Characteristics and features of fireproof plasterboard

Often referred to as fire-resistant drywall, fireproof plasterboard is a crucial component of contemporary construction, particularly when safety is a top concern. It is an essential part in locations where fire hazards are present because it is made to resist high temperatures and stop the spread of flames. In buildings that are subject to strict fire safety regulations, such as residential, commercial, and industrial ones, this kind of plasterboard is frequently utilized.

The distinct composition of fireproof plasterboard distinguishes it from ordinary drywall. Glass fibers are among the additives that help contain the spread of fire. Compared to ordinary plasterboard, it has better heat resistance thanks to these materials. Moreover, fireproof plasterboard usually has a higher density and thickness, which strengthens its protective qualities even more.

The unique characteristics of fireproof plasterboard should be taken into account when selecting materials for walls and ceilings. It not only offers better safety but also good acoustic insulation and a variety of decorative surface options for finishing. This makes it a flexible option for building design, serving both practical and decorative functions.

Does plasterboard burn?

It is required to examine the ingredients of typical gypsum board sheets in order to respond to this question:

1. Base – pressed gypsum with mineral or polymer additives responsible for certain qualities. This layer will not burn even with a constant flame, but the temperature effect disrupts the structure of the board, which leads to a loss of strength.
2. The outer layer of both sides is cardboard. The material is not heat-resistant, so it can catch fire. But the pressing with the base is done very tightly, the coating literally penetrates the structure of the gypsum. Therefore, under the condition of constant exposure to fire, the facing layer most often does not burn, but only chars.

Thus, there are certain restrictions when using regular gypsum board. A unique kind called GKLO is used to cover complicated areas and objects where there is a chance of a fire and where the presence of equipment that emits or conducts high temperatures is anticipated. It is crucial to remember that this material is not completely heat-resistant; that being said, the cladding keeps its structural integrity longer when exposed to open flames, enabling you to exit the room safely.

Note: If you require a surface resistant to high temperatures, it is recommended that you choose the more dependable analogue, GVL boards.

Plasterboard that is fireproof is an essential material for improving building safety because it provides a good mix between fire resistance and usability. It is an indispensable option for walls and ceilings in locations where fire safety is a top concern because of its unique design, which incorporates glass fibers and additives to slow the spread of flames. This kind of plasterboard is a practical and safe option for contemporary construction because it is simple to install, long-lasting, and finishable like standard plasterboard.

What is the difference between fireproof material and ordinary

The key parameters must be compared in order to ascertain how simple GKL and GKLO differ from one another. All category indicators are included in GOST 6266-97.

Composition

Only natural raw materials are used in the mixture to create standard gypsum board material; mineral additives are added to enhance pressing and reinforce the structure.

The following elements are present in the version that is heat-resistant:

• Dihydrate gypsum. Unlike the usual variety, a small percentage of clay is additionally mixed in, which significantly increases stability.
• Filament glass threads. Responsible for reinforcement, the length varies from 3 to 30 mm. Due to the presence of such a component, the degree of resistance to open flame is significantly increased.
• Special reinforcing additives. Play the role of modifiers and fire-resistant stabilizers. Also, crystal hydrates are used as additional substances, helping to preserve the structure due to the release of water in a special form.

These constituents comprise 93-94% of the product and dictate its characteristics. The remaining components are moisture (1%), which is a necessary component of the board, and cardboard (5–6%).

A unique composition is used to glue the facing coating, strengthening the surface and contributing to the increased fire resistance and reinforcing effect of gypsum boards.

Appearance and dimensions

You can quickly tell apart different materials by their color and markings: a non-flammable product is pink with red symbols, while a regular sheet has a gray tint with blue markings for the primary indicators.

Dimensions of typical options for each type:

• Width – 1200 mm.
• Length – from 2 to 4 m, the most common value is 2500 mm.
• Thickness – 9.5 and 12.5 mm. Depending on the manufacturer, it can vary up to 16 mm.
• With dimensions of 120 x 250 x 12.5, the weight of the sheet will be about 30 kg.

The edge changes based on where it is used.

Be aware of this! Furthermore, there is a moisture-resistant type (green with blue markings) and a heat-and moisture-resistant material (GKLV, red markings).

Fire resistance

A distinguishing feature that stands for the duration of the board’s safety when it is exposed to an open flame. It’s also important to know that gypsum board can withstand temperatures as high as 300 to 600 degrees, depending on the type and intensity of the fire.

1. Ordinary sheets can withstand flame for no more than 15 minutes, after which the surface begins to deteriorate. This leads to problems during evacuation.
2. Fire protection boards, the flammability of which is reduced to zero, are able to maintain their structure for 30-50 minutes. Some manufacturers guarantee resistance for up to 60 minutes.

The marking indicates the duration of fire resistance.

Characteristics of GKLO

Technical specifications for the item:

• Flammability class – G1. The material is completely protected from the spread of fire.
• Toxicity – T1. Products of this group do not pose a threat to human health and pets.
• Smoke spread – D1. There is no curtain that makes breathing difficult.
• Flammability – B3 (less than 20 kW / m2).
• Density – from 850 kg / m3.
• Thermal conductivity – 0.22 W / (m K).
• Environmental friendliness. The products do not contain substances that can contribute to the development of allergies or any diseases.

Regulation documents set these requirements, and manufactured goods have to meet them.

Application area of non-combustible gypsum boards

The application of GKLO boards is fairly broad:

1. Creation of boxes for laying air ducts from heating equipment. Sheathing with a conventional variety will not last long.
2. Finishing of rooms that have an increased predisposition to the occurrence of fire. Most often, these are household or technical facilities where electrical devices are located.
3. Heat-resistant gypsum board is suitable for fireplaces and home stoves. It is taken into account that only areas that are not subject to constant temperature exposure are subject to cladding.
4. Sheathing of wooden structures, including attic rooms in the case of untreated floors.
5. Erection of partitions inside which wires and electronic systems will be located.

Because the products are non-flammable, they can be used in any complex area; the walls and ceiling can be sheathed with the slabs. The installation is done in two layers to improve the structure’s dependability and flame resistance; however, this lengthens the evacuation period considerably.

Plasterboard that is fireproof is a necessary material for anyone trying to improve the safety of their house or place of business. In the case of an emergency, it offers a dependable fire barrier, which can be quite helpful. This kind of plasterboard is made of materials that can withstand high temperatures, which helps to contain the fire and give residents more time to safely flee the building.

In addition to being fireproof, fireproof plasterboard is also versatile and easy to work with. It can be applied to a variety of surfaces, including walls, ceilings, and more specialized uses like partitioning. It is a well-liked option for both DIY enthusiasts and builders due to its simple installation.

All things considered, fireproof plasterboard provides a workable way to improve fire safety without compromising the look or functionality of your walls. Whether you’re building a new structure or remodeling an existing one, taking fireproof options into account can ease your mind and make the space safer.
