Pole Barn Attic Ventilation

The international building codes require any dead attic space to be ventilated.

Pole barn attic ventilation.

Since lower temperature air cannot hold as much moisture as warmer air the excess humidity turns into water droplets. Don t skip features that can increase airflow. Warm air has the ability to hold more moisture than cold air. Place them in ways that allow air to enter and exit in a clear path to maximize the movement of air.

Mike the pole barn guru responds. To understand how proper ventilation works here s the anatomy of a basic passive pole barn ventilation system. The primary purpose of pole barn ventilation is to prevent condensation moisture build up. Additional doors and windows will both help increase the general flow of air through your pole barn.

Out with the moist stale air. Since you cannot increase the amount of venting in your soffits as you have none you ll need help from power vent fans. Attic vent fans can be hard wired and equipped with a thermostat and or humidity sensor so they automatically cut on at a preset moisture level or temperature. Lack of proper pole building ventilation becomes even a greater issue when an enclosed attic space is present.

In the case of a lined building with a ceiling air is rising in the building s attic. When this warmer air contacts cold surfaces in your pole barn condensation forms since the air loses its ability to retain as much moisture. Condensation occurs when warm moisture laden air contacts a cooler surface such as the underside of your roof steel. A literal example of this is that 45 air can hold 1 3 the water vapor that 75 air can.
