Types of Ecologically Friendly Concrete Floors

Concrete is a great conductor of heat, so it gets hot, and cold, very fast when exposed to different levels of thermal energy. Because of this, concrete is generally cold to the touch of skin, because the heat flees from it so rapidly. This can be a great benefit in the summer, by making your home naturally feel cooler.
