Intermediate flooring with low construction height in the basement.

[JSellberg]

If you're redoing the intermediate floor, is it okay to do it like this then?
The idea is that I will cut the nail battens, which will hold the insulation up, into small pieces that I place between the beams. This is to save ceiling height.

It's only 190 in the basement and tiles will also be laid, so every centimeter counts.
Under this, the plan is to install a regular ceiling.
Does this work?

Some form of wind barrier fabric is enough to keep the insulation in place before you install the roof panel.

Thank you for the response!
But if I take down the current ceiling, I will probably have to remove the insulation that is already there (probably sawdust or something similarly troublesome).

Can I then install new insulation from below in a good way? Otherwise, should I remove the insulation and leave it empty until the day I open it up from above?

Everything will be opened from above in the future when I plan to install underfloor heating on the entire middle floor, so I could completely remove the insulation now when I do the basement ceiling and wait to insulate until I install the underfloor heating on the middle floor. But maybe that's a bad solution?

However, it seems troublesome if I have to wait to fix up the basement until the day the underfloor heating goes in; I would prefer to finish it first so that everything happens in stages.

It is always much easier to insulate from above, but if the basement is less heated than the upper floor, it might be unwise to delay insulation. If the floor joists are laid with decent precision, it usually works well to push mineral wool up from below between the joists and have it stay in place. A compromise is to push in a thin (about 5 cm) board now and supplement from above later.
