Won-Door DuraSound-XL™ accordion folding doors were designed for spaces where pocket depth is of greater concern than pocket width, like gymnasiums and auditoriums. DuraSound-XL™ are similar to the DuraSound™ doors in that they both increase building utility by performing multiple functions. These versatile accordion partitions differ from the standard DuraSound™ door by utilizing a wider panel to greatly decrease the stack depth with a proportionately marginal increase in width.
The dual-wall DuraSound-XL™ 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-XL™ doors are only 4.2 pounds per square foot – and operate on a two-track system. A pin and roller suspends every panel, promoting smooth and low-effort operation. This unique design allows the doors to span both large and curved openings. Available in unlimited widths; heights up to 28 feet*.
*For doors above 15 feet tall and/or 30 feet in length motorized units are recommended.
