Shipping Containers: Keeping Them Airtight and Secure

Are shipping containers airtight? Containers shipped across the ocean are sealed tightly so that whatever is inside the container will survive the trip in every kind of weather condition that is imaginable. Additionally, during ocean crossings, the seawater and salt warm moist air in shipping containers must be protected against corrosion. Container Sales Group will not disappoint you with our containers as we have already checked our containers properly.

It is widely known to those who have built or designed houses, as well as those who have re-roofed some or converted an attic area to a living space that proper ventilation is important to maintain a healthy, comfortable environment. This is also true for containers.

Rather than delving into the science of how an improperly vented envelope or container can cause roof leaks due to freeze thaw cycles during the winter months or how condensation on the inside will allow mold to grow, I will refrain from discussing the science here. People have reported seeing large raindrops drop from the roofs of storage  containers onto their contents because so much condensation is accumulating inside.

There are articles that suggest you glue insulation board to the inside of the roof as a solution to dripping condensation, but this is one of the worst things you could take. Between the steel and foam, condensation will continue to occur, but the foam will trap moisture, causing the roof to rust from the inside due to moisture trapped in there. Shipping Containers Airtight is the only way to go when moving your belongings!

Vented Air Space

A vented air space is required to add insulation to a roof. You will need to put some work into this and unless you are trying to keep the extreme heat in, this would not solve the problem any better than just adding vents without insulation.

Keeping your shipping container’s interior from mold and the contents dry is the same thing as keeping the roof of your home functioning properly. Vents can be fancy automatic ones or ones that have solar-powered window fans or ceiling fans, or simply simple ones. It is more important to focus on placement here than style. Creating an airflow through a container will not be able to remove the humidity with a single air vent.

You will need multiple vents. Although some people cut roof vents into their container roofs, this works well for them, I prefer to minimize future leak potential by placing the vents high on the side walls in order to minimize roof penetration.

Specifically, you should install four vents on each side wall, four feet from each corner, and another set of vents on each side wall toward the middle, at the very least. Although it would not be perfect, it would allow some air to flow and could reduce some condensation.Heat rises, so using convection is the best fix so that hot air can circulate through all four containers by installing vents on the side walls (and one on the middle of the 40’s) to create an airflow through the whole container.

It doesn’t matter what type of vent you choose, you just have to choose and position them so rain doesn’t enter the container. In addition to allowing moisture to escape, ensure you seal and flash your vents to prevent rodents and other small animals from taking residence in your container. This application is perfect for one of the many types of crawl space vents and foundation vents. They install flush, can be painted, and mount easily. Installing a properly vented container will result in immediate and long-lasting benefits.

Installation and Ventilation of Dryers

When a dryer is positioned, appliance recommended installation including the washer and dryer needs to be on a solid floor. A level couch should have four leveling legs and be reasonably level. The top panel should be checked for level with a carpenter’s level. The top of the dryer may need to be alternately pressed against diagonal corners to check for looseness of the legs. The floor may need to be reinforced with a half inch plywood platform under the dryer and bracing under the floor joists in order to prevent the floor from becoming spongy. Make adjustments to the leveling legs as necessary. The leveling legs should be adjusted with an adjustable wrench of 12 inches. 


The exhaust vent should be placed outside to allow excessive heat watch, lint, and moisture to be vented to the air. Wet clothing placed in the dryer will contain around two-thirds of its weight in water. It is necessary to release the water to the atmosphere after the dryer removes it. Upon properly venting the dryer exhaust, this moisture will be expelled outside through the ductwork in the house, and through vent louvers.

The excess moisture vapor will then condense in the laundry room, condensing on the walls, ceilings, and contents of the room when the dryer exhausts fans into the space. Upon recirculating the vapor back into the dryer, the efficiency of the dryer will be significantly diminished because the air already contains so much water. This is not the right thing to do.

Dryers should always be vented outside. Although the majority of electrical dryers can be used without outdoor vents, this isn’t recommended. Gas dryer exhaust should be directed to the outside in accordance with the American Gas Association rules. Don’t forget to check local codes on dryer ventilation.

Proper Voltage

The majority of major home appliances operate on 220-240 volt wiring. Plugs for these large appliances consist of two blades and a prong, and they are connected to a grounding wire. Plugging these appliances into a grounded outlet is required. Openings should be provided to accept both the blade and the grounding prong on the outlet. Additionally, an adapter plug can sometimes be used to ground the appliance. There will be a label on the appliance casing that tells you how much power it needs in watts, volts, and amps.
