Sparse paneling on old parquet - leveling.

[jeppeknaster]

The floor is raised on concrete and has chip insulation. On the joists lies a 25 mm parquet floor. In some places, the floor is severely sloping (up to 4 cm over 3.5m...) without any bounce anywhere. Now I will lay spaced paneling, floor heating pipes, and new parquet. The question is how to handle the level differences?

I see three options:

1. The (too) expensive option: 150 m2 with minor unevenness costs a lot. Not really an option.
2. The heavy option: To tear out all the old flooring, level the joists, and lay the spaced paneling on these.
3. The slightly easier option: To level the spaced paneling on top of the existing parquet using masonite/batten screwed into the parquet.

Anyone with other options or opinions? Do you think the easier option will work?

In my opinion, option 3!

Puh...

Just over a year later, I have (almost) decided how to do it I had a carpenter here and he mentioned that it would be really complicated to level everything with masonite. He suggested I should glue and screw drywall onto the wooden floor in the deepest dips and then use self-leveling compound to make it even.

After that, I thought about either laying sparse paneling and metal or going with the "drywall method" (but with 16 or 17mm tubing).
