foam insulation GENERALWTF is the latest word on foam?WTF foam done in past is now a nightmare and why? causing dryrot by trapping moisture? fire? cancer?Any you'd recommend today?WTF can't someone invent a nice, child-safe, DIY, non-toxic, cheap, non-problematic, breathable, non-flammable, etc, "universal" way to use foam, including injecting into fairly small holes, like 1".I'm thinking a combo of vinegar and baking soda to make it foam, and WTF knows what "base" material, but add something not too toxic to prevent "biology" from happening, and use a Shop Vac in reverse and small nozzle to inject or spray.Maybe whip air into the mix like whipping cream, with wisk attached to drill in a 5gal bucket with a hole in lid to prevent spray.Should be able to inject, spray or trowel, should also function is quasi glue to give panels extra strength if applied during install.
>>3014576>Any you'd recommend today?pic. when batt can't be used. Spray foam should be used only if nothing else works, and for filling holes around pipes and such.>>3014576>I'm thinking a combo of vinegar and baking soda to make it foam, and WTF knows what "base" material,cool thread, kid
>>3014576I've always thought quonsets should sandwich insulation between inner and outer metal layers. Keeps foam integrity up, makes wall 2x tough.
>>3014591literally building one right now, and that would be a bad idea. They are strong as fuck already. Built for Florida. Best way is to just fir them out bolting strips to the hut and using bat. Can't hang pictures on foam like Ai slop pic.
<deep nose inhale>AAAAHHHHHHHHHsmell that, anon? thats the smell of effeciency. 18°C ΔT @ 43° ootside dry bulb.
>>3014601oh my. should have done cheap h-tech panels

Anyone ever try those DIY spray foam kits? Might consider giving one a try sometime. Had some fiberglass skylights in the shop. They degraded in the sun over time and ended up just pulling them out and putting tin over the holes, but they aren't spray foam insulated like the rest of the shop roof, so I know it's losing heat out of those areas big time. Also just bought one of those re-usable professional spray foam guns that take the bigger screw on spray foam canisters tonight. Can't wait to give that a try.

>>3014601Nigga that's formaldehyde, even in the totally "not chinese" components that are "totally 100% formaldehyde free"
>>3014576Brainlet here so go easy on meCan someone explain the logic of insulation to me? Isn't air a good insulator? AFAIK that means it doesn't conduct the heat very well. Why do we need even better insulators?
>>3014992>Isn't air a good insulator?It is, but it's also a fluid. It doesn't really matter how well heat is conducted within it when a given mass of air can simply move itself and its heat somewhere else. Almost all insulation is really just trying to keep air in place without conducting too much heat on its own.
