What to install 1' thick or less to warm up concrete floor?
Hello. Our unfinished daylight basement has a very cold concrete slab floor, and we want to finish rooms that will be comfortable in winter. It needs to be hard flooring, no carpet, as it's the throughway from the lower garden and shop.
It's an existing daylight basement, reliably "dry," i.e., never any visible dampness, but we are in a moist temperate climate. Whatever we lay can raise the floor as much, perhaps, as an inch, but that's about it without changing sills and doors on 2 entries, cutting down 5 interior doors, and--most significantly--making the last step down the stairs dysfunctionally different.
Our budget is pretty tight, not "basement" but far from luxury.
I've preliminarily been looking at floating engineered wood and laminate, but would prefer a non-wood look so it won't conflict with our old pine steps. Someone said vinyl won't do...?
Any recommendations with thought to insulation against cold will be greatly appreciated. Thanks.
