Shipping container homes and offices are edgy and eco-friendly, so it’s important to keep them comfortable year-round. Choosing the best insulation options for shipping containers can be overwhelming, but worry not! We’ve got you covered!
We’ll dive into four ideal insulation methods for shipping containers. Say goodbye to thermal bridging, condensation, and temperature fluctuations!
Reflective insulation, also known as radiant barrier insulation, bounces heat waves off its surfaces and prevents them from penetrating the shipping container. This type of insulation is typically made of aluminum foil adhered to an insulating material and functions best when facing an open space. Reflective insulation is lightweight, flexible, and effective in reducing radiant heat transfer. This insulation will be your first line of defense against sweltering heat!
Spray Foam Insulation
Spray foam insulation is popular among homeowners and developers for its excellent thermal performance from isocyanate and polyol resin. Professional spray foam insulation contractors can apply the material to the walls of a shipping container, and it will expand to fill the divets on the walls. One of the benefits of using shipping containers as building materialsis that the walls have a natural shape that makes it easy to apply the foam insulation. The spray foam envelops every gap, crack, and opening, eliminating air leakage and minimizing the thermal bridging effect.
This option has a few downsides. Firstly, spray foam insulation is more expensive than other types of insulation. Secondly, you must hire professionals to apply spray foam insulation. Still, the energy savings and minimal maintenance make it one of the best insulation options for shipping containers.
Rigid Foam Insulation
Rigid foam insulation uses panels made from expanded or extruded polystyrene that are cut to fit the container walls. These panels offer excellent insulation properties and are lightweight, making them easier to install than other insulation materials. They’re also mold and moisture-resistant, which is great for combating condensation in cold climates. These panels look nice on the inside or outside of structures, so using rigid foam is a good way to make your backyard more visually appealing if you plan on installing a shipping container storage unit on your property.
When using rigid foam panels, ensure they have a high R-value (the measure of thermal resistance) for maximum thermal performance. Installation is DIY-friendly, although it’s best to consult a professional when handling insulation work.
Earthwool insulation, also known as mineral wool or rock wool insulation, contains inorganic fibers manufactured from rocks. This type of insulation provides excellent thermal insulation and strong fire and soundproofing properties. Earthwool is more dense and durable than fiberglass insulation. The installation process may require some expertise and the use of protective gear, but it’s a sustainable and energy-efficient choice for your shipping container project.
