Gypsum cardboard has long, firmly and for a long time won a worthy place among the variety of materials for construction work due to the simplicity of installation and the presence of many useful physical properties.
Content
Nevertheless, it is interesting what professional builders and designers are guided in their daily practice, giving preferences to this material popular today.
Some examples of how drywall in construction are presented in the photo below.
Classification
Gypsum cardboard is a plate that has a gypsum core framed on both sides by sheets of facing cardboard.
The gypsum base of the GCL includes different additives that endow the resulting material with certain useful properties. According to the type and purpose of additives present in the starting raw materials, it is customary to divide drywall into the following categories:
- GKL is the most ordinary drywall, without additives at all. Its purpose is the sheathing of wall structures and ceilings in buildings with acceptable temperature values \u200b\u200band a low indicator of moisture in the air.
- GCL - gypsum cardboard with reinforcing inclusions. This type of material is created for the construction of structures in places where special attention is paid to the observance of fire safety.
- GKLV - the type of drywall that is not amenable to the pernicious effect of excess moisture, contains anti -info -hydrophobic additives in the composition. Cardboard for creating such plates is also chosen - impregnated. This type of material can be operated even in places with a high level of humidity, however, subject to additional, waterproof decorative mixtures.
- GKLVO - waterproof and refractory drywall, MIX GKLV and GLLC. It is appropriate to use it where, along with high humidity, high temperatures are also fixed.
The reasons for which it is worth choosing a drywall
- Small weight. This quality greatly facilitates the installation process and avoids excessive load on the load -bearing walls.
- Environmental friendliness. This material “breathes” and is absolutely not harmful to the inhabitants of living space.
- Plasticity with moisture. This feature of drywall allows you to simulate parts of a unique non -standard shape of various complexity. To achieve this effect, the sheet is pierced with a needle roller and wetted with water. In this state, it is easy to build any element with radial lines from it. In addition, after drying, the material restores all the “necessary” properties. It was this fact that became one of the most good reasons for such a widespread use of drywall in construction. After all, neither stone, nor ceramic, nor wooden products are modeled so easily.
- Resistance to fires. Gypsum, which is a basic component, is not at all a fuel.
- Simplicity of installation. The assembly of drywall forms does not require any special devices.
The weaknesses of drywall
- Exposure to deformation changes in conditions of increased humidity. The level of more than 80%is implied.
- Fragility. It is forbidden to drive nails into the drywall walls, because the sheet can easily burst. All details are attached with screws, holes for which they make a screwdriver. You should also not hang heavy items (mirrors, panels, etc.) on rheasts from GKL.
Where is the use of drywall contraindicated?
- in poorly heated buildings;
- in buildings with high humidity (more than 80%).
What is fraught with incorrect operation of drywall?
- the formation of mold and rot;
- deformations of forms;
- exfoliation and destruction of the decorative layer.
To exclude the appearance of such unpleasant surprises, you should take care of installing air conditioners in the dwelling with excessive moisture in the air. Their functioning will significantly increase the service life of elements from GKL.
Where do gypsum cardboard usually use in construction?
- To create wall structures and pieces of paper.
- In the form of a substrate during the arrangement of flooring.
- For the manufacture of suspended ceilings.
Gypsum cardboard is very convenient when you need to redevelop rooms without capital transformations. Light plates do not weight the structure. Simply put, partitions from drywall play a role similar to the roles of stationary screens.
In addition, behind drywall plates, it is easy to hide surfaces in the form of chips, cracks, etc.
And Knauf can play the role of an excellent substrate for laminate, linoleum or ceramic facing tiles.
Hypsum plasterboard structures, the standard thickness of which is 1.25 cm, can be decorated not only with wallpaper, but also by something more severe. For example, finishing tiles, artificial stone, etc.
Constructions that are made from LHC
- Arks and dome.
- Falshkamyamins.
- Restois.
- Columns.
- Niches made of drywall.
- Boxes for masking the wires of the lighting system and other communication lines.
- The ceiling made of drywall is multi -level.
- A variety of elements of irregular shape for zoning the room.
- Other non -standard products.
Assembly of drywall elements
There are some differences in the process of installing a variety of drywall elements, but materials, tools and basic operations, almost the same.
What to cook in advance
- Pencil and roulette for marking.
- A sharp knife for cutting the sheet.
- Self -tapping screws and screwdrivers.
- Metal profiles.
- Material for isolation.
- Waterproofing primer.
- Construction grid.
- Putty.
- Sandpaper.
- Finishing material.
Installation process
- Remove the remnants of the dismantled elements, old wiring, garbage. The plane that is planned to be finished is cleaned of the previous coating.
- Mark, given the dimensions of the GCL.
- Build a frame made of metal-profile, strengthening it in places where a special load is supposed to be using screwdrivers and screws.
- Fill the cavity of the frame with material for insulation.
- Sew the frame structure with a canvas of drywall.
- Apply a water -repellent primer to the resulting surface.
- Process the seams with putty using a construction grid.
- Sub the irregularities with sandpaper.
- Apply a layer of finish putty to the entire plane.
- Get the wall with the selected facing material.
