Drywall as a ceiling
The basis of GKL are conventional gypsum and paper board, made up in a uniform homogeneous sheet with standard sizes for most manufacturers. The structure of the material is "sandwich".Sheet gypsum is located between the cardboard layers.
Multi-ply board has high strength characteristics with good thermal insulation. If you need to perform a quick repair of the ceiling with gypsum board, the versatility of its properties allows you to use various frame and frameless methods of performing the work. Separately, one must say about the hygiene and harmlessness of GCR for human health.
To increase the resistance to moisture, cardboard can be impregnated with special water-repellent additives. Such methods, provided additional protection measures, allow the installation of plasterboard on the ceiling in rooms with operating modes of high humidity.
When making sheets in gypsum dough special additives and fibers are placed. This creates the reinforcement effect and slightly increases the overall strength of this sheet material. At the same time, GKL is easily amenable to all possible processing methods( sawing, cutting with a knife), they can be given almost any form, combined in different combinations with other materials.
Multi-level finish of the ceiling with plasterboard, with the use of various luminaires and entire lighting systems, is capable of transforming the most common room beyond recognition. Special "arched" views of the GKL make it possible to finish the openings in the form of arches, which have again become very popular in the design of premises.
The main characteristics of the GKL in the finish
Speaking about the merits of the material as a whole, we can say about the need for additional measures to protect the base from the sheets from exposure to moisture. Gypsum is hygroscopic, easily absorbs and gives moisture, so installing a ceiling gypsum board and applying it in the finish, in addition to directly protecting the surfaces from water, requires additional ventilation.
The structure should be ventilated, "breathe", giving off excess moisture. However, in certain cases, the ability to accumulate moisture and curl in the wet state is rather a virtue. Such techniques are used in the formation of arched finish sheets.
Along with the ease of processing, with a low height of the premises and under the condition of flat surfaces, fixing the plasterboard to the ceiling can be done without the use of frame structures, directly on the base with special mastic glue compositions.
This ensures a reliable and smooth surface, ready for final qualitative finishing. The cardboard base of the new surface allows to apply almost all types of such finishes.
But more often the device of a ceiling from gipsokartona assumes use of special frame systems. The material of their manufacture can serve as a wooden bar or rake. The main condition is the rigidity and strength of the base. The most universal and convenient to use are systems of metal bearing profiles.
Presence of all necessary elements, ease of their joining, processing by the sizes, allows to collect skeletons of the most different degree of complexity. In fact, sheets and profile sets make up complete systems for gypsum board finishing. In the end, using a ceiling profile for drywall, you provide significant savings. Sets of profiles are responsible for the strength, withstanding the weight of the skin, luminaires, other attachments.
In fact, the GKL ceiling is hanging, and very often in the sub-ceiling space are placed different communications. Therefore, the cold-rolled sections have a box-shaped shape with three ribs to the side, bumps for reliable fastening( often as a latch type), perforation for fasteners and communication lines.
In addition, the kits are supplemented by reliable suspension brackets and adjustable suspensions with snaps, extensions, connectors, etc. All types of profiles are easily cut and drilled, interchangeable, their size makes it easy, having formed a typical frame structure, how to make a ceiling from gypsum board, andGKL for walls and partitions.
The main rules for mounting the gypsum board
There are profiles guides, rack and carrier( easily inserted into the rails).To work with such sets of wireframe elements, you will need scissors for metal, tape measure, ruler, square, screwdriver with attachments( it is important that the direction of rotation of its head is switched).It is more convenient to use the battery version of the instrument.
If you have already decided to install a ceiling from gypsum board, how to do this operation will prompt our article. So, the work on the device is conducted in several stages. First prepare to markup. The walls and ceiling are cleaned and, if necessary, reinforced with putty. For the marking of the wall profiles of the frame, the building level( better than the water one) is used, the bale cord, roulette( length should provide the possibility of measuring without intermediate marks), plumb bob, meter( folding or measuring tape), construction square, marker.
The line of fixing the wall profile is broken off. Its fixing along the perimeter of the room is carried out on the dowels using a perforator or an electric drill with the corresponding function. The mounting step depends on the load( standard - 0.6 m).
During the selection of the selected frame structure, the profiles are fastened to self-tapping screws - "fleas" or "bugs". The sheet fastening is carried out with a screwdriver with a restrictive nozzle, which prevents damage to the cardboard layer. The screw head should go level with the surface.
The length of the hardware must provide a depth of fasteners not less than a centimeter. The fixing step is no more than 0.25 m( 0.2 m on the average).In general, the required number and types of fasteners are calculated according to the size of the room, the number of brackets( 4 screws per each), the number of layers of sheets, observe the obligatory condition for alternating joints.
