did you know that containers can condensate?

As with any large purchase, most people will tend to do some research on what they need or want to buy. Typing “containers” and “condensation” into Google brings up a lot of different things; from why containers condensate to how to protect items being shipped overseas from moisture damage. The one thing that most of them do not tell us about is that a container will condensate whether it is being shipped from one country to another or just sitting in your back yard.

When anyone walks through the front door of the office looking for a storage container, one of the first questions I ask is “are you aware that containers condensate?”. If they are a frequent container owner, they do, but for those that are purchasing a container for the first time are not. Containers are a great way to store items. They are durable, provide a varying size of spaces, are portable and convenient. Depending on what you plan to store in the container, and how these items are stored, will effect whether or not you decide on purchasing a Condensation Stop Package along with your container.

Before we get into what we provide to stop condensation, let’s look more into how a container condensates. Container rain is more common that you may think. SeaBox Depot only sells cargo-worthy containers – this means that they are wind, water and light tight. Essentially, they are made to protect items from the elements while being shipped overseas. Unfortunately, one of the downfalls of owing a cargo-worthy shipping container, although they do not allow the elements or seawater inside the container, there isn’t a whole lot of air being cycled through. As with any self-contained unit, this will allow for the container to have its own miniature eco-system.

The outside air will depict the temperature in the container; warm days will allow for warmer temperatures inside the container, where as cool weather will make the inside of the container cold. When the inside of a container gets hot, it will allow for any moisture that is inside the container to collect in the air. Once the air cools, the moisture found in the air will become dew. We see this effect quite often throughout Alberta – dew on the grass in the morning or fog on a cold day. When the temperature cools, moisture will accumulate on the roof and walls of the container. Once these moisture droplets become heavy enough, they drip from the ceiling onto the stored items or run down the walls and potentially create puddles. To put this theory into perspective, think of a cold can of pop on a warm day. The outside of the can will develop moisture and run down the can – the theory is the same with a container.

If you’re thinking ‘well, I’m not storing any items with moisture in them’, think of this; moisture can come from varying and unlikely sources. It can come from something as simple as a cardboard box or the plywood of the container floor. I see containers all the time that are empty and have condensation accumulated on their roof.

As most of us already know, moisture in any enclosed area without a lot of air flow can lead to devastating effects. It can cause mold and mildew, ruining any items with a porous surface such as household items – couches, linens, etc. On pieces such as gas tanks or steel parts it can cause rust and corrosion – the list can go on.

Here, at SeaBox Depot, we have developed a way to prevent moisture accumulation in the container. We allow for more that just additional air flow – we provide a condensation barrier on the roof in the form of spray foam. Spray foam has a long list of potential benefits but we will get into that more in another blow.

Ultimately, SeaBox Depot wants any and all potential container owners to be aware of the risk of condensation inside their containers.
