Current and effective insulation – liquid thermal insulation

What is ceramic thermal insulation

Ceramic insulation can be applied with a compressor.

Liquid ceramic thermal insulation consists of two main components - ceramic vacuum spheres and a connecting polymer composition (mastic). In appearance and consistency it resembles thick paint. The initial color of the composition is white, but you can add a variety of colors. The size of the ceramic granules is very small, so much so that they are visually invisible.

It was invented as part of the space shuttle insulation program. Then the task was to develop an effective thermal insulation material that would have minimal weight. Every additional kilogram launched into orbit is a colossal expense, so the goals are very justified. Over time, the material became available for civil engineering.

Liquid ceramic thermal insulation can be applied in several ways:

• brush;
• roller;
• spray.

In the latter case, you need to dilute the paint with plain water. This is possible since the composition is made on an acrylic base, that is, it does not contain any solvents.

The thermal conductivity coefficient differs from different manufacturers, the lowest that could be found is 0.0012 W/m*C, but thermal conductivity is rarely indicated above 0.0025 W/m*C.

This insulation is not afraid of moisture, sunlight, is not blown by the wind and can withstand extremely high temperatures. Based on the stated characteristics, the ideal insulation is liquid ceramic thermal insulation. Reviews from those who have already tried this product are somewhat different from marketing ploys. We'll talk about this a little later.

The most popular manufacturers of insulation paint:

• Astratek;
• Corundum;
• Akterm.

Features of the composition

Ceramic liquid thermal insulation is practically no different in appearance from the acrylic paint we are used to.

Today, there are several types of insulating compounds, but almost all of them have the same structure:

• The basis of liquid ceramics is a water-acrylic mixture. It ensures uniform distribution of insulating components over the surface and helps to secure the thermal insulation.
• As additional components, various additives to improve the performance characteristics of the material. The most popular additives include artificial and natural rubbers, silicone, etc.
• The main component responsible for reducing heat loss by the treated surface is ceramic granules filled with highly rarefied air. The microscopic dimensions of the granules and the almost ideal spherical shape make it possible to apply the composition very thinly to the wall.

Material structure

Note! For high-quality varieties of liquid ceramic thermal insulation, subject to complete polymerization, the proportion of voids in the insulating layer is about 75-80%. This allows you to create an ultra-thin layer on the treated surface with a very high heat transfer resistance.

Advantages and disadvantages

Compared to traditional insulation, liquid heat insulator based on ceramic microspheres has a number of advantages:

• Firstly, when insulating a house from the outside, the useful volume of the room is not lost. A thin layer of paintable insulation cannot be compared with sheathing made of mineral wool or other porous materials, so for rooms with a small area, the use of this composition can be an excellent solution.

The principle of operation of thermal paint

• Secondly, the applied layer does not degrade over time. The guaranteed service life of a ceramic coating is up to 15 years , but with proper care (application of finishing and timely cleaning), this time can be at least doubled.
• Thirdly, the mass of the material is insignificant, due to which no additional load is created on the supporting structures. This advantage of the material is especially pronounced when finishing roofs.
• Another plus is the ease of surface treatment: liquid ceramics are applied no more difficult than ordinary paint, and therefore are excellent for insulating complex architectural forms and rooms with non-linear configurations.

Photo of the treated surface

Among other things, it is worth noting the compatibility of most compositions on the market with facade and interior paints, decorative plasters, etc. At the same time, no primer is required for finishing the ceramic layer!

Note! Insulation of pipelines, outbuildings, etc. can be carried out without decorative finishing - the aesthetic appearance of the coating after polymerization allows this.

When talking about the disadvantages of ceramic insulation, they most often mention the rather high cost of the material. However, if earlier, when only foreign brands were represented on the market, this was fair, today the situation has changed somewhat. Domestic brands, such as liquid ceramic thermal insulation coating Corundum, can be purchased at quite affordable prices.

Thermal paints – ultra-thin insulation materials

Based on the application technique, liquid thermal insulation materials are divided into ultra-thin paints and foam insulation. Next we will talk about the first option, which differs from competitive products in its simplicity and speed of application .

Composition of thermal insulation material

Liquid ceramic thermal insulation is similar in appearance to thick acrylic paint. The composition of most mixtures is the same; the structure of the material is dominated by:

1. Ceramic granules. The main component that helps reduce heat loss. The spherical granules are filled with rarefied air. Thanks to the minimal sizes of the components, the mixture is evenly distributed over the insulating surface . The heat insulator contains about 80% ceramic granules.
2. Binding base. A water-acrylic mixture with high adhesion rates to many building materials.
3. Additional components. Increases the thermal efficiency and performance of the paint. Manufacturers often use silicone, titanium dioxide, aluminosilicate microspheres, and latex additives. The components give the insulation the required water resistance and elasticity .

The effect of using thermal paint is achieved due to the large number of hollow microspheres - thermal energy losses are reduced due to normal convection. The thermal efficiency indicator of ultra-thin thermal insulation with a layer of 1.2 mm corresponds to the heat-saving ability of mineral wool of 5 cm.

Strengths of warm colors

Technical characteristics and application features allow us to talk about the following advantages of liquid thermal insulation:

1. The low thermal conductivity of the material (0.001-0.0015 W/sq. m*s) provides a good heat retention effect , while the insulating layer will be minimal.
2. Seamless coating. Sprayed insulation can boast of this advantage. When installing other materials, cold bridges are formed at the joints.
3. Environmentally friendly. Compositions for interior work are made absolutely safe and non-toxic.
4. Impossibility of dismantling. This plus is relevant when insulating country houses that are empty in winter. Attackers will not be able to remove the insulation.
5. Easy to apply. The technological process is simplified as much as possible and does not require expensive equipment or experience in construction.
6. Space saving. It is especially important for internal insulation of house walls.
7. Resistance to moisture, counteraction to the formation of microorganisms, the appearance of fungi and mold.
8. Wide operating temperature range. The coating can withstand numerous frosts and retains its physical properties at +220°C .
9. Excellent adhesion. Suitable for use on metal, wood, plastic, brick, etc.

Disadvantages of liquid insulation

Skeptics question the real thermal efficiency of the innovative insulation, saying that its capabilities are exaggerated. Some experts give their arguments and point out a number of shortcomings:

1. Inability to use inside the home. From an environmental point of view, there are no problems. However, after hardening, the paint creates a waterproof film on the surface - the dew point moves to the inside of the wall. Possible consequences: freezing of house structures, the appearance of fungus .
2. Actual thermal insulation performance is lower than the quality declared by the manufacturers. Skeptics claim that thermal paint will replace 5 cm of mineral wool only if 10 layers are applied. However, such consumption negates the feasibility of using liquid insulation, since its cost is considerable.
3. Short shelf life of the material. If the conditions are not met, then the thermal paint loses its qualities.

Scope of application of ceramic insulation

Where other insulation materials are powerless, ceramic thermal insulation will help.

Recently, ceramic thermal insulation has been used wherever possible, and a program for insulating facades is even supported at the state level. This insulation is suitable for:

• application to stone and concrete surfaces from the outside and inside;
• reducing heat loss from pipelines;
• protection of metal structures.

As you can see, liquid ceramic insulation is a universal product that is not applicable only to wood. The reason for this is the vapor barrier qualities of the material, and as you know, wood breathes and this process should not be disrupted.

In everyday life, this type of insulation is applied to internal walls; it can be used to cover a heating buffer tank (battery tank); even a bathtub covered with this insulation paint will retain heat longer. Also, if you use liquid ceramic insulation on the basement floor from the inside, you can solve three problems at once:

• insulation;
• waterproofing;
• vapor barrier.

In this case, the material is suitable as an auxiliary measure, since the main protection of the walls of the basement is located outside. This is a bitumen hydro-vapor barrier and extruded polystyrene foam as insulation. When ceramic insulation is used to reduce heat loss from communications or metal tanks, additional layers of thermal insulation will also not hurt.

Buying tips

The significant price of ceramic insulating compounds is the reason why you should be very careful when purchasing material in a store or on the construction market.

Instructions that allow you to avoid making mistakes and buy a high-quality heat insulator are given below:

• The first thing you should pay attention to is the density of the mixture. High-quality insulation materials are characterized by an indicator of no more than 0.6 kg per 1 liter of product. Thus, a standard ten-liter bucket should not weigh more than 7.5 kg. Otherwise, we can safely say that the thermal insulation properties of the paint will be low.

"Korund" is one of the most popular brands

• Looking at the container with the material “through the light”, you can see its delamination. Typically, the lighter fraction containing ceramic spheres ends up on top. So the thicker the top layer, the more effectively the paint mixture will retain heat.
• The third test is to determine the structure of the mixture itself. Take some paint and rub it between your fingers. Microgranules should be felt as small roughness, and their absence should be considered a reason to choose a different brand.

It is these micrograins that can be felt with your fingertips.

It is also worth paying attention to the color of the paint. The vast majority of brands of liquid ceramic insulation are produced in white, so a gray or yellowish tint is evidence of violations in the manufacturing technology. Naturally, this does not apply to compositions into which a color pigment has previously been introduced.

Surface application

Ceramic thermal paint is quite easily applied to surfaces made of a wide variety of materials.

So if you decide to do the painting insulation work yourself, you just need to follow some recommendations:

• The wall to be painted must be cleaned of dust and debris. We open up the gaps and cracks and fill them with repair compound.
• We clean concrete slabs from “cement laitance”.
• Immediately before painting, we treat the wall with a sandblasting machine, an abrasive wheel or a wire brush.
• Ferrous metal surfaces are dusted and degreased. Non-ferrous metals require preliminary removal of the gloss and application of a primer such as VL-023 or VL-02.
• Mix the ceramic composition immediately before applying it to the wall. As a rule, mixing is carried out manually.

Note! To work with large volumes, the use of construction mixers is allowed, and the rotation speed should not exceed 150-200 rpm. At a higher speed of movement of the nozzle, destruction of ceramic granules and a decrease in heat-saving characteristics is possible.

• Mixing time by hand is from 10 to 15 minutes, with a mixer - 3-8 minutes.
• Some formulations require adding water before starting work. The volume of liquid depends on the brand of material and the purpose of using the insulation. The required proportions are usually indicated on the packaging, and can also be found on the manufacturer’s website.

Applying the composition with a brush

What types of insulation are there?

Most often in stores there are two main representatives of liquid insulation: ultra-thin, which in consistency resemble paint, and foam.

The first option includes:

• Hollow aluminosilicate microspheres. They are formed from flaring coal, and the temperature must be very high;
• Latex component;
• Special dye E171, which gives a white color;
• Acrylic.

Thanks to all the components, the output is a substance that has quality parameters, for example:

• Ensuring an acceptable climate in summer and winter;
• Good reliability indicator, high resistance to deformation;
• Neutral to sunlight, therefore retains its color throughout the entire operational period;
• Does not spread when applied to the surface.

Foam insulation can be: liquid foam, which is familiar to most users, and penoizol (foamed polyethylene).

The first option shows reliability when exposed to corrosion, mice and rats. In addition to impressive thermal insulation qualities, this material can provide the owner with good sound insulation. It is used in cases where the voids formed are too large.

Foamed polyethylene, like the previous option, can be used as a void filler. For example, after installing windows, doors or during the construction of frame structures. The material has excellent reliability, strength and durability, which makes it in demand for most builders. To apply it, no thorough cleaning of the surface is required; you only need to remove traces of dirt and dust.

The main composition of such insulation includes the following components:

• Water;
• Urea-formaldehyde resins;
• Phosphoric acid;
• A special device for foam formation.

It is important to know that most of the elements present in the composition are not safe for the body. So, when carrying out work, it is important to pay attention to the choice of personal protective equipment. This way, the user will avoid getting substances into the respiratory tract and eyes.

Liquid thermal insulator TC Ceramic: specifics

Products of this brand are sold in the form of a suspension

containing acrylic polymer materials, artificial rubber and various pigments. Additionally, the composition includes ceramic microcavities and silicone spheres. The material is applied to various types of surfaces:

• brickwork;
• glass;
• plastic;
• metal;
• tree, etc.

The application method is similar to the method of treating surfaces with paint - use a roller, brush or spray.

According to the manufacturer, when treating external surfaces, the coating retains its service properties for 10 years, while when developing a layer of thermal insulation in the middle of the room, this period becomes 2.5 times longer.

The material can be used to thermally insulate both horizontal surfaces (floor, ceiling) and vertical surfaces (roof, walls, facade, etc.). The material will protect against temperature fluctuations, ultraviolet rays and moisture.

Types of insulation with liquid thermal insulation materials

Today there are 3 types of liquid insulation on sale, which are applicable for insulating walls inside and outside the room, as well as for insulating ventilation pipes, roofs, and attics.

1. The first group contains ceramics. Before application, the liquid looks like acrylic white paint.
2. The second group is liquid polystyrene foam or penoizol. Polymer composition applied using equipment.
3. The third group is ecowool. The composition contains natural fibers. After application to the surface, ecowool has good technical characteristics.

Before applying the insulation, the surface is prepared: dust, dirt are removed, and cracks are reinforced. One of the insulation materials can get into the gap, thereby stopping the destruction. And also sealing joints.

A clean, prepared surface is the key to good adhesion to the heat insulator and a long service life.

Ceramic insulation

Liquid heat insulator based on ceramic filler is one of the most popular for insulating walls of a room and beyond. It has adhesion to brick, concrete, wood, plastic, and metal surfaces. Does not lose technical characteristics.

The heat insulator is used on plastic and drywall to increase their strength. It is safe for health and fireproof. After insulation, finishing materials are used.

5. When insulating a house from the outside, siding or other finishing is required for complete insulation.

Expanded polystyrene insulation

Liquid polystyrene foam is foam (penoizol).
It hardens when opened within 2-3 hours. Because of the liquid, it fills cracks in the walls. The material does not expand like polyurethane foam, so it is used for gluing panels, replacing fasteners.

Liquid foam is sold in cylinders. If it is necessary to use it for insulation of walls and other structures, equipment is used.

Scope of application:

1. Insulation of floors, attics, attic floors - horizontal planes.
2. Suitable for insulating walls made of brick and concrete, as well as wooden floors.
3. Filling voids between rafters, insulating inclined roof planes.
4. Insulation of underground space, basements, garages.

Insulation is used in the cracks of wooden windows and other narrow spaces.

Often this heat insulator is used as glue.

Manufacturers

Penoizol is produced in certain proportions by both individuals and construction companies.
For production you need: foaming agent, ABSA acid grade A, resin, equipment. The components are easy to purchase from factories. Equipment for installing foam is expensive. One of them is “Leader 20”. All components of the insulation are mixed in it, and the material is also used to apply the material to the surface.

The equipment package includes a housing. It contains pumps, pressure gauges, and an electronic control unit.

Advantages and disadvantages

Liquid foam has advantages:

1. Thermal insulation indicators. 10 cm of suspension is equal to 30 cm of ordinary foam.
2. The temperature range at which the insulation does not lose its technical characteristics is -70 +200 0C.
3. It is possible to use a small amount of insulation. These are small cylinders that are sold in hardware stores.
4. The only insulation used to fill small voids and cracks.
5. Liquid insulation is used as an adhesive and as a heat insulator. It acts as a replacement for fasteners.
6. The insulation is resistant to mechanical stress, and also does not harbor rodents or insects.
7. Does not rot or become moldy.
8. Does not burn. Good adhesion.
9. The lifespan of the installed insulation on the surface is 78 years.
10. It is soundproofed.

Flaws:

1. Can absorb water. To solve this problem, it is necessary to add additional elements to the composition.
2. Unpleasant odor during installation.

When the foam hardens, the smell disappears.

Adviсe

To use penoizol as insulation for walls, basements, attics, and roofs, you must call a team of craftsmen. They have equipment that applies the material to the surface.

For small installation work, small cylinders are used. They work with them like polyurethane foam without any special skills.

Ecowool

The insulation consists of 80% recycled cellulose and 20% minerals, boric acid. Wood fibers, waste paper, and cardboard are used for insulation.

The material keeps the room warm. The applied composition has a smooth surface without “cold bridges”. Installation is carried out using equipment. Used for insulation of floors, places where condensation appears from high humidity.

Manufacturers

Manufacturers of ecowool:

1. Greenfiber. The first place in the production of material. The use of new technologies and equipment results in the production of high quality insulation. It has thermal insulation, noise absorption, and water-repellent properties.
2. Ecovilla. A manufacturer whose products are known all over the world as high-quality materials with a long shelf life and good technical performance.
3. Termex. All manufactured products are environmentally friendly and have a long service life.

In addition to imported companies, there are also domestic ones:

1. Ecovata Extra LLC. The heat insulator is used for insulation of residential premises and industrial buildings.
2. "Equator". The cotton wool production process is automated. New European equipment is used for this. The material differs from others in its high technical performance.

Ecowool is suitable for insulating buildings due to its environmental friendliness.

Advantages and disadvantages

Positive aspects of the material:

• sound insulation indicators;
• 28-65 kg of cotton wool is needed per 1 m3. This is relatively little compared to other formulations;
• health safety;
• There are no seams or cracks during installation.

There are also disadvantages:

• installation requires equipment and a team of craftsmen;
• need a frame;
• has shrinkage;
• insulation can smolder when heated.

Adviсe

When buying insulation yourself, you need to make sure that the packaging is intact and transparent. There should be no sand at the bottom.

RE-THERM products: what they are and how they work

To create a good layer of thermal insulation, products from the RE-THERM company are suitable. The manufacturer speaks of the material’s ability to protect surfaces of various types , also with non-traditional relief solutions. Thermal insulation

RE-THERM is fireproof, does not contain chemically hazardous substances, is considered a fully environmentally friendly material, but what is very important is that it exhibits the ability to have low thermal conductivity.

Heat insulators are available for purchase in the form of a suspension in several types to solve various types of problems:

• Standard;
• Fire retardant;
• Inhibitor;
• Ruber;
• Antifreeze;
• Vertical.

The standard is suitable for different types of surfaces; it is used for wall insulation outside and inside the house. The fire retardant was developed for rooms and structures with a risk of fire; it differs in fire resistance. The inhibitor is designated by the manufacturer as an insulating material for metal surfaces that prevents rust.

In transport, and also in systems with a risk of vibration, it is reasonable to use a heat insulator in liquid form of the Ruber brand with very high levels of flexibility. But for thermal insulation of surfaces exposed to low temperatures, thermal insulation

Antifreeze that can withstand temperatures up to? 40 degrees.

To insulate vertical surfaces while preventing material from dripping, the manufacturer has developed a specialized version of the thermal insulation with very high viscosity called Vertical.

Thermal insulation Teplomett - easy to apply and comfortable to use

Another worthy of attention insulating surface material according to today’s scheme is Teplomett products. Also, as in previous cases, the heat insulator is characterized by good thermal and moisture protection characteristics, durability, and the ability to interact with surfaces of different types

.

Thermal insulation

Teplomett is invulnerable to temperature fluctuations, damage from mechanical factors, and does not contain harmful substances.

Insulation with material does not take into account the use of an additional layer for protection due to its ability to not allow moisture to pass through. An added bonus is the multi-colored pigments included in the composition, which allow you to create a coating with a beautiful appearance. The material can be applied using one of the standard methods: brush, roller or spray.

Alfatek - liquid insulation for years

It is for many years to come that the manufacturer proposes to insulate surfaces with Alfatek liquid insulation. Just like its analogues, the material consists of many components, including foam glass and acrylic. Thermal insulation in this form is completely safe, does not contain harmful volatile compounds, is resistant to open flames, and does not lose its basic functionality at temperatures from −60 to +260 degrees Celsius.

According to the manufacturer, the service life of Alfatek liquid insulation is up to 20 years. It is used to protect communication systems, residential and industrial buildings from cold (walls, ceilings, roofs and floors are insulated), air conditioning systems, pipelines, etc.

Thermal insulation Isollat ​​- special insulation of a new generation

The manufacturer recommends using thermal insulation within the temperature range from −60 to +500 degrees Celsius, with the possibility of increasing the extreme mark to +600 degrees in critical situations. It is precisely this wide range of temperatures permissible for operation that distinguishes the insulation from its analogues.

The color of thermal insulation in the basic version is white; at the buyer’s request, color pigments of any shade can be added to the composition.

The composition includes hollow ceramic capsules with rarefied air, due to which it is possible to take the effectiveness of the material to a new level.

Thermal insulation is available in six options:

• Izollat-01 is suitable for insulating walls and roofs, both inside and outside, including in buildings with many years of service.
• Isollat-02 is the base material for insulating surfaces for use in temperatures ranging from −60 to +170 degrees.
• Isollat-03 - contains fire retardant additives that prevent ignition.
• Isollat-04 is the only one in the whole world capable of withstanding temperatures up to +500 degrees and up to +600 degrees at critical moments. Suitable as insulation for industrial equipment.
• Isollat-05 - suitable for insulating metal surfaces susceptible to corrosion. Can be used at temperatures up to +160 degrees with additional treatment with silicone varnish.
• Isollat-nano - used for insulation of external walls, has the ability to self-clean.

The latter option is rarely available on store shelves, as it is offered to the buyer on order.

Liquid insulation Corundum - performance characteristics

The production of ultra-thin insulation Corundum is carried out by NPO Fulleren LLC. In the domestic market, products under this brand are in particular demand, primarily due to the proliferation of dealership centers.

Thermal insulation suspension is suitable for insulating facades, roofs, walls, pipelines, tanks and other objects, systems and structures. The material is available in several versions:

1. Classic - for finishing surfaces of any type with intended use in the temperature range from −60 to +200 degrees Celsius (a critical increase in temperature up to +260 degrees is possible).
2. Anticorrosive - just like its analogues, it is used to insulate and protect surfaces from corrosion, and exhibits increased resistance to UV rays and chemicals.
3. Winter - coating for finishing surfaces at sub-zero temperatures down to −20 degrees. The composition includes foam glass granules. Samples available for testing.
4. Facade - insulation for finishing concrete external surfaces.

The cost of the material depends on the brand and purpose; the material is applied in the usual way: with a roller, brush or spray.

Which company is better for choosing liquid insulation?
