PERFORATIONS
PERFORATION SELECTOR
Standard perforation patterns and selected finish options are shown below. A wide
array of custom perforations and unique finishes can be created to achieve your
specific design objectives. Contact Gordon for details.
Please contact Gordon for design assistance with your guide specifications. Not
all perforations can be used with every application. Material type, thickness, module
size, and ceiling type must be taken into consideration when selecting the appropriate
perforation pattern.
