Understanding and Selecting Fresh Air Ventilation Systems


This class illustrates why well-insulated, tighter, properly ventilated homes can actually perform better, last longer and are healthier to live in than the typically insulated, 'accidentally ventilated' home.  Tighter, more energy efficient homes require fresh air and systems have to be installed so they do not create pressure imbalances that cause back drafting indoor air quality (IAQ) and moisture problems.
