Cinema Liner Wall - GZZ  Series

Cinema Liner Wall - GZZ Series

System Description:

GZZ Series – 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 / bulkhead)

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

Component:

 

Gypsum Plaster board

High density fire rated plasterboard such as ; FW, MRFW, etc

Acoustic Head bracket

Used as sound isolation device between the roof and the Z-Z studs

Base Angles*

Horizontal member of Z-Z metal structure with 50mm minimum flange height.

Z-Z Studs*

Vertical member of Z-Z metal structure, consisting of a left and a right Z studs fixed together

Fasteners

Fire rated Anchors are used for fixing the base angles to the floor and the head bracket to the concrete super structure. Appropriated fasteners for other structures.

Hex Head screws

Used for fixing the Z stud together and for fixing the Z-Z stud assembly to the Base angle; available as self drilling

Drywall screws

Used for screw fixing the boards to the metal structures; available as self drilling

Joint tape and Filler

Used to get a even smooth and homogenous surface at the joints

Sealant

Applied at the perimeter areas, to achieve the necessary fire and acoustic performance

Insulation

Used as cavity infill to enhance sound insulation
