Types of Insulation Panels for Shipping Containers

When it comes to insulating your shipping container, there are several types of panels to consider. Each type has its own benefits and drawbacks, making it important to choose the right one for your specific needs.

Foam Insulation

Foam insulation is a popular choice due to its high R-value, which means it provides excellent thermal resistance. There are two main types of foam insulation:

1. Spray Foam Insulation

Spray foam expands to fill gaps, creating a seamless barrier against air leaks and moisture. It’s highly effective for maintaining a stable temperature inside your container. Closed-cell spray foam is particularly advantageous because it offers the highest insulation value—approximately R-6 per inch. This type of insulation is also great for preventing condensation.

Polystyrene panels are made from expanded polystyrene foam. They are injection-molded and designed to fit the corrugations of shipping containers. These panels are lightweight, easy to install, and provide excellent insulation.

Living Roof

A living roof, or green roof, involves planting vegetation on the roof of your shipping container. This natural insulation method not only helps regulate temperature but also offers sustainability benefits.

1. Green Roof

A green roof provides natural insulation and helps reduce the heat island effect. It’s a sustainable option that can make your shipping container more energy-efficient. However, it requires a strong roof structure and proper waterproofing to prevent leaks.

Choosing the right insulation for your shipping container depends on various factors like climate, budget, and specific needs. Next, we’ll dive into the benefits of using insulation panels in shipping containers.

Condensation is a major issue in shipping containers due to the metal walls. Moisture can lead to rust, corrosion, mold, and mildew, which can compromise the structural integrity of the container and pose health risks.

Closed-cell spray foam insulation is highly effective in preventing moisture build-up. It expands to fill gaps, creating a seamless barrier that keeps moisture out. InSoFast’s CX44 panels are also designed to fit the corrugations of shipping containers, further minimizing the risk of moisture infiltration.

Noise Reduction

Shipping containers can be noisy due to their metal construction. Insulation panels help dampen external noises, making the interior quieter and more comfortable.

InSoFast foam panels not only insulate against temperature but also provide excellent soundproofing. This is particularly beneficial if you’re converting your container into a living space, office, or classroom.

Durability

Insulation panels add an extra layer of protection to your shipping container, enhancing its durability. They guard against temperature fluctuations, moisture, and physical damage, extending the lifespan of your container.

Rigid foam panels like polystyrene are particularly durable. They are injection-molded and resistant to moisture, making them ideal for both interior and exterior applications.
