Modernfold manufactures operable partitions, glass wall systems and accordion doors for interiors that need to change configuration over time. The Acousti-Seal® Legacy® Electric operable wall applies the manufacturer's unitized 3-inch (76 mm) platform to a continuously hinged configuration: panels are linked into a single train and driven electrically across the opening, so the wall is deployed without staff moving or positioning panels by hand.
Electric operation
The system is activated by two keyed switches operated simultaneously, a control arrangement that requires the operator to remain in a fixed position with both hands occupied while the panels are in motion. For facilities where the partition is operated frequently and by different people, automated operation also makes the closing sequence repeatable, so acoustic performance does not depend on how carefully the wall was set up on a given day.
Panel construction and acoustics
Panels are unitized on a roll-formed and welded 16-gauge steel frame with steel faces, available at 52, 50 or 28 STC, with hanging weights between 6 and 11 lbs/sq.ft. depending on the rating specified. Sealing is by fixed sweep at the top and, at the bottom, an automatic A2 2-inch seal or a floating seal.
Dimensions and layout
Maximum height reaches 28 feet (8,534 mm) — taller than the manual paired panel configuration on the same platform — with track options #14 and #30. A single run covers up to 164'-11" (50,267 mm), and a paired arrangement closing from both sides of the opening covers up to 329'-7" (100,457 mm). Because a continuously hinged wall runs and stores as one unit, storage depth and the electrical service to the track should be resolved at an early stage of the project.
Circulation and finishes
Pass doors are available in a single leaf of matching construction. Panel faces can be specified in standard and premium fabric; standard, premium and heavy-duty vinyl; carpet; marker and tack board; plastic laminate; the client's own material; or uncovered.
