Wall Systems

Backup Wall


Metl-Span’s backup insulated metal panel systems provide superior air, water, thermal, and vapor protection in an all-in-one barrier wall component. Our BW Universal System can be installed horizontally with nearly any type of exterior rainscreen system. Our BW Stretch System can be installed vertically, spanning up to 6 feet on center. These unique insulated metal wall panel systems introduce new standards in cost savings, design integrity, and sustainability.

Backup wall systems are a great option for any type of building, as they contribute to faster construction and a more energy-efficient structure. Our flexible backup wall systems offer a superior all-in-one component design, improving on traditional multi-component wall construction. This allows for easy, one-step installation and eliminates the need for multiple installers, streamlining the construction process. As a single-source option, responsibility is consolidated to one manufacturer and installer.

A few examples of applications include:
