Chase Wall Partition - GH  Series

Chase Wall Partition - GH Series

System Description:

GH Series – used for very high acoustic partitions, comprises of multiple layers of gypsum boards screw fixed on the outer side of the UC structure having parallel row of tracks and studs. The parallel rows of studs are braced by plasterboards or by metal profiles or by metal profiles through Acoustic V-brace, at defined horizontal heights for various acoustic performance requirements. Filling each stud cavity 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.


  • Fire protection – up to 3 hrs
  • Sound Insulation – up to 72 dB


Gypsum Plaster board

Based on the performance requirement, the plasterboard needs to be selected – RG for general applications; MR for humid and aerated area application; FW for enhanced fire resistance; TF for enhanced Impact resistance etc.


Horizontal member of UC metal structure with equal 32mm minimum flange heights. In case of deflection the Top tracks have a flange height of minimum 50mm


Vertical member of UC metal structure with unequal flange heights( suitable for boxing of studs)


Used for fixing the tracks to the slabs and floor respectively

Drywall screws

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

Joint tape and Filler

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


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


Used as cavity infill to enhance sound insulation

Fixing channel

Used as backing for horizontal edge cut joints in fire rated partitions

Bridging component

Plasterboard, Fixing channel and Acoustic V-Brace

 * Stud spacing and metal thickness will be determined by the partition height, deflection limit and lateral pressure. Min. recommended metal thickness is 0.55mm for fire rated partitions.
