I'm trying to create an inner shell for my garage in order to soundproof it and AAC came up. Worth it?
>>2991054My whole house is built out of this. It's great, easy to drill holes and insulation is not needed, the walls end up quite thick tho. If you're just after sound proofing I think other materials are better for this, some foam probably.
>>2991054You probably want panels of some kind.I think the aeration just makes it lighter for manageability with a higher R value—regular concrete is probably more soundproof and comes in panels (like, for bathroom tile backer)
Just do the dense - visco-elastic - dense stack like everyone else, it's the standard for a reason. Dense can be concrete or brick or drywall or plywood. Visco-elastic can be green glue, mass loaded vinyl or rebond foam.https://www.soundproofyourstudio.com/blog/how-to-soundproof-over-existing-walls-ceilings-and-floors
>>2991150Not just soundproofing. Thermal too.The idea is to goAACWood beams screwed onto the AACInsulation between beams.Spacer clips Drywall carried by spacer clips Mass loaded Vinyl Second layer of drywall Seal air gaps with green glue
there is a few tours of sound stages on youtube and hanging a rug off the wall appears in a lot of sound stages.
>>2991150>If you're just after sound proofing I think other materials are better for this, some foam probably.Fuck no. Glass or mineral fiber wool is for that.
>>2991758This. Mineral wool is absolutely superior for soundproofing and provides good insulation that cannot hold water.
>>2991787>that cannot hold waterbreathable insulation is actually a good thing, it helps regulate indoor moisture and improve air quality. just don't use non-permeable paint/plaster on the outside because dew will form under it, freeze and make the whole thing crumble and fall off.
>>2991802>freezeNot a problem in my area, bucko.
>>2991810you still shouldn't paint over it with acrylic paint or other non-breathable shit because the moisture will accumulate in your walls instead of freely evaporating outside, potentially causing mold and not helping you regulate indoor humidity without relying on ventilation

>>2991150What's your temperature range?
>>2991054>inner shell for my garagewhat is the existing wall?>>2991337>Wood beams screwed onto the AACyou will get better performance, both thermal and sound, by leaving a gap between AAC and wood
>>2991054>This nigga got air in his concrete Lmao
RAAC is all over the news here in Bongolia, and has been for a couple of years. All our schools and office buildings that were built in the 1960s were made from it, with the knowledge that the buildings would just collapse after 30-40 years and new ones would need to be built. Due to national idiocy, that never happened, and now we have countless scandals where schools and hospitals keep dropping bits of concrete onto children and sick people and pregnant mothers. So I guess my main advice to you is, don't put it in your ceiling.
>>2991054you mean aids-crete? i guess if youre a fag

>>2998573>make roofs out of rock foamwhat were they thinking
>>2998430That's only for the roofs and ceilings btw. Embedded in a wall, they last multiple times longer, especially if they aren't load bearing which we all know they are not in RC column construction, it's a fancy insulation material pretty much.
>>2991337why so much shit? just do like every modern european house>aac>styrofoam slabs>plaster>paintthat's fucking it
>>2991054redpill doesn't mean "tell me about" or "educate my dumb ass" you dickhead
>>2998800>Embedded in a wall, they last multiple times longer, especially if they aren't load bearingIt's so strong that it doesn't immediately collapse under its own weight? Wow.
>>2998602"it'll go well with the asbestos ceiling tiles"
>>2998573>xhe/xir used AAC as a structural materialohnononono ahhaaaahaha lmaooo ngmithat's like load bearing drywall
>>2998573>rebar>in porous concrete>on a roof>that is poorly maintainedwhat did they expect.
>>2991054you can DIY: https://www.youtube.com/watch?v=z4_GxPHwqkA
>>3003022To replace it in 30-40 years.
I enclosed my kitchen balcony to make it one room with that shitits basically lighter bricks, I wouldnt say its an insulator
>>2991802What? Not holding water and being vapor impermeable are two completely different concepts. Rockwool is completely vapor permeable and won't cause any issues with drying>>2991925What does painting the interior walls do to stop it from drying to the outside wall? Also who tf uses acyrlic instead of latex paint? But regardless both are like 5 perm anyways, which is still semi-permeable
>>3002776aac is fine as a structural material to hold your roof, maybe a second floorjust don't fucking make the roof itself out of it ffs
>>3004089>What does painting the interior walls do to stop it from drying to the outside wallnothing, if you don't live in places where it's wetter and hotter outside than inside most of the year. otherwise, mold, right on the back side of your semi-permeable paint expanding from there.
>>3004118Either way, this doesn't really sound like an issue with drying to the OUTSIDE.In hotter/wetter areas like you described, sounds like your just fucking up drying to the INSIDE with the paint lol. Vapor that condensates in the wall never dries to the humid outside, it comes in to your dry cold ac air and evaps there
>>3004182>Either way, this doesn't really sound like an issue with drying to the OUTSIDE.yes, if you don't make a vapor barrier using paint on the OUTSIDE then OUTSIDE will not be prevented from drying, thanks for noting this.>it comes in to your dry cold ac air and evaps thereit hugely depends on your ventilation and AC setup, centralized forced ventilation that dries all the incoming air at once will generally be fine but an old naturally aspirated house with an AC installed later might not.
>>3004211>if you don't make a vapor barrier using paint on the OUTSIDE then OUTSIDE will not be prevented from dryingWe're literally talking about interior walls being painted, what? My whole point was>What does painting the interior walls do to stop it from drying to the outside wallOriginally Anon (Or yourself, idk) said don't paint inside and create a vapor barrier that stops drying to the outside. Which we seem to agree, isn't how that works>it hugely depends on your ventilation and AC setupI mean yah for sure, I was thinking as a rule of thumb for modern(ish) houses with central air and insulation. Anything older that was meant to be completely air open like Victorian homes is gonna get fucked by basically any modern materials/methods.I mean look at Cape Cods, that was 1930s-50s homes with insulation and central air (at least heating) and they still fucked up how those houses wick away moisture.
