Dry Wall Partition & Wall Lining
Drywall is a high performance light weight partition system consisting of GI steel frame, encased with gypsum plasteroards on either side attached through self-drilling drywall screws. The Joints are then taped and finished with gypsum jointing Compound.
Drywalls can be used to partition any interior and are the preferred choice of construction for a range of applications, in homes, hotels, hospitals, schools, theatres, and industry. They are strong and robust (drywalls of up to 15 metres high have been built) and can typically last the lifetime of a building unless they are subjected to abuse or alteration.
Benefits of Drywall
1. Dry Construction : Consumes 95% less water than masonry construction.
2. Speed of Installaton : 3 to 4 times faster than masonry construction.
3. Light Weight : 8 to 10 times lighter than masonry system.
4. Flexibility : In creating and dividing spaces according to your needs.
5. Aesthetic Appeal : Seamless and crack free surfaces
6. Excellent Performance : (a) Acoustic comfort, (b) Fire safety, (c) Thermal comfort:
7. Environment Friendly

Different types of Drywall
1. Dry Lining Systems
2. Interior Partition Systems
3. Performance Partition Systems
4. Wet Area Drywalls
The Drywall type can be decided based on the following
KEY DESIGN CRITERIA.
a) Height of the Wall – While a normal Drywall classic solution can be built for heights upto 2.5meters, customized Drywall solutions can be built for walls upto a height of 17 meters.
b) Fire rating required – Fire rating criteria is usually governed by the National Building code. The fire rating is broken up into 3 parts viz. stability, integrity and insulation. Rating from 30 mins to 4hrs can be achieved with different partition systems.
c) Duty Rating Required – All Drywall partition systems have dury rating as defined under BS 5234 part 2. The duty rating may vary from light to medium to heavy to severe. This rating relates to the strength and robustness characteristic of partition system against specific end use.
d) Acoustic Requirement – The acoustic requirements of Drywall System is measured in terms of STC or RW. Heigher the STC/Rw values, The Higher will be the sould insulation of the Drywall.
Acoustics [Rw] as per ISO 140-3 – from 36 to 70 can be achieved with varying systems.
e) Moisture – The Drywall system varies with the level of moisture present in the application area. For wet areas, Moisture Resistant MR Fibre boards are preferred.
