Drywall construction is a common method used in modern construction due to its efficiency, cost-effectiveness, and ease of installation compared to traditional plaster walls. **

They are installed by attaching them to the wall or ceiling studs using screws, and then the seams between the boards are covered with joint compound and tape to create a smooth surface. Plasterboards are also used to provide fire resistance, sound insulation, and to create a smooth and even surface for painting or wallpapering. Overall, plasterboards are essential for creating durable and aesthetically pleasing interior spaces in drywall construction. **

In drywall construction, it is generally recommended to install the ceiling first before the walls. This is because it allows for a more seamless and secure installation of the ceiling drywall without any obstructions from the walls. Additionally, installing the ceiling first can help to provide better support for the walls and ensure a more even and level finish. However, the specific order of installation may vary depending on the specific requirements of the project and the preferences of the contractor. **

Yes, it is possible to install drywall before renovation plastering. Drywall can be used as a base material for plastering, providing a smooth and even surface for the plaster to adhere to. However, it is important to ensure that the drywall is properly installed and secured before applying plaster to avoid any issues with the final finish. Additionally, it is recommended to consult with a professional contractor to determine the best sequence of steps for your specific renovation project. **

OSB (oriented strand board) boards are commonly used in drywall construction as a sheathing material. They are typically installed over the wall studs to provide a solid base for attaching drywall. OSB boards help to strengthen the structure, improve insulation, and create a smooth surface for the drywall to be installed on. Additionally, they can also help with soundproofing and fire resistance in the building. **
