Basement floor Dleta fl and osb vs xps and osb
I have read countless posts on basement floor. I was meaning towards 1 inch xps glued to floor with osb (advantech or similar) over it for a warmer floor. My other option is delta fl (that dimpled plastic) with osb over it. The dimpeled plastic would allow more airflow but the xps would be warmer. Which is preceded method? Also since the xps is less than 2 inches would I need a vapor barrier.
Thanks

There is no moisture coming up. The builder put crushed stone and poly sheets under the concrete floor.
If I used the xps and osb would it crush under the weight of a pounding treadmill or a pool table? Also would a vapor barrier be needed?
If I used the delta and osb, can I just glue the osb joints and leave it floating? I believe that's what the delta directions say. If you glue the joints then how does the 1/8 expansion gap work?

Basement subfloor insulation
Please let me know of this will work. I plan on doing 1 inch xps GLUED TO CONCRETE FLOOR taped seams. On top of this 3/4 osb GLUED TO THE XPS. carpet on top. Rather not use tapcons if I do not have too. Do I need to put plastic (vb) between the xps and concrete? Or between the osb and xps? Or no plastic? Thanks.

If we are traveling down this road, I will combine the threads, since they repeat themselves. http://www.doityourself.com/forum/fr...s-xps-osb.html

I did a test. Taped plastic to the floor and waited a couple days. Both sides of the plastic were dry...no moisture is coming up. (there is also plastic under the basement slab). Dehumidifier is also set to come on at a certain level.
I would like to try to do the floor floating if possible, but do not want the sheets to curl. I don't believe osb will curl as easy as ply. I rather not use tapcons in case I need to year.out of floods. Removing all the tapcons would be a nightmare.
Why should I not glue? Maybe not glue the xps to the concrete but what about to the osb? (the osb is advantech)
Or should I skip the xps and just use delta followed by tg advantech floating in top?
