Once you’ve framed and insulated your shipping container, the next step in your build is finishing the walls. This is where your space really starts to take shape, and how you finish the interior walls can have a big impact on looks, comfort, and long-term durability.
In this lesson, we’ll walk through the most common wall finish options, how they perform in container environments, and how to install them properly over steel framing systems.
First, Ensure Proper Framing and Insulation
Before you touch drywall or panels, make sure you’ve:
- Installed proper framing (wood or steel studs)
- Added insulation (spray foam is ideal)
- Run electrical/plumbing
- Sealed around all doors, windows, and penetrations
Need help? Our steel stud framing brackets create an air gap for spray foam and attach without welding, perfect for container walls.
