The rise in prices for heating, electricity, gas and solid fuels forces us to reconsider the attitude towards saving and conserving heat. New technologies for facade insulation make it possible to quickly and efficiently achieve results, and along with the introduction of energy-saving heating equipment, this is the very first and inexpensive step towards saving.

Wall insulation of residential and utility buildings is not a novelty. For this, natural resources were widely used in ancient times. Mostly straw was used, from which mats were knitted and the walls of a barn or barn were insulated with them. For houses, chopped straw was added to the clay, which was used to plaster the walls made of wooden beams from the outside. Often, in order to reduce the thermal conductivity of the layer of external plaster and make it stronger, horse manure was added to it, in addition to straw.

Today, outdated methods have been replaced by modern, effective insulation based on minerals and polymers. Despite the cardinal changes in the field of heat-insulating materials, gas remains the main element of all heat-insulating materials, filling the porous structure of any heat-insulator.

Modern thermal insulation

For the first time, scientists began to closely study and develop effective heat insulators with the development of aviation, communications and refrigeration technology. In the construction industry, for a long time, expanded clay concrete and foam concrete remained the main protection against the cold. Glass wool was the first insulation material successfully used to insulate buildings, heating mains, refrigerators and airplanes. Many other materials have appeared today. Each has its own characteristic advantages that determine their area of ​​application.

Each thermal insulation material is produced in various modifications adapted for a specific use.

This is a kind of mineral insulation. Glass wool was made from sand, soda, dolomite, limestone and borax, and in modern production they use mainly recyclable materials - cullet. Glass wool, which is still considered quite effective and has a wide range of applications, is used to make mats and slabs of various rigidity.

The disadvantage of glass wool is working with it. Thin, almost invisible fibers fly in the air when styled and cause severe irritation when inhaled or in contact with the skin. Working with this insulation requires special training and the use of personal protective equipment.

This is a new generation of mineral insulation, which, together with the function of thermal insulation, is an excellent sound insulator. Stone wool is produced from a natural fossil - gabbro-basalt rock. It is also called basalt insulation. The range of modifications is subdivided into rolled insulation, plates and shaped (cylinders, segments, etc.). For its intended purpose, it is used to insulate protective structures, roofs, ceilings, pipes and boiler equipment.

Due to the resistance of basalt materials to high temperatures, it is also used as fire protection. Basalt insulation is often produced with additional additives.

Expanded polystyrene is one of the most used materials due to its relatively low cost. Along with excellent thermal insulation performance, foam plastic has a number of disadvantages. In addition, at first, its application did not have a clear definition and regulations, which gave rise to a lot of rumors and contradictions. Indeed, at the beginning of the second half of the XX century. Styrofoam was mainly used as packaging, so there was little concern about health safety. Low-quality foam could easily ignite, and when heated, release styrene and other toxins.

Modern polystyrene insulation in the form of plates, regulated by GOST 15588-86, is absolutely safe. They are made of high-quality stabilized polystyrene with the addition of a flame retardant, which makes the material self-extinguishing. In this case, the foam is susceptible to aging under the influence of sunlight. In order for the insulation to last a long time, the foam layer must be covered with a facing element (plaster, primer, paint, etc.). On the basis of polystyrene, plates of various thicknesses, sizes and rigidity are produced.

Safe foam is used to produce packaging containers for food that are in direct contact with the product. These products have permits and conclusions of the expertise of the sanitary services.

Izolon is a foamed polyethylene produced in the form of a roll material for sound and heat insulation. Foil-clad isolon is also produced to reflect infrared radiation. Its heat-insulating properties are several times superior to polystyrene.

Izolon is more often used for internal thermal insulation of walls, partitions, ceilings, laying it under the facing material - plasterboard, lining, block house, etc. On its basis, heat-insulating wallpaper is also made.

Sprayed heat-insulating materials are, perhaps, the newest technologies for warming the facades of houses, which, in addition to high quality, are carried out in a short time. Polyurethane foam is obtained by mixing polysocyanate and polyol.

The process takes place directly at the place of insulation in special equipment during spraying. The foaming reaction takes place directly on the wall, forming a monolithic structure. The resulting layer prevents the penetration of heat, sound and moisture, is fireproof, resistant to natural aggressive influences, climatic cycles and fungal growth.

This direction was originally intended for space technologies, but eventually became available in construction. The secret is in the composition of the paint, or rather in its filler. These are microscopic spheres made of glass or ceramics, inside which there is a discharged space. The binder can be latex, acrylic, silicone, or combinations thereof.

A layer of paint of just 1 mm creates thermal protection comparable to a 2.5 cm thick mineral insulation.

These materials are cladding and thermal insulation at the same time. Their design and content may vary. For example, mineral plates, polystyrene foam, cellulose, polyurethane foam can act as a heat insulator, and decorative plaster, metal, metal-plastic, etc. can act as a front layer. The design can provide for connecting grooves or other mounting methods.

The greatest effect of thermal insulation is achieved if the thermal conductivity of the insulating layer is 1.2 times lower than that of the wall. This allows not only to exclude heat loss, but also to protect the wall from the destructive effects of climatic cycles.

Isolation methods

The most effective is external insulation. In this case, the walls are protected from negative external influences and perform the function of heat accumulation, which also affects the savings on heating. At the same time, internal insulation, in some cases, has a positive result.

For a country house, a summer residence where permanent residence is not provided and you need to warm up the room quickly only at the time of arrival, internal insulation has advantages. In winter, when the house is not in use or heated, the walls will still freeze through and it is quite difficult to warm them up. The inner "shirt" will quickly heat the air and prevent the walls from absorbing heat.

External insulation of the house contributes not only to saving heat in winter frosts, but also to maintaining coolness in summer heat.

Technologies

According to the technology of performing insulation, it can be divided into 4 ways. Some methods are provided for by the project during construction, others are used as modernization of an already residential building.

Wet insulation

The most common type of insulation for private and multi-storey buildings, offered by many construction companies. The technique consists in fixing the thermal insulation boards to the wall using dowels or anchors and then coating them with an adhesive with plastering. Due to the lightness of materials, the method is applicable to any walls and does not require a miscalculation of the bearing capacity of the structure.

Ventilated insulation

Usually used for private houses as a retrofit or planned for construction. A tile or roll heat-insulating material is mounted on the wall and covered with a windproof cloth. Then the lathing is installed and the facing material, for example, siding, is installed on it. The space between the insulation and the cladding must be ventilated to prevent condensation.

This method must initially be provided for by the project. It is suitable for houses with clinker cladding. The method consists in facing masonry with a gap from the load-bearing wall. It is in this formed well that the insulation is put in.

The main condition is the choice of insulation that must "breathe". Mineral wool slabs are the best choice.

Panel insulation

This is insulation with heat-insulating cladding panels. The method is often used in construction or renovation of buildings, but it is also suitable for any home. At the same time, facing in this way the walls of one apartment in a multi-storey building will cause an architectural imbalance, therefore it is better to use it immediately for the whole house as a whole. With the help of composite panels, you can create a respectable appearance of the building and usually such insulation is included in the project.

How to insulate your house so that it is comfortable in the most severe frosts? The range of heaters is huge today, and the more difficult it is to make a choice. "Trading company Sayf" presents - a novelty of the domestic market of insulating materials, which in a short time became popular both in Russia and abroad.

Shelter is a new generation home insulation, developed and introduced into production by the company's specialists. EcoStroy... The material is universal and can be used for heat and sound insulation of any surfaces, gaps, roof junctions and other complex structures.

Characteristics of Shelter insulation

The basis of the new material is the finest organic fiber. Its production is carried out on automated lines without the use of glue and other chemicals by bonding fibers (each of them three times thinner than a hair) with a directed stream of hot air.

This gives a guarantee of absolute safety and hypoallergenic eco-insulation. Shelter.

Another production innovation is 4D technology, which allows the new insulator to retain its shape for a long time. It is this property that makes it convenient to use and effective for thermal insulation of hard-to-reach places. But this is far from all that I am capable of. Shelter.

Advantages of Shelter EcoStroy insulation

Today, the new product line includes several varieties: EcoStroy Standard and Standard 25, as well as Light, Premium, Acoustic, Facade, Master, Mezhventsovy, Sauna. All of them are of high quality, versatility and durability.

2. Moisture resistance. The ability to absorb moisture is below 1%.


3. Fire safety. The material belongs to class G1, that is, it practically does not burn, does not emit corrosive toxic smoke under the influence of fire.


4. Water vapor permeability. The ability to pass air and not collect condensation on surfaces under a layer of insulation.


5. Biological and chemical resistance. Shelter is equally not afraid of acids, alkalis, rodents, insects, mold.


6. Durability. The service life of the material without loss of insulating qualities is up to 100 years. Can be reused after dismantling.


7. Convenience of transportation. Small specific gravity and ability to regain its shape after squeezing make Shelter easy to transport.

How to insulate a house with Shelter

Are you looking for a quality and inexpensive way to insulate your house? The best solution - Shelter EcoStroy... Yes, it is more expensive than mineral wool and other traditional insulators, but the result is much better. In addition, its installation does not require any special skills or tools.

1. For installation, a wooden or metal frame is required with a pitch of 58 cm, taking into account the width of the mat 60 cm.


2. The connection of the insulator elements to each other is carried out using a construction stapler.


3. When insulating facades and external walls (for example, log houses), a layer of vapor barrier is pre-laid with Shelter.


4. To insulate walls over 2.5 m high, an additional partition is arranged on the frame, and then the mats are firmly held between the profiles only due to their elasticity.


5. For a tighter hold, it is recommended to use adhesive tape for ether fibers.

Many homeowners are faced with the problem of house insulation, and, consequently, the choice of thermal insulation material. After all, a warm home is not only a comfortable stay, but also a decent saving on heating. Practical owners take a responsible approach to the choice of insulation. The most popular and affordable materials that can be purchased without problems at any hardware store, we have considered in previous articles.

And now let's dwell on the novelties of the modern market - innovative developments that confidently enter our lives.

Liquid heat insulators: KORUND, Izolat, Teplomett, Astratek and others

Liquid heaters in Russia are produced by several companies, so the trademarks have different names. But the essence of their action is the same, and the generalizing names are heat paint or liquid ceramic thermal insulation. Outwardly, it is a viscous white suspension with good adhesion to any type of surface. Liquid insulation is applied with a brush, roller or sprayed. The result is a thin, elastic, durable polymer coating that significantly reduces heat loss.


Heat paint reflects and scatters radiation, it is not harmed by UV rays, it is ideal for insulating structures with high temperatures. The composition of liquid heat insulators includes ceramic microspheres filled with rarefied air and an acrylic binder. In addition, flame retardant additives are added to this mixture to prevent corrosion and fungus formation.

The invention of thermal paint made it possible to obtain a long-sought set of properties: this heat insulator is lightweight, flexible, applied in a thin layer, stretches and is suitable for any surfaces.


Advantages:

• saves usable space;
• has a high heat-insulating ability;
• has a low weight;
• hides noise well;
• protects not only from cold, but also summer heat;
• easy to apply;
• safe for human health and does not harm the environment.

The heat paint can be used to insulate walls, floors and roofs. In addition, it is suitable for surfaces with complex geometries (slopes, pipes, valves, containers of various shapes). After painting the facades of buildings, you can make the subsequent finishing cladding, and after applying on the walls from the inside, you can glue the wallpaper.

The only disadvantage of liquid insulation is the price. But there are all the prerequisites that with the development and spread of the technology for its creation, heat paint will become more accessible.

Plastmigran

Plastmigran is a new material based on mineral wool and polystyrene dust. After mixing the components, the composition is placed in a perforated metal module, where it is blown with steam under high pressure. The absence of chemical additives ensures the environmental friendliness of the material. The plastic material is durable, waterproof and fire resistant.

Plastmigran is literally devoid of flaws. But due to the high cost of equipment for its production, it did not find widespread use. Outwardly, these are thin plates or molded products that are easy and convenient to assemble.


plastic.

Disadvantages:

• for better adhesion to the base, degreasing with special chemical compounds is required;
• high cost of production;
• shortage in the domestic market;
• high price.

Plastmigran is perhaps the most unfamiliar word for potential customers interested in thermal insulation materials. But many experts are confident that the future belongs to him.

Teplolen

This insulation is not so new, but we included it in the list of innovations in view of the fact that in our country few people are familiar with it, despite all its positive qualities. So what is lukewarm? This is an insulating material based on linen fiber.

Flax has long been known for its unique properties: linen clothes are warm in winter and not hot in summer. These abilities were taken into account when creating the heat pump. In order for the insulation to keep its shape, 15% of the thermo-bonding fiber is introduced into the flax fibers.


The material will surely interest people interested in creating an eco-friendly home. Installation is heat-insulated does not imply the creation of a vapor barrier, it perfectly regulates moisture exchange, and also has bactericidal properties, which is especially valuable when it comes to wooden buildings. It is mounted thermally similar to other fibrous insulation. And its price is comparable to the price of extruded polystyrene.


So, the advantages:

• environmental friendliness;
• good heat and sound insulation properties;
• providing a comfortable microclimate due to smooth changes in temperature and humidity;
• absence of painful microflora;
• simplicity and familiarity of installation;
• no shrinkage;
• durability.

Teplolen is very popular in Finland, there are three factories for its production. And in Russia, insulation has just begun to conquer the market, but a great future is already being predicted for it.

Modern variations of fiberboard: Green Board®

Many will say that fiberboard is not an innovation, but a well-forgotten old thing, because it was produced in Soviet times, and in the West it has long been known under the name WWCB slabs. But the material in question is an improved fiberboard based on wood fiber, liquid glass and Portland cement.

This insulation has a unique property: its temperature begins to change only 10 hours after the temperature changes from the outside. So, in the heat, the fibrolite will warm up only in the evening, while the mineral wool is about in a couple of hours.


Advantages:

• service life - 100 years;
• good heat and sound insulation qualities;
• resistance to decay, mold and fungal infections;
• moisture resistance;
• frost resistance;
• ease;
• ease of installation (you can drill, hammer in nails, saw);
• shape stability;
• hardly combustible;
• no harmful secretions.

Another undoubted advantage of the improved fiberboard is seismic resistance, which makes it very popular in Japan. The disadvantages include only the price, which is decently higher than the price of traditional material.

Vacuum insulation

The vacuum heat insulator was created for the needs of a space structure. Today it is the most effective insulation, but at the same time the most complex and expensive. It is a rectangular panel with a vacuum inside and foil lining.


Advantages:

• 100% efficient: the vacuum inside implies the inability to transfer both cold and heat!

Disadvantages:

• difficulties in isolating joints;
• fragility;
• impossibility of installation in hard-to-reach places;
• high cost.

The market of heat-insulating materials does not stand still, every now and then new insulation materials appear, the properties of which exceed the advantages of the previous generation insulators. We will follow the emergence of interesting new products!

The following article will discuss in detail the properties, scope and application features of modern new-generation heaters. As an example, and not for advertising purposes, the Polynor brand was chosen - a one-component polyurethane foam insulation, which is sold in standard aerosol cans. They can be freely purchased at almost any hardware store at a fairly reasonable price.

The specified spray can is completed with a special nozzle for uniform spraying of insulation on a vertical, horizontal or inclined surface, as well as a special angle nozzle for spraying on the ceiling, but it is not included in the kit and must be purchased separately. Also, to apply polyurethane insulation, you will need a conventional assembly gun.

With the approach of winter cold, many people begin to think about insulating their residential square meters, whether it be a ready-made place of residence or a new house under construction. This is especially important in regions with harsh climatic and weather conditions.

Today, new building materials regularly appear on the market that can quickly protect any structure from freezing and, in addition, from annoying noise, the source of which is inside or outside the building.

The same modern insulation consists of polyurethane foam, which is environmentally friendly, safe and harmless to humans, animals, the environment and nature. This insulation does not emit any hazardous substances, so it can be used in any premises without any restrictions and preconditions.

Insulation can be used both indoors and outside - on balconies, loggias, ceilings, roofs, in basements and in containers for various purposes - this type of insulation can be used everywhere.

This material is not afraid of moisture and is completely uninteresting for small domestic rodents. It is quite durable and can be guaranteed to last 50 years without losing its original characteristics. This is several times more than the familiar mineral wool, the service life of which is only 10 years, and then subject to strict adherence to the technological process of its laying. This polyurethane foam insulation can be applied without any preliminary preparation and completely independently.

Insulation application

It is enough just before applying it to shake the can, and its temperature should be in the range from 25 to 30 degrees Celsius. If the work is carried out in cool weather or in an unheated room in winter, it is necessary to preheat the cylinder by immersing it in warm water at the appropriate temperature.

Insulation can be applied with equal success on both horizontal and vertical surfaces.

A special nozzle creates a directed spray. The recommended application layer at a time is 50 mm. In this case, one canister is enough for 1.2 sq. m. If the thickness of the application of the insulation material is reduced to 30 mm, then the coverage area will increase to 2 square meters. m.

Any person can work on applying polyurethane foam insulation. Even a housewife or a young girl who has almost never dealt with construction work can handle it. The only thing that is required is to wear safety glasses.

It should be noted that the polyurethane foam insulation discussed here, after complete polymerization, becomes completely inert with respect to water, both of technical origin and atmospheric, as well as to air. Fungi and mold do not form on its surface and cannot develop.

The only limitation in its use is protection against ultraviolet radiation.

In conclusion, I still want to note that before applying any insulation, including polyurethane foam, the surface should be cleaned from dust, oil and fat deposits, as well as from a peeling layer, for example, from old peeling plaster or paint.
