Why are my floors freezing cold? It feels like I’m stepping on ice!?
sounds like a combination of air getting in under the house and lack of insulation.
Usually a lack of insulation under the floor or a draft getting into the home somehow. Is the bedroom on the main floor? Do you have a basement?
what's underneath? basements and crawlspaces get cold in weather like this, too. so does a slab floor.
Turn the heater two more degrees.
