I take it you are referring to traditional framed wall sheathed with foam & then they attached osb strips for nailing or to act as a supposed rain screed detail?
I don't think there is an official name & I am sure there might be a few regional terms but I would say crap sums it up quite nicely - one term I know of is burglars delight, who needs to go through the door or window?
This is a 2x4 with 2" rigid foam glued to it, and 1/2" OSB glued to that bringing it to the same dimensions as a 2x6. The wood faces out to nail the sheathing to and the foam and osb faces inward. I will get pictures of it tomorrow.
This is my first time working with the stuff and it sucks. The quality is worse than standard studs, the osb and foam gets crushed and broken, the foam falls off if you look at it wrong.
I can think of better ways to achieve whatever their goal is in using that. That just sounds like a pain in the butt. So when you fasten sheetrock to the studs, so do you have to use extra long screws to go through the OSB and foam and into the stud, or just screw to the OSB? Why not just build with ICF?
Not sure the proper name, that is what I am trying to figure out. It was there before I got on the job.
The stuff in the picture could be 1 /18, but ours isn't. If it was that thick it would protect the foam better and mean less damage to the foam when building. I will get pics up at 4 or so when I get home.
I'm sure it's a PITA with learning curve, but performance wise that is a great idea...... if you have ever seen a thermal imaging photo of a home in the winter you can see the skeleton of the studs from the heat transfer.
It isn't much different than working with standard lumber, besides the fact that the foam breaks off way too easily. I would say this definitely slows down production a bit, especially when everything is frozen together or to the deck. Personally, I wouldn't buy a house built with this stuff. I would prefer 2x6 construction with foam on the sheathing.
