When building houses Special attention is given to thermal insulation. In the cold winters of our country, such additional protection will be very useful. Insulation will allow you to significantly save on heating costs and increase the comfort of living in your home. There are many thermal insulation materials on the modern construction market. Everyone has their pros and cons, and sometimes it is very difficult to make a choice. To avoid mistakes, it is better to learn more about the characteristics of each. In this article we will talk about such material as liquid thermal insulation Corundum. There will be data on its characteristics and talk about the advantages and disadvantages.
Features of the material
Thermal insulation with Corundum Lately became very popular. This modern method using special ceramic heat paint. Externally, this material is not much different from ordinary paint. All the most important things are hidden inside.
Liquid thermal insulation Corundum is made from a mixture of water-acrylic solution and ceramic fillers. The first component allows the material to evenly distribute heat-insulating elements over the entire surface. And hollow ceramic spheres of microscopic size act as a heat-insulating element.
Due to its composition, thermal insulation with Corundum is carried out quickly and evenly covers the entire area, going even into the most hidden areas.
Characteristics
can be carried out on any surfaces. Thermal paint adheres well to concrete, brick or stone masonry, plastic or metal structures.
This material easily withstands a wide range of temperatures. Liquid thermal insulation “Corundum” does not lose its characteristics both in extreme cold (up to -65 degrees) and in strong heat (it can easily withstand temperatures up to +260 degrees).
Possessing low thermal conductivity, even a thin layer of material retains heat perfectly. Corundum thermal insulation with a thickness of only 2 mm works more efficiently than a layer mineral wool 60 mm thick.
Basic specifications liquid thermal insulation material Corundum are as follows:
- bending elasticity – 1 mm
- adhesion to concrete – 1.28 MPa;
- adhesion to brickwork – 2.0 MPa;
- adhesion to steel surfaces – 1.2 MPa;
- thermal conductivity – 0.0012 W/m °C;
- heat transfer – 4.0 W/m °C;
- vapor permeability 0.03 mg/mh Pa
All these characteristics make Corundum the best heat insulating material.
Advantages and disadvantages
Liquid thermal insulation Corundum is modern high-tech material. E If we talk about its advantages, it is worth noting the following:
But this material also has its disadvantages. Yes, they include high cost heat insulator Corundum. In addition, the material is new, so all its declared characteristics have not yet received their practical confirmation.
Types of material
Liquid thermal insulation material Corundum Available in several versions. The manufacturer offers to purchase the following varieties:
- Classic - this product is widely used in roofing and facade works. This brand is also excellent for thermal insulation. interior spaces with any type of coating. Classic is a universal and highly effective thermal insulation product;
- Anticorrosive This material is primarily used for anti-corrosion coating metal structures. In this case, the protective layer can be applied directly to areas with rust, without any pre-treatment;
- Facade - this type of thermal insulation material is specially designed for covering concrete, slag concrete and foam concrete walls and structures. It is applied in a thicker layer, which speeds up work and improves thermal insulation qualities. This type is most often used when finishing house facades;
- Winter. Not always everything thermal insulation work manage to finish in the warm season. If insulation is carried out at temperatures down to -10 degrees, then you need to use this particular type of thermal paint.
There are a number of other types of this liquid thermal insulation material, but they are used less frequently. But no matter what brand of Corundum you use, high thermal insulation properties of the coating are guaranteed.
How to apply?
Whatever type of liquid thermal insulation Corundum you use, before applying it you must properly prepare the foundation. First of all, the entire surface is cleaned of debris and pollutants. Weak areas, “cement laitance”, and old molar coating are removed. If there are gaps and cracks, they are sealed sand-cement mortar. Then any surface must be treated with an abrasive wheel or a simple metal brush.
The paint itself for thermal insulation must be mixed according to the attached instructions from the manufacturer. The most important thing is to mix it by hand. If you use mechanical method, the ceramic microspheres may be damaged and the thermal insulation effect may deteriorate.
The heat paint itself is applied manually or using painting machines. You simply paint the surface. During operation there is no need for protective devices for breathing or forced air flow. Corundum is absolutely safe for humans.
Conclusion
Corundum thermal insulation is a modern, high-tech product. With its help, you can effectively insulate houses and any other structures. Therefore, despite the rather high price, Corundum is very popular, both among construction companies and among private homeowners. And its ease of use allows anyone, even an inexperienced user, to cope with insulation.
Technologies in the field of building insulation do not stand still. A new development has recently been introduced into production, making it possible to maximally improve and facilitate this process. This material is called thermal insulation corundum. Its use is not yet so common and not universal, but there is confidence that it has a great future, and it will make revolutionary changes in the thermal insulation market.
Important. The material has passed all tests and is fully certified.
Corundum has a liquid consistency. Thermal insulation resembles a suspension or paint white. You can insulate a surface made of any material with it. The application method is the same as for regular paint. After drying, a specific coating with elastic properties is formed. It has unique technical and thermal insulation characteristics. For comparison: 1 mm of corundum can replace 60 mm of mineral wool or a wall one and a half bricks thick.
The composition of the coating is unique
The composition of this coating is unique. Physicists and chemists from Europe and the USA have been working on its development for many years. It consists of microscopic ceramic balls filled with vacuum (rarefied air). These microbeads bind acrylic polymers High Quality, thanks to which the material has excellent adhesion (adhesion) to all surfaces (plastic, metal, propylene).
The intensity of the action of rarefied air molecules located in spherical cavities gives liquid thermal insulation unique properties.
Corundum also contains water. It occupies 47% of the total volume. After application, part of the water evaporates, and part participates in the hardening process of the applied thermal insulation.
In addition to the base, corundum contains additives that prevent corrosion and the formation of mold and mildew in conditions of high humidity.
Technical characteristics and modifications
Thermal insulation performance
Ultra-thin thermal insulation corundum compares favorably with other insulation materials in its characteristics:
- thermal conductivity – 0.0012 W/mS;
- heat transfer – 4.0 W/mS;
- vapor permeability – 0.03 Mg/MchPa;
- water absorption – 2%;
- t of operation - -60°С+260°С;
- service life – more than 10 years;
- low turnover;
- safety for humans and the environment;
- does not support combustion (chars at +260°C).
The paint protects the treated surface from condensation and is not destroyed by ultraviolet radiation, aqueous saline solutions and alkali.
Unlike other insulation materials, corundum does not create any load on load-bearing walls and other building structures, and also protects metal elements from temperature deformation.
The application of thermal insulation results in a seamless coating that does not allow cold to penetrate through the joints (as when installing other insulation).
Important. Corundum paint allows you to use painted surfaces without any problems. They can be inspected at any time, which makes it possible to restore the damaged thermal insulation layer in a timely manner.
There are 4 modifications of ultra-thin insulation:
- Corundum Classic. Thermal Insulation Paint Processing different types plastic, propylene, metal, brick, stone.
- Corundum Anticorrosive. Designed for thermal insulation of metal surfaces covered with rust.
- Corundum Facade. Liquid facade thermal insulation. Suitable for indoor use.
- Corundum Winter. It is distinguished by the presence of frost-resistant additives (tiny pieces of foam glass, fire retardants and inhibitors), allowing the paint to be used at temperatures down to -10°C.
Application and consumption of corundum
For correct application paint there are instructions for its use. The main role here is played by the preparation of the surface to be painted:
- We get rid of all unevenness on plaster, concrete or brick, cover up cracks, remove old paint, dirt and dust.
- It is better to first rough out serious damage and then carry out finishing plastering (this is important for walls).
- We coat the area to be treated with an antifungal agent, let it dry and apply one or two layers of primer.
- We gradually apply heat-insulating paint corundum to the finished dry surface. First, one layer 0.5 mm thick, then a second (the first must be completely dry) of the same thickness and a third similar layer. For greater effect, the layer of heat-insulating paint should be 1.5 - 2 mm.
- Decorative coatings are applied on top of the thermal insulation (after it has completely dried).
When calculating paint consumption, first of all it is necessary to take into account the material and thickness from which the surface needed for treatment is made. We also take into account the thickness of the thermal insulation layer.
Advice. Thermal insulation corundum can be used at a temperature of the surface to be painted ≥+5°C ≤ +150°C.
Laboratory studies have shown that the consumption of corundum thermal insulation with a layer thickness of 1 mm is 1 l / 1 m 2 (without taking into account the method of application and the type of material being painted). For actual use, we add the percentage of overexpenditure (working in calm weather, without wind):
- brush painting of metal – 4%, concrete – 5-10%;
- when applied with a spray gun on metal - 15-25%, on concrete - 35-40%.
To make the most accurate calculation, use the corundum thermal insulation consumption calculator. To do this, you will need instructions on the website and the following values: the length and height of all walls and the number of layers of paint. These values are entered into special windows on the computer monitor screen, and a calculation is made.
As we see, corundum thermal insulation is perfect choice for insulation. The uniqueness of the development, excellent technical characteristics, ease of application - all this contributes good result and, importantly, a significant reduction in labor costs and working hours.

Liquid ceramic thermal insulation CORUNDUM consistency resembles regular paint white , which can be applied to any surface.
Liquid thermal insulation CORUNDUM consists of a high-quality acrylic binder, an original developed composition of catalysts and fixatives, ceramic ultra-thin-walled microspheres with rarefied air. In addition to the basic composition, special additives are introduced into the material, which eliminate the appearance of corrosion on the metal surface and the formation of fungus under conditions high humidity on concrete surfaces. This combination makes the material is light, flexible, extensible, with excellent adhesion to the surfaces being coated. After drying, an elastic polymer coating, which has unique thermal insulation properties compared to traditional insulators and provides anti-corrosion protection.
Liquid thermal insulation CORUNDUM- a new generation of thermal insulation that has proven its reliability as a means of maintaining surface temperature, suitable for use in almost all atmospheric conditions. In addition, thermal insulation paint CORUNDUM helps fight condensation on cold surfaces and corrosion (the Corundum modification "Anticor" contains special inhibitors of the corrosion process). Liquid thermal insulation CORUNDUM passed tests according to standard standards in Russia, in neighboring countries (Belarus, Ukraine, Kazakhstan), in the European Union, in Asia ( South Korea). The product has high performance in such characteristics as elasticity and resistance to weathering (after polymerization, drying). The microstructure of liquid thermal insulation provides excellent thermal properties, and ensures a long service life without the need for repeated repairs. IN standard conditions operation, the service life of liquid thermal insulation Corundum will be at least fifteen years. The full service life of this thermal insulator, subject to technological process application and the absence of an aggressive environment will be almost half a century.
PRINCIPLE OF OPERATION OF LIQUID THERMAL INSULATION CORUND
The essence of the unique thermal insulation properties of liquid ceramic material CORUNDUM consists of spheres that are capable of not only thermally insulating the covered body, but also retaining heat.
AREAS OF APPLICATION OF LIQUID THERMAL INSULATION CORUND
The Corundum material is highly effective in thermal insulation of building facades, roofs, interior walls, window slopes, concrete floors, hot and cold water supply pipelines, steam pipelines, air ducts for air conditioning systems, cooling systems, various containers, tanks, trailers, refrigerators, etc. It is used to eliminate condensation on cold water supply pipes and reduce heat loss according to SNiP in heating systems. The material is used at temperatures from - 60 ˚С to + 250 ˚С. The service life of the material is from 15 years.
ADVANTAGES OF LIQUID THERMAL INSULATION CORUND
- Applied like paint, it acts as a thermal barrier.
- A 1mm thick coating layer provides the same insulating properties as 50mm roll insulation or brickwork 1-1.5 bricks thick.
- It is an insulating material that does not support combustion. At a temperature of 260°C it chars, at 800°C it decomposes with the release of carbon monoxide and nitrogen oxide, which helps slow down the spread of flame.
- Environmentally safe, non-toxic, does not contain harmful volatile organic compounds.
- Does not break down when exposed to UV radiation.
- It is not permeable to water and is not affected by an aqueous salt solution. The coating protects the surface from moisture, atmospheric precipitation and temperature changes.
- An additional advantage that liquid thermal insulation provides is the ability to work in rooms without additional ventilation. Application of liquid thermal insulation is much easier to apply and allows you to save on installation compared to the previous generation of thermal insulation. The use of an ultra-thin thermal insulator also saves space by reducing the thickness of the insulation layers. Additionally, the use of this thermal insulation material makes it possible to radically weight reduction of the entire structure and significantly reduce the cost of building materials. Not to mention the increased comfort of being in a thermally insulated residential premises and savings on heating and air conditioning costs.

MODIFICATIONS OF MATERIALS "Corundum Classic". Ultra-thin heat insulator, has unsurpassed thermal physics, plasticity and lightness. A plastic Euro bucket 20 l “Corundum Classic” weighs only 10.3 kg. During transportation and storage, liquid thermal insulation “Corundum” practically does not break down into fractions. "Corund Anticor". A unique material that can be applied directly to a rusty surface. It is enough to simply remove the “damp” (loose) rust with a metal brush, after which you can apply Corundum Anticor thermal insulation, following the instructions. Thermal insulation "Corundum Anticor" is a highly effective thermal insulation coating with additional anti-corrosion properties, and not just a preservative and corrosion modifier. All technical characteristics, requirements, instructions for use are the same as for the basic material “Corundum”. Application of liquid thermal insulation “Corundum Anticor” for thermal insulation of existing structures and pipelines significantly reduces labor costs, since it does not require special preparation of the working surface. Thermal insulation “Corundum Anticor” can be applied as the first layer, and for subsequent layers (in order to save money) you can use “classic” thermal insulation “Corundum”. "Corundum Facade". A material that can be applied in layers with a thickness of 1 mm at a time, and has high-quality vapor permeability facade paint. Ultra-thin heat insulator “Korund Facade” - designed specifically for concrete surfaces. Due to high heat-reflecting qualities and reduced labor costs for application, compared to similar ultra-thin thermal insulators at least doubled, will become ideal solution in the field of construction professional thermal insulation. Thermal insulating paint “Korund Facade” also showed excellent results together with the modification “Korund Anticor”. For example, the calculated thickness of ultra-thin thermal insulation for a ferrous metal tank is 2.5 mm. Astratek, mascoat, alfatek, etc., as well as our basic modification “Corundum Classic”, needed to be applied in at least 6 layers (1st layer of primer + 5 layers of 0.5 mm each). Our solution is just three layers!- 1st layer. 0.5 mm “Corundum Anticor” (Not only fixing corrosion but also a converter, adhesive and waterproofing agent (due to the high rate of film formation); 2nd layer, after 24 hours - 1 mm “Corundum Facade”; 3rd layer, after 24 hours - 1mm “Corundum Facade”. The following modifications are being prepared for industrial production (laboratory samples are already available): TECHNICAL CHARACTERISTICS OF LIQUID THERMAL INSULATION CORUND

- Avoid freezing!
Preparing the surface for application
Prepare the surface for application of the material: remove loose areas, open cracks, remove oily inclusions, clean the concrete from cement laitance, repair the surface, including inter-brick joints to reduce material consumption and excavations deeper than 5-7 mm, with cement-plaster compounds. Clean the surface using a sandblaster, a metal brush or abrasive wheels to remove the gloss on the surface and remove falling off and crumbling structural elements.
After mechanical treatment of the surface, thorough dust removal should be carried out using brushes or blowers. After dust removal, the surface must be washed with water to remove dirt, remaining dust, etc. Wait until it dries completely. Concrete, brick and similar surfaces must first be primed with YAKHONT deep penetration primer. If it is necessary to apply CORUND FACADE coating to metal surfaces– the metal must first be protected from corrosion.
It is recommended to first apply 1-2 layers (0.5 mm each), depending on the condition of the metal surface, modification CORUND Anticor. Concrete humidity when applying CORUND FACADE should not exceed 4%, air humidity during application should not exceed 80%. In the presence of oily and greasy stains on the surface - they must be removed with a solvent.
Preparation of insulating coating CORUND FACADE
CORUND FACADE is ready for use; it must be mixed, if necessary, adding a little distilled water, immediately before application to a previously prepared surface. The amount of water also depends on the temperature of the application base and subsequent use. When applied to a surface with a temperature from +7°C to +80°C, the amount of water added to the material can be no more than 5% when applied with a brush and no more than 3% when applied mechanically (airless spraying apparatus). When applied to surfaces with temperatures above +80 °C, it is necessary to first reduce the temperature by applying several primer layers of CORUND FACADE material, diluted with 40-50% distilled water according to the scheme (see coating application). At long term When stored inside the container, separation into fractions is allowed.
Do not over mix! When using a drill with a paddle attachment or a mixer, the maximum permissible mixing speed is 100 rpm. Exceeding the rotation speed will lead to the destruction of the microsphere and a radical reduction (or cancellation) of efficiency thermal insulation coating. Using vertical movements of the blade to immerse the thickened part in the liquid, turn on the drill and slowly begin to rotate the blade, mixing the curds with the liquid.
Stir until the product resembles cream. Approximate mixing time:
- Mixer 3-8 minutes,
- Manual stirring for 7-10 minutes.
If the task is to eliminate condensation, a “coat” of frost, fungus, mold, the material is applied with a minimum addition of water, with a maximum interlayer interval (over 24 hours).
Coating
It is recommended to work with Corundum Facade using a soft brush with long natural bristles or an airless spray. You can apply the coating to small surfaces or areas with complex configurations using a soft brush. Surfaces from 100 m2 can be treated using an airless sprayer with a material pressure at the nozzle exit of 60-80 bar
Important: not all airless sprayers are suitable for working with Corundum Facade paint!
The insulating coating can be applied to surfaces with temperatures from +7ºС to +120ºС. You cannot work in wet weather, because... The material is liquefied by water and will not dry out. The period for complete drying of one layer of coating with a thickness of 1 mm is at least 24 hours. Apply next layer It is possible only after the previous layer has completely dried - after 24 hours at a temperature not lower than +7°C during the entire drying process. A layer of about 1 mm is obtained with approximately three to five “passes” of the sprayer or brush. Applying the material in a thicker layer is unacceptable, since this leads to the formation of a moisture-proof film on its surface, which in turn prevents the complete evaporation of the moisture contained in it, which will lead to the annulment of the thermophysical properties and deformation of the coating.
When applying the material to a surface with a temperature above +80ºС, the material boils and “sets” very quickly, so the material must be diluted with water. It is recommended to prime the surface with a 40-50% aqueous solution of the material. When applying CORUND FACADE on surfaces with temperatures above +80 °C, the thickness of the maximum layer within 24 hours should not exceed 0.5 mm! The hotter the application surface, the more the material is diluted. The diluted material is applied with quick short movements; with this application the layer will be very thin. The drying time for each layer is at least 1 hour. Such layers are applied until the applied material stops boiling on the surface. After this, allow to dry for 24 hours. Then the material is applied according to the usual scheme - with the addition of 3% to 5% distilled water in layers up to 1 mm with interlayer drying for 24 hours. The thickness of a layer of 1 mm can be determined by a thickness gauge of the “painting comb” type, a material consumption of 1.1 liters per 1 m2 (approximate consumption when applying the coating with a brush on a flat surface) or the thickness of the “optical density” of the material (so that the underlying base does not shine through the material). The material consumption is affected by the type of surface and method of application. Total thickness coatings and the number of layers are determined by thermal engineering calculations.
Safety precautions when working with CORUND FACADE
At normal conditions the product is safe. If the room is well ventilated or work is carried out outdoors, respirators are not required. In rooms without ventilation, use standard respirators. Use safety glasses to protect your eyes. Use gloves and protective clothing to protect your skin.
If the product gets into your eyes, rinse your eyes immediately. running water within 15 minutes. If irritation persists, consult a doctor. In case of contact with skin, wash with soap and water.
The product in liquid state is not flammable. In the event of a fire in structures or structures on which the coating has been applied, use water, foam, dry chemicals And carbon dioxide. In case of product spillage, use any absorbent material such as sand, soil, etc.
Storage and transportation conditions
The CORUND FACADE material is stored in a tightly closed container at a temperature from +5 °C to +30 °C, air humidity no more than 80%, away from direct sunlight. Transportation is carried out by any type of transport at temperatures above +5 °C away from direct sunlight. Packaging of cargo for transportation must ensure the correct installation of containers and the safety of the container. Violation of the integrity of the container leads to damage to the material.

Liquid ultra-thin insulation (as an analogue) is a new word in the matter of insulating structures. Standard methods of thermal insulation are still good, but little by little they are being replaced by more effective solutions.
Liquid insulation is just such a solution. It is able to protect the structure from freezing, while being essentially more paint and varnish material, than insulation in the form in which we usually imagine it.
In this article we will present for your consideration all the nuances and features of liquid thermal insulation Corundum.
1 Features of liquid insulation
Liquid thermal insulation Corundum is produced by the association of companies Fulleren. They have been producing this material for many years and have managed to achieve quite serious results.
Note that liquid-type thermal insulation was not invented quite recently. It is intended for the same insulation work, but it is reproduced in a unique form.
Standard insulation is a special material with low thermal conductivity. It cannot transfer heat and perfectly delimits zones with different temperatures due to the presence of a large amount of air in it.
That is, the insulation has a certain thickness and is laid on the surface of the walls, thereby protecting them from the effects of external temperatures. As you yourself know, the working thickness of the slab can reach up to 10 cm or even exceed this figure.
But the characteristics of the heat-insulating material Corundum are completely different. It’s not for nothing that this insulation is called liquid. If you look at it uninformed, the composition can be confused with ordinary paint.
Indeed, thermal insulation of this type resembles paint in consistency, is applied like paint, and even forms a similar coating. However, after application, an ultra-thin thermal insulation film with unique parameters is formed.
This is possible thanks to the unique structure of the Corundum material (as with).
1.1 Insulation composition
In addition to the standard name in the form of liquid thermal insulation, this insulation has another name - ceramic.
It is not called ceramic because it consists of ceramics or forms a ceramic surface. Quite the contrary, the main filler in Corundum insulation is an acrylic-type polymer, only more dense.
Ceramic insulation consists of ceramic hemispheres with insulated filling. These hemispheres allow you to create insulation with a thickness of 1-2 mm.
However, ultrathin film does not consist of hemispheres alone. It also contains anti-corrosion additives, polymers, etc.
Together they form insulation for walls, floors, ceilings, pipes and generally any structures available to you.
After hardening, the polymer sets, forming a very strong film; inside it there are frozen spheres that occupy more than half of the space. They push away anyone thermal energy, protecting the insulated structure no worse than a quite impressive-sized layer of mineral wool.
1.2 Operating principle
The instructions for use state that Corundum insulation with a thickness of only 1 mm can replace up to 5 cm of mineral wool insulation. That's really true ultra-thin thermal insulation. But how does she manage to do this?
And everything is very simple. The fact is that when creating Corundum insulation, the developers were initially guided by the desire to eliminate heat loss in all three main directions. And you probably know these directions.
Heat loss building structures most often occur due to:
- Heat transfer;
- Convection;
- Radiation (even if it costs).
Heat transfer is dampened by most standard insulation materials. But at what cost? To level out the temperature difference, a person has to use bulky insulation with a thickness of 5 cm.
In this case, it must be laid on glue or in a special frame, and then covered again. Liquid thermal insulation performs the same functions, only its structure is tens of times denser, and its thermal conductivity is almost zero.
That is, when finishing the walls, the applied liquid will also prevent the air from exchanging temperature with their insides, but at the same time, an ultra-thin film acts as protection.
Convection is the transfer of heat from object to object. An extremely controversial method, because in ordinary construction it plays practically no role.
However, even this point can be completely eliminated by the liquid ceramic heat-insulating material Corundum.
But with radiation things are much better. Thermal radiation standard insulation materials are not able to extinguish (for example, ineffective).
That is, they can only transfer the radiation onto themselves, but a certain amount of it will still reach the surface of the walls. Meanwhile, radiation comes from all warm objects, especially from heaters.
For additional protection I had to combine regular insulation with foil. The foil reflected the waves, and the insulation did its usual tasks.
But liquid thermal insulation Corundum repels radiation by almost 90%. The residues are simply extinguished and dispersed close to the surface of the walls.
The result is a situation where all three main consumable items are removed by just one ultra-thin protective film. Surprisingly, customer reviews are also completely unanimous. Corundum insulation really works and does its job well.
1.3 Pros and cons
When selecting thermal insulation, it is important to pay attention to all parameters. They take into account technical characteristics, reviews and even consumption. However, first of all you need to look at the properties of the insulation. Why is it good, and why, on the contrary, does it repulse you?
The developers eat their bread for a reason. Corundum insulation has a huge list of advantages and a minimum of disadvantages. So let's look at them in more detail.
Main advantages:
- Can be applied to walls, floors, load-bearing structures, roofing, pipes, etc.
- The work is done with your own hands; improvised means will do.
- Dries quickly.
- A thin protective layer replaces up to 5 cm of standard insulation.
- Not exposed to external influences.
- Not afraid of moisture.
- Does not respond to temperature changes.
- Non-flammable.
- An elementary method of application as in the case with.
And this is not the whole list. Full characteristics can be assessed only after you have the instructions and certificates for Corundum thermal insulation in your hands. But even from this it follows that the material is extremely useful.
Just look at the fact that it can be applied with a regular brush. That is, any structure that can be reached can be processed.
Now remember the standard insulation processes. How much time does it take to decorate one column with mineral wool? And what can we say about the surface of the walls, which are surrounded big amount pipes?
While Corundum insulation will not cause you such problems. All you need to do is stir it and apply it to the wall. It is not surprising that the reviews about it are all positive.
Main disadvantages:
- Quite a high price.
- Serious expense.
As for the shortcomings, they are quite trivial. Like any innovative material, Corundum insulation is expensive. These are already production costs.
The second point, which partially overlaps with the first, is the serious waste of paint. Corundum must be applied in several layers. Accordingly, the consumption of such material will be very serious.
It is advisable to apply at least 4-5 layers to the surface of external walls. This is the only way to create high quality insulation and be sure that it will not crack or peel off.
2 Types and differences
Corundum insulation comes in several varieties. Each of them has its own technical nuances.
There is Corundum insulation:
- Classic;
- Facade, Facade-Lotus;
- Anticorrosive;
- Winter;
- Fire protection.
Liquid thermal insulation Corundum Classic – standard option, which is used almost everywhere. Thermal paint is easy to apply, dries quickly and has good strength parameters.
Thermal insulation Corundum Facade is intended for exterior finishing walls The Facade-Lotos sample is the front, second level of insulation. Apply for added protection.
Anticorrosion model – insulation with enhanced anti-corrosion properties, ideal for protecting wood.
The Winter model differs only in the possibility of application at sub-zero temperatures.
Well, the last option is paint, which swells upon contact with fire, protecting the structure from fire.
