Insulating an existing floor over a concrete slab
I need to insulate an existing floor above a concrete slab that used to be the garage floor. The crawl space between the current floor and the concrete is insufficient to crawl into and place traditional rolled insulation. I need suggestions on how to insulate this floor without having to tear up/replace the existing flooring. Can I blow that loose insulation under there or can I lay anything down on the concrete that will help? This converted garage/room is several degrees colder than the rest of the house? Thanks for any suggestions.
