Designing narrow corridors and compact openings has never been simple. Architects and facility planners are often expected to balance fire protection requirements, accessibility, traffic flow, and aesthetics, all within a limited footprint.
In many buildings, especially healthcare facilities, schools, and commercial spaces, traditional fire-rated swing doors can quickly become part of the challenge rather than the solution. Door leaf clearance, protruding hardware, and bulky frames can interrupt circulation paths and make already tight spaces feel even more restrictive.
That’s where Won-Door FireGuard™ Slim changes the conversation.
Designed Specifically for Tight Spaces
FireGuard Slim was developed to solve one of the most common design problems in modern construction: how to provide reliable fire protection in narrow corridors and smaller openings without sacrificing openness or functionality.
Unlike traditional side-hinged swing doors, FireGuard Slim remains neatly stacked and virtually out of sight during everyday operation. When activated by a fire alarm or smoke detector, the accordion-style fire door automatically deploys to create a code-compliant fire and smoke barrier.
The result is a safer, more flexible environment that preserves corridor width, improves visibility, and supports smoother pedestrian movement.
A Cleaner Architectural Aesthetic
Today’s buildings increasingly prioritize daylighting, visibility, and open-concept layouts. Traditional swing doors can interrupt those goals by visually cluttering corridors and limiting openness.
FireGuard Slim helps architects preserve a clean, minimalist appearance while still meeting fire and smoke separation requirements. Its industry-leading 14-inch stack depth allows the door to retract into a compact pocket, minimizing visual disruption and maximizing usable space.
This creates a more modern and welcoming atmosphere without compromising code compliance.
Built for Modern Life-Safety Demands
FireGuard Slim is available with fire ratings up to 90 minutes and is designed for applications up to 9 feet wide in 7- or 8-foot heights.
Its automatic deployment helps contain fire and smoke while maintaining safe egress pathways during emergency situations. The system also supports optional remote monitoring and specialized configurations such as the “SE” label for elevator access applications.
More importantly, it gives architects and building owners greater freedom to design spaces that feel open and functional every day, not just compliant on paper.
Specifiable Options Include:
- Industry-leading 14” stack depth for minimal visual and spatial impact
- Available in openings up to 9’ wide
- Offered in 7’ and 8’ heights
- Fire-rated up to 90 minutes
- Optional remote monitoring capabilities
- New “SE” label option allowing use at the point of access to an elevator car
Rethinking Fire Protection in Small Openings
Narrow corridors and compact openings no longer have to force a compromise between safety and design.
FireGuard Slim represents a smarter alternative to traditional swing doors by combining code-compliant fire protection with better traffic flow, improved aesthetics, and more efficient use of space.
Fire Protection That Fits the Space
Smaller openings shouldn’t force oversized compromises.
As buildings continue prioritizing accessibility, efficiency, and occupant experience, fire protection systems need to adapt alongside them. Solutions like FireGuard Slim allow architects and facility owners to meet fire and smoke separation requirements while maintaining the open, functional environments modern buildings demand.
Because in narrow corridors, the best fire protection solution is often the one that works seamlessly in the background until it’s needed most.
