  3. At the back of the panel, add adhesive along the ribbing area.
  4. Make sure to install the wall panels before you add the ceiling panels.

Insulating the side of the shipping container walls (STEP BY STEP)

  1. Cut out the insulating material in the right measurements that you need.
  2. Now apply the adhesive in a zig zag manner on the surface area where you want to place the insulating material.
  3. Push in the panel tightly packed close to each other so that there is no space in between the insulating panels.

  1. Duct tape the panels together so that you get a stable base
  2. Add layers of adhesive on the base of the wall
  3. You can also use spray foam to help create a kind of moisture and air seal that will form between the rows of the panels.
  4. Now strongly hold the base that you created earlier and place it on the wall.
  5. Make sure that you fit it in tightly and push it hard on the wall so that there is no gap anywhere.
  6. For the wall panels, you can use tubes of Loctite PL Premium or any other similar product that you want to use.
  7. This is the same procedure you will have to use to insulate the entire wall as well as all the walls in the shipping container home.

What is the best insulating material to use for a container home?

There is no one material that you can use as the best insulating material for all shipping container homes. The material that will work the best for your shipping container will depend on a number of factors. Here are a few things that can help you decide about the material you want to use for your shipping container home:

Option #1

The climate and weather:

  • Choose a material depending on where the shipping container home will be.
  • This will vary based on whether the climate there is usually very hot or very cold.
  • You will need different types of insulating materials depending on whether you will use the shipping container home in a wet or dry climate.

Option #2

Cost:

  • You should also keep in consideration your overall budget.
  • Have an idea in advance of how much you are willing to spend on the insulation.

Option #3

Air infiltration:

  • If a lot of air will come in through your container home, it could affect the insulation.
  • Using fibreglass or mineral wool may help.

Option #4

Overall home area:

  • The surface area of the home will play a role in how much heat gets absorbed.
  • When you have a bigger area, you need more insulation.

Option #5

Problem of rusting:

  • If you are setting up the shipping container home in a wet climate, it can be quite damaging to the shipping container in the long run and lead to problems such as rusting.
  • Regular exposure to water can end up causing rust on the steel container and pose problems in the future.
  • Also, condensation can lead to problems in the interior of the shipping container, so choose the material wisely.  

Other Things to keep in mind when you insulate a shipping container:

  • Make sure that you are insulating all the surface area of the shipping container.
  • There should not be any gaps or open areas in between the panels of insulation that you are putting up on the walls.
  • If you do not insulate properly and there is some space left between the insulated parts, it could cause a lot of condensation to take place on the inside parts of the metal walls on the outside.

Some of the most common shipping container insulation materials:

  • Cellulose
  • Fibreglass
  • Natural fibres
  • Mineral wool
  • Cementitious foam
  • Polyisocyanurate
