Polyurethane foam

Polyurethane foam is directly sprayed and is one of the most practical insulators to apply. This involves spraying it on the interior or exterior walls of your container house.

What are the challenges of insulating a container house?

When you want to insulate your container house, several challenges generally present themselves.

Insulating a container house: pay attention to the shallow depth of the walls

Although the wall is not made to last over time and has a certain resistance, it is true that the walls are often thin. This poses a first challenge for properly insulating your container house. To resolve this problem of wall depth, you must consider the size of your container house.

If your interior space is large enough, you can opt for interior insulation even if this reduces your living space. On the other hand, if you have a relatively small interior surface area, do not hesitate to opt for high-performance exterior insulation.

The use of steel as the main component of your container house

The container house is mainly made of metal, which means that interior temperatures are greatly impacted by exterior temperatures. Indeed, the interior in summer is very hot while temperatures drop considerably in winter.

Despite the use of steel, it is therefore necessary to provide suitable insulation to allow you optimal living comfort.

How do you install insulation in a container?

Setting up the extended form is very simple – simply attach it to a stud or mount it directly onto a shipping container. Additionally some varieties are also inserted into these corrugated areas to match the corrugation of the shipping container wall to avoid large air gaps. This way it becomes more secure to install the form.

There is another way to set up the form in different stages through this process. First you need to choose the location to install the form, then move it and finally add it securely. It is important that you follow proper safety precautions throughout this process to avoid any untoward incidents.
