My house was built in ’47. It has very squeaky oak floors throughout, except wet areas. The sub floor is 1×8 lapped fir, then the weird part is that I have furring strips (1×2 sleepers) on 16″ centers running directly above/parallel to the joists. the finish oak floor is nailed to the sleepers. (each layer is set perpendicular to the previous)
Does anyone have any idea why a floor would be constructed in this way? there may as well not be any sub floor – as the load essentially bypasses it and goes from sleeper to joist – no support in-between.
Finally, to reduce movement of finish floor as you step between sleeper supports (especially on end joints of finish floor that fall between) would anyone recommend injecting a low density foam or something to transfer load to the sub floor?
Any advice welcome!
Thank you,
