Basements should be insulated on their perimeters they should not be insulated between floors.
Should basement floors be insulated. If your basement floods at all or has any water leaks experts say to address that before considering any insulation solutions. When insulation is installed it is most commonly found between the floor joists to prevent the crawl space air from entering through the floors above. Whether your basement is finished or not proper insulation is important for temperature control and the prevention of moisture. That s because any insulation you might install on say the walls would potentially get ruined with excessive moisture.
Even if they are insulated the insulation tends to sag droop and stop working. Basements require special subflooring that will not get moldy or deteriorate when exposed to moisture. In most cases a basement with insulation installed on its exterior walls should be considered a conditioned space. Insulating concrete floors if you live in a cold climate then you re no stranger to cold concrete floors in the winter.
Ceiling insulation helps stop heat from leaking into the basement from the floors above which means it makes the basement colder significantly so. If you are planning to finish the basement space you should also consider adding a layer of foam insulation below the slab. Foam and water do not mix. Foam insulation for instance is a common material for basement walls.
If you re planning on finishing a basement or portion of your home that has a concrete floor then it may be a good idea to insulate it before installing basement flooring. A properly installed subfloor will create a flat insulated substrate for the finished floor of your choice ensuring more warmth underfoot. The insulation may not save much money in energy bills due to moderate earth temperatures at that depth but it will warm the floor surface enough to reduce condensation. If you do use your basement as a living space a home theater a playroom or a guest bedroom for example the answer is no.
