In this basement we installed our Everlast Wall system to cover up those concrete basement walls and they are NOT like drywall. Drywall with fiberglass insulation supports mold growth, will damage from moisture, and will lose insulation value when wet.. We also added our ThermalDry flooring and a drop ceiling to finish off the new look. The end result is a much more inviting living space, ready to become a new play room or another livingroom, the possiblities are now endless.
