In 1962, Won-Door Corporation introduced the world’s most durable acoustically rated folding partition – DuraSound. Fifteen years later the company pioneered the development of the first-ever accordion type, fire-rated horizontal sliding door. Technology developed by Won-Door engineers continues to influence the building products and fire protection industry. Click here to see why Won-Door FireGuard is the top-selling horizontal sliding fire door on the market.
The development of the accordion type, horizontal sliding fire door – as manufactured by Won-Door Corporation – has had a profound influence on the model requirements that regulate their use. They may replace traditional solutions in virtually any means of egress application.
The Won-Door FireGuard fire door was the first accordion type fire door to successfully pass nationally recognized tests to withstand the passage of fire. Won-Door FireGuard products are listed by Underwriters Laboratories Inc. (UL) for up to 3 hours as a rated door assembly and 2 hours as a moveable fire wall.
Only the Won-Door FireGuard uses a state-of-the-art microprocessor activated control system to guarantee reliability and enhance door function.
This technology provides almost limitless opportunities for electronic communication, supervision, alarm activation and more.
All Won-Door products are built to withstand the test of time. Constructed of 24-gauge corrugated steel and with no exposed parts, these door assemblies are the most trouble-free accordion folding partitions in the industry.
