Provide “invisible,” code-complying fire protection while creating dramatic spaces.


Why FireGuard?

The Gold Standard in Fire Protection

Since its inception more than 40 years ago, the original fire-rated, horizontal-sliding accordion door continues to influence building code requirements and provide design professionals with unmatched flexibility and peace of mind.

The Gold Standard in Fire Protection

Design Versatility

From the most narrow of corridors and the shortest of ceilings to openings that span over 200’ wide and 35’+ tall, FireGuard gives you the versatility to protect any size opening.

Curved Configurations

Flow with the gradual curve in your design or snake around structural elements. Custom radii are available to as tight as 5’.

Secure Solution

An effective deterrent to unauthorized visitors while maintaining an open plan design, FireGuard can replace traditional solutions for virtually any means of egress or access control.


FireGuard + Access Control

My fire door can also be used as an access control checkpoint?

Using any of the following security components and features, Won-Door’s FireGuard™ accordion folding fire door has the ability to both serve as an opening protective in a means of egress AND as an access control device during after-hours events or off-hours lockdown.  Design your new space using FireGuard + Access Control or retrofit an existing FireGuard door to have the best of both worlds – a fire-rated opening protective + an access control device.
