Insulation under laminated wood floor
I have a friend that has an existing laminated wood floor in den area that used to be a breezeway. The floor was just floated on the concrete slab with only a polyethylene vapor barrier. My friend likes to walk around in socks so the floor is really cold in the winter. I want to replace the floor and insulate under it. I have about 1″ to work with without raising doors and a slider. I was wondering if the standard 6mm foam underlayment is going to help at all. Or would I be better off using aluminum-backed 1/2″ or 5/8″ foam board followed by the underlayment. I have used this foam board to insulate finished basements and it seems to work great. It seem stiff enough to handle the weight.

Aluminum BACKED, but just some foil on it.
Foam has good conpressive strength, when spread out. But not in a small area.
I suspect that the edged of the laminate will flex enough to put force in consentrated areas and endup crushing the foam.
If you put a layer of plywood over it then it would work.
