Currently plasterboard partitions gained wide popularity and won the love of the builders, and ordinary consumers.The fact that this design has many advantages.Firstly, ready partition different smooth surface, which allows immediately after installation using different finishes: paint, wallpaper or other materials.Secondly, the plasterboard have good performance, in particular, they are vapor-permeable.This allows them to create the most optimal climate in the living room.Furthermore, partitions plasterboard is safe in a fire, because fire resistant enough.The ability to mount partitions of any configuration and is an undoubted advantage of this material.
Construction of the wall can be different.So, plating metal frame can be single or double-layer.Th
Talking about the device walls of plasterboard, determine their main elements.They are directly gypsum boards, metal frame of the profiles (rackmount, rails, corners) and insulating materials.
sheets of drywall - the ideal cladding metal frame ↑
Plasterboard sheets (FCL), often referred to as gypsum board or drywall.Their main purpose is the production of false ceilings, various types of partitions and walls.
structure of finishing material is quite simple: it consists of a core made of plaster and cardboard lining.The core is often made of plaster brand G-4, which is characterized by all the properties required for the construction and finishing works.FCL made on the basis of plaster, it helps absorb excess moisture from the air, and when it is insufficient - its release.Thus, the drywall can truly be considered a "breathable" material.
Ready gypsum core is coated linerboard.The qualitative adhesion of the two materials is done using special adhesive additives.Cardboard - a kind of skeleton sheet of drywall, which, among other things, is also a working surface for decorating.
Today there are several different versions of the GCR, each of which corresponds to the requirements in different environments.So you can select:
- gypsum plasterboard.This plasterboard is used in environments with high humidity.These lists are subject to special treatment different waterproofing compounds and preservatives.
- GKLO is ideal for spaces where relatively high risk of fire.In the manufacture of gypsum board used this specific additives that increase fire resistance.
- PCG - combined sheets of drywall.
basis of interior design - the metal frame ↑
basis drywall - is its metal frame.His installation made of several kinds of profiles, each of which has certain functional load.For the manufacture of profiles, generally used steel strip.Its thickness can vary from 0.55 mm to 0.8 mm.Profiles produced by cold rolling.
profile protection from the negative effects of the environment provides them with zinc.Normal air environment contributes to the formation of zinc carbonate on the surface of the profile.The zinc layer protects the profile against the spread of the oxidation process.The effectiveness of such a protective coating is caused by a fairly strong adhesion of zinc and steel.
Sure, metal frame must be strong enough to withstand not only its own weight but also the weight of sheets of drywall, the future of finishing material and possible external components, such as hours or paintings.To ensure a high degree of strength, profile helps ribs, taking place on the plane profile.Externally, they resemble the corrugations along.
profiles can be:
guiding profiles (PN) for plasterboard partitions ↑
Guide profiles are one of the main elements of a framework for the partition.They have a special section in the form of channel bars.The main purpose of these profiles is to provide a guiding framework for rack-mount counterparts.In addition, profiles of the guide may play the role of bridges located between rack-mount profiles.This need may arise, for example, when installing the door frame in the wall.
Each guide profile have special holes for dowels with which the frame is attached to the base.If desired, it can be further drilled hole.
Rack profiles ↑
Besides guiding profiles, plasterboard partitions requires a rack profiles (PS), which also have a cross-section like a sill.They are used to create a vertically disposed racks metal frame plasterboard partitions.These racks are designed to secure the sheets of drywall on them.
to central rack profile, which is called the "back" at an angle of 90˚ bends two shelves.Their width is 0.5 cm. It is worth noting that it is rated as a real its width is approximately 0.48 cm. Such a configuration profile ensures sufficient reliable and durable adhesion of two sections - the guide and the rack.This width shelves for accurate hit the screw in the hole.Of particular importance is the lining has a frame in two layers of drywall.
Furthermore, shelf rack profile characterized by the presence of longitudinal grooves usually in an amount of three pieces.Average groove is a kind of pointer places where are joined sheets of drywall.Side groove center the screws used.When installing metal partitions may be necessary to laying of various utilities.For these purposes, in the back of the profile, there are special holes.Typically, they are paired, and the diameter is about 33 mm.Install rack-mount profiles is carried out directly in the guide profiles.For the quality of their connections are often used screws.
Corner profiles for the device partition joints ↑
corner joints when installing partitions are sufficiently vulnerabilities.For their devices most commonly used gypsum boards with a straight edge.However, this solution has one drawback - is an increase in the likelihood that there will be mechanical damage to the partition during its direct use.In order to avoid such undesirable consequences it is accepted to use corner profiles (PU).
angular profile advantage is that it is sufficiently tight to the corner walls in 90˚.Coupling between the plasterboard panel and metal profiles by means of putty, which is available in a shelf filled the hole profile.If made of gypsum board surface is curved, then the arched profiles, bend radius which may vary.
Insulation drywall ↑
Often plasterboard partitions provide acoustic and thermal insulation.The most common for this insulating material is polystyrene, but it can become an alternative to mineral wool.
special Styrofoam popularity is due to its performance.The fact that it is different stable structure over a wide temperature range.It does not adversely affect various chemicals.In addition, polystyrene foam does not create a favorable environment for bacteria and fungi mold.
Thus, the partition of gypsum board includes a number of structural elements, each of which has its purpose.Knowledge of their characteristics allows one to properly approach the issue of resettlement partitions, to avoid the most common mistakes in installing it and get high quality results.
