Power Ventilation in Your Attic-Why It’s Needed

  Sometimes in attics, regardless of the amount of ventilation and insulation, roof power venting is required. This forces the airflow from the soffits, out through the power vent. It is important to install a power vent with both a humistat (regulates the moisture levels) and a thermostat, which is set at 110˚F). Mold growth occurs in attics, in most cases, during the winter months. Warm air migrates from the house to the attic where it mixes with the cold air. This forms condensation on a variety of materials, including the plywood and supports. A humistatically controlled power vent will turn on automatically when moisture levels exceed 45% to remove the excess moisture. This is why we recommend a power vent in certain circumstances, such as multiple roof angles that can reduce natural airflow.
