Well, my bad. Looks like there is 5/8" OSB subflooring. But like floorguy says, 20" OC for 5/8"? That's not gonna cut it. You will definitely need to overlay 1/2" plywood before any hard surface flooring can be installed.
I called my builder today and they told me the joists are in fact 16" center to center. I guess the subfloor is just rated up to 20"...
I called Mirage, from whom I will be buying 3/4" solid maple and they suggested overlaying 3/8" plywood. This will bring the subfloor to a total of 1" think. Does this sound reasonable?
At Home Depot I have 3 options for 4x8 sheets of 3/8" plywood, which I know nothing about:
1) Spruce @ $13.25 each
2) "Fir - one good side" @ ~$24 each
3) "Plywood standard" @ ~$40 each
The guy there told me to use the cheapest (but also didn't understand why I was going to bother with the plywood at all). What do you recommend?
Thx for the help.
