Basalt plate characteristics

Because of their exceptional combination of strength, aesthetic appeal, and environmental benefits, basalt plates are a common choice in modern architecture. Natural basalt rock, a volcanic stone prized for its durability and resistance to weathering, is used to create these plates. With their dark, frequently matte finish, basalt plates make a striking impression when used as facade cladding that goes well with a variety of architectural styles.

The extraordinary durability of basalt plates is one of their most notable features. They are appropriate for both indoor and outdoor applications due to their exceptional resistance to impact, abrasion, and chemical damage. Unlike other facade materials, basalt plates require less maintenance because of their resilience, which guarantees that they will keep their integrity over time.

Basalt plates are preferred for their sustainable qualities in addition to their strength. Because basalt is a naturally occurring substance formed by volcanic activity, its production has a smaller environmental impact. Its durability and low maintenance requirements also help it have a lower lifecycle impact than materials that need extensive upkeep or frequent replacement.

Basalt plates are valued by designers and architects for their aesthetic versatility as well as their sustainability and longevity. They provide versatility in facade detailing because they can be produced in a range of sizes and shapes. Large, seamless panels or smaller tiles made of basalt can improve a building’s aesthetic appeal without sacrificing structural integrity.

Technical characteristics of the plates from basalt fiber

The characteristics of foreign and domestic basalt slabs are nearly identical. Nearly, as there is only a slight variation in thermal conductivity, vapor permeability, moisture absorption, and degree of combustibility. The variation in the binder, which is represented in the material’s resistance to mechanical loads. In the event that the insulation breaks in the hands even slightly, the material will doubt its ability to function even under its own weight.

Characteristics of basalt plates

Fiber structure of basalt slabs.

Because private home basalt slab insulation is less expensive than foam, it’s highly sought after. However, the material has some very high-quality qualities, so price is not the only consideration.

What is a basalt slab? This heater is composed of volcanic rock. Since this is a stone, stone cotton wool thermal insulation goes by another name. Since vata fibers are inelastic, slabs are the only material that can provide thermal insulation. Their density and weight have an impact on the installation. The slabs are prone to absorbing moisture but do not burn. Simultaneously, they retain heat even after absorbing up to 30% moisture. Slabs of basalt are hard to dry and sometimes unachievable. The stoves can have foil applied to them to reflect infrared radiation.

Technical features of basalt plates:

• Thermal conductivity coefficient 0.038-0.045 W/m*C;
• moisture absorption of not more than 1%;
• vapor permeability 0.3 mg/m*h*PA;
• The combustibility class NG (does not burn);
• Density 30-200 kg/m. cube.

Although it is not as high as the glassy vapor permeability of the basalt mineral plate, it is still sufficient to warm a wooden house. Since wood breathes, as you are aware, thermal insulation should release steam.

A gas boiler used in conjunction with a water heating system provides the least expensive heating for a private home.

Installation of basalt fiber plates

Dowel fungi are essential.

As we’ve already mentioned, the installation techniques for basalt plates mirror their qualities. The range is enormous:

• Roof insulation;
• floor insulation and the ceiling – along the crate and under the screed;
• Wall insulation – internally, external, laying in the inter -stratum space of frame houses.

However, the two circuit schemes that exist are under a layer of solution and laying on a crate. Two key guidelines need to be adhered to in both situations. First, when installing thermal insulation on vertical surfaces, it must be protected from moisture. Secondly, the load on the insulation’s initial tiers must be managed. You must glue basalt slabs for insulation and fasten them to the walls with plastic dowels so that the lower layers do not crack under the weight of the thermal insulation pie. Every three meters, basement profiles must also be installed.

It is important that you select the appropriate density for each type of work so that the slabs made of basalt fiber do not crack under your weight.

Vapor barrier films are required to keep moisture out of thermal insulation. However, keep in mind that since this is a breathing material, air circulation cannot be entirely stopped. Everything must be planned so that any moisture that leaks out of the insulating plate can escape rather than seep into it. Consequently, the second breathing film (diffusion membrane), which is also waterproofing, must be used in the installation if necessary.

The installation method determines how quickly diffusion membranes can be used as well as where the films should be placed. Almost always required, vapor barrier sits between the high pressure zone and the insulation. Where the temperature is higher is the high-pressure zone. For instance, the vapor barrier will be under the basalt plate when warming the ceiling and above it when warming the floor.

Situations where a vapor barrier is not required

Certain manufacturers’ basalt slabs have properties that make it possible to fill the screed without using vapor barrier. However, it will only be advantageous if a protective film is positioned between the insulation and the initial thin layer of screed.

For a single-story home, a sealed two-pipe forced circulation heating system works best.

Manufacturers of basalt mineral slabs

These are Russian-made basalt slabs, called Technonikol.

We’ve already covered the definition and characteristics of a basalt plate. They practically don’t differ from one manufacturer to another, by the way. Actually, the distinction between domestic and Western manufacturers is merely a binding element. Basalt fibers are joined during production by a unique mixture.

Phenol-formaldehyde may be present in the adhesive, but it is not required. Additionally, the cost of the second technology is higher for thermal insulation. The quality of the connecting material affects the basalt plate’s fragility as well. If you take a plate by its edge, sometimes it will just break in your hands.

The variety of offerings in the home market is equally strong. Technonikol, Baswul, Bay, and I are among the brands of basalt slabs produced in the Russian Federation. In general, the latter is a cost-effective material. As an illustration, a 50 mm Rockwood stove costs roughly 1650 rubles per cube meter and costs 1150 rubles per cube meter. The difference will be substantial in large volumes—roughly 25–30%.

Mineral slabs made of basalt fiber are frequently utilized as insulation. What is it? It’s highly technical fibrous thermal insulation.

Basaltic plate: characteristics and application

Setting a goal and calculating the points and surfaces that lose heat the most will reveal that the walls and windows lose the most heat (more than 50%), the roof loses at least 20% of the heat, and the basement loses half of the heat. In construction, a wide variety of insulation compositions are used to minimize heat loss. A basalt plate holds leading positions in this region. What kind of substance is this?

Product manufacturing technology

Some rocks are used as raw materials to make mineral basalt insulation. The most widely utilized materials are clay, limestone, basalt, dolomite, and diabase. P. There are two primary processes in production technology:

1. Getting the melt.

2. Its transformation into thin fibers with the simultaneous introduction of binding components. The basalt fibers used in the manufacture of products usually have a length of 2 to 10 mm, and the diameter does not exceed 8 mm. Actually, the basalt insulation itself is obtained in the process of melting the rocks. The swimming temperature strives for 1500 ° C. At the next stage, the fibers are fastened with each other using an inorganic connecting component (filtration deposition method). At the same time, the process is carried out at the same time, and everything ends with thermal drying. As a result of all these actions, the basalt plate is obtained, the characteristics of which allow it to be used in various fields of industrial and civil construction.

The scope of the plates from basalt

When it comes to customer demand, basalt mineral slabs are currently among the top options. Thermal and insulating materials are the primary areas of application. The construction of residential buildings, other structures, and industrial facilities cannot be finished without this material. Thermal insulation is applied to plumbing, heating, and pipeline systems using basalt plates and cotton wool. The attic, basements, floors, walls, and roofing are all made of the same material that is insulated both inside and outside the rooms.

In flat roof floors, the insulation serves as both the upper and lower layer of sound insulation.

I should also mention, separately, how to properly insulate the facade using a basalt plate. Condensate will form between the insulation and the wall if the house is sheathed from the inside because of the temperature differential, which encourages the growth of an aggressive biological environment (mold, flexible, etc.P.). However, the basalt slabs that are placed on the building’s exterior and cover the facade will keep heat in the space, prevent the growth of mold, and also enhance the building’s overall sound insulation.

Extensive use of basalt insulation in the energy sector, as well as in industrial construction and boiler and furnace thermal insulation at power plants. They pay attention to both mechanical engineering and basalt slabs. This industry uses thermal insulation from automobile buildings, refrigerators, and stoves, as well as insulation made of basalt.

Great quality of material

Because air has a low thermal conductivity, basalt plates have good heat-insulating properties. The free movement of warm air masses within the material is completely eliminated by the multidirectional fibrous structure. When dry, the heat-insulating basalt slabs have a thermal conductivity coefficient between 0.04 and 0.047 W/m².

The density of the material

Customers can purchase mineral basalt slabs from contemporary manufacturers that have densities ranging from 35 to 200 kg/m³. Materials with different indicators are used for different types of construction work. For instance, basalt plates should have a density of at least 30–40 kg/m³ when placed on an inclined roof. If not, thermal insulation will eventually deteriorate. It is recommended by experts to use 80 kg/m³ of basalt slabs for insulating building outer walls. To improve sound insulation in interior partitions, 50 kg/m³ of material is used.

The thickness of the insulation layer: which is best?

This question has a very straightforward response. The two factors that determine indoor heat maintenance are plate density and thickness. Consequently, the better and warmer the insulation, the thicker and denser it is. For instance, the required minimum thickness for a residential attic is 150 mm. At least 30–40 kg/m³ should be the density of the basalt plate. External wall insulation typically has a minimum thickness of 100 mm.

Generally speaking, it is crucial to use basalt-insulating materials correctly in order to create the living room conditions specified by GOST 30494-96 (air temperature in the range of + 20–22 °C, relative humidity–30–45%, absence of drafts).

The stove and cotton are the same?

The melt is the initial phase in the formation of basalt plates, as was previously mentioned. Limestone can be added to the melt at a rate of 10 to 35% of the charge to give basalt fibers greater fluidity. These elements will lessen the material’s resistance to high temperatures and the environment’s harshness. It is impossible to claim that a product with this component makeup is a basalt plate found in nature. This is wool made of basalt minerals.

It would be incorrect, though, to believe that mineral wool is significantly worse than a stove. Up to 600 °C is the maximum temperature that the material can tolerate; at 1000 °C, it begins to change color and melts. The thermal conductivity of the watch is between 0.042 and 0.048 W/m². The substance is not easily affected by mechanical forces.

Noise insulation characteristics of the plates

Because the basalt fibers in the material’s structure are dispersed randomly in various directions, basalt slabs have good acoustics. Such an insulated room greatly lessens the possibility of vertical sound wave excitation. The room’s walls and ceiling become more sound-absorbing and better at isolating air noise. There is a noticeable reduction in the reverb time, which is the gradual drop in sound intensity caused by multiple reflections.

We can conclude that the heaters (cotton wool, basalt plate) are very good at sound-absorbing the room from outside and internal noise.

Environmental friendliness of basalt insulation

Natural materials like limestone and basalt are used to make plates. Once upon a time, frozen magma and the Earth’s interior erupted in basalt. Right now, this substance may be the most prevalent one on the surface of the earth. Calcite is the sedimentary breed that gives rise to limestone. In actuality, basalt slab heating allows you to conserve energy reserves a hundred times over what is required for the product’s production, processing, and delivery.

Strength and hydrophobic parameters

Because the basalt fibers within the plates are arranged randomly, you can attain fairly high rigidity indicators for the insulation. We can discuss the product’s amazing strength parameters and features since the binding components are also added to the composition during the production process. Furthermore, the mineral basalt plate has a long endurance that allows it to retain this strength.

Presently, producers are prepared to provide prospective clients with hard basalt slabs as well as light grades for use with empty structures. The latter can withstand substantial loads. Because of the strength of basalt insulation, mineral wool and slabs can be used in any modern construction system to insulate against noise. They will offer the best quality protection over the course of the structures’ operation.

Hydrophobizing additives are added to the melt during the production stage of basalt plates to give them hydrophobicity, or the ability to avoid contact with water. The Basaltovaya plate thus develops superior water-repellent properties and relatively low water absorption, both of which eventually have a positive impact on the thermal conductivity factor (it drops). In other words, the lower this indicator is, the less saturated the basalt slab is with water.

How not to be mistaken when choosing a brand of material?

Prior to making a purchase, you should determine the area of application and the amount of work required for the basalt plate in order to select the appropriate insulation. All brands have qualities that work best when applied to specific kinds of tasks. For instance, it is acceptable to use softer heat-insulating brands if the material is intended to be used in an environment where there won’t be any increased loads on it. These locations include wall insulation in high-altitude objects (up to four stories), and facade ventilation systems.

When insulating a multi-story building with a ventilated facade that has an infinite air flow rate, half-timer types of basalt plates work best. Experts advise using hard insulation stamps in construction facilities where heavy loads are anticipated.

Danger to people

The harm caused by basalt slabs of human health is a myth or reality? In order to give a certain shape of the plate or mat from basalt, manufacturers add formaldehyde (resin) to the composition of the insulation. A priori are the latter are considered harmful and dangerous for the human body with substances. And in mineral wool, these resins are freely available. If water gets into the insulation, the decomposition processes begin there, and the toxic substances that stand out in this case enter the human body. However, in certified industries, formaldehyde resins and phenol at the time when the insulation is already made, are in a bound state, and are absolutely inert to the environment. From this we can conclude that mineral wool plates are harmful to humans and the environment only if they were made of poor -quality materials and artisanal methods. Such thermal insulation materials, of course, do not comply with sanitary standards, have many harmful impurities in the composition and are dangerous for humans.

This is essentially ruled out if there is a risk of inhaling microscopic basalt plate particles or absorbing them beneath the skin. The fibers of contemporary basalt insulations are soldered together, making it impossible to separate small particles, and they are incredibly strong. In this regard, basalt insulation is far safer than insulation from earlier generations, like glass wool.

Development prospect

The Basaltic plate is still widely used today in many facets of human existence. At the moment, this insulation holds a prominent position in the construction industry. Although basalt insulation is produced through a highly energy-intensive process, it is accessible to a diverse range of consumers with varying financial capacities. And as you are aware, the road to achievement and renown lies in finding the ideal balance between a product’s price and quality.
