Why Concrete Floors Rock

Concrete is good for indoor air quality because it inhibits mold, mildew, and odors, contains no potentially harmful VOCs, and can be finished with zero-VOC sealers. Concrete's absorption of warm and cool air minimizes the need for heating and cooling. And concrete can be recycled and the surface cuts down on the need to discard waste, such as
