ready for subfloor, 3 quick questions
I'm getting ready to put in the subfloor and I have 3 questions.
1. is the insulation usually put in before, during, or after the subfloor? All of my wiring comes down through the attic, so the only floor work to do later is the pipes (it's the kitchen). So, it wouldn't make much difference, just soliciting opinions, which is more convenient?
2. The subfloor will measure exactly 12 feet 3/4 inch along the joists. If I'm using 4x8 plywoood, I'm going to have 3/4" (minus spacing) left over at the end. What's the solution? It seems like there will have to be four rows of wood, so maybe I should cut the sheets down to 3 and 1/2 by 8 and have the last row be 18 and 3/4, or sth like that? or, since the last 3/4 inch is actually rim joist, maybe I should just buy one smaller piece of plywood and cut it into 3/4 strips and fill it in along the edge?
3. I double blocked the framing, 12 foot 2x10s with pieces of 14.5" 2x10, putting one at the 4' mark and one at the 8' mark (staggered 1.5" so I could nail them). There was a bit of squeaking walking across the boards after I finished, and then I put one 3" deck screw in each end of each blocking piece (which already had 3 16d nails evenly spaced). I still have a couple of spots that creak. Should I fix these (and how?) before putting down the subfloor, or should I count on the adhesive and the screws in the subfloor to take care of it?
