ᐅ Concrete floor, followed by insulation, then OSB boards

Hello

We have bought an old house. The foundation slab is already new. We are now sealing it with V60.

Above that, we plan to lay 6 cm (2.4 inches) rigid foam insulation boards and then OSB boards, with laminate flooring on top.

Is this feasible, or am I missing something?

Thanks for your many replies

Hello!

Walking is possible – it’s quick and inexpensive.

Screed would take longer.

A loose fill would be better for leveling unevenness.

Gypsum fiber boards offer slightly better sound insulation.

I would prefer a plank floor if the height allows – it is also a bit more challenging.

Laminate, however, is a matter of personal taste...
