I am considering a floor solution with attic panels:

Room: Ground floor, basement, previously storage room, 70 m² in size.

Current floor construction: Original terrazzo floor, on top of that wooden pallets, on top of those screwed 18 mm thick panels, 250 x 150 cm large, probably something like multiplex panels (film-faced plywood? -- in any case built from many layers, must have been very expensive ...).

Now the whole thing is being converted into living space. Due to the hollow space under the panels, the floor in this form is clearly unusable; it thunders loudly with every step.

I am looking for the simplest, most cost-effective, and doable-by-myself solution, initially thought about filling with loose insulation, but now think that acoustically the following would be better:

I want to keep the actually fantastic panels. Instead of pallets underneath: foil, Styrodur, then some cheap panel material (which one?), and then screw the panels onto this.

Could I also use the standard attic panels (110+10 mm, 100 x 60 cm)? That would be quicker to install, possibly cheaper, the existing panels would probably be safe enough to screw onto (right?) and due to their stiffness would certainly increase the load-bearing capacity of the floor to a normal living area level. Or?

I derive some confidence that my construction would be possible from the description of a manufacturer of attic panels:

"By laying an additional gypsum fiberboard, the load-bearing capacity of the attic panels increases to living space level, and that with an additional installation height of only 10 mm. On this floor construction, all common floor coverings, whether carpet, tiles or laminate, can then be applied."

According to the manufacturer, attic panels with an additional 10 mm gypsum fiberboard allow a surface load of 2 kN/m² and a point load (on a diameter of 50 mm) of 2 kN. That practically corresponds to the load-bearing capacity achieved with dry screed elements for application area 1 = living areas up to medical practices.

In my case, instead of the gypsum fiberboard, the already existing multiplex panel would go on, which is certainly much more load-bearing than a gypsum fiberboard (and also twice as thick).

Inexperienced as I am, I welcome any comments, tips, and advice. Thanks in advance!

I cannot say much about your construction, only that unlike thermal insulation, heavy material is more suitable for soundproofing.



The question is only, how much soundproofing do you need?

Which heavy material would you recommend?
