How to Insulate a Container House

As we know, modular container houses are very popular buildings in the field of temporary construction, and they are used more and more frequently in various industries. With the continuous development of container houses, the demand for containers is also rising. 

Container houses are generally made of steel structures, color steel plates, wall sandwich panels, flashings, doors and windows, self-tapping nails, rivets, and other materials. If you're going to buy a container house, you must be curious about how to insulate a container house.

In this article, I will introduce different insulation materials and how to choose the most suitable insulation material according to your local climate, to make the people living inside feel very safe and comfortable.

What Is Container Insulation?

Compared with traditional buildings, the wall panels of container houses are thinner, the metal has thermal conductivity, and the thermal insulation performance has a certain gap compared with traditional buildings. However, if you choose suitable insulation materials and equip your container house with high-quality insulation materials, you can not only ensure that everyone in the house feels warm in winter and cool in summer. And also save energy.

Insulation Materials for Containers

There are many different insulating materials for the wall panels. Such as EPS sandwich panels, rock wool board, PU sandwich panels, etc. These insulation materials have their own advantages and disadvantages. How choosing the best suitable wall panels, needs to be based on the local climate, and the environment of the construction site.

1.EPS sandwich wall panels for containers

EPS sandwich panel, also called polystyrene sandwich panel, is a sandwich panel made of foam. It has the characteristics of light weight, quick installation, and light weight, and can be plugged, installed, and cut at will. But the fire performance is poor.

2.Rock wool sandwich wall panels for containers

The rock wool sandwich panel is a sandwich panel made of rock wool. Rock wool sandwich panels give full play to the unique properties of rock wool core materials and have significant effects on fire prevention, thermal insulation, sound absorption, and sound insulation. The disadvantage of the rock wool sandwich panel is that its strength is not strong enough, but it is suitable for steel structure workshops, roofs, and walls of simple mobile houses, ceilings, and partitions of air clean rooms, etc.

Rock wool sandwich panels give full play to the unique properties of rock wool core materials and have significant effects on fire prevention, thermal insulation, sound absorption, and sound insulation. Because of its high-cost performance, it is often the preferred insulation material for container houses. The raw materials, production process, and formula used in rock wool sandwich panels make it have good fire resistance. Tests have shown that it has a fire resistance of over 1000°C. In addition, the thermal insulation performance of the rock wool sandwich panel is very good, and the thermal conductivity is 0.043W/㎡K. The rock wool sandwich panel has a significant reduction effect on noise transmission and is especially suitable for places where designated flights pass. Rock wool sandwich panel also has an excellent attraction effect.

3.PU sandwich wall panels for containers

PU sandwich panel is a sandwich panel made of rigid polyurethane. Polyurethane sandwich panel composite panels have low thermal conductivity and good thermal insulation performance and are currently the best thermal insulation materials. The polyurethane sandwich panel has a beautiful appearance and a good overall effect. It integrates load-bearing, thermal insulation, fire prevention, and waterproofing, and does not require secondary decoration. It is fast and convenient to install, has a short construction period, has good comprehensive benefits, and has a good cost-effective advantage. It is a kind of it is a highly efficient and energy-saving building insulation material with a wide range of uses and great potential. The price is more expensive than rock wool sandwich panels and EPS sandwich panels.

To sum up, K-Home will supply the container house with the most suitable insulation material according to the local climate and budget.
