Cinema Uner Wall
System Description:
Used in very high acoustic demanding applications. High acoustic insulation is obtained
by wrapping the cinema hall with an individual cinema wall liner comprising of multiple
(upto 4) layers of gypsum boards screw fixed on the open side of the counterbalanced
z-z stud structure fixed between the acoustic head bracket at the top and to the base
angles at the bottom. Adjacent cinema halls with common wall, shall be considers as
two back to back liner walls without any connection between them. Filling the stud
cavity of each liner wall with acoustic insulation blanket, will enhance acoustical
insulation as will do the sealing of the perimeters with Fire and Acoustic sealant that is
at the same time providing the necessary air-tightness in case of fire.
Advantages
· Light weight (in comparison to concrete / block-work)
· No need for structural reinforcements nor bracings
· Dry & high-speed installation
· "Easily understood" junctions with different structures
· Not only provides high acoustic performance also provides high resistance to fire
Performance
Fire protection - up to 2 hrs.
Sound Insulation - up to 75 dB( with sound stop ceiling I bull<head)
Applications
· Cinemas - in particular Multiplex Cinemas - Heights up to 15 m
· Auditoriums (Operas, Concert Halls, Universities)-up to 12 m
· Hotels (Halls, Ballrooms, Technical Floors)-up to 10 m
