Post Frame Barn Ventilation – A Quick Review
It’s that time of year again when the humidity is high and it’s hard for you to escape the sweltering heat. We’ve posted some blog posts in the past about post frame barn ventilation and climate control in commercial buildings but thought doing a quick post to mention some helpful tips would be a good refresher!
When it comes to planning your new post frame barn, storage or ag building with a top post frame builder, be sure to consider the weather and its affects on your structure. As we’ve said before, it’s a good idea to think about ventilation, especially if you’re housing animals or temperature-sensitive material.
Why is Post Frame Barn Ventilation So Important?
Well let’s start with saying that its not just hot air that affects your post frame building, yet it is the most bothersome, so let’s focus on that. When heat enters a structure, there is no way for the air to escape without ventilation. The structure can hold the heat for many hours even if the temperature outside drops. If your structure won’t have a ventilation system or better yet, air conditioning, then here are a few options you could consider during the planning process to aid in ventilation:
Overhangs with Vented Soffits
Most people think of overhangs as a ‘curb-appeal option’ for their building, and that soffit is used just to cover the exposed roofing trusses; however, when overhangs are selected and a vented soffit is installed, this combination greatly aids in ventilation. This is how air intake happens to provide regular air circulation to your building.
Also known as a post frame barn vented ridge cap, a ridge vent is installed end-to-end at the peak of a roof. A gap is left at the top of the roof and either a metal or shingle-over vent is installed. This is how air is exhausted. Many times, the post frame barn ridge vent isn’t noticeable since it is normally low profile.
When using a gable vent, an opening is cut into the gable side of the building and a slotted vent is secured. Most vents include a fine screen that prevents insects and animals from entering.
We recommend combining overhangs with vented soffits and the ridge vent together to ensure a proper airflow. For large buildings, investing in industrial fans to aid in air movement could be a good idea. See the diagram provided to give you a visual explanation of the intake and exhaustion of air.
