Greetings everyone!
To give everyone an idea of my project and subfloor ideas here is what I have failed at so far:
I just opened my second floor with a set of stairs which gives me access to my 600 sq ft attic. The original 1x4 planks were still up there on top of 2x8 joists. The floor seemed level and since I have never tackled a new floor I figured I would buy some cheap OSB panels (1/4 inch to be exact) and go crazy, the finished product would be carpet and pad on top of the OSB.
I installed all the OSB boards and figured I would stop and wait for winter to pass before I start doing more. Well as I continue to check my attic I noticed the lovely cheap OSB boards sort of bowing or bubbling, and the floor is uneven, it seems the 1 by planks didnt like some of the screws. Well, now that I am frustrated at myself for taking the cheap route I have decided to rip up the 1/4 in OSB and the planks and start from joists up. I will be planing the joists to make them all level and my real question is sort of in two parts.
Part 1, the main space upstairs will have carpet, so from the joists I would assume to use some type of OSB or plywood, followed by a carpet pad and carpet.
What thickness and what type of boards would you guys suggest?
Part 2, there is a 12x10 space off to the side of the main room that I will be attempting and most likely failing at making a bathroom, full. It seems I have read more about this aspect than regular carpet aspects, I am thinking 1/2" plywood, with 1/4" cementboard and then my tile. I want to build a tiled shower as well, so cementboarding the entire room is no issue for me.
Also, the attic being upstairs and right below the roof, I will be putting insulation in both the walls and ceiling, right now its a bare room, but would one suggest greenboard instead of basic drywall? I will most likely be using the greenboard in the entire bathroom regardless since its a bathroom, but not sure if I want to spend the extra $$ on a basic room that will most likely see no moisture.
Thanks all in advance!
