Won-Door FireGuard Slim
Open up your corridors without sacrificing life safety. Won-Door FireGuard Slim is a compact, fire-rated accordion door engineered specifically for narrow corridors and small openings where every inch of space matters. It’s the smart, modern replacement for conventional fire-rated swing doors in schools, hospitals, offices and other high-traffic environments. Instead of bulky swing doors that block sightlines, create bottlenecks and require expensive frames and hardware, Slim disappears neatly into a minimal pocket and only moves when it’s needed most.
In everyday use, FireGuard Slim stays fully stacked, preserving the full width of the corridor for free-flowing traffic and clear visibility. When activated by a fire alarm or smoke detector, the door deploys automatically to provide code-compliant separation and protection, with fire ratings available up to 90 minutes for peace of mind in demanding occupancies.
Designed as a true alternative to traditional swing doors, FireGuard Slim delivers a clean, minimalist aesthetic that aligns with modern interiors. Its compact head track and industry-leading 14″ stack depth help improve daylighting and maintain open, airy views while still meeting stringent life-safety requirements. Available up to 9 feet wide and in 7- or 8-foot heights, Slim fits common corridor and opening sizes in education, healthcare, office, hospitality and mixed-use projects.
FireGuard Slim is as practical as it is attractive. Installed costs are similar to those of swing doors, yet Slim eliminates the need for metal frames, surface hardware, astragals, magnetic hold-opens and many other accessories, reducing both first cost and long-term maintenance. Integration with the building’s fire alarm system is straightforward, and optional remote monitoring supports modern facility management.
For projects that demand added performance, the Slim SE option allows use at the point of access to an elevator car and helps meet stringent smoke and draft control requirements without an obtrusive bottom seal—ideal for elevator lobbies and smoke compartmentation strategies.
FireGuard Slim gives architects, contractors and owners the freedom to open up more space, simplify corridors and elevate design, while still delivering reliable, tested fire protection when it matters most.
