What are my attic exhaust options for a house that is wider than 75 feet?
Here are your attic exhaust vent options for homes wider than 75 feet eave-to-eave regardless of roof pitch.
A house that is wider than 75 feet (that's eave to eave in a horizontal line regardless or roof pitch) will not be suitable for ridge vent because it will not provide the needed airflow for the overall volume of attic space. Multiple wind turbines or box vents (also called roof louvers) would be an option. The needed quantity of these vents would depend on the airflow capacity of each and the attic's square footage. It would be best to keep the vents on the same side of the roof in a single row. Another option would be roof-mount power fans evenly spaced apart.
