I have been researching for days now figuring out the inexpensive, yet effective way to finish a basement. The best information I've found so far has been from this website, and more specifically this thread: http://www.avsforum.com/t/1307424/how-to-affordably-warm-basement-floors/30
So although I am not currently planning a home theater in my basement (have a newbie one upstairs already) I would like to pick the brains of what seems to be the most helpful group of forumites I've seen in a while.
I have no current moisture issues (24-hour plastic test went stellar) and have never had a leak or puddle in the basement in 6 years. So far my plan is to finish the basement using 1" XPS foam on the walls and 1/2" XPS on the floors, all sealed and taped. Then for the floor I am thinking of putting down 2 staggered 1/4" OSB ply boards.
Here is where I'm lost. Ideally I would like laminate for the flooring option, but the wife says carpet for the kids since the rest of our house is hard floors. So, carpet it is. My question is this: Can I carpet on a floating plywood floor? Do I HAVE to Tapcon it, because I'd really rather not put holes into the concrete if I don't have to...Also it seems like it would hurt the integrity of the moisture barrier the XPS creates...
Then, since the walls aren't load-bearing, could I build the walls up from the subfloor base rather than using PT bottom plates at the concrete level?
I do have one other question that actually relates to audio in case I decide to do a home theater down there. In order to save on cost I am planning to paint the entire ceiling (pipes,wires and vents included) black. Would this wreck the sound quality of a basement home theater?
Any assistance would be terrific and greatly appreciated! Thank you!!
