Re: Insulation under carpet squares
The rigid foam laid on the concrete is a very effective system of providing a nice warm and comfortable floor in a basement.

The carpet would be too soft to lay right over the rigid foam so, anything like the legs of a couch for example , would sink into the foam.
If you wanted to use the rigid foam you would need to place plywood or perhaps OSB overtop then lay the carpet.
Hopefully this helps.
