Thickness of solid wood flooring at CC 800

[Tomas_P]

Hello,

I am considering installing solid wood flooring when renovating the upper floor of the cottage, but I have 800 between the beams. What thickness does the expertise recommend for the floor in that case?
Or should one lay chipboard and then the floor? But that feels a bit fake.

Thanks.

Floor chipboard on c/c 800 sounds like so-so you lay wood decking that is 28 mm c/c 600, so around 45 mm should work, one might think.
I haven't tried, just making an estimate based on the decking, the wood floor we removed in our first house was around 35 mm but I don't remember the c/c on the joists there, it was more than 600 though.

Can't you add another beam in between then?

I seem to remember that I had a 34 mm tongue and groove wooden floor. I also believe that there was up to 750 mm between some of the floor joists. It might work for you too, 34 mm.

Had between 800-900mm between the floor joists in the kitchen. Added spacers and had to cut the insulation, but there is a 22mm chipboard and 20mm tongue-and-groove wood floor depending on that we hadn't quite decided on the type of floor - but you avoid "squeaky floors".

The old kitchen floor was probably 38mm tongue-and-groove.

Hi,

Thanks. I'll do as you say and complement.
Anyone with good tips on how to attach these to log outer walls? Is a joist hanger stable enough?

Best regards

If the sill (log outer wall) is healthy, sure!
