Whether you’re building a home or office in a shipping container, you’ll want to ensure that it’s well insulated. Insulation prevents thermal energy from transferring in or out of the space, keeping it warm or cool depending on the climate.
There are several options for insulating containers. Some are more expensive than others, but each offers its own advantages and disadvantages. Some of the most common are Styrofoam, cotton insulation, and spray foam.
Styrofoam is a good choice because it’s inexpensive and easy to install. It comes in panels that are ready to apply, and it can be glued directly to the walls of a container. This insulation also limits the echoing of sounds in the space. Its drawback is that it has a low R-value and can easily absorb moisture.
Other types of insulation include fiberglass and mineral wool. These are more expensive but offer higher R-values. They may also be more difficult to install because they require framing. They can be used in conjunction with other materials to create a better insulating system.
Closed-cell spray foam offers the highest R-value and resistance to moisture, but it’s more expensive than other types of insulation. It is available in many different formulations, including cementitious, phenolic, and polyurethane. It is often used to seal gaps and seams in containers.
You’ll also want to add a vapour barrier. This reduces condensation and helps to prevent moisture from damaging the steel of your container. container insulation
