what is the best way to insulate a beam-and-block ceiling over an unheated basement? The blocks are placed between wooden joists, and in some areas, steel beams are attached to the joists. The block height is about 15 cm (6 inches).
My ideas are:
I am particularly uncertain about the point regarding the membrane on the blocks. I do not want to apply a screed. The thermal insulation above the unheated basement should be realized mainly within the blocks since the ceiling height is limited.
Does anyone have tips on how to optimally insulate such a setup? Sound insulation is not that important because the basement is only used for storage and is not inhabited.
Best regards,
Frank

My ideas are:
- Install a membrane on the concrete slab (vapor-permeable or vapor barrier?)
- Level the blocks with a loose fill insulation on top of the membrane
- Fit OSB boards between the joists (saves valuable ceiling height)
- Possibly fill the spaces between the joists with insulation similar to what is used under screed (EPS)
- Apply the membrane continuously across the surface
- Lay impact sound insulation
- Install parquet flooring
