Hi,
I'm remodeling my house and have a flooring load question. The floor joists are just under 3" wide, true 8" tall, and span varying lengths depending on location. The spacing varies between 19" - 20" on center. Maximum span is in living room where they span 14', in the dining they span 11', and kitchen is varying depending on location, but nothing more than 14'. I cannot verify the species of wood. A few spots have cut out joists areas that have been headered out (prior to me owning the home). We ripped out the carpeting and linoleum that was covering the hardwood flooring beneath. The hardwood is 3" wide planks and is just over 3/4" thick; the hardwood is nailed directly the floor joists (house was built in 1920 time frame). The hardwood is in rough shape and has cut outs and patches in areas so refinishing is not happening. I plan to tighten up the hardwood flooring with deck screws to eliminate noise and stiffen up some areas, and then apply a 1/4" underlayment overtop stapled down with a crown stapler as specified to smooth out any slight imperfections that do exist in the subfloor, which there are some. I've priced out some vinyl plank flooring options to put over the 1/4" underlayment, some with pre-attached foam backs, some need foam underlayment added. The flooring I would like to go with is 2.89 lbs/sqft. Adding this weight to the original 3/4" hardwood and the 1/4" underlayment, I'm coming up with just about 6.75 lb/sqft in dead load. I looked at the various charts available online to determine load rating but this is beyond me. Should my current construction support this load or is it too much? I can easily go with a lighter flooring option but I prefer the one I chose. Any input would be greatly appreciated. Pictures for reference.
