Weedon Posted January 2, 2008 Share Posted January 2, 2008 10 things you should know about plasterboard1Plasterboard is basically an inner layer of gypsum sandwiched between two outer layers of lining paper including various additives in the gypsum layer and varying the weight and strength of the lining paper, will give the finished board different properties2Gypsum is made up of crystals containing a small amount of water (known as water of crystallisation). In a fire, this water is driven-off, helping to keep the temperature of the fire down, and preventing rapid fire spread. Plasterboards, such as Gyproc FireLine, are therefore used extensively for fire protection proving up to 4 hours protection in some special multi-layer system applications.3Plasterboard is good for cutting down noise transmission particularly airborne sounds such as speech and music. High performance plasterboards, such as Gyproc SoundBloc, have a specially designed core that provides even better insulation against sound.4Whilst standard plasterboard is ideal for most environments, it shouldn't be used in constantly damp conditions. For kitchens, bathrooms and similar damp areas, Gyproc Moisture Resistant should be used. It's specially designed with silicone additives in the core so it just shrugs off water it's great as a tile backer.5Glasroc MultiBoard, a glass-fibre reinforced gypsum board, is not made in the traditional way with lining paper . Instead, the boards are strengthened with layers of glass fibre immediately below each surface. This gives them good all-round performance, a high quality durable plaster finish, and enables them to be easily bent for use on curved structures. They are excellent for semi-exposed areas, such as soffits and the like.6Most 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.7Plasterboard 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 the British Gypsum GypWall RAPID metal stud housing partition system and 600mm sheets for use where space is limited.8Most standard plasterboard has one ivory face and one brown. The liner on the ivory face is specially designed for plastering plaster should not be applied to the brown reverse face. Paper liners are generally made from recycled paper a big plus for the environment.9Joint cracking on plasterboard ceilings is almost invariably caused by warping of the joists as the wood dries out. Screw fixing the boards will generally prevent the problem occurring. If you want to go further use the British Gypsum SureLyner system, designed to upgrade ceilings to Part E acoustic standards, which will virtually eliminate the chance of movement problems.10Although you can apply wallpaper directly to the paper surface of plasterboard, ideally the surface should first be sealed with one coat of Gyproc DryWall Sealer to allow easy stripping at a later date.

Anton Redman Posted January 2, 2008 Share Posted January 2, 2008 Confused I am :French plasterboard normally grey side out with he indented edges ready for taping and filling. The other side of French plaster board is normally a grotty sort of brown colourUK plasterboard which has a white /ivory face depends if you are goint to skim it. If so grey side out. If you intend to paint straight over then white side out.

stewart Posted January 2, 2008 Share Posted January 2, 2008 Are the French plasterboards any different? British gypsum plasterboards should only be skimmed on the ivory face. Link to comment Share on other sites More sharing options...
Nick Trollope Posted January 2, 2008 Share Posted January 2, 2008 Given that this is a French forum; French plasterboard should only be used with the "white" (tapered) side out. You will not find much (if any) straight-edged board here. This surface will take most things, if treated appropriately first (sous-couche for paint, etc). I've only seen placo skimmed once and the plasterer (an incompetent Brit) didn't treat the board with anything.Apart from standard (white) board you will find green (hydrofuge) water resistant baord and (again, rarely) red firestop board. Available in 1200 or 600mm widths, tapered both long sides and 2500mm long. BA13 is 13mm thick, if you search/special order you will find 10mm board. If you want it thicker, double up!I've never come across a noise-stop board (apart from those with rockwool glued to the back). Link to comment Share on other sites More sharing options...
Anton Redman Posted January 3, 2008 Share Posted January 3, 2008 2600mm , 2800mm and 3000mm are also available in Builders Merchents. Link to comment Share on other sites More sharing options...
