Shipping containers are generally designed to be airtight because they traverse large expanses of water over long periods of time. That makes perfect sense, right? Of course! But what many of us don’t know is that they also require proper ventilation to increase airflow; and the more airtight the container is, the more airflow is required.
Why add a vent to something that’s meant to be airtight? Well, increased airflow helps reduce heat, deadly exhaust fumes and odours, while preventing rust, moisture build-up and mould. All this ultimately protects your container and its contents from potentially serious damage.
There are a few ways to get that valuable airflow into your container and they will differ depending on the intended use. The cheapest, fastest and most common way to add adequate ventilation is to fit it with a slotted or louvered vent.
What’s more, installing shipping container vents in pairs, on opposite sides, is the best option: one vent on the top left panel and the other on the top right panel on opposite corners. This will allow for optimal airflow. But for maximum ventilation, we always recommend to install a whirly bird on your container’s roof.
