Insulation is important for containers because it helps them keep a consistent internal temperature and limit the damage caused by extreme highs and lows. This makes them a great option for use as offices, workshops, living spaces and even storage.
There are a few different types of insulation that can be used to insulate shipping containers. The one you choose will depend on your climate, design and budget. Some insulation materials are more environmentally friendly than others, but all options are effective at keeping heat inside and reducing your energy consumption.
Foam board insulation is a popular choice for container insulation because it’s easy to work with and can be glued directly onto the walls of the container. It also limits the echoing of sound and is water resistant. Other alternatives include blankets made of cotton, wool and other natural fibers. These can be mounted with a strong glue to the walls of the container or to bars that run horizontally on many of the container’s interior walls. They have a lower R-value than Styrofoam but are moisture-resistant and can be easily replaced when they wear out or become damaged.
Spray foam is another type of insulation that can be sprayed on to the walls of a shipping container. This type of insulation is more expensive than other options but it’s quick and easy to install. It can be made from a variety of materials including cementitious, phenolic, polyurethane and icynene, each with their own unique properties. Some of them have closed-cell structures which means air trapped in the cells acts as an insulator.
