1. Wall and Ceiling Construction: It's widely used for constructing interior walls and ceilings in both residential and commercial buildings.

2. Partition Walls: Ideal for creating partition walls to divide spaces without permanent alterations.

3. Soundproofing: Special types of plasterboard can help in soundproofing rooms, making them quieter.

4. Fire Resistance: Fire-resistant plasterboard is used in areas that require enhanced safety measures.

5. Decoration: It provides a smooth surface for painting, wallpapering, or other decorative finishes.

6. Renovation Projects: Often used for renovating older buildings to provide a fresh and updated look.

It’s also relatively easy to install and cut, making it a favorite for DIY projects.
