How to make Shipping Container more Secure?

Shipping containers are designed for transporting different goods around the world on boats, trucks, and trains, but now they are used for offices as well as houses. These steel boxes are some of the most durable structures we had. Most containers’ size is all about 8-feet wide, and 40 or 20 feet long.

Insulation of Shipping Container:

Insulating a shipping container is essential for preventing condensation or when we have decided to convert shipping containers into office/home. Shipping container insulation may be costly, that’s why some people would like to do it on their own, but on the other hand, some people hire some professional to get the job done. In this blog, we’ll cover the necessary process involved with insulating a shipping container with the best materials. It’s essential to make sure that according to the usage of a shipping container will need a different sort of insulation. For this reason, this blog is for guidance only, and we can make no guarantees that our recommendations can get you performance as per your expectations.

How does it work?

It’s possible to insulate a transport container in many ways such as adding insulation and ply-lining, including one of our custom made insulating material, or by merely applying spray foam. But before selecting the best alternative, you need to think about the climate wherever your container will be found. For example, if there is a container where the weather is very cold, then you want an extremely thick layer of insulating material. Also, the home conversion may require different insulation kind to a workplace, along with a workplace that will require different insulation to some simple storage container. The fundamental procedure for lining insulating a delivery container is quite straightforward. First, you construct an inner frame in your transport container. Your inner wall is going to be mounted on this framework.

Benefits of Insulating a Shipping Container:

  • It allows you to stop spiking temperatures by the formation of mould.
  • Goods remain fresh for more time with less cost.
  • Offices can be established everywhere while a comfortable working environment is available in these containers.
  • Accommodation for the low-cost homes could be provided with the additional advantage of luxury interior look.
  • Different Cargo products could be saved from hot weather with the help of these containers
  • It also stops rainwater from getting within the container and minimize condensation.

Types of Insulating a Shipping Container:

Basically, any material with insulating properties can be used as a shipping container insulation material. We typically use the following methods:

  • Spray Foam Insulation
  • Cotton Insulation
  • Wool Insulation
  • Cork Insulation

Spray Foam Insulation:

One of the simplest and easiest ways to insulate a container house is by using spray foam insulation. This insulation material can be sprayed directly on the exterior and interior walls of a container. Many shipping containers have been coated with exceptionally poisonous paints to withstand life. Spray foam insulation may snare the VOCs, which could lead invisibly to your property. However, the EPA has recognized possible health dangers associated with polyurethane spray foam insulation, such as asthma, lung damage, and other respiratory disorders. Icynene is a water-blown spray foam insulation product that expands because it hardens and consequently insulates a house through miniature plastic bubbles that form in the inside of the insulating material. While many different forms of polyurethane spray foams can off-gas chemicals to your home, a little number of VOCs related to Icynene insulation will almost certainly be utterly undetectable between 2-3 weeks.

Cotton Insulation:

The most important feature of sustainable houses and buildings would be easy construction and reutilize as far as you can. Many companies now offer organic, cotton-based insulating material made from recycled, post-consumer cotton, and denim sourced from utilized jeans and other clothes products. Cotton insulation comes with an R-Value of 3.5 per inch, very similar to that of traditional fibreglass insulation. Moreover, commercial denim insulation is generally treated with acid, a natural flame retardant. On the other hand, it is essential to take a vapour barrier for denim insulation.

Wool Insulation:

It is another of the best and easiest insulation options sourced from natural and renewable substances. This highly proficient and environmentally friendly insulation possesses an R-value of 3.5 per inch, very similar to that of lace, fiberglass, or other fibrous insulation kinds. Moreover, the lanolin in sheep wool is a natural fire retardant, which makes it unnecessary to take care of the wool along with other chemical alternatives. Before going outside to get a couple of sheep, many organizations are specializing in selling sheep wool insulation products. These companies provide various types of sheep wool, and some come with organic condensation control. The hygroscopic fibers in sheep wool can absorb up to 35 per cent of its weight in water without changing its working.

Cork Insulation:

Cork insulation is also one of the best insulation options for shipping container houses. Cork is a renewable and biodegradable resource, and it can be extracted from trees. Surprisingly, pine trees don’t need to be cut to harvest the cork, but instead, the bark in the trees is harvested every nine decades. This harvesting process produces cork “carbon adverse”. The acoustic of cork is still another advantage of cork insulation for shipping container houses. This pure insulation will form a space between your home and the metallic walls of the container, and that could protect the walls of the box.


In this blog, we have discussed some useful insulation methods. These methods are dependent on weather conditions as well. So we can say that if you have decided to insulate a shipping container, then you can pick from one of these according to your needs. Good Luck!
