Leveling on concrete floor

[Anna_Robban]

Hello!
I'm going to frame a wall out in the storage area. The base is a cast concrete slab. The house is from '68 and there is probably no insulation under the slab. Is it sufficient to frame directly on the concrete, or should I put a strip of regular roofing felt under the frame?

Thankful for any advice!

Yes, with a strip of roofing felt, you are very secure. Another alternative is steel studs.

Underlay felt should preferably be used, unless TS has roofing felt lying around and going to waste, it should be cheaper as well. If you absolutely must take a detour with roofing felt, make sure you have several layers to get some thickness.

Don't you think 1 layer of roofing felt is tight???
Detour???
Construction foil works too.

Paros S-list is preferable.
