Just like doors, windows completely change how a shipping container feels and functions. A container without windows works fine for storage, but once you want light, ventilation, or customer interaction, you’ll need to cut openings and frame them in.
Let’s walk through the main types of container windows, their uses, and the basics of how to install them, plus where Container Modification World (CMW) products can save you time and hassle.
Types of Windows for Containers
1. Fixed Windows
Fixed windows don’t open, but they bring in natural light and make a container feel more inviting.
- Best for: Offices, living spaces, or display containers.
- Pro Tip: Use CMW’s Pre-Framed Window Kits for a quick, weld-free install.
2. Sliding Windows
Sliding windows provide both light and airflow. They’re compact and don’t require clearance to swing open.
Basic Installation Steps
- Plan Your Placement – Mark your cutout in a location that works with your container’s framing.
- Cut the Opening – Use proper PPE and clean tools to cut through steel walls.
- Frame the Opening – Reinforce edges to prevent flexing. CMW’s framing kits make this step weld-free and precise.
- Fit the Window – Place the window into the framed opening and secure it.
- Seal & Flash – Use flashing kits and sealant to stop leaks and drafts.
- Interior Finish – Tie into your wall system for a polished look.
Final Thoughts
Adding windows is about more than aesthetics — it improves livability, functionality, and airflow in any container build. The key is cutting clean, reinforced openings and sealing them properly.
With CMW’s Window Kits and Flashing Systems, you can install windows that look professional, stay weather-tight, and last for years, all without welding.
