Knauf Cinema Systems
Knauf KWC A116 is a high performing, cost effective wall system designed to meet the high requirements of sound reduction and fire resistance for modern day cinemas.
The Knauf KWC A116 Cinema system is a V-braced double-stud system installed full height between floor and soffit structure providing excellent acoustic performance as well as fire protection up to 3 hours.
The wall, not less than 450mm footprint to reach Cinema sound reduction requirements, consists of two rows of parallel vertical 3 1/2â€ť (89 mm) CW-profiles spaced at max. 24â€ť (610 mm) centres, each one braced by V-braces extended to a UW runner at 2m vertical centres from one row to the other for heights up to 15m. The CW-profiles are braced between UW 89mm floor track and deep flange head tracks that are fastened to the primary supporting structure. 3 layers of Knauf 5/8â€ś (15.9 mm) Type X gypsum boards are screw-fixed horizontally to the external sides of the double stud frame with both horizontal and vertical joints staggered from layer to layer.
Sealing of all junctions between the facing boards and the primary structures are kept flexible with Knauf Approved fire and acoustic sealant providing the necessary air-tightness in case of fire. A 3 1/2â€ť (89 mm) un-faced glass-fibre blanket of 16kg/m3 density is placed between the studs of each row preventing reverberation inside the void.
