The “Full Acoustic Roll Up” has been engineered to be the best performing roll up curtain achieving acoustic values up to 33db. Two continuous independent vinyl panels meet the floor to form a positive sound seal. Panels have a continuous tie at mid height isolating the central anodized aluminum extrusion from transmitting sound from one side to the other.
Curtain rolls up to 610mm (24”) of overhead which is superior to conventional fold up double wall that fold to 1270mm(50”) with similar sound transmission and savings in cost, makes this curtain a best buy for an acoustic barrier.
Supplied with valences and alcoves as a requirement for safety and acoustic benefits, this curtain must be installed with the full height panels extending wall to wall.
The system includes a 2hp, 3-phase tubular motor installed in one end of a custom anodized 110 mm (4 1/2") aluminum extrusion at half curtain height. The motor is thermally protected and contains an electric brake, planetary gear system and limit switches. Motor control is by electric contactors operated by a spring-loaded key switch.
The curtain is supplied complete with valences and alcoves to completely seal off the gym when the curtain is down. The small 152mm (6”) space between curtain edges and the walls almost totally eliminates sound transmission, when installed with valences and alcoves. The roll up design reduces stress points and the curtain remains flat and crease free. This curtain model has the added feature of absolutely no exposed hardware. The curtain rises to within 610mm (24”) of overhead and is not suitable where the ends of the curtain is exposed.
When energized, the motor and center aluminum extrusion rotates, this results in the tube winding up the lower portion of the curtain panels as it rolls itself up the upper portion of the curtain. The torque reaction of the motor is transmitted via a car system that is contained in a flexible track mechanism mounted to the wall in line with the curtain from half height up to the overhead. The curtain rolls flat with no highly stressed areas and the operation is barely audible.
Operation is by a spring-loaded key switch, which is directly accessible and contained in a supplied, all steel enclosure. The electrical supply is 208 Volt 20 Amp single phase and is permanently connected by others. Some curtains may require a secondary synchronized motor where the size dictates.
The curtain consists of two panels that cover the full opening and is of an all vinyl composition. The vinyl is 1.1 kg/m² (32 oz/sq.yd.) vinyl coated polyester, with similar appearance and embossed on both sides, resistant to staph, rot and mildew. The vinyl meets or exceeds the California Fire Marshall and NFPA standards for flame resistance. A label from a qualified testing laboratory, certifying flame resistance and smoke rating of the curtain shall be attached to the bottom of the curtain.
The top edge of the curtain is a pocket that contains a 40.6 mm (1.6”) diameter pipe for mounting directly to a beam. At mid height of the panels, a 4.74mm(3/16”) diameter cable is sewn enclosed into the vinyl to fit and hold the curtain sections in the groove of the lightweight aluminum drive tube.
