SELECT A TYPE OF DURASOUND DOOR
Won-Door DuraSound™ accordion folding doors increase building utility by performing multiple functions. These versatile accordion partitions are competitively priced, cost less to install and maintain, and last years longer than any other folding partition on the market.
The dual-wall DuraSound accordion folding partition has the highest sound rating (STC 48) in the industry. Each steel panel is corrugated for extra strength. Surface colors and vinyl finishes are permanently bonded. The result is a partition that is dent, ding and scratch resistant.
DuraSound™ doors are only 4.2 pounds per square foot – and operate on a two-track system. A pin and roller suspends every panel and promotes smooth and low effort operation. This unique design allows the doors to span large, as well as curved, openings. Available in unlimited widths, heights up to 28 feet*.
