The Best Shipping Container Insulation Methods

Insulating your shipping container is important if you plan to spend any time in it. Depending on where you live, the climate can be unforgiving, with scorching summer temperatures and bone chilling winters. Even though we’ve seen container repurposing skyrocket, shipping containers weren’t designed to be a habitat for humans. They are made of steel and are vulnerable to condensation. Proper insulation is essential – not only for your comfort, but also to keep your container in good condition by avoiding mold and rust.

Foam Insulation

Spray foam insulation is an ideal method of keeping your container warm in cooler months and dry in damper months as it combats condensation and creates a seamless vapor barrier. It’s also the swiftest method of insulation and is very flexible, allowing you to spray into gaps of all shapes and sizes.

Spray foam insulation can be applied on both external and internal walls of your shipping container, and you can also spray it underneath your container to stop any moisture from the ground seeping in. Once the foam has dried you can easily paint it in order to make your container space more ascetically pleasing.

The downside of using spray foam insulation is that it’s more expensive and a lot messier to work with compared to other insulation methods.

As well as spray foam insulation, there are a number of different types of insulation which can be safely and effectively used for your container, such as:

  • Insulation panels
  • Blanket insulation
  • Eco-friendly options of wool or cotton

You can even choose to use a combination of different insulation types to tackle precise needs. For example, spray foam can be used to prevent condensation, and panels can be installed to control interior temperatures.

Insulation Panels and Blanket Insulation

These types of insulation methods are very “weekend warrior” friendly, but require stud walls to fit them into place.

Insulation panels can be bought at predefined sizes and then fitted in the gaps of your stud wall. The panels have a high insulating value for their relatively small depth, so if you don’t want to spend a lot of money on foam insulation, panel insulation may be an affordable solution that still keeps insulation thickness to a minimum.

Blanket insulation, while taking a little longer to install than panels, is the cheapest of the insulation methods. The most common blanket insulation is mineral, and is also known as rock wool. Some types of blanket insulation are made from fiberglass which makes installation a little more difficult as care is needed when handling. Personal protective equipment should be worn for safe installation.

Natural Materials

If you’re looking to insulate with natural materials and avoid those such as fiberglass, then one of these insulating methods could be the right fit for you:

Wool Insulation

This method uses sheep’s wool and is similar to blanket insulation.

Cotton Insulation

This method is similar to blanket insulation but uses recycled cotton instead of fibreglass.

Living Roof

During the warmer months a living roof can reduce indoor temperatures by up to 8 percent, however it isn’t a replacement for proper insulation.
