humidity control in containers

Why humidity higer inside than outside?

As air warms it can have more moisture. ... When it rains the amount of moisture in the air increases. The weather inside the home can be much different than that outside when it comes to relative humidity. This is because temperatures in the home can be much different than the temperature outside.

Ways to further reduce the temperature and humidity within the shipping container include:

• Place your shipping container in the shade, but not under trees.

• Build a roof over the container to reflect the light.

• Insulate the internal walls with traditional insulation or spray foam.

• Install cross ventilating windows.

• Install extractor fans to purge hot air.

• Arrange items for better air flow inside the container, such as stacking them off the floor on shelves or clean pallets, and avoid cramming the items tightly together.

• Mount a container on ConFoot legs for elevation that inhibits soil reactions and easier moving. 

• Regularly monitor humidity with a moisture meter or, better yet, a temp gun (for ceiling temperature measurement). 

• Set the container on gravel or 6-inch pressure-treated blocks for better air circulation.

• Park on high ground to avoid flooding and standing water.

• Keep the roof clear of leaves and moss since they trap moisture.

• Separate containers by 6 feet for better air flow.

• Avoid trees since windy locations allow storage containers to dry out.

• Add a roof-mounted, peaked tarp with a 2-foot overhang that avoids roof contact, to slow quick temperature changes. 

• Keep air vents unblocked.

• Avoid storing anything inside with a high moisture content.
