Not required — all systems are top-hung. No floor track on any MODUWALL system.
Motorized and Ultra-High are configurations of the same NW840-W platform; the steel frame is what makes 59 ft possible.
Test values apply to the specimen described above, tested at a 4 000 × 2 500 mm opening. Sound insulation in the finished installation depends on the surrounding structure, the head detail and the sealing of the perimeter.
