A plasterboard ceiling may sag due to several factors, including excessive moisture, which can weaken the material, or inadequate support during installation. Overloading the ceiling with heavy fixtures or improper spacing of support joists can also contribute to sagging. Additionally, temperature fluctuations may cause materials to expand and contract, leading to structural issues. Regular maintenance and addressing any water leaks can help prevent such problems.
The advantages of installing a plasterboard ceiling in a residential property include easy installation, smooth finish, sound insulation, fire resistance, and the ability to conceal wiring and pipes.
As he laid down in the hammock, it sagged in the middle.
Cracks can develop for numerous reasons, the most common is ceiling cracks. This is generally because there is movement in the joists which the plasterboard is attached to.

Apply a second coat of compound if needed, and sand again once dry. Prime and paint the repaired area to match the rest of the ceiling.
The recommended size of plasterboard screws for securing plasterboard to wooden studs is typically 1-1/4 inch to 1-5/8 inch in length. It is important to use coarse-threaded screws specifically designed for plasterboard installation to ensure a secure and stable attachment.
Use GRP board - it bends. Set the plane the board is to follow by constructing a timber frame. Screw the Board to the frame. Voila. Finish as usual. If you can't get GRP - (made by British Gypsum and others) you can cut the plasterboard into strips and make a multifaceted facsimile of a curve and then plaster over the board to form a smooth line.
Asbestos was commonly used as a component in building materials, including plasterboard, before its harmful health effects were well known. However, most modern plasterboard does not contain asbestos due to safety concerns. It's important to check with a professional if you suspect that your plasterboard contains asbestos.
Plasterboard is a good insulator because it contains trapped air pockets within the gypsum material, which helps to reduce heat transfer. The thickness of the plasterboard also provides an added barrier to heat flow. Additionally, plasterboard has a low thermal conductivity, further aiding in its insulating properties.
Asbestos is no longer used in plasterboard.At one time it was used in the paper on the outer surface of some plasterboard, or in the spackling compound that was used to conceal the joints between two installed pieces of plasterboard.
