Pole Barn Attic Ventilation

Additional doors and windows will both help increase the general flow of air through your pole barn.

Pole barn attic ventilation.

Mike the pole barn guru responds. Warm air has the ability to hold more moisture than cold air. Condensation occurs when warm moisture laden air contacts a cooler surface such as the underside of your roof steel. In the case of a lined building with a ceiling air is rising in the building s attic.

A literal example of this is that 45 air can hold 1 3 the water vapor that 75 air can. When this warmer air contacts cold surfaces in your pole barn condensation forms since the air loses its ability to retain as much moisture. The process starts with warm moist air rising inside your pole barn. Since lower temperature air cannot hold as much moisture as warmer air the excess humidity turns into water droplets.

Place them in ways that allow air to enter and exit in a clear path to maximize the movement of air. Pole barn insulation is a core part of temperature control and ventilation. The international building codes require any dead attic space to be ventilated. 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.

The primary purpose of pole barn ventilation is to prevent condensation moisture build up. Lack of proper pole building ventilation becomes even a greater issue when an enclosed attic space is present. Since you cannot increase the amount of venting in your soffits as you have none you ll need help from power vent fans. Ridge vent without soffit vent one of the most overlooked areas of pole building construction is proper ventilation.
