Cold-Formed steel stud question

Cold-Formed steel stud question

Cold-Formed steel stud question

(OP)
An architect I work with asked me a question about the steel studs I am using on a project. He asked if they have ridges on the corners to provide a bit of a thermal break. I have not heard of any such studs and I was wondering if anyone else has.
Thanks

Steve:
Why not have the Arch. provide some tech. literature, ICC ES reports and availability info. on the product he is talking about and wants you to use? This puts the monkey back on his back where this stupidity belongs. Don’t use steel studs, that’ll solve part of the problem. You can hardly spec. something that only he is aware of. He could just glue 1/8" thick by 1.5" dia. hard rubber washers on the flanges of the studs wherever they will be installing attachments to the studs. If he wants to save some money on the washers and glue he can use .5" dia. washers. This requires a bit more placement precision, but he has CAD and BIM so that should be no problem. The Arch. should have that all worked out after they get done picking the tile color and the BIM file layer color for the washers. Pink is a really perty color for the washers.

The big thing in our area is insulated rainscreens on metal studs sheathed in Densglass.
I work with a fabricator to design the clips and purlins that go between the Densglass and the cladding.
Sounds like dhengr has dealt with TOO many Architects :>

RE: Cold-Formed steel stud question

I actually count a couple of Archs. as friends, when I’m not working with them. The correct answer to the Arch’s. question is; no, I haven’t ever heard of those studs. Why don’t you dig up some tech. info. and detail on them, also their availability, and share it with me. “Share,” is the new friendlier, PC word for... You do the hard work and then give me the results, I don’t want to be bothered doing the leg work on your wild ideas. The Arch just didn’t use the share word for lazy, when he asked you to research his problem. But then, he probably thinks he’s the boss since he’s paying you that trimmed down fee, so he has more money to spend picking the brick color and that kinda critical stuff. Next thing ya know he’ll want you to share the redesign (your 2nd design) when he changes all the column locations; for the same fee, of course. It sounds like ExcelE has the right idea if the Arch. wants to start to provide a real thermal break. We’re seeing a lot of that in the upper mid west too.

dhengr,
The problem is the Arch does not really know the product and was relating something the client wanted/mentioned. I did in fact tell him that I nave not heard of that type of stud before and that what I am calling out is per SSMA. Another Arch working on the job thought it might be the ViperStuds by Marino Ware, but they are for interior use not exterior. I just though I would ask, I am leaving it up to the Arch to note it on their plans.
Thanks

RE: Cold-Formed steel stud question

On that thermachannel, keep in mind it appears it is just a 3 5/8" stud with about 47 mil thickness (close to 18 gauge).
Appears ideal for an interior condition, but I would like to see at least a 6" stud at your exterior wall for deflection.

REtired,
Thanks for the info. I have looked at their website and downloaded their product catalog, and it looks like the do make them in 6" studs. However the catalog does not have load tables but it does have section properties. Again thanks for the info.

RE: Cold-Formed steel stud question

If using those for any type of diaphragm action, I would be dubious. The fasteners go through air before they get to the stud.
