The topic of modern thermal insulation materials, both imported and domestically produced, continues to interest readers, because thanks to these materials it is possible not only to reduce home heating costs, but also to significantly reduce the cost of building construction. A leading specialist advises.

What are the advantages of URSA and Izover heat insulators?

I had to work with Russian mineral wool. Despite the special protective suit and respirator, particles of material got onto the body and into the lungs, causing very unpleasant sensations. People who constantly work with her often received dangerous occupational diseases. Another drawback is that this heat insulator collapses quite quickly in the wall and sags, resulting in upper part the wall loses its thermal insulation, while in the lower part it deteriorates significantly. Thermal insulation materials, which we offer, are completely environmentally friendly and even pleasant to the touch, durable, have better insulating properties and, finally, are cheaper than those made in Kstovo or Vyksa.

- Is there any difference between URSA and Izover?

If it exists, it is very conditional. Both materials are fiberglass, both have the same technical characteristics, even appearance they are so similar that not every specialist will be able to distinguish them when unpacked. By the way, their packaging is the same - shrink film, which reduces the transport volume by up to 35 percent of the working volume, which allows three cubic meter packages of this heat insulator to be placed in ordinary Zhiguli cars.

But we bring Izover from Finland, and URSA is manufactured in the city of Chudovo, Novgorod region. Many consumers prefer imported material (it is a little more expensive), although the Germans, the owners of the Chudovsky plant, strictly ensure that the material produced here is no different from that produced in their homeland or at the concern’s factories in other countries of the world. Another question is that the capacity of the Chudovsky plant is not enough for the whole of Russia and very often people are simply forced to use imports... - Where are these heat-insulating materials used and what are their varieties? - They differ among themselves in rigidity - from M-15 to P-75 (the stiffer the material, the higher the wall it can be installed in, but the more expensive it is), in thickness - from 50 to 140 mm. Can be applied to one or both sides of the material polyethylene film, foil or kraft paper. Since they are classified as non-flammable and have excellent thermal insulation properties (their thermal conductivity coefficient is only 0.04-0.05 kcal/mhC, which means that 18 cm of heat insulation protects the house from the cold in the same way as a two-meter brickwork), are environmentally friendly, they can be used for thermal insulation and roofs, and interfloor ceilings, and external walls, and floors, and basements, and internal partitions, and heating pipes. In short, they are universal. Moreover, such materials are very convenient to work with. Install interior partition- place between the wooden beam or metal profile on which the plasterboard or gypsum board is attached, a medium-hard insulation board with a thickness of only 50 millimeters. Such a partition will provide better heat and noise insulation than one laid out with one and a half bricks. But it doesn’t need to be plastered. The labor costs for its construction are incomparably less. Due to its light weight, it can be placed almost anywhere, and the cost of the materials themselves is lower...

This is probably the main advantage of modern thermal insulation materials:

security best quality at a lower cost. For example, when building a boundary wall, you can make it out of brick. Or you can use it to build only the inner, load-bearing part of the wall with a thickness of only 175 mm (half a brick), attach an 80-120 mm layer of thermal insulation to it and lay it with any facade material (Besser blocks, facing brick, siding, boards). The price will be much cheaper, but the comfort of housing and its heat protection will be better. And there is no need to be afraid of these building structures - this is how they are built in many countries of the world, where they live much better than in Russia. I've met more economical solutions. It is used as a load-bearing part of the structure wooden beam, between which a heat insulator is attached, the inner part of the wall is sheathed with GVP, and the outer part is lined with tongue and groove. Externally, such houses resemble garden ones, but they are warm and comfortable.

You talked about the advantages of the URSA and Izover materials, but did not mention anything about their disadvantages.

Flaws? Perhaps only one. They don't like moisture. When ingested, they partially lose their properties. Therefore, they cannot be wetted, and condensation should not accumulate on them inside building structures. For this purpose, special ventilated structures have been developed or polyethylene film, aluminum foil or kraft paper are used as vapor barriers.

Man has always strived to improve his living conditions, an integral part of which is the warmth and comfort of his home. Thanks to heating systems and for air conditioners, this possibility has become real, however, with poor thermal insulation, these devices will work inefficiently and consume a lot of energy. Therefore, it is so important to properly insulate your home, using only high-quality insulation material that will last for many years.

Mineral wool can be considered one of them; it is used long time in insulation of house walls, partitions, pipes, etc.

Mineral wool has become widespread due to its performance properties, among which the most significant are:

• non-flammability - the material itself does not burn and prevents the spread of flame if a fire occurs
• minimal shrinkage - throughout the entire service life, mineral wool slabs practically do not shrink, which ensures uniform insulation of the building.
• high thermal insulation properties.
• low sound transmission capacity.
• resistance to aggressive environments– under the influence of various substances, the properties of the material do not deteriorate.

Manufacturers of mineral wool

Leaders in mineral production thermal insulation wool on domestic market The following manufacturers are:

1. Concern Rockwool produces mineral wool intended for any structures and their elements, used both in industry and in everyday life. Mineral wool is made mainly from basalt.
2. The Izover company is one of the leading leaders in the production of fiberglass-based mineral wool and stone fiber.
3. Ursa is a manufacturer of fiberglass thermal insulation using eco-technology.
4. Knauf is a leading company in production and sales building materials.
5. TechnoNIKOL company – Russian manufacturer high quality insulation.

Minwata Rockwool

The main feature of the laboratory production of Rockwool mineral wool is that it is identical to natural conditions during a volcanic eruption.

This effect has a positive effect on the quality of the building material - the arrangement of the fibers is chaotic, due to which the following properties are achieved:

• combustion resistance– at temperatures up to 1000 C they do not even melt,
• excellent thermal insulation properties– up to 0.046 W/m K.
• vapor tightness
• not affected by water
• high sound insulation
• increased resistance to mechanical stress.

The Rockwool brand became widespread among construction companies and private consumers of the domestic market due to perfect fire safety, good hygroscopicity and sound insulation and relatively low cost. Prices from different suppliers may vary widely, because... Some sellers offer immediate installation work and delivery to the site.

There are also various types of this insulation material, for example, the price of Rockwool Light Butts starts at 1,873 rubles for 1000x600x50mm slabs, and some facade varieties of mineral wool can reach 7,000 rubles for the same volume.

Izover insulation

The production of Izover insulation is carried out using TEL technology from high-quality fiberglass.
The product obtained in this way has the following characteristics:

1. Thermal conductivity is about 0.041 V/m K - an indicator that provides excellent thermal insulation. Over time, this figure does not increase, keeping the room temperature constant over a long period.
2. High level sound insulation thanks to small air gaps between the fibers, it will not only provide protection from noise on the street, but also isolate the rooms inside the building from each other.
3. Fire safety. All Izover mineral wool is not susceptible to fire and meets fire safety requirements. Therefore, its installation can be carried out in buildings of any type.
4. Vapor permeability is 0.5 mg/mhPa - an excellent indicator for this type of insulation material, however, with an increase in humidity by 1%, thermal insulation decreases by 10%. In order to prevent the mineral wool from getting wet, you should leave a gap between the insulation and the wall for better air ventilation.
5. Service life. The manufacturer claims a lifespan of 50 years without deterioration in quality; this information is confirmed by reviews from owners who have been using this material for several years.
6. Health safety. It is believed that some types of mineral wool negatively affect human health, but scientists have proven that Izover thermal insulation does not harm human health.
7. Weight of Izover slabs quite low, so they are widely used for insulating buildings with weak structures.
8. Form of production. Izover mineral wool is produced in rolls of 16-20 cubic meters. meters and slabs, single-layer, 5-10 cm thick and multi-layer, the thickness of each layer is 5 cm. The cutting of slabs can be very diverse.

Minvata Ursa

URSA mineral wool is intended for insulating not only walls and roofs, but can also be used to insulate ventilation ducts and other communications. In addition, this thermal insulation material has high level noise absorption and long-term operation without loss of quality. All these technical specifications led to the widespread use of Ursa mineral wool in industrial construction and private use.

Ursa mineral wool is based on fiberglass, which has good thermal insulation properties due to the elasticity and strength of the fibers, between which air layers are formed. Thermal conductivity coefficient of this material ranges from 0.035 to 0.044 W/mK, which is an excellent indicator for this type of insulation.

Depending on the type of mineral wool, sound insulation can be class “A” and class “B”. If, along with insulation, it is necessary to isolate the room from extraneous sounds, class “A” building materials are used, which can replace a soundproofing partition. Regardless of the type, all Ursa mineral wool is environmentally friendly and undergoes thorough testing at the production stage. Ursa pays special attention to human safety - it has achieved excellent results, for example, the content of harmful volatile compounds in Ursa mineral wool is 10-15 times less than in domestic or European analogues.

From a fire safety point of view, Ursa mineral wool is completely non-flammable due to the use of quartz sand in its composition. The material can withstand extreme temperatures and is able to prevent fire from spreading beyond its boundaries. As for the service life, mineral wool can be used for 50 years without losing its original properties. It is biologically stable, i.e. various rodents, microorganisms and fungi will not spread in such conditions.

Minvata Knauf

Mineral wool brand Knauf, made in Germany are famous high quality and safety for human health. This is due to the fact that, unlike many of its competitors, Knauf mineral wool does not contain phenol-formaldehyde resins, which contain harmful substances.

To appreciate the properties of this building material, let’s consider its technical characteristics using the example of TeploKnauf insulation for houses and cottages in rolls:

1. Thermal conductivity– 0.037 W/mK
2. Noise protection– 45 W
3. Flammability– not flammable
4. Dimensions— 6148x1220x50
5. Volume of one package– 0.75 sq.m.

Knauf insulation has a number of advantages that are so valued construction organizations and private individuals:
- a low coefficient of thermal conductivity allows you to maintain heat in the apartment even in the most severe frosts.
- Knauf mineral wool was widely used in houses located near tram tracks and highways.

This is due to the fact that it has excellent soundproofing properties and provides comfort and silence in the house.

• not susceptible to rodents and fungal growths.
• fireproof; even if a fire occurs, this substance will prevent further spread of the flame.
• ease of transformation - mineral wool can be compressed to a size several times smaller than its actual size, thanks to this property it can be transported in large quantities.
• the absence of shrinkage throughout the entire period of operation will eliminate the need for repairs and additional installation of mineral wool.
• light weight, making it easy to install
• safety for human health

The only drawback of Knauf insulation can be considered its price; it is higher than that of many competitors, but in many technical indicators Knauf surpasses them. Most cheap option Knife mineral wool will cost the buyer 1,200 rubles per roll of 18 square meters, 50mm thick.

Minvata TechnoNIKOL

TechnoNIKOL is domestic manufacturer insulation materials included in the top five the best companies Europe for the production of these products. TechnoNIKOL mineral wool is made of basalt fibers, which are characterized by high environmental friendliness and thermal insulation properties. This material is used for insulation of multi-storey buildings in industrial scale, and in private housing construction.

The most common types of mineral wool produced by TechnoNIKOL are presented below:

1. Rocklight– basalt slabs with a low content of phenol in resins, due to which this material has increased safety and environmental friendliness. The main area of ​​application is insulation of private houses. It can be used to isolate horizontal, vertical and angled surfaces. The load on the structures is small, so they may not have high strength, which expands the scope of their application.
2. Heatroll- a material consisting of long rolls of cotton wool that have improved sound insulation properties. They are most widely used in the insulation of roof slopes, floors between floors and attic spaces.
3. Technoacoustic– designed primarily for sound insulation, in addition it has good heat-saving properties. It is presented in the form of cotton wool, made from specially arranged basalt fibers, due to which one layer of this material can prevent the penetration of sound up to 60 dB. This type of insulation is mainly used in interior decoration buildings - partitions between walls, ceilings, attics.
4. Technoblock– are produced in the form of low phenolic flat slabs that are resistant to combustion, noise and heat insulation, and are also not susceptible to moisture. They are used in most cases for insulating layered storage facilities and frame buildings.

The main characteristics of TechnoNIKOL mineral wool: thermal conductivity 0.035-0.039 W/mS, vapor permeability 0.3 mg/mhPa, water absorption 1.5-2%, Density 25-50%, compressibility 8-55%.
Prices for TechnoNIKOL mineral wool are quite low and easily compete with foreign analogues. Thus, Rocklight slabs can be purchased for only $38 per cubic meter.

Having examined the main types of mineral wool offered for sale, you can make a choice in favor of one manufacturer or another. Depending on the scope of use, the conditions, price and other nuances, you should buy a certain brand of mineral wool. Not only the comfort and warmth of your home, but also the safety of the whole family will depend on how responsibly you take this matter.

Good roof insulation is valuable not only in winter - it also saves you from the summer heat and cuts out unnecessary noise from outside. The range of insulating materials is large, but choose best option difficult for an inexperienced person. Too many nuances, unconvincing advertising promises and conflicting reviews. Let's figure out what it offers us modern market, and how you can insulate an attic, a regular roof or an attic.

It is more profitable for a private homeowner to take reliable material, which does not require replacement for at least a dozen or two years. After all, do major repairs It will be difficult and expensive on your own. That is why it is worth choosing products from a well-known brand that protects its reputation and does not produce outright defects. But all famous companies that produce insulation materials must have some unique production technology. So you will have to be especially careful when selecting decent thermal insulation for a roof or attic, correlating new products with your own requirements. And we will help you understand the nuances.

Popular manufacturers

The well-promoted brand offers roof insulation with glass wool. In itself, it has always been considered budget, but in this case, be prepared to pay for a good name as well famous manufacturer. True, Knauf sweetened the pill and released glass wool with reduced dust emissions. Of course, it is still a good idea to exercise personal protection when working with this material. But the lack of PPE won’t be so catastrophic if you only need to put in 1-2 rolls of insulation.

Knauf recommends using the Insulation Pitched Roof series for roofs. It is offered in two versions: mats with a thickness of 150 mm are called ThermoRoll, and plates, respectively, are called ThermoPlate. Both varieties are characterized by good sound absorption and non-flammability. All other characteristics are determined only by the density of the insulation. By the way, the conductivity of Knauf products in a dry state can be immediately recognized from the marking: it is 0.034 or 0.037 W/m∙°C, and in a wet state it does not exceed 0.043 W/m∙°C.

The vapor permeability of glass wool is noticeably higher than that of basalt insulation - 0.5 mg/m∙h∙Pa versus 0.3. The manufacturer indicates hygroscopicity is also insignificant - only 0.8%. But keep in mind that this only applies to short-term contact with water.

The declared sound absorption of Knauf Insulation depends on the thickness of the insulation:

• 85% for a layer of 50 mm;
• 100% – for 100 mm.

But reviews from real customers indicate the opposite - Knauf glass wool, being an excellent insulation for roofs, does not cope with sound insulation tasks at all. Also experienced builders It is not recommended to use it where exposure to weight loads is possible.

Ursa decided to use staple fiber as the basis for its insulation instead of traditional glass or basalt fiber. And they did the right thing. Firstly, it is less susceptible to moisture than glass wool, and secondly, it does not produce allergenic abrasive dust, which makes the skin itchy and the throat sore. Although this is also glass, but modified. It has a long thread length, due to which it shows good acoustic properties, high elasticity and resilience.

• Pure One.

The Ursa Pure One series uses more harmless adhesive resins - acrylic instead of toxic phenolic. They are also distinguished by very good vapor permeability, which is especially important if you have a wooden house or you are deciding which is the best insulation for an attic roof.

Staple products are distinguished from basalt materials by stronger adhesion of fibers to each other, again due to their greater length (minimum 150 mm versus 20-50 for gabbro-basalt). So the elastic and strength properties of Urs are higher than those of traditional stone wool.

Such characteristics of Pure One allow the use of lower density insulation (up to 20-22 kg/m3) while maintaining other parameters at the proper level. In addition, lighter wool does not overload the roof wooden house.

• Ursa Geo.

Roof insulation can be done with Ursa Geo mats (aka Glasswool) from the Pitched Roof series. Dimensions of 1.2 x 3.9 m with a thickness of 150 mm and 200 mm allow you to cover a considerable area with one sheet of glass wool, speeding up work. However, the width of the rolls of 1.2 m is not always convenient to use, since the distance between rafters is usually maintained at about 60 cm. That is, a 4-meter sheet will still have to be cut evenly lengthwise. In general, judging by the reviews, Geo Pitched Roof rolls are more like blanks for cutting insulation to the required sizes. But for non-standard designs it's even convenient.

Ursa Geo is made using a special technology that provides the fibers with high elasticity and, accordingly, a good fit. In packages, the pitched roof is initially compressed, so before starting work, the rolls need to be given time to straighten or shake them several times. The manufacturer itself positions the entire Glasswool line not just as insulation, but also as sound insulation.

Bright representative basalt wool in the market of insulating materials. Here, not only the well-proven technology of random weaving of fibers is used, but also a special method for producing them. Izover slabs and mineral mats consist of corrugated gabbro-basalt threads, which themselves have good elasticity. And for thermal insulation of this kind, the ability to maintain the original volume over many years of use is a huge plus.

For attics and unheated attic spaces in a wooden house, Izover recommends roof insulation from the Optimal series. They provide the best fit to building structures, leaving no gaps. Their thermal conductivity indicators for basalt wool are excellent (0.034-0.037 W/m∙°C). Other products have the same properties:

• Special - moisture-resistant Isover Pitched roofing is used in unloaded structures operating in conditions of varying humidity.
• Universal – rigid slabs KL37, KL34 and mats KT37.

The characteristics given by the manufacturer for their special series are very interesting: insulation for pitched roof shows only 9% water absorption a day after immersion in liquid, which is considered an undeniable advantage of mineral wool. But in fact, even these few percent are enough to deprive it of its insulating properties.

No matter how good the Izover pitched roof is, its heat-saving characteristics are not too different from cheaper analogues. So the high price is just a payment for long term services without loss of volume, and for the brand.

4. TechnoNikol.

It produces basalt slabs in a fairly wide range, including for flat roofs under built-up waterproofing. In line mineral wool materials TechnoNIKOL roof insulation products have the best performance characteristics, as well as high density.

The Tekhnoruf series is represented by several versions of stone wool in different designs. The classification and labeling of individual products is based on their resistance to compressive loads in kPa. High-rigidity basalt insulation materials are available in four modifications (from 45 to 70 kPa) and are used on large construction sites with a flat roof.

For two-layer insulation, TechnoNikol produces mineral wool separately to form an insulating base and a more rigid top (marked H and B):

• N – slabs medium density(100-135 kg/m3) and quite acceptable strength at the level of 0.03-0.04 MPa.
• B – very hard basalt insulation for roofing (about 180-190 kg/m3). The trio of varying strengths from this line are capable of withstanding loads from 0.05 to 0.07 MPa.

To simplify the work, the manufacturer also suggests using ready-made solution– double insulation, which consists of glued slabs of different densities: top – 180 kg/m3 and base – 110 kg/m3. In this case, the average compressive strength is 0.04 MPa. But when installing a continuous coating, according to experts, it is better to resort to a more labor-intensive, but reliable installation in two layers with overlapping seams.

An interesting series of insulation products is TechnoNIKOL Galtel, where standard-width slabs and narrow strips of 100 mm are wedge-shaped. This allows you to create flat roofs required slope for rainwater drainage. But for pitched roofs, this brand has nothing but flimsy Rocklight.

TechnoNikol also offers a very extensive line of XPS Carbon Eco foam polystyrene insulation. Particularly successful are profiled Drain slabs with drainage longitudinal grooves, which will simultaneously perform the functions ventilation gaps. If a slight slope is required, you can use Slope EPS panels, assembled into a single wedge-shaped structure.

How to choose the right insulation?

The main criteria for choosing roofing insulation:

• Maximum service life without loss of performance.
• Acoustic properties are especially important for roofs covered with metal sheets.
• Weight and effective thickness of insulation for a specific region.
• Possibility of dense installation on a complex roof configuration.

You should also consider whether the topmost room will be a residential attic or will remain simply an unheated attic.

When choosing the best way to insulate the roof of a house, first of all you need to focus on its design, or more precisely, on the angle of inclination of the slopes. The bundle includes the type roofing material and features of its installation:

1. For cladding that rests entirely on the counter-lattice (tiles of all types, metal profiles), elastic mats and slabs made of basalt or fiberglass are suitable. They may have a low density because they do not experience loads.

2. If it is necessary to insulate mansard roof or just steep slopes, you should buy insulation that will not slide or shrink under its own weight. Glass wool is contraindicated in these cases, and mineral slabs are needed of medium density - they are quite rigid and retain their shape well.

3. It is better to install a soft roof on top of EPS slabs. The same applies to exploited roofs, where the thermal insulation is under serious pressure.

Rigid foam polymer is suitable for laying on flat and flat (up to 12°) roofs under screed. But here it should be taken into account that interior spaces all the moist air will rise to the polystyrene, but will no longer be able to pass through it - this insulation is so impenetrable. So the effect of a thermos can be avoided only with proper ventilation. Also, a layer of non-combustible material is required on top of the fire hazardous EPS. Ideally, cement filling.

Unused flat roofs are less demanding on the strength characteristics of insulation. In this case, basalt slabs are suitable, but with sufficiently high rigidity and with all the necessary waterproofing measures. In terms of price, they will be much more expensive than other types of mineral wool, and because of this their conductivity will be slightly higher. However, this drawback is not critical given the considerable thickness of the insulation.

People's opinions

“Personally, I liked Knauf for roofing. Usually glass wool makes me cough a lot, so I can’t even bother unpacking it without a respirator. And here I somehow felt more comfortable. There are no complaints about the quality and degree of insulation, but you only need to apply it in two layers, otherwise you won’t get normal sound insulation. At this price, this is, in general, a rather large expense.”

Andrey, Moscow.

“I was told to take Ursa, as they say, by the project itself. They saved on timber for the roof, so it turned out that they left 80 cm between the attic rafters. Buy standard slabs/mats? So they have a width of 60, and a length of 1-1.2 m - still cut them, and write off the remains for scrap. And here is such beauty: Ursa insulation in rolls for cutting! In general, I cut them across to my sizes. There was waste, but not as much as expected. The only thing is that, like any glass wool, Ursa pricks and itches.”

Egor Firsov, Rostov-on-Don.

“I respect Izover very much, but somehow I didn’t come across the pitched roof - I chose from universal mats. A year ago, at a friend’s dacha, I gutted KL and KT insulation for comparison and settled on slabs. The fibers in them look longer, which means they will stick together well. And the weaving is more uniform, which is also a plus for steep attic slopes.”

Alexander, Yekaterinburg.

“In my opinion, TechnoNikol does not yet have any worthy offers for private developers: either professional Technoruf at an exorbitant price, or polystyrene, which is own roof The sense of self-preservation does not allow throwing. It's better to stop at basalt insulation from Izover - there is plenty to choose from and what to buy at a reasonable price. Reviews about it are mostly good."

Gregory, Perm.

“I’m generally against glass wool on the roof or in the walls, but I liked Knauf Insulation (only in the Dom version). I also decided to buy Knauf Dacha for testing, but it turned out to be too soft - I used it to insulate the attic in the extension. During work, there was no feeling of prickliness, but then my hands itched up to the elbow. So I don’t recommend neglecting gloves and a mask.”

Vasily Pavlyuk, Nizhny Novgorod.

What to consider before purchasing?

For the right choice Insulation schemes require calculation of losses through the roof, but this mainly determines the overall thickness of the “pie”. The characteristics of the materials discussed above are practically the same - the difference in thermal conductivity in thousandths between mineral and glass wool will not be significant. For this reason, the amount of insulation in both cases will be approximately the same.

All you have to do is select products with dimensions that will produce the least amount of waste during installation. If these are basalt slabs, they should be a centimeter wider than the distance between the rafters in order to be clearly installed apart. Rolls of fiberglass insulation should be taken in length corresponding to the roof slope.

Don't forget about environmental friendliness - permanent residence in a house with a source of toxins or allergenic dust can provoke the emergence of chronic diseases. Study the information about the composition of the insulation, paying attention to special attention content of formaldehyde, phenolic resins. Of course, you shouldn’t hope for their complete absence, but the lower their percentage participation, the better.

When insulating the roof, avoid using too light types of mineral wool - not a single manufacturer in our country has yet been able to achieve normal quality of such products. Gaps in mats and weak adhesion of fibers negate all costs for thermal insulation.

But be careful - the structure must withstand total weight the whole “pie”, taking into account snow loads. Focus on an indicator of at least 40-45 kg/m3 for a pitched roof wooden house or attic. But for flat roofs, the main factor remains strength characteristics.

Thermal conductivity is an important characteristic of building materials. The modern consumer prefers a product with the best performance characteristics, namely a popular brand.

It is difficult to find a good manufacturer, especially when there are so many products from different companies on the domestic market that it is difficult to understand where the product is of high quality and where it is not.

The main characteristics of mineral wool that you should pay attention to when choosing:

1. Thermal conductivity.
2. Density of wool.
3. Water-repellent properties.
4. Chemical protection.
5. Thickness of building material.

Cost is the first thing buyers pay attention to when choosing insulation, but it is worth knowing that the price from different suppliers will vary greatly, since some offer installation work and their own delivery right away.

When choosing good insulation attention should be paid to the list of material properties. The more distinctive characteristics, the better. By comparing the capabilities and cost of building materials, you can choose the best option for yourself.

The following companies have become clear leaders in the production of thermal insulation:

1. Rockwool. The mineral wool produced by the company is actively used in many areas. The brand's mineral wool is made exclusively from basalt.
2. Izover. Leader among manufacturers of thermal insulation.
3. The company produces thermal insulation using a special environmentally friendly technology.
4. Engaged in the production and sale of various building materials, including those related to thermal insulation.
5. TechnoNIKOL. Manufacturer of high-quality insulation.

Among the leading companies, it is worth noting two, which will be discussed further. Which is better: Ursa or Knauf, whose products cope better with the thermal insulation of premises. Thermal conductivity is one of the most important characteristics for any insulation, therefore, the lower it is, the smaller the layer applied to walls, floors, roofs and other structures will be.

Products trademark Knauf is distinguished by fairly high performance characteristics and environmental friendliness. Their product is completely harmless to others. Unlike similar insulation materials, the Knauf brand does not use phenol-formaldehyde resins, since they contain many different harmful substances.

The most significant performance properties:

1. It insulates the room well from extraneous noise.
2. Mold and other formations do not form on the material.
3. Fireproof. If a fire occurs, the mineral wool will resist further spread of fire.

URSA produces thermal insulation materials that effectively insulate walls, floors and roofs, as well as ventilation ducts and other communication networks. Such thermal insulation absorbs noise well and has a long service life. IN different areas(industrial and private) the excellent characteristics of mineral wool from the manufacturer URSA determined the popularity of the product.

Ursa fiberglass is distinguished by elastic and durable fibers. Between them, layers appear, ignited by air, which retain heat more efficiently. In addition to its distinctive insulation properties, mineral wool can completely isolate a room from extraneous sounds. Rating 9.9 points out of 10.
