BioSafe Cleanroom Switch Glass Window Panels

Now you see it; now you don't! Switch-Glass Window mounted in Stainless Steel BioSafe Cleanroom (Shown: 6603-43)

  • Versatile laminated panels with tempered-glass outer layers become conventional viewing windows when energized, opaque privacy panels when de-energized
  • Forms a curtain wall to provide patient privacy in healthcare facilities
  • Ideal for on-demand viewing of sensitive or high-security operations inside medical, pharmaceutical, aerospace and other manufacturing operations
  • Available in BioSafe® framed and frameless designs for use in Terra modular cleanrooms or conventional walls of any thickness (more information)
  • Select standard sizes below or specify custom panes in any size or shape

BioSafe Switch-Glass Privacy Windows provide an elegant, energy-saving way to alternate between viewing windows and privacy panels in a host of industrial, research and government applications.

Operated via a wired switch or WiFi remote control, these laminated panels include a liquid crystal layer that provides 97% light transmission when activated by 65V current. When de-energized, the panel switches to a partially opaque appearance that provides full privacy. The dual-side tempered-glass lamination ensures the same characteristics, including smooth, chemical-resistant surfaces, of standard windows, making these panels easy to clean.
