Lightweight and durable drywall is used for many kinds of finishing: they can coat the walls of it, you can create partitions, build ceilings.
For any work with this material, you must create a framework of special profiles, which are attached lists.
Profiles for gypsum boards arefixing and guide elements which serve for the frame structure. Typically, the profiles are manufactured from metal, most frequently made of galvanized steel - durable and lightweight material. To manage the work with plasterboard without profiles can, if need be lined wall - simply glue the sheets to the surface, but in this case the quality of work is poor, because the guides allow to achieve a perfectly flat surface, attach the design rigidity.
Types of profiles for plasterboard
There are several different types of profilesdrywall, their diversity, and various applications can confuse beginners. For major works with this material is enough to have an idea of a few main types of profiles. This guides the standard frame depth of 40 millimeters and a width varying from 50 to 100 millimeters. They can be used for different types of work, including finishing of walls or ceiling.
There are special ceiling railsDevice intended for the construction of suspended ceilings. These enclosed ceiling profiles, they can be secured by anchors or direct hangers to the ceiling and create a finished frame for attaching drywall. For walls and create partitions using plasterboard wall or rack-mount profiles, which are fixed to the guide rails. The price of these elements depends on the width and the material from which they are made.
Corner profiles serve for alignment angles, the flashing - alignment walls.
The metal frame is attached to a wall or othersurface by means of special fastening elements. The most frequently used plugs of plastics or metal. You can use direct hangers, they are installed on marked lines with a pitch of about 60 cm. It also can be Connectors "crab", anchor clips, duplex connectors, self-tapping screws, wood screws. Selection of an appropriate fixture will depend on operation - for example, when the device is used to flatten the ceiling connectors such as "crab", they allow setting sheets of the same level.
If the ceiling has a length of more than four meters, it is necessary to use an extension cord.
Sometimes, instead of fastening elementsProfile segments are used the same guide, their bent-shaped "T" and fixed to wall anchors, and by means of screws which are screwed on the frame. Skilled craftsmen say it is the most rigid structure.
