Drywall is quite popular in the modern market. It is used when carrying out all kinds of repair work. With its help, walls and ceilings are aligned, niches, fireplaces, arches, as well as suspended structures are created. Usually, for a successful work, it is necessary to take into account the quality of building materials. You need to know how much drywall sheets weigh.
Before considering the standard weight of drywall, the methods of calculating it, you need to understand what kind of material it is. It is used for decoration and protection. It has a compressed gypsum core, which is covered with two layers of a special coating on top. As a rule, this is reinforcing cardboard. From an environmental point of view, this material is absolutely harmless. It does not contain harmful substances, it is not flammable.
One of the characteristics of drywall is thickness. This affects the weight of the sheets. It changes depending on what the drywall is intended for. The thickness limits are 0.65 - 1.25 cm per 1 sq. m, while different types of gypsum plasterboard material can have different thicknesses. For example, arched drywall sheets are usually 0.65 cm, the material for the ceiling is 0.95 cm, for the walls, material with a thickness of 1.25 cm is used.
The next characteristic is represented by the width. In accordance with the standard, it is 12 cm. But there is a material on the domestic market with a smaller width. To calculate the weight of the gypsum board used in each specific case, you can use the specific gravity. In other words, the characteristic of the density of drywall, due to which the calculation of weight per volume is carried out.
Knowing the weight of a structure allows you to know how many fasteners are required. Usually, this characteristic ranges from 1200 to 1500. To calculate the weight of the entire structure, a formula is usually used in which the thickness of the gypsum board is multiplied by a constant average gypsum density equal to 1.35. In addition, it must be said about thermal conductivity. This characteristic of plasterboard material ranges from 0.22 to 0.35. The best thermal insulation materials have lower thermal conductivity.
One of the most important characteristics is the strength of the material. It depends on its indicator what level of weight load the gypsum board can withstand so that there is no damage left on it. This indicator depends on the thickness of the sheets. If it is less than 1 cm, then the structure is unlikely to withstand more than 15 kg.
The limits from 1 to 1.8 cm can withstand up to 18 kg. For the reliability of the entire structure, it is better to have information about the parameters of the frames. You can transfer a volumetric drywall with a size of 9 mm or 10 mm in the trunk of a passenger car.
Plasterboards on the market are presented in several variations. They can be classified according to several criteria. The nature of the conditions in which it is planned to use drywall sheets determines the presence of several types of material.
The species is the most common and is used more often than others. The scope of the variety is in structures that are not designed for a large weight load. As a rule, they are used to create walls, suspended ceilings and partitions.
Moisture resistant, their purpose is to decorate rooms with excessive moisture levels. This material is usually used to decorate the walls and ceilings of bathrooms or kitchens.
Fire-resistant, scope - premises, its individual parts, which are exposed to high temperatures. This can be ventilation, air duct or fireplace trim. Also, the scope of application of fire-resistant gypsum plasterboards are premises that require increased fire protection. Usually these are children's rooms.
Moisture-resistant material options, their scope of application is baths and saunas, combining the characteristics of high temperatures and high levels of humidity. This variety is rightfully considered exotic.
GKL can vary in width and purpose. A state standard has been established, according to which a certain weight is established for each type of drywall sheets. In moisture-resistant drywall 1 sq. m must have a weight of up to 1 kg. In this case, the sheet thickness is equal to 1 mm. GKLO and GKLVO usually have a weight range of 0.8-1.06 mm.
In accordance with the thickness, variations can be distinguished for walls, drywall and arches. The walls are sheathed with plasterboard sheets, usually 1.25 cm thick, this also applies to partitions. Drywall with a thickness of 0.95 is usually placed on the ceiling. For arches, GKL with a thickness of 0.65 cm is used. Such sheets are the thinnest, they bend easily.
Drywall will weigh differently depending on the area of the sheets. The standard size of the sheets is equal to an area of 3 square meters. m. But there are other parameters on the market. For example, drywall is 2 - 4 m long, and 0.6 m wide. Usually non-standard sizes are used to sheathe loggias and balconies, or they form slopes with their help.
Calculation of the weight of 1 sq. m
If the drywall sheets are 0.65 cm thick, they will weigh about 5 kg. With a thickness of 0.95 cm - about 7.5; 1.25 - about 9.5. Thus, to calculate the weight, it is enough to know the values of the area and thickness. All manufacturers on the market are required to indicate the weight of the building materials supplied along with the brands and sizes of products.
The weight of drywall sheets indicated by the manufacturer does not always coincide with the real value, since this material is moisture-absorbing. It can get heavy in high humidity. Among the manufacturers of quality products, the Gyproc brand can be distinguished. The products are of high quality and durability.
In accordance with the standard established by the state, gypsum plasterboards must necessarily weigh up to 1 kg for each mm of thickness. For GKLO and GKLVO, the norm usually ranges from 0.8 to 1.06 kg.
Ceilings experience a certain load, this factor must be taken into account during repairs. It is possible to reduce the load on the floor by using multilevel ceilings.
Transport and storage
Plasterboard is a fragile material that is easily damaged. In order not to waste time and money on their replacement or restoration, you need to follow some rules for their storage and transportation. When storing drywall sheets, they must be placed horizontally on a flat surface. The same goes for transportation. This is due to the fact that the sheet can be damaged by any pebble or bolt, it can crumble even from its own weight.
It is necessary to transfer the material vertically together. Otherwise, the drywall may break. To move, you need to support it from the bottom side, not allowing it to swing. Professional loaders usually use a special device (a kind of hook). Due to it, it is more convenient to transfer drywall.
It is important to protect the material from high levels of moisture. Do not store the material in high humidity conditions.
The opinions of experts in the field of construction and surface finishing indicate that the weight of drywall is of particular importance when carrying out any type of work with it. The thicker it is, the more difficult it is to work with it, the more accurate the master should be.Each type of material is designed for its own type of work, - the masters agree. It is impossible not to take into account the type of raw material, otherwise it may cause a reduction in the shelf life.
With the correct calculation of the thickness and the presence of the necessary impregnation, the material will be durable, - noted in the comments indicated on the forums dedicated to finishing work.
