APOC organic felts are designed with True-Breathe® Technology. This engineered technology keeps rain and water on the outside of your home while allowing water vapor from cooking, cleaning, bathing and other sources to escape home entrapment. Tru-Breathe Technology helps prevent premature damage and rotting of your roof deck materials which can lead to unsafe structures and the development of mold. Make sure you use Tru-Breathe Technology on your home or next project!
