The ThermalDry® Basement Wall System stops water vapor, drains wall leaks, and does something the other two systems cannot do - it reflects up to 97% of the indoor heat back into the basement. This saves energy and money because your heat is not absorbed and lost into the perpetually cold basement. This makes the ThermalDry® Wall System the preferred option for your basement walls if you are going to finish your basement in the future. When finishing your basement, leave a 1/2" space in front of the ThermalDry® for maximum benefit. Also - ask about our ThermalDry® Floor Tile system to lay under your carpeting.
