It is becoming more and more popular as a form of modified shipping containers to insulate the interior of a shipping container or storage container. There are several different ways to go about doing so. The more commonly used materials for containerized applications are fiberglass, rigid polystyrene foam panels and closed cell spray foam. There are also some coatings on the market that offer insulating qualities as well. However, for the purposes of this article, we are going to discuss the three options mentioned.
Shipping container spray foam is quickly becoming my go-to method of insulation. Some framing is still necessary here, but spray foam insulation is applied as the walls are installed to keep it inside. The pros - you can get insulation into every nook and cranny in the corrugation of the walls, increasing your r-factor and reducing condensation, and a good r-factor can be reached with narrower walls. The cons - it takes a little more know-how to get the application just right (however there are companies that will do that part for you) and the cost can be a little higher than traditional roll insulation. Overall, I think it is a good mix of price and value.
Shipping containers should be insulated when the goods being transported could be potentially and negatively affected by extreme fluctuations in temperature.
Combating condensation and dampness within a container is also a concern, especially on long hauls, and is crucial when transporting goods which may react adversely to these conditions such as linens, fabric, clothing, furniture, certain metal item which may be prone to rust and many more.
Spray Foam is also ideal when applied to containers which house their own cooling or freezing units which keep the contents such as meats and vegetables from perishing. Actually, all products that you find in the frozen and refrigerated isles of your local supermarket have been transported by similar means.
Shipping containers are also now being used for other purposes. Some of these include, complete homes, schools, storage units, cafes, offices on building sites, kiosks, urban toilets, workshops and garages.
When used in a building block fashion, apartments, restaurants, art galleries, office blocks, and even hospitals have been built.
Closed Cell Spray Foam is denser, rigid and impermeable to both air and water. Mainly used in commercial, agricultural and industrial application where moisture and temperature control are required.
The reasons why spray foam insulation is the ideal material to insulate containers are numerous.
Spray foam completely covers the surfaces of the corrugated metal shipping containers walls, ceiling and floor.
