Still, I wonder what professional builders and designers follow in their daily practice, giving preference to this popular material today.

Some examples of how to use drywall in construction are shown in the photo below.

Classification

Drywall is a plate having a gypsum core, framed on both sides with sheets of facing paperboard.

Gypsum base GKL includes various additives, giving the obtained material certain useful properties. By the type and purpose of the additives present in the feedstock, the drywall is usually divided into the following categories:

5

  1. GCR is the most common drywall, generally without additives. Its purpose is to cover the wall structures and ceilings in buildings with permissible temperatures and a low moisture content in the air.
  2. GKLO - fireproof gypsum board with reinforcing inclusions. This type of material is designed to erect structures in places where special attention is paid to fire safety.
  3. GKLV - a type of drywall that does not lend itself to the harmful effects of excessive moisture, contains antifungal and hydrophobic additives. Cardboard for creating such plates is also not easy to choose - impregnated. This kind of material can be operated even in places with a high level of humidity, however, provided additional, water-resistant decorative mixtures are used.
  4. GKLVO - waterproof and fireproof gypsum board, mix GKLV and GKLO.It is appropriate to use it where, along with high humidity, high temperatures are also fixed.

Reasons to choose drywall

  1. Light weight. This quality greatly simplifies the installation process and avoids unnecessary load on the load-bearing walls.
  2. Environmentally friendly. This material "breathes" and is absolutely not harmful to the inhabitants of the living space.
  3. Plasticity when wet. This feature of the drywall allows you to model details of a unique non-standard form of varying complexity. To achieve this effect, the sheet is pierced with a needle roller and moistened with water. In this state, it is easy to construct any element with radial lines from it. In addition, after drying, the material restores all the "necessary" properties. It is this fact that has become one of the most compelling reasons for this widespread use of drywall in construction. After all, neither stone, nor ceramic, nor wood products are modeled so easily.
  4. Resistance to fire. Gypsum, which is a basic component, is not at all combustible.
  5. Ease of installation. The assembly of plasterboard forms does not require the presence of any special devices.

Weaknesses of drywall

  1. Exposure to deformation changes in conditions of increased humidity values. Means a level of more than 80%.
  2. Friability. It is forbidden to drive nails into the plasterboard walls, because the sheet can easily burst. All parts are fastened with screws, holes for which make a screwdriver. It is not necessary to hang heavy objects( mirrors, panels, etc.) on the perestings from the GKL.mgo kruvitavpilt.jpg-f2eef0ae7b4def0660aae96801b05803

Where is the use of plasterboard contraindicated?

  • in poorly heated buildings;
  • in buildings with high humidity( more than 80%).

What is fraught with the incorrect operation of drywall?

  • formation of mold and rot;
  • deformed forms;
  • by peeling and destroying the decorative layer.

To exclude the appearance of such unpleasant surprises, you should take care of the installation of air conditioners in the dwelling with excess moisture content in the air. Their functioning will significantly increase the service life of the elements from the GCR.

Where do plasterboard in construction usually work?

  1. For creating wall structures and piers.
  2. In the form of a substrate for the arrangement of floor coverings.
  3. For the manufacture of suspended ceilings.

Drywall is very convenient when you need to make a redesign of rooms without capital transformations. Lightweight plates do not weight the design. Simply put, plasterboard partitions play a role similar to that of stationary screens.

In addition, behind gipsokartonnymi plates easily hide surface defects in the form of chips, cracks, etc.

A particularly high-quality gypsum cardboard Knauf can play the role of an excellent substrate for laminate, linoleum or ceramic facing tiles.

The plasterboard construction, whose standard thickness is 1.25 cm, can be decorated not only with wallpaper, but also with something more heavy. For example, finishing tiles, artificial stone, etc.

Constructions that make from LGA

  1. Arches and domes.
  2. Falshkin.
  3. Overtime.
  4. Columns.
  5. Niches from plasterboard.
  6. Boxes for masking the wires of the lighting system and other communication lines.
  7. The ceiling of plasterboard is multilevel.
  8. Various irregular shapes for room zoning.
  9. Other non-standard products.

Assembling gypsum plasterboard elements

There are some differences in the process of installing a variety of gypsum board elements, but the materials, tools and basic operations are practically the same.

What to prepare in advance

  • Pencil and tape measure for marking.
  • Sharp knife for pruning a sheet.
  • Self-tapping screws and screwdrivers.
  • Metal profiles.
  • Material for insulation.
  • Waterproofing primer.
  • Building mesh.
  • Putty.
  • Sandpaper.
  • Finishing material.

Assembly process

  1. Remove the remnants of the dismantled components, old wiring, garbage. The plane to be trimmed is cleaned from the previous coating.
  2. Make markup considering the size of the GCR.
  3. Make a framework of metal profile, reinforcing it in places where a special load is supposed, using a screwdriver and screws.
  4. Fill the cavity of the carcass with insulation material.
  5. Sew a skeleton structure with a sheet of drywall.
  6. Apply a water-repellent primer to the surface obtained.
  7. Treat the joints with filler using the building mesh. than-plastering-gypsum board 000001-small
  8. Wipe any irregularities with sandpaper.
  9. Apply a layer of finishing putty on the entire plane.
  10. Tile the wall with the selected lining material.
