BW Universal System™

Metl-Span’s BW Universal System™ is the ultimate backup horizontal backup wall system that provides superior air, water, thermal and vapor protection in an all-in-one barrier component. It can be horizontally installed with nearly any type of exterior rainscreen system, from single skin and modular metal to brick and ACM panels. This unique insulated metal panel wall system, which spans up to 24” o.c., introduces new standards when it comes to cost savings, design integrity, and sustainability. The BW Universal System eliminates the need for multiple work crews as it is quickly installed in a single step. It not only expedites close-in/dry-in building times, but rather reduces the likelihood of improper installation as well.
