Insulation is crucial when you’re building a shipping container home. Without it, your house will either be searing hot or freezing cold, making it uncomfortable for people living in it. While many opt out of insulation to save money, they will eventually realize how important it is when they start feeling the impact of changing weather.

Climate is a major factor in choosing the type of insulation you’ll use for your container home. If you’re in an area that’s too cold, you would need to protect your house from condensation and to keep it warm at most times. For hot areas, you’ll need to keep it cool.

Once you figure out how you need to insulate your home, you can then choose the type of insulation.
