Won-Door Accordion Doors

The development of the accordion type, horizontal sliding fire door – invented by Won-Door Corporation – has had a profound influence on the model code requirements that regulate their use. They may replace traditional solutions in virtually any means of egress application.

For the best possible stack depth and more standard features than ever before, we recommend using Won-Door FireGuard AFG for all straight single parting applications less than 40′-0″ in width and 15′-0″ in height. *Some restrictions apply, please see individual product pages for more details.


FireGuard AFG

The Won-Door FireGuard AFG sliding fire door allows the unimpeded flow of pedestrian traffic as well as open plan designs while having standard and optional advanced access control features. All AFG products are manufactured in incremental dimensions and can accommodate any straight single parting door up to 40′-0″ in clear opening width and 15′-0″ in height with .1WC air pressure differential or less.


FireGuard FG

Won-Door FireGuard sliding fire door allows the unimpeded flow of pedestrian traffic as well as open plan designs. All FG products are manufactured to custom sizes per application and can accommodate any width opening, heights up to 30′-0″, bi-parting, and curved configurations.


FireGuard MFW Moveable Fire Wall

Moveable Fire Wall is a separate fire-resistive rating for Won-Door FireGuard. When code restricts the size of penetrations in a fire barrier, the MFW is an alternative that meets the requirements of ASTM E-119 and can be used to protect large openings.
