PLASTERBOARDS Plasterboard is a rigid flat sheet material which comprises of a core of gypsum plaster with the surfaces covered by stout paper. This covering paper gives flexibility and durability to the plasterboard.

Plasterboards can be used to obtain self finished wall surfaces ready either for direct decoration or for a single final coat of plaster. Also, plasterboards can be used to obtain partition walls and to form ceilings.

ADVANTAGES OF PLASTERBOARDS Its lightness workability Speed of application It is demountable It has easy application details It forms suitable base for most kind of finishing layer It is fire resistant Thermal insulation

DISADVANTAGES OF PLASTERBOARDS Plaster finishes applied to them may crack due to vibrator or movement in the joints which they’re fixed. They are poor sound insulator.

TYPES OF PLASTERBOARDS GYPSUM BASEBOARDS They are specifically made as a base for one or two coats of gypsum plaster and are enclosed with coarse textured paper to provide a good key. it is less likely to crack and provides greater protection against damage by fire. Joints should be scrimmed and reinforced with jute scrim. Boards have square edges.

GYPSUM LATH Lath provides backing and adhesion for gypsum plaster. For better insulation gypsum lath is sometimes made with a sheet of aluminium foil attached to the back. Because of the rounded edges, joints do not require to be scrimmed. Lath measuring are usually 406x1200x95 mm.

GYPSUM WALLBOARD Plasterboard designed for direct decoration, suitable for internal partitions and ceilings. Available with square edges and bevelled edges. Wallboard measuring are usually 600x2400x95 mm.

Classification of Plasteboards According to Their Gypsum Properties (in Turkey) White Plasterboards Its core is formed from gypsum which gives lightness, hardness, durability and good workability to the plasterboard.

Green Plasterboards Its core gypsum material are strengthen against the water and damp. So it can be used in wet spaces as a water resistant material.

Red Plasterboards Its core gypsum material are strengthen against the fire with organic fibers and other additives. So it can be used in spaces which fire resistant materials are required.

APPLICATION Normally they are applied to timber battens or metal channels attached to the wall at centers to suit the spanning properties and module size of board. The boards should be nailed to studs with 32 mm galvanized nails. A space of about mm should be left between boards.

The joints should be filled with gypsum plaster stopping. Joints must be covered with 100 mm wide joint tape, in order to prevent cracks. Finishing can be a direct application of paint, varnish or wallpaper; but the joints must be masked carefully. Alternatively, the joints maybe made a feature of the design by the use of edge chamfers or by using moulded cover fields.

Technical Properties of the Boards Lenght:2500 mm ( mm) Width:1200 mm ( mm) Thickness:12,5 mm (6-9, mm) Average Weight: ≤ 9 kg/m 2 ( kg/ m 2 ) Spacing Between The Studs: 600 mm (400 mm)
