Which drywall is better - the nuances of the choice of drywall

Drywall has become a versatile material and a godsend for the builder. With it, you can perform a huge amount of work, ranging from leveling the walls and ending with the creation of interior partitions. At the same time, going to the market for the material, it is necessary to take into account that there are many types of this material and it is necessary to decide which one is best for you, in advance. To make the right choice and choose the optimal type for a particular purpose, you should study its characteristics and features.

Advantages of Drywall

Gypsum falls into the category of natural minerals, which began to mine in ancient times. Plasterboard construction is presented in the form of large rectangular sheets of different thickness. What is he like? First, it can be sheets having a different thickness. Installation of thin sheets will be easier, and the design will be easier. For ceilings this is the best option, especially when it comes to suspended ceilings. For walls suitable sheet thickness of 12.5 mm. It should be noted that for rooms with high humidity, for example, a kitchen and a bathroom, you will need a moisture resistant type. The remaining rooms can be sheathed with normal plasterboard.

For the ceiling, choose sheets thinner

The main advantages of the material:

• high environmental friendliness (93% consists of gypsum);
• maintains a given microclimate;
• is used for finishing walls and ceilings, as well as creating partitions and arched openings;
• does not affect the human body and animals;
• affordable cost;
• ease of installation;
• acidity level is almost identical to that of human skin.

There is a list of drawbacks that should be considered when choosing drywall:

• compared to similar materials has less strength;
• when performing high volume finishing additional strengthening of the structure is necessary;
• when installing sheets of drywall in rooms with high humidity, you should not only choose the appropriate type of material, but also carry out additional processing with special primers and solutions;
• during sheet cutting ( if you need to cut a complex shape) Take care of your own protection - wear a respirator and goggles.

Metal frame

The metal frame will increase strength and increase the service life, the tree in this case is inferior to it.

Classification

There are several types of drywall:

1. Normal (GCR). Universal type, which is used in all types of rooms, where no increased moisture resistance is required.
2. Flame-retardant (GKLO). In production, filament yarns are used for reinforcement, and cardboard is treated with flame retardants.
3. Moistureproof (GKLV). Such a drywall is treated with hydrophobic compounds, as well as means that prevent the development of the fungus.
4. Fire and moisture resistant (GKLVO). It is a combination of the two types described above. When working with moisture resistant sheets, it will be necessary to further protect them from the outside with tiles, primer or paint.

In order not to get confused, manufacturers decided to dye each type of sheets in a specific color:

• normal - gray;
• pink or gray with a red stripe - fire resistant ;
• moisture resistant - green and blue.

In addition, several more varieties are distinguished:

1. Restoration - lining of old structures is carried out. Suitable for both walls and ceiling.
2. Laminated - covered with a protective PVC film on the front side. Bad breathing.
3. Reinforced - fiberglass is added during production.
4. Acoustic - soundproof material.
5. Arched - the thickness is not more than 6.5 mm, which causes high flexibility.

After installation, before carrying out the next step of finishing, sheets must be primed on the front side.

Size

Layout of a Drywall Sheet

All standard sheets have rectangular shape, but the parameters of the sheets are different:

• length - 2-4 m;
• width - 0.6-1.2 m;
• thickness - 6 -12.5 mm.

The length has a strict pitch of 50 cm: 2 m, 2.5 m, 3 m, etc. The three-meter-thick sheet is the most popular and most frequently purchased one. With it, you can easily sew up at once the entire wall in height, which facilitates the installation process. The width in most cases is standard - 1.2 m, but also small sheets are on sale.

Moistureproof has the following parameters: 1200/2500/12.5 mm. The arched type is represented by sheets 1200/2500/6 mm.

Thickness

As already mentioned, the thickness varies from 6 to 12.5 mm. It varies depending on the purpose of the material.The minimum thickness is set only for the arched drywall, which facilitates bending. It is specially treated with water in preparation for installation, to make it easier to give the desired shape.

When choosing materials for the ceiling, preference is given to the average indicator - sheets with a thickness of 9.5 mm. Otherwise, due to the large weight of the sheets, an extra load on the structure may be created. Drywall for walls has a standard thickness of 12.5 mm. It also has a moisture-proof look.

Weight

Weight of drywall

It is very important to consider weight, especially when it comes to is about complex design. In addition, the type of fastener, which will be fixed, will depend on the weight. The average indicators in accordance with three common thicknesses show such a result by 1 m ² :

• thickness 6.5 mm - 5 kg;
• thickness 9.5 mm - 7.5 kg;
• thickness of 12.5 mm - 9.5 kg.

Edge

Drywall Edge

Not all drywall sheets have smooth and smooth edges. So, the longitudinal edge can be represented by several options:

1. Straight (PC). It is used for dry installation, when laying of joints is not provided. These include multi-layered trim.
2. Drowned from the front (CC). After installation, it is necessary to putty the joints using reinforcing tape. Time consuming and costly process.
3. Semicircular on the front side (PLC). Reinforcing tape and a small amount of putty are quite enough to connect the joints.
4. Semicircular and thinned from the front (PLUK). Joints are fastened in a similar pattern of 3 types.
5. Rounded (CK). Filling of seams is carried out in 2 stages of puttying.

If you are cutting the plates, a straight edge is formed on the cut without a protective layer. To facilitate the process of sealing seams in this case, the cut is treated with a plane, it is also permissible to use a knife to form a chamfer.

What to look for

Quality

To accurately determine How to choose a sheet of material, you must first focus on its intended use, since each type of work will correspond to a certain type. Secondly, the size of the sheet and its thickness are selected. Before you go to the market or to the hardware store, you need to decide on such moments:

• type of work;
• sheet thickness and length;
• weight;
• edge type;
• manufacturer;
• price.

It’s best to write everything down on a piece of paper and take it with you so you don’t forget anything. Beginners should pay attention to the advice of professionals:

1. Cardboard should not peel off from the gypsum even at the corners.
2. Transporting thin sheets can be problematic, since it will break if it is not secured properly.
3. Pay attention to the color that speaks about the type.
4. The thickness of the sheets will depend on the type of work, type of building and operating conditions.

Drywalls with medium pH will not cause allergies when working with the material. In addition, it can be used for children's rooms.

Drywall is a common building material that is used for many types of work. Which type is better and more suitable for the performance of certain works, the buyer decides. No one will give a clear answer, as each case is individual.
