Yeah, OSB blows. I have no idea how those engineered joists were approved; while they might be straighter than real boards they are definitely way more susceptible to water damage, rot from the water damage, and fire due to the thinness of the middle and the increased surface area of all those chips. But guess what? It's cheap because you can use whatever shit wood is available, so that's what gets used.
Incoming claims that it's stronger than and resists rot better than plywood.Real world experience says it's not true. Sorry nerds.
How are roofs installed on European timber framed/brick/stone houses? Is it basically the same as this, just have the primary material going up to the peak, have a beam bridging those sides and a plate on top of the walls to attach rafters to? Or do they use non wood roofs in some houses?
>>2866982Tell me why anyone would use anything other than tin for a roof? Please enlighten me
>>2866963load bearing structural members made from glue and sawdust is just tofu dreg for the western marketimagine your kids clogging the toilet and flooding the place and your floor caves in
>>2866987I am not talking about the actual roofing, just the structure.
>>2866990Oak hardwood or structural treated pine
>>2866987You can't walk on a tin roof.
>>2866995You walk where the screws are because there is a bearer underneath
>>2866995>>2866996Or joist I mean
>>2866982Old style is like this then small slats across then put shingles on that. Sometimes with a central beam as in pic. Also the top horizontal (we call it ‘pulling beam’) is sometimes lowered to make an attic, or put higher up to make the top floor taller. But also like European building styles are pretty different I think in Spain they do something completely different, they usually don’t have a lot of slanted roofs anyway. And Romania they just do concrete everywhere
>>2867009Are beams that size really being used for residential housing?
>>2866960You forgot one: Cheap.what else matters?nothing.Also, comes in exterior-grade adhesive, has more phenol resin in it. Although not enough.When you attach your tile to it, a slow leak causes it to swell and cracks the tiles.Makes good “ballast” material.
>>2867047>You forgot one: Cheap.>what else matters?I am not Jewish
>>2867015yes
>>2867251on top of that you put a membrane like tyvek as a back up in case a tile fails the bottom of the tyvek ends up in the gutter.then you nail vertical boards onto the rafters, there is a butyl tape between them so it seals the nail holes. then horizonal boards on these to create a ventilated air gap
>>2867254then clay or concrete roof tiles
>>2867258now you have a roof that lasts 100 years with minimal maintaince. No the tiles do not break from 2" hail cou can walk on them without breaking themif you have storm you fix every tile with a wire storm tie to the batten.if one does break or fly away you go up their with a ladder and slide a new tile in
>>2866963If you're that worried about potentially continuously flooding your house for whatever reason, just build a brick house and use reinforced concrete for floors.Wood rots too, you know.>>2866976It is stronger, that's just a fact.It doesn't resist rot better than plywood, but it's still more resistant to water because it doesn't delaminate like plywood does.>>2866994Using hardwood for rough framing is up there amongst the most retarded things I've ever read on this website. Might as well use nails made out of titanium
>>2866988wtf are you talking about
>>2867288They are making joists from OSB now
>>2867280>continuously flooding your house for whatever reason, just build a brick house and use reinforced concrete for floors. Wood rots too, you knowYou're not wrong, and it's one of the reasons I like the Florida-typical construction of block and slab as opposed to the framed houses I've owned before. But you're assuming that all water damage comes from flooding - most of it is small leaks around drains and fittings in addition to small roofing or siding failures. The type of thing you don't notice unless you're doing walkthrough inspections of your home on a regular basis plus every time it rains. Sure, real lumber and plywood will rot too, but you have a lot more leeway to catch it before it's catastrophic when compared to OSB. Also, there's no way those engineered joists are more fire resistant than actual lumber. Yes, your house is fucked in either case but I'd rather have the additional time to get out before floors start collapsing.>it doesn't delaminate like plywood does.Tell that to the pile of exterior-grade OSB sitting out front of the stalled construction in my neighborhood that I've been watching puff up and separate.
>>2867312Your floor will sag before it collapses, so you'll have time to get out. A leaking fitting will not make a floor collapse. You're being neurotic.As for OSB puffing up and separating, yes it does. But it takes more for it to do that than it does for plywood to start delaminating. Neither should be exposed to the elements anyways.For me using I-joists in my house was a no brainer because of how rigid they are and how long they can span unsupported, enabling me to have an open floor plan. Also makes routing electrical and plumbing a real breeze. I did not come across any real downsides to them tbqh
>>2867307That looks like SB. No Orientation.
>>2866995We walk on tin (galvanized we call them) roofs, every day>>2866995Standard construction in my area allows you to walk between the lath board. We also put our screws on the peaks, not the valley. Less rain intrusion in case of a gasket failure.
>>2867047>Also, comes in exterior-grade adhesive, has more phenol resin in it.That "exterior" grade shit, aint shit either.
>>2867397Galvanized roofs aren't nearly as slippery as a standing seam roof.
>>2867397galvo is steel after its been coated with zinc and other shit, is it just a regional dialect thing to call it galvanized? not trying to be an asshole, i wanna know what you mean
>>2867455No, it's actually galvanized steel that's usedTin isn't used around hereOnly idiots call it tin roofing
>>2867460i thought as much, thanks for clarifying
