Choice of flooring

[isoler]

We are going to lay new flooring on the 2nd floor (1.5-story).
There is about 1 meter between the joists.

What is usually laid? chipboard, gypsum board, raw planks...
I suspect the distance between the joists is too large to only use chipboard.

Hello
I just had the same issue, I guess you have about 15-20 cm beams as joists. Since my floor on the upper level needed proper alignment, I attached 6" joists on either side of the beam, making the c/c measurement about 700. Then I nogged between each longitudinal joint between the floorboards (22 mm). It seems stable and good. Additionally, I will place spaced panels on top to install underfloor heating, the thresholds can handle this.
