Post frame building surrounded by dirt and grass.

Ventilation is a critical consideration in any building construction project. Without sufficient air movement, buildings can accumulate moisture through condensation, causing mildew and mold. Left untreated this leads to wood deterioration, discoloration, and possible oxidation of machinery and other contents. Learn about ventilation for post frame buildings.

Ventilation in a building refers to the intentional exchange of moist indoor air for fresher, dryer outside air. Furthermore, without air movement, the interior atmosphere warms and increases the potential for holding moisture.

Eliminate Excess Moisture Buildup with Effective Building Design

With the help of a proven post frame building design expert, building owners can avoid unnecessary hassle and expenses that arise from ignoring the need for proper ventilation.

Engineering a system to support good air quality should be the primary criteria for any design. After all, good ventilation ensures the longevity of your post frame building.

Design Feature Considerations to Eliminate Condensation in Post Frame Buildings

Ridge Vents

Venting the top ridge of a post frame building allows rising warm, moist air inside to escape the building.

Eave Vents

Eaves and overhangs should include vents that draw cool outside air into the building. This can keep the building cooler while also creating airflow to reduce the heat and moisture levels inside.


A cupola or two atop your post frame building can offer architectural value and pleasing aesthetics. However, these roof structures also provide an escape route for hot, moist air. Cupolas come in many styles and can enhance the appeal of your post frame building while improving ventilation.

Gable Vents

Gable vents are typically found near the top of the roof. These provide ventilation for attics and upper levels of buildings. Moreover, they are usually placed beneath the top peaks at each end to allow cool air to enter and hot air to escape.

Doors and Windows

Doors and windows naturally offer other functions in any post frame building, but ample use of these also keeps air flowing throughout.

The essential element here is the strategic placement of the openings to allow for optimal airflow. For example, since prevailing winds tend to flow from west to east, orienting the building plus its windows and doors to take advantage of air currents is an efficient strategy. This can also help minimize your energy bills during the summer.

Exhaust Fans

Mechanical assistance is also necessary when leaving doors and windows open is not practical. An exhaust fan near vents will help remove excess moisture and odor within a post frame building. Adding ceiling fans, attic fans, and other air movers will also help keep air moving.

Other Considerations

Proper insulation is vital for minimizing energy loss and helping to maintain temperatures while promoting adequate airflow. Whether foam or batting, the insulation material must be resistant to moisture accumulation and mold or mildew development.
