4” Platform
Enclose Frameless Glass Walls

The 4” Frameless Glass Wall Platform is a site built progressive system composed of individual components that are factory-cut and assembled on site. It’s dimensionality is compatible with other the other 4” Platform options, but with a very low base profile, creating visually minimal framing. As part of the broader family of 4” Platforms, this site built Glass Wall System works in concert with solid wall applications to balance visibility, privacy, acoustics, and performance.
