FireGuard Moveable Fire Wall — Insulated Accordion Fire Wall
Description

Won-Door FireGuard Moveable Fire Wall is a horizontal sliding accordion fire door which sits concealed away inside a pocket cavity, closing automatically under an alarm activation — FireGuard Moveable Fire Wall (MFW) is Won-Door’s insulated model fire door. 

When the Building Code restricts the size of penetrations in a fire barrier, the MFW is an alternative performance solution that is UL Certified as meeting the criteria required by ANSI/UL263 (ASTM E-119, NFPA No.251). FireGuard MFW provides designers a solution to open up spaces while still being able to quickly shut them down and create safe passages in the event of fire.  Two options are available; MFW1 (-/60/60) and MFW2 (-/120/120) with maximum opening dimensions of 9.144m wide and 3.740m tall.

The concealed pocket offers architects a completely hidden fire separation solution for compartmentalising buildings, while still maintaining clear unimpeded sight lines. Manufactured in America by Won-Door Corporation, FireGuard incorporates a steel twin walled design operating on twin top-hung tracks — there are no floor tracks required. Opening up design capabilities for architects in areas such as lobbies, atriums, stairways and corridors. A reliable and completely hidden solution.
