Timber & Other Products - Sheet Materials - Plasterboard

Plasterboard is basically an inner layer of gypsum sandwiched between two outer layers of lining paper including various additives in the gypsum layer. It is often referred to as drywall.

Varying the weight and strength of the lining paper, will give the finished board different properties.

There are a number of types of plasterboard, each with its own characteristics which makes it most suited to particular uses :-

Basic board - is the 'common' type and is used to line ceilings, stud partitioning and is also used in dry lining. It is made up of a layer of hardened gypsum plaster between two layers of paper;
Insulated board - is similar to common plasterboard but incorporates a layer of insulating foam to the rear side to improve its thermal insulation;

Damp proof board - is similar to common plasterboard but incorporates a damp proof membrane on the rear face, usually a coloured silver foil;
Moisture resistant board - is different as the actual gypsum plaster is resistant to moisture and is recommended for use in areas where it could come into contact with water (although not immersed in it) - i.e. bathrooms, showers, kitchens etc.;
Sound insulation board - is used to reduce the transmission of noise;
Fire resistant board - offers increased resistant to fire, the other types of plasterboard do offer some degree of fire barrier but fire resistant board gives much better resistance.

Most common plasterboards come with the option of either tapered edge or square edge. Tapered edge boards are ideal for either jointing or skimming, while square edge is generally used for textured finishes.

Plasterboard generally comes in 1200mm wide sheets, designed to suit the standard 600mm stud spacing used in housing today. Other widths are available for specific systems for instance 900mm widths for a metal stud housing partition system, and 600mm sheets for use where space is limited.

Most plasterboards have a white paper finish on one side with the other side being a grey, thicker paper (or one ivory face and one brown face). The white paper side, the front face, is the finished side for decorating and it will accept a plaster skim or other finishes - the grey side is not suitable for any type of finish. When used in modern dry lining techniques, the front face is often not given a plaster skim. Wallpaper can be applied directly to the front surface, but this will cause a problem when the wallpaper needs to be removed for redecoration. It is recommended that dry wall primer is used prior to putting wallpaper directly onto new plasterboard.

Our plasterboard sheets are manufactured from the highest quality gypsum and with the use of special additives provide a range of high performance boards suited to acoustic, impact, fire-resisting and moisture resisting applications.

All of our products comply with current British Standards. They are supplied in different sheet sizes for a variety of purposes which are shown as follows :-

Standard Board Square Edge – 9.5mm x 2400 x 1200; 12.5mm x 2400 x 1200; 15mm x 2400 x 1200; 12.5mm x 1800 x 900; Standard Board Tapered Edge – 12.5mm x 2400 x 1200.

These boards can be used for installation with stud partitions, lining and ceiling systems.

Plank Board – 19mm x 2400 x 600. Can be used for drylining of walls, acoustic floors/ceilings and for stud partitions.
