CEMENT BOARD (OR DRYWALL)
Cement board (also called drywall, plasterboard, dry lining, wallboard, sheetrock, gypsum board, and more) is a panel made of calcium sulfate dihydrate (gypsum), with or without additives, typically extruded between thick sheets of facer and backer paper, used in the construction of interior walls and ceilings. The plaster is mixed with fiber (typically paper, glass wool, or a combination of these materials); plasticizer, foaming agent; and additives that can reduce mildew, flammability, and water absorption.
Cement board It is made in 10 mm, 13 mm, and 16 mm, and sometimes other thicknesses up to 25 mm. Panels are commonly made in 1200 × 2400 mm, 1200 × 4800 mm, and 1200 × 6000 mm sheets. We normally use a 16 mm thick cement board with a size of 1200 x 2400 mm. The sheets are secured to a timber frame made of 40 x 60 mm beams anywhere from 150 to 300 mm centers along the beam and 400 to 600 mm across members.
The drywall is then fixed to the structure with nails or drywall screws and/or glue. Drywall fasteners, or drywall clips or stops, are gaining popularity in residential and commercial construction. When driven fully home, drywall screws countersink their heads slightly into the drywall.

♠ Sound reducing,
♠ Easy repair,
♠ Fire resistant,
♠ Many finishing options.
The disadvantages of using cement board:
♠ Not water resistant, and when damaged needs to be replaced,
♠ A damp cement board will allow mold to develop,
♠ Not resistant to impact and easily damaged.
The cons of drywall are fixable problems. Minor problems from the expected wear and tear are easily manageable. The advantages of drywall are plenty and give you a good reason for investing in this material.
