Metl-Vision® and Envelope Solution

Metl-Span has developed the Metl-Vision® window system to further complement the exceptional architectural aesthetics and function of Metl-Span’s horizontal wall panels.  Metl-Vision is the first window system with a flush frame designed to fully integrate with the Metl-Span 2” and 3” horizontal wall panel to ensure a weathertight installation.  The system offers great flexibility in window size, multiple lite configurations and window finish options.  The finished assembly eliminates interface problems common with standard windows mated to Metl-Span wall panels that are horizontally applied.
