Anyone have any experience with light steel framing? I'm trying to find some solid resources to design and build a tiny home using light steel on a pier foundation.
The thermal conductivity would likely be a beating on your insulation. I wonder why one wouldnt stick to lumber in this case. A proper thermal break may be required if you live in cold climates.
I might be a retard but this seems like it would be really difficult to fasten any drywall, outlet boxes, any other shit that you can normally screw to a stud quickly.
>>2439501I believe this is what the fine thread drywall screws are for.
>>2439501It's your typical commercial build pretty much. Just as easy, if not easier especially the headers. They're all laid out with passthroughs and predrilled holes for outlets, ect.Practically no insulation as most times the full front wall is glass anyway. It'd work for a house, just have to keep in mind they aren't designed to last very long. Depends where you are I guess.
>>2439203>Anyone have any experience with light steel framing?I'm living in house made out of it.What can I say. Thermal bridges are a thing, fastening heavy stuff is questionable sometimes, but in general kinda similar to wood framing, except you don't nail, but screw shit. >>2439501>drywallThey make special screws for shit, so it is not such big of a problem>outletsIt might get tricky sometimes.
>>2439714How? Sip panels? Where is the connection to the frame? Where is the thermal break? You can't just say "external insulation". Most of the time these steel structures have a ton of glazing in conjunction with concrete precast panels and very little insulation on the outside of the metal.
>>2439479Just coat it all in a few mm of spraycork, ez thermal break
>>2439710Bridging is easily fixed with Spacetherm CBS strips
>>2439873Dunno, I think external insulation is kinda better.But in my climate it is ok
>>2439877I meant between the beams, and along the roof trusses, it's only a few mm thick rolls
>>2439780Can't you just put rigid foam panels on the outside of the steel
>>2439923On what? The rigid foam produces a solid water proof barrier...
>>2439925Do you understand what condensation is?
>>2440312No I am stupid
>>2439203Who ever thought this was a good idea was an absolute retard.
>>2439923>>2439780>Most of the time these steel structures have a ton of glazing in conjunction with concrete precast panels and very little insulation on the outside of the metal.For residential, the entire frame is supposed to be inside of conditioned space. The residential design guides for LGS use shear members or shear panels to get rid of need for structural skinning,then wrap frame in non-permeable barrier, then use something like semi-rigid rock-wool or foam exterior bats to get full R-value on the outside of frame, and then seal and skin over the insulation. the connection to frame for the skinning varies system to system, but you're right, it's much more complicated and fiddly. anything you save in labor and complication by going to a Track-and-rail system gets eaten up by your exterior assembly.Some of the prefab-panel companies recommend the R-20 ZIP panels, so you end up with an OSB exterior anyways. I've seen a few projects go with rigid foam overlaid by DensGlas; some of the rigid foam panels come with plastic inserts on the on exterior surface for attachment to a skinning system and apparently GP has a couple product lines and partner firms that they recommend for residential, but it's such a marginal market for them you generally have to chase down the info from their reps.
Personally, I'd just build it out of wood.
>>2441229yup wonder how many times more expensive it is compared to wood, that's allot of steel
>>2442503Prolly the same price
>>2442503Under normal conditions the structural LGS members - like 16-14 gauge - come in about 15% more than comparable wood in similar dimensions. Haven't been normal conditions for the past 2 years now, so who knows. Spot prices for lumber are still up from 2019 and Steel is about even.
This is a great idea. If your house burns down, the structure will remain and you will be able to rebuild quick, unlike with a wooden cardboard house.
>>2442881>16-14 gaugeThey are usually 0.8 - 1.2 mm which is more like 18-20>>2442885Shit is cold-rolled, you're fucked basically, it will lose strength.
>>2443140But but jet fuel can't melt steel beams!
>>2442503>how many times more expensive it is compared to wood25-50 percent more
>>2443140>Shit is cold-rolled, you're fucked basically, it will lose strength.It'll be fine, stop listening to the screeching enginiggers who say it'll LE FALL DOWN ON YOUR HEAD!
My grandparents built a new home with a steel frame in the 90's. Don't have to worry about termites or rot but you'd get fuck all reception for mobile phones, cordless landline phones, radios, and later wifi inside the house. Drove them nuts so the next place they built in the late 00's they went back to a wooden frame.
>>2443664>you'd get fuck all reception for mobile phones, cordless landline phones, radios, and later wifi inside the houseCan confirm, my garage is built using steel framing and it absolutely destroys my cellular signal inside. Like 1 bar, or sometimes zero, where outside the garage I get 3-4 bars. And that's just a simple 4-walled building. I can't imagine if it were a house that also had a bunch of interior walls with steel in them too.
>>2442885>>2443211>>2443650A fire will cause the whole structure to flash rust, and they studs will probably fall apart with how thick the rust will be and how thin the steel is.>>2443584>>2442881Steel has been cheaper for very long stretches since 2020 stud for stud, and are roughly the same rn.>>2443841>>2441380>>2439203Biggest problem stopping me from using steel is windloads in florida, specifically hurricane ratings is a lot harder to get info on with steel, where you can just screw studs together over and over again for strength to make a rated wall, steel is a giant headache
>>2443664Not much worse than reinforced concrete. >>2443877>A fire will cause the whole structure to flash rust, and they studs will probably fall apart with how thick the rust will be and how thin the steel is.It is kinda made out of same shit as cars are made of (well, older ones, because this is just cold-rolled that was galvanized). So shit would be fucked.But on the other hand, steel doesn't burn. >Biggest problem stopping me from using steel is windloads in florida, specifically hurricane ratings is a lot harder to get info on with steel, where you can just screw studs together over and over again for strength to make a rated wall, steel is a giant headacheThere are design manuals that tell you what kind of side load can shit take. But lets be honest, RC is probably the best material when it comes to hurricanes. Steel is the best when it comes to earthquakes.
