About

Insulating flooring is important to homes in all climates. In cooler areas, keeping heat from escaping through the floor helps keep the home warmer and saves energy costs. In hotter regions, keeping summer heat out of the house and reducing moisture helps keep things cool and reduces the risk of mold or other moisture-related problems.
