I'm building a floating floor to help with soundproofing a practice room. Using 2x4's as joists, and bought 3/4" thick 4' x 8' T&G plywood for subfloor, then Mass Loaded Vinyl mat, then 3/4" thick 4' x 8' MDF. The space is a perfect 8' x 8', so I thought it would be an easy build, but the T&G plywood is actually 48" from the tip of the tounge, so actually 47 1/2" wide, and the MDF is 49" x 97", one inch wider each way.
Why are these dimensions different, (like the 2x4 actually being 1.5 x 3.5) and how are they used in construction? Am I going to have to shave off an inch along the enitre width and length of the MDF?
