Nails – steel studs thermal bridging
Maxxxx001
| Posted in General Questions on
Hi Friends,
Search yield some results but nothing specific.
finishing basement with steel studs. ( continuous EPS around ) and then the frame.
only issue is bottom track for studs – I’m thinking of 2” EPS or XPS between track and slab not sure if that will be secure enough. And is 2” enough for thermal purposes
question is if nails will be a problem, they will be the thermal bridge ? To the frame
I was going to go with PT 2×3 and nail track to that, but 2×3 are not available in my area.
thank you

What is your subfloor? I would expect a subfloor over the foam, and the bottom plate above that. Ergo, your bottom plate would be tagged to the subfloor, not the slab.
Either way, I don't really see a few fasteners as being a crazy thermal bridge worth thinking about (when we're talking about a relatively temperate slab).

If this is something that needed to be done (not saying it is), just buy 2x4 and rip to 2x3...

Or rip a 2x6 in half.
Your late night brain works better than mine. ;-)
Thank you both, I would like to avoid ripping and sealing PT.
But good question about subfloor I was going to attach it directly to basement floor. ( concrete slab )
I will have the dimpled plastic membrane by Delta, should I lay that out before doing track
Or membrane like DMX 1-Step Floor Underlayment - R value of 4 ?
Thank you
