Hi. Is it worth laying “butchers paper” or other material such as thin foam to prevent squeaks between the hardwood and the subfloor? What is best to use?
Also, I am raising the floor, should I use a similar product between the original subfloor and the studs of the raised floor? Thanks for any info.
Why are you raising the floor? Are you installing solid wood on concrete? If so, do you want me to send you my article concerning wood floors on concrete?
And by the way butchers paper laid just under a wooden nail down floor is less than useless. No squeak prevention here. I have to know more about what you are planning before I can advise you.
