I have a 1986 townhouse, 960 sq ft, with a 16' floor span, 2' struss system 24" OC. Currently I have laminate wood flooring on the first floor. There is some spring in the floor. From underneath, I cannot see that any of the subfoor is disconnected from the trusses, and I checked because I was told this could be a problem. Here's the question...:
Would I be better off installing hardi-backer board, approximately 675 sq ft, and placing a wood laminate, engineered wood, or solid hardwood on top? or trying to sister the trusses (every other??) or box them in???
If I were to leave the trusses as is and install the hardibacker, should the cement board be glued and screwed? If I am to control from below, should I use plywood or 2x8 to box in the trusses? I want little to no bounce, given the stats above.
I'd like to spend $5-$7 a square foot to replace the current flooring which would include a 48 sq ft kitchen, 40 sq ft bathroom and small laundry area (24 sq ft) which could (should?) be tile. ANY suggestions, comments, tips are appreciated. Please see the property sketch attached.
Thanks in advance!!!
