In todays video, Channing introduces a new window prototype that's in development by Container Modification World. This product is not for sale yet, but we did say we'd share all our secrets. These windows are being designed with a built in marking tool, rain drip, less materials and many more improvements. Stay tuned for future videos on how to assemble these new frames.

New 42 Inch Sidewall Window Frame Update from The Container Guy

Channing McCorriston, The Container Guy, introduces the newest prototype window frame from Container Modification World and explains how it improves material efficiency, water management, insulation integration, and inventory simplicity.

This update focuses on refining performance while reducing cost and complexity.

Major Design Improvement: 60 Percent Less Material

The new 42 inch sidewall window frame replaces the previous 48 inch version for sidewall applications.

Key improvements:

• Frame profile reduced from 2 inches to 1 inch

• 60 percent less material used

• Reduced weight

• Lower shipping cost across North America

• Lower overall product cost

The slimmer profile maintains strength while significantly improving efficiency.

Updated Raindrip Water Management Profile

One of the most important upgrades is the new raindrip style profile.

Benefits:

• Directs water to drip in front of the window

• Prevents water from reaching the vinyl nailing fin

• Eliminates header pooling issues

• Reduces reliance on excessive sealants

This design dramatically improves long term moisture protection.

Simplified Window Sizing Strategy

Previously, multiple window sizes were stocked.

Now inventory is streamlined to:

• 42 inch window for sidewalls

• 48 inch window for end walls

This reduces the lineup from eight sizes to two, simplifying:

• Inventory management

• Customer decision making

• Production efficiency

The 42 inch window is considered fully adequate for commercial and industrial container sidewall applications.

Self Assembly Frame Design

The new frame is designed for self assembly.

Features include:

• Four piece construction

• Clean folded steel profile

• No hollow sections

Eliminating hollow steel reduces thermal transfer and prevents cold bridging from exterior to interior.

Insulation and Vapor Barrier Integration

The frame is designed to integrate cleanly with spray foam insulation.

Installation method:

• 2 pound closed cell spray foam

• Foam applied tightly up to the vinyl window

• No foam injected between framing members

• Continuous vapor barrier formed

This approach has been used for four to five years without cracking or failure.

The result is a tight, durable building envelope.

Thermal Performance

The folded steel profile:

• Contains no hollow steel sections

• Reduces cold transfer

• Eliminates internal condensation risk at the frame

Spray foam sealing creates a seamless transition from wall to window.

Future Insulation Development

There are plans to develop insulation solutions for remote locations where spray foam contractors are not available.

Potential future system may combine:

• Rigid foam

• Mineral wool

The goal is maintaining a healthy building envelope without relying solely on spray foam installers.

Old vs New Frame Comparison

Key Takeaways from The Container Guy

• 60 percent material reduction lowers cost and shipping weight

• Raindrip profile significantly improves water management

• Simplified inventory improves efficiency

• Spray foam integration creates strong vapor barrier

• No hollow steel eliminates thermal bridging

• 42 inch sidewall window is sufficient for commercial builds

This update represents a cleaner, lighter, and more refined window frame solution for container modifications.
