• A gypsum board system is known as a gypsum drywall, and is used for constructing false ceilings as well as internal partition walls.
• Gypsum is a natural mineral which is converted into plasterboard and then sandwiched between thick sheets of paper on both sides.
• The gypsum boards are used for fabricating drywalls and are available in various dimensions. These boards are usually 2–4 feet wide and 6–15 feet long, and are available in various thicknesses.

What are the strengths of gypsum drywall construction?

• A gypsum drywall is very light in comparison to traditional brick masonry and hence reduces the load on the structure of the building.
• A gypsum drywall is faster to install because it is not a labour-intensive job and does not require curing. Note that brick walls are labour-intensive, need to be finished with plaster and require adequate curing time before finishing the surface with wall paint.
• The gypsum drywall can be easily finished with paint or wallpaper.
• It is a very good acoustic material that prevents the transmission of sound from one room to another.
• The material is recyclable and eco-friendly.
• Gypsum drywalls have high resistance to fire.

What are the shortcomings of drywall construction?

• Gypsum drywalls cannot be used for exterior walls as they cannot withstand external weather conditions such as heavy rain and winds.
• These walls are not resistant to moisture, so they should not be used as the internal walls of bathrooms. They are prone to damage caused by water and become a breeding ground for mould and mildew.
• Gypsum drywalls cannot be used to construct a curved internal wall as it is not a flexible material.
• Unlike brick masonry construction, the joint lines of adjoining boards may be visible in gypsum drywalls.
• These walls are not as strong as brick.

When should I opt for a gypsum drywall for constructing an internal partition?
All residences are constructed with internal brick masonry walls. In case you are renovating an existing home and want to change the room sizes by introducing a new partition, then it is advisable to go for gypsum drywalls. This is because it is a faster, cleaner and more efficient mode of construction.

How is a gypsum drywall installed?
A gypsum drywall comprises a supporting GI steel frame encased within gypsum plasterboard on both sides. The gypsum plasterboards are attached to each other on either side with fasteners such as nails and screws.

For good acoustics and thermal insulation, the gap between the gypsum boards can be filled with insulating materials such as glass wool.
