Plasterboard is a building material that comprises a sheet of gypsum compressed between two sheets of strong paper.

Plasterboard is now the preferred method of preparing a wall for a skim finish. It is cheaper than backing coats of plaster in terms of time and materials and has better heat and sound insulation properties.

Plasterboard comes in a range of sizes and types to suit many building application.

Plasterboard is typically 9.5mm or 12mm thick in its standard form. Sizes include

1200 x 900 mm known as base board.

1800 x 900 mm

2400 x 1200 mm

Specialist plasterboard types include

Aquaboard for wet areas such as showers that are to be tiled.

Fireline where enhanced fire protection is required.

Moisture Barrier in areas of condensation such as window bays.

Insulation board where foam is bonded to the board to increase the heat insulation properties of a project.

Soundboard enhancing the acoustic and sound insulation properties of a surface.

Cutting Plasterboard

When applying plasterboard to a stud wall it will usually be measured and cut to joist or noggin centres.

A full width of plasterboard can be scored with a blade knife creating a straight point of weakness. Pressure applied to the back of that line will cause the board to break along the desired line.

When cutting pieces of board less that 1cm wide we suggest that the plasterboard is scored on both sides

To cut part way into a board use a combination of a pad saw and then the blade knife.

To shape the edge of board use a small rasp or surf form to shave off small amounts of board.
