Technical characteristics of plasterboard for creating partitions, its properties and requirements according to GOST

Often referred to as drywall, plasterboard is an essential component of contemporary construction, especially when dividing spaces. This adaptable material is a favorite among builders and renovators because it combines efficiency and practicality. It is perfect for both residential and commercial projects since it is lightweight, simple to install, and offers a smooth surface that is ready for finishing.

The technical properties of plasterboard are among the most important things to take into account when using it. These characteristics guarantee that the material satisfies the required requirements for performance, durability, and safety. The Russian national standard, GOST, states that plasterboard has to meet certain requirements in order to be approved for use in building. These requirements include, among other things, thickness, dimensions, and mechanical strength.

Plasterboard’s characteristics are also essential to its operation. For example, its ability to withstand fire and act as acoustic insulation is crucial in establishing secure and cozy interior spaces. Plasterboard comes in a variety of varieties to suit different purposes. For example, soundproof boards are made to minimize noise transfer between rooms, while moisture-resistant boards are ideal for bathrooms and kitchens.

Plasterboard must meet GOST standards in addition to these qualities in order to be dependable and safe for use. These specifications address every aspect of the material, including its mechanical and physical characteristics. Adherence to these guidelines ensures that the plasterboard will function efficiently and retain its structural integrity throughout time.

Overall, anyone working in construction or remodeling must comprehend the technical specifications and requirements of GOST-compliant plasterboard. You can achieve a high-quality finish that is both aesthetically pleasing and functional by choosing the appropriate type of plasterboard and making sure it complies with these requirements.

Regulations

You need to make sure that the drywall has the right qualities before using it to build partitions. Regulatory documents are included in the list of requirements. They not only explain the intended features of the sheets, but also their significance.

The primary standardized parameters for drywall are:

1. Classification by type. It is produced depending on the purpose of the sheet. There are 4 categories – GKL (regular), GKLV (moisture-resistant), GKLO (fire-resistant) and GKLVO (moisture- and fire-resistant). (SP 163.1325800.2014)
2. Appearance and shape. Sheets should be rectangular in shape. Permissible deviations from squareness cannot exceed 3 mm for group A and 8 mm for group B. (GOST 6266-97 from 1999-04-01). Damage to corners and longitudinal edges is not allowed. A small number of minor defects are possible (GOST 6266-97 dated 1999-04-01 “Gypsum plasterboard sheets. Specifications").
3. Sheet weight (kg/sq.m.). m). The weight value is determined in the table and depends on the brand of drywall. For example, for gypsum board and gypsum board it is no more than 1.00 of the nominal sheet thickness. For GKLO and GKLVO brands 0 not 0.80 yen and not more than 1.06. (GOST 6266-97 from 1999-04-01).
4. Dimensions. Nominal sizes and maximum deviations are standardized by GOST 6266-97 dated 1999-04-01. Maximum deviations depend on the group of sheets (A and B) and thickness.
5. Fire resistance. This characteristic applies to gypsum board sheets. They must withstand exposure to an open flame for at least 20 minutes (GOST 30247.1-94). The flammability index is standardized by GOST 30244, plasterboard belongs to group G1, flammability group – B2 (GOST 30402), toxicity group T1 (GOST 12.1.044).

Relevant documents must attest to the listed indicators.

Required certificates for plasterboards

The material needs to be certified as fire safe. It attests to the viability of gypsum board use in residential buildings. Another kind of certification is voluntary compliance with drywall, rather than required.

The list of RF PP No. 982 does not include this kind of material. Only holders of a fire certificate are eligible to apply for a voluntary certificate. It is provided by the Ministry of Emergency Situations when finishing evacuation routes with plasterboard. A fire declaration or a document from the manufacturer in compliance with GOST R 54934-2012 is sufficient for the construction of indoor plasterboard partitions.

A certificate of conformance for moisture-resistant plasterboard is also included in voluntary.

Features of plasterboard sheets for creating partitions

Plasterboard sheets need to fulfill specific criteria in order to be used for building partitions on a frame.

Environmental friendliness

There is nothing in drywall that is hazardous to one’s health. If installation technology or operating conditions are not followed, partition issues may occur. For instance, a lot of indoor humidity. It’s critical to choose the lathing material and partition treatment mixture carefully to prevent negative consequences.

Is it comfortable for someone to be in a room with plasterboard walls and does it "breathe"? These are frequently asked questions. The material can be categorized as "breathable" due to the sheets’ porous structure, but the room’s conditions are crucial.

Fire resistance

GCR is fire resistant because it is not flammable. Cardboard is the only material that can burn, not gypsum. It is advised to mount partitions from two sheets of plasterboard to improve their fire resistance. The amount of time before the material’s integrity is jeopardized is used to estimate the fire resistance limit.

For twenty minutes, a standard sheet is heat resistant. Such a sheet will withstand an open flame for 55 minutes and maintain its fire-resistant properties for up to 25 minutes if the plasterboard marking contains the letter O.

Moisture resistance

Certain plasterboard brands have excellent moisture resistance standards. For them, moisture absorption of no more than 10% qualifies as an acceptable indicator. The softening coefficient is the sheet’s second crucial indicator. It is 0.8 for the standard type and 0.45 for GKL.

Thermal conductivity

Gypsum board is a good heat-retention material. The coefficient of thermal conductivity is measured at 0.22-0.35 W / (m × K). Increasing the gap between partitions by 3 to 10 mm will increase their heat conductivity. Installing insulation in between two sheets is also advised. For instance, polystyrene foam or mineral wool.

Weight

While arranging partitions, this feature is crucial. It determines the choice of profile and the quantity of fasteners.

The thickness, proportions of its component parts, and filler content all affect the sheet’s weight. A typical 12.5 mm-thick, moisture-resistant sheet weighs 7.8 kg per square meter.

9.5 mm thick and 5.8 kg per square meter. Consequently, arched with a thickness of 6.5 mm – 5.3 kg/1 sq. m and fire-resistant with a thickness of 12.5 mm – 10 kg/1 sq. m.

Crucial! It is possible for identical sheets to weigh differently between manufacturers.

Size

Typical sizes

• The length of the sheets varies from 2000 mm to 4000 mm in increments of 50 mm.
• The width has two values ​​- 600 and 1200 mm.
• Thickness is the most variable parameter. Values ​​- 6.5; 8.0; 9.5; 12.5; 14.0; 16.0; 18.0; 20.0; 24.0 mm.

The most common thicknesses for sheets are 9.5 and 12.5 mm. The ideal value to create partitions is the last one.

The type of drywall affects the dimensions as well. Standard dimensions for moisture- and fire-resistant materials are 1.2 m for width, 2.3 and 2.5 m for length, and 12.5 mm for thickness. There is only one length of arched—three meters. Its thickness is only 6.5 mm, and its width is standard.

Here’s even more information on selecting the appropriate drywall sizes.

Life time

Structures made of plasterboard are robust. A 25–30 year service life is typical. In the event that the material’s operating requirements are broken, this interval could be substantially shorter.

Installing conventional sheets in highly humid rooms reduces their durability. The use of inferior finishing materials and installation technology violations are the second cause of the decreased service life.

Caution: Avoid hanging bulky household objects on the wall.

What weight can the material support??

For drywall, a load size of 30 kg per square meter is allowed. The partition’s capacity to hold items can be increased. Utilizing a rack profile, for instance, that has walls thicker than 0.75 mm will raise the load to 50 kg per square meter. Attachments up to 12 kg in weight can be placed.

Here’s more information on the subject.

Because it is lightweight and simple to install, plasterboard, which is frequently used to create interior partitions, provides a flexible and effective solution in the construction industry. Its technical qualities, which include durability, sound insulation, and fire resistance, make it the perfect material for both residential and commercial structures. Plasterboard needs to adhere to GOST standards in order to guarantee performance and safety. These standards include moisture resistance, strength, and thickness. Comprehending these attributes and benchmarks is imperative in attaining dependable and superior construction outcomes.

The importance of making the right choice

Installing premium partitions requires, among other things, that all material requirements are met. The conditions in which a material will be used must be taken into account when selecting it. There are four primary categories:

• ordinary;
• moisture resistant;
• fire resistant;
• moisture- and fire-resistant.

Every variety is intended for particular circumstances. When using a standard sheet in a high-humidity or fire-prone area, then:

• its service life will be significantly reduced;
• it will not be able to ensure the safety of residents when conditions change.

Size is regarded as another crucial factor. The sheet won’t give the structure the required strength if the thickness isn’t right. Certain finishes cannot be applied, and certain materials cannot be used to create a profile.
