regular roofing asphalt paper under 3/4" wood floor?
I ordered my 3/4" Brazillian Redwood back in April, it finally came in yesterday. We are installing in a 2nd floor bedroom on 3/4" plywood over 2' span joists, perpendicular of course. The spec sheet says "laminated rosin paper or #15 builders felt (tarpaper) may be used to reduce movement and retard moisture, etc."
Just wondering if this is typical asphalt roofing paper? I happen to have a roll and a half of this from redoing the exterior wall. TIA.
