Shaftwall - GSW Series

Shaftwall - GSW Series

System Description:

Gypsemna Ceiling solutions – comprising of a grid of completely concealed suspended metal frames (void of wire hangers and wire-clips) lined with gypsum plasterboards with its joints, treated (taped and filled) to achieve the even, smooth and homogenous surface – to receive paint or further decoration.

  • Light weight and versatile
    • Supports in concealing cableways, ducts etc
  • Quick and Easy to install
    • Cost effective
    • Reduced Project completion time
  • Performance
    • Fire protection – up to 2 hrs
    • Sound Insulation – up to 70 dB (when used under a concrete floor)
    • Enhancement of fire & acoustic performance can be achieved by increasing the number of layers of plasterboards
    • Filling the cavity with insulation on the back of the ceiling enhances of acoustic performance
GC Series– Suspended concealed system with Single or multiple layer Gypsum plaster boards, suitable for fire rated and non-fire rated ceiling systems.


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; etc.

Perimeter support

Wall angle fixed at the perimeter on which Furring channel at 90°is supported. The plasterboard is screw fixed to its underside.

Primary Carrying Channel

Main Channel (MC) - Horizontal member at max. 1200mm* centres, with 38mm minimum web width.

MC- Suspensions

Vertical member of variable length- identical to the Main Channel, screw fixed to the Main channel at max. 1200mm* intervals.

Secondary Carrying Channel

Hat shaped Furring channel running cross-wise and screw fixed to the Main Channel at max. 600mm* centres


Used for fixing the MC-suspensions to the slabs and wall angles to the wall respectively at max. 600mm centres

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 quilt covering the entire ceiling system will increase sound insulation in the void. Rockwool slabs are used to enhance the fire insulation.


* Main and Furring channel centres, MC-suspension interval will be determined while designing the system. Min. recommended metal thickness is 0.55mm.
