be taped just like drywall, but hardie board is heavier and harder to cut, and you use fiberglass tape and thinset to do the taping.

Amykinz posted:Is there a specific reason why you are avoiding drywall? Two main reasons to avoid drywall. First is that it covers up the wall cavities inside. Since I'm not planning to put in insulation, those'll be bare by default. This'll make making changes (e.g. if I decide to run a water line, or need to add outlets or something) easier, and also mean I don't have to dick around with a studfinder every time I want to put up some shelves or something. Second reason is that I'd like to have the ceiling be as open as possible. This is partly just because I'm a tall guy and thus like tall ceilings (and I have precisely zero tall ceilings in my house ), but more importantly, I have a couple of skylights planned that wouldn't be much good if they're covered over by a "proper" ceiling. Yeah, I know you can set up light tunnels and stuff like that, but those would interfere with using the ceiling joists to support storage areas. So basically I'd prefer if the fire rated stuff was on the outside of the building rather than the inside, so long as I can achieve the necessary fire rating. Are fiberglass tape and thinset significantly more difficult to work with than drywall tape and mud? Supporting the weight during installation is a potential issue, though it might be doable with strategic use of temporary shelf supports clamped to the studs or something. I guess that depends on if you can install top-to-bottom or if you have to do bottom-to-top. EDIT: oh, well, if hardie board isn't fire rated, then screw that. Hrm.

TooMuchAbstraction posted:Are fiberglass tape and thinset significantly more difficult to work with than drywall tape and mud? Yes. Particularly the thinset. TooMuchAbstraction posted:EDIT: oh, well, if hardie board isn't fire rated, then screw that. Hrm. It is dense enough that it transmits too much heat to achieve adequate protection. You need to be looking at certified material manufacturers assemblies. This is how you prove the fire rating using the provided materials......simply applying whatever rated material in whatever manner works for you is not enough. Here is an example: http://www.usgdesignstudio.com/wall-selector.asp Your AHJ will be looking for a document/cut sheet like this if they don't already know and recognize the material and construction type you are proposing, so be ready with one in your plans.

TooMuchAbstraction posted:and also mean I don't have to dick around with a studfinder every time I want to put up some shelves or something. A few extra points to make about drywall... 1. If you don't finish or paint the drywall, you'll have all your screws visible but covered with a line of drywall mud. This makes it super easy to locate your studs when you want to hang poo poo. You really don't need much ability to do the first pass on taping if you're not going to texture or paint it. If you can put peanut butter on your own sandwich you can figure out taping. You'll be doing something like this: 2. You could try to drywall above the rafters so you have a 'cathedral ceiling', and then you get your storage space and easy skylight instillation. 3. You can install bottom to top, then you just sit the next sheet on top of the sheet underneath. A drywall lift would make things much easier for you and aren't that expensive to rent.

Amykinz posted:A few extra points to make about drywall... Actual drywall installation doesn't scare me, no. I've done it before; it's a bit tedious but hardly difficult especially if you don't care much about making a smooth final surface. Did you mean applying drywall on the top or underside of the rafters? On top would be a little weird because then it'd go rafters -> drywall -> presumably some plastic sheeting -> plywood -> shingles, and if the drywall ever got water damage you'd have a devil of a time replacing it. On the underside would probably work okay, though I'm unclear on how you'd manage the area around the ties joining the rafters to the top plate and ceiling joists. Is this one of those things where any "holes" in the barrier render it useless, or is it okay to just do a best-effort to cover as much as possible?

TooMuchAbstraction posted:Is this one of those things where any "holes" in the barrier render it useless, or is it okay to just do a best-effort to cover as much as possible? If your best effort is seamless mud coverage that completely seals the interface, yes. Painters tape is your friend when doing this with rough hewn beams. It's not at all out of the ordinary. Yes, it's a pain because of all of the cuts and jigsawing it up there, but it's far from unique. FYI, I'm gonna bet you'll need to do this twice. Your AHJ is probably gonna want double 5/8". And the smart way to do that is to stagger the cut ends.

Motronic posted:If your best effort is seamless mud coverage that completely seals the interface, yes. Okay, good to know. Thanks. I wasn't planning on using rough-hewn beams (just 2x8x16' ceiling joists, 2x6xsomething rafters). I guess I don't really need the joists to be dimensional though, so there's some opportunity to save a little money there. I assume the reason to do it twice is to make certain that a messy, hard-to-cover area has some degree of redundancy built in? And yeah, if you're doubling something up and then aligning the cuts then you're just wasting a lot of effort. I know at least that much!

TooMuchAbstraction posted:I assume the reason to do it twice is to make certain that a messy, hard-to-cover area has some degree of redundancy built in? Not really....it's to get the fire rating. The typical 1 hour fire rating is 5/8" with studs and then 5/8" on the other side. Some inspectors will accept two sheets of 5/8" on one side as an hour rating, because double 5/8" then studs than double 5/8" is an accepted 2 hour rating. But to be hones, in the 5 minutes of searching I've done with google (haven't broken out the actual code books) I can't find anyone who rated double 5/8 on one side as anything. I mean, sure....it's got to be more than an hour, but if you can't come up with something that's been tested and the AHJ doesn't go for it you're pretty much screwed. This is the kind of thing you should ask in advance and in writing.
