ᐅ Distance between the substructure of solid wood flooring and the wall

Hello,

we want to install solid wood planks, most likely pine, on a wooden substructure.
How much gap should the substructure (KVH timber beams) have from the wall to ensure it is decoupled from the walls?

Best regards,
Jens

Maybe this helps… This is how it looked for us… so quite close to the wall.

Make it 1-2cm (about 0.5 to 1 inch), just enough to ensure no tension can occur at any time.
We basically laid the KVH beams directly on the floor with only insulation strips underneath; it sits perfectly. Wood fiber boards are placed in between.

Thank you for the photo and practical experience.

@ Arauki11 Do you have another photo of your construction? We also want to use wood fiber boards, and I am curious how the insulation strips are placed on the floor. They are for height adjustment, right?

I’ll take a look, I think it should be fine.
The floor should be relatively even, with any debris like plaster residues removed. I was a bit concerned myself and originally planned to screw it to the floor, like I did in my previous house.
In the end, though, the floorboards are connected to the entire surface of the room and the structural timber (KVH) like one large panel, so nothing is loose.
Actually, I just placed these screed insulation strips (which I had leftover here) under the KVH. You can also use them to secure it a bit.

Can you make sense of this? If not, please let me know.
We did it this way in all rooms except for the bathrooms.
The strip was also applied up along the side of the wall.
The distance was always to the finished fiberboard panels.
