What is Drywall Partitions?
Drywall is a high performance light-
weight partition system consisting of
GI steel frame encased with gypsum
plaster boards on either side attached
through self drilling drywall screws.
The joints are then taped and finished
with gypsum jointing compound.

Different types of Drywall
1. Dry Lining Systems:
• Suited specially for lining of interior of exterior walls.
• Less or no background prepration like plasters is required as this system contains
adjustable brackets.
• Improved thermal, sound and fire insulation of masonry walls.
2. Interior Partition Systems:
• These systems basically used for partitioning in commercial offices (cabin to cabin).
• The thickness varies from 75mm to 100mm.
• Provide acoustics upto 45dB and passive fire protection from 30mins to 60 mins.
• Light weight partition (varies from 20kg/m to 30kg/m ).

• Flexible and easy to install.
• High Quality of interior finish.
3. Performance partition Systems:
• These systems are used for hotels, hospitals, residential, entertainment (cinema
wall) and industrial sector.
• High level of acoustics (50dB to 70dB) can be achieved.
• Provides passive fire protection (1hr to 4hr).
• Flexible and easy to install.
• High Quality of interior finish.
• Various types of loading (TV, Head Board, Heavy Fixtures) can be done.

Jointing and Finishing
Jointing & Finishing materials produce a smooth, continuous, crack-free lining surface ready for priming and
final decoration. A range of jointing specifications is available to suit the board type, method of application,
and site preference. The jointing process normally has three application stages - embedding the tape and bulk
filling the joint, secondary filling to take up the shrinkage, and finishing. Jointing materials provide durable joint
reinforcement and sealing which is a pre-requisite if the building element is to achieve its specified levels of fire
resistance and sound insulation.

Insulation
Insulation provides thermal and acoustic insulation for drywall partitions and is tested and recommended
for use in Gyproc India systems. This high quality roll and slab fulfill the specific performance criteria cost-
effectively. Their natural mineral base, very high percentage use of recycled material and lack of damaging
gases either in the products or their manufacturing process ensures excellent environmental credentials,
in addition to their energy-saving properties.
Insulation can be of two types:
• Glasswool - 20kg/m density
3
• Rockwool - 50kg/m density
