Vision Windows

Improve aesthetics and visibility with one- or two-way windows incorporated in the curtain.  For rolling steel doors, each pane is 10" x 1 5/8" and must be spaced 2" apart. The minimum spacing in from each guide is 12".

Please note, adding vision windows to insulated doors may impact Sound Transmission Class performance.

For rubber doors, each pane is 16’ x 16’, with one window per 5’ of DW maximum.
