Drywall, also known as drylining, is a type of material typically used for the purposes of constructing walls and ceilings, as an alternative to plaster. It is made primarily of gypsum, which is a mined mineral. The name ‘drywall’ stems from the fact that the water used is in crystalline form, providing the finished product with fire resistant properties.

This is often preferable to plaster as it reduces the long drying time associated with its use, and walls and ceilings that may take weeks to plaster can be completed in several days using drywall.

Drywall is commonly used for wrapping columns to conceal steel beams and as a cost-effective way of topping off masonry walls above ceilings. Its fire-resistant characteristics mean that it is also used in walls and ceilings to contain the spread of fire. It is both quick and easy to install, is very durable and can be maintained much more easily than plastered walls.

* Tapered edge: The long edges of the board are tapered at the front with a wide bevel.
* Plain edge: The whole surface has a thin coating of finishing plaster.
* Beveled on all sides: All four sides of the board are bevelled. Commonly used for roof construction.

Specialised forms of drywall can be manufactured, such as:

Panels are fixed to metal studs vertically, but best fixed to timber studs horizontally since timber is more likely to warp over time, and horizontally hanging (along with a drywall adhesive) helps minimise deflection. Fixing techniques include wallboard nails and screws using a screw gun. Typically, screws are placed about every 4 inches.

The finishing process involves hiding the joints between panels using wallboard joint tape and a joint compound spread along each seam using a finishing knife. Once the compound has set and dried out, it should be lightly sanded using sandpaper until no tape is visible on the surface and it is smooth and flush with the rest of the wall.

Drywall ceiling installation requires thinner sheets than walls, as they are not as heavy which makes them easier to install. When installing, the walls should be built in first to enable extra support for the ceiling.
