PT is Pressure Treated, around here we had some code discrepancies about how to fasten upright studs for walls to cement floors and walls. Some guys use a first layer of pt 2x's some use a vapor underlayment then regular 2x's, I was just curios to how it works in other places...
Looks like they are doing a very good job, I always go on the calls where we are doing HVAC for basement finishings. We did one about 4 months ago with a basic heat cool hydro air system, the couple did such a nice job in their basement, contracted it out themselves, the bothroom they put down there was all natural stone, built into a corner of their basement with a custom glass door, they did a full bar with 4 taps, coffee machine, sink, soda machine and ice machine. No theater but a nice tv on the wall with a nice couch, I went back to fasten on the final registers and do the hvac finish, mount the t-stat, run everything check it all out and it looked fantastic, they did around 1100 sq feet of their 2200sq ft basement {single level ranch, full basement} and it cost them around $60K, but it looked first rate, very very nice work...
I am saving this thread, can't wait to see the progress, very exciting stuff...
