My home is a ground-floor unit in a condominium. The floor is really quite cold and I'd like to do something about that. I saw in another question the suggestion to use Platon. Would I be able to put laminate on top of that? Or is there something else I should be using?
The floor is currently laminate, I'm not sure what's underneath but I suspect it's probably just the bare concrete, perhaps with a thin layer of foam, but I'm not really counting on it. Maybe laying down some thicker foam underneath would help?
Update:
Some more details. I live on the west coast of British Columbia, near Vancouver. I'd like to avoid installing anything that requires power to operate, so some sort of passive solution would be best. I could probably spend up to $10k on the project, but of course less is better. My unit is about 1000 sq ft.

If you are on slab, the planton (or DeltaFL) should be a good option.
As I commented in that answer, I re-did my basement a couple years ago and used DeltaFL, and it's been great. It really does feel like a regular above-grade floor, and isn't cold at all. It's reasonably cheap to install, my cost (for the membrane and plywood) worked out to about $0.83/sqft, so at that price it would cost you $830 (plus some tapcons, tape, etc). This only gets you to a subfloor, so then of course you need to add on the finished floors.
If you're not on slab, and there is an unheated crawlspace or basement below you, and your floor is a wood floor, the best option is to insulate from underneath (something presumably your landlord should be doing).
