The best stone wool insulation - a review of manufacturers and brands

Which insulation is better?

The following insulation materials were selected for the experiment:

• Stone wool: Rockwool, Baswool, TechnoNIKOL
• Glass wool: Isover, Knauf

The experiment compared the thermal conductivity of insulation; for these purposes, wooden boxes 50 x 50 cm were constructed, which were insulated with 150 mm thick cotton wool. A 95 W incandescent lamp was placed inside the boxes and remained in the boxes for 60 minutes. Testing of insulation was carried out outdoors at sub-zero temperatures of about -5 - 6 degrees. After each test material was kept in the cold for 60 minutes, shooting was carried out with a thermal imager.

Shooting with a thermal imager is divided into 3 stages:

• Filming the outside of the box (the temperature of the insulation was taken from the outside)
• Filming the inside of the box (we looked at which insulation accumulates heat more)
• Filming the joints of insulation (we looked at which insulation materials better prevent the formation of cold bridges)

Results of shooting with a thermal imager of the outer part of insulation

The test results showed that the outer side of the insulation still warms up. This means that heat loss, although insignificant, is still present. It is difficult to identify a noticeable leader or outsider, since the indicators differ slightly. Baswool (1.1C) showed the lowest heat loss among stone wool insulation materials; Knauf (-0.8C) was the best among glass wool.

The insulation showed a significant difference when comparing the internal temperature of the boxes.

Comparison of internal box temperatures

The best performance among stone wool was shown by Baswool and TechnoNIKOL (78.9C each). The best glass wool was Knauf (61.9C). As for comparing joints, glass wool insulation showed the best results. This is not surprising, since glass wool fibers are longer and more elastic, glass wool has excellent compression properties. Basalt or stone wool (these are the same thing), denser insulation and less elastic, they are more difficult to install in frame walls. In general, summing up the following winners: the leader among stone wool insulation was BASWOOL, and the leader among glass wool was KNAUF.

Insulation for frame houses Hotrock (Hotrock)

Insulation for a frame house

With the advent of frame technologies, the dream of owning your own home has come closer to reality for the average person. The home promises to be durable and strong; it will certainly be comfortable in the summer. However, if you intend to live in such a house all year round, you will have to purchase insulation for the walls of a frame house and take care of insulation.

Which insulation is better?

In the good old days, people insulated buildings exclusively with natural materials - tyrsa, sawdust, straw, adobe, peat, adobe stones. The work is dirty and labor-intensive. There is no point in repeating past experiences today, because modern materials have appeared:

• sheet foam (expanded polystyrene);
• mineral wool;
• extruded polystyrene foam;
• sprayed polyurethane foam;
• expanded clay;
• ecowool.

So, let's choose the best insulation for a frame house :

What remains is mineral wool - glass, stone, slag. This insulation for a frame house has decent characteristics:

• high heat and sound insulation;
• fire safety;
• resistance to rotting (durability);
• vapor permeability;
• resistance to chemical and mechanical stress;
• environmental friendliness.

Tips for choosing mineral wool

Despite all the advantages, this material has a minus: hygroscopicity. If moisture begins to penetrate behind the frame skin, the material will gradually lose its thermal insulation properties. The wet cotton wool is compressed and opens the way for cold air from the street. The attempts of some developers not to remove the cellophane packaging from the material did not justify themselves, since it is enough not to notice a few holes, and, consider, there is no protective film. You will have to carefully study the modifications so that later you are not tormented by thoughts about what kind of insulation for a frame house you bought - good or not so good:

Comparison of modern insulation materials

URSA, ISOVER, TERMOLIFE, PAROC, ROCKWOOL are excellent foreign brands. But you are building a budget frame-panel structure, and when you buy insulation for a frame house, the price becomes one of the determining factors. Russian-made Technonikol basalt products (slabs) are suitable in all respects - including the percentage of resin content. The material is non-aggressive, vapor permeable, and moisture resistant.

We also recommend domestic ISOROC - the density is higher than that of the popular and world-famous ROCKWOOL, and the cost is lower. BASWOOL (BASVUL) is also a material with an affordable price, but does not really meet the requirements for insulating the foundation (ground floor). For this purpose, take a special type of insulation - for example, from the URSA (URSA), KNAUF (KNAUF) product line.

Technological rules for insulating a frame house with mineral wool

What should be the thickness of the insulation in a frame house , which slabs should be preferred - 50 or 100 mm? Experienced builders prefer 50 mm slabs, and assemble them into a two-, three- or four-layer array with offset seams with a total thickness of up to 150-200 mm. Yes, this is a kind of reinsurance, but in the end they always end up with a cozy, warm home. To insulate the floor, the thickness of the insulation should be 250-350 mm, the upper floor and warm attic - 200 mm.

The choice of insulation materials is so extensive that it is easy to get confused. Pay attention to the characteristics of a particular material and study the instructions. Insulation is the most important element of a frame wall; the quality of insulation of a frame house depends on its choice.

Which basalt wool is better?

Today, thermal insulation is widely used in construction. It helps reduce heat transfer in places where it is necessary to maintain a certain temperature (residential buildings, food warehouses). Among the different types of thermal insulation, basalt wool is often used, as it is a reliable and optimal way to retain heat in cold winters and coolness in hot summers. Now we’ll talk about basalt thermal insulation and the features of choosing the material.

Contents of the article about which basalt wool is better

• Criteria for choosing basalt wool
• Material Density
• How to decide on the manufacturer of basalt wool?
• Where to buy basalt wool?

How does this insulation work? Basalt wool consists of fibers that do not allow cold and hot air to pass through. This creates a temperature difference between the separated spaces: the street and the room. Thermal insulation allows you to save a lot of money on air conditioning and heating of the room.

Criteria for choosing basalt wool

Many buyers are wondering: which basalt wool is better? The construction market offers a variety of materials from different manufacturers, which differ in many respects: destination (insulation of floors, walls, roofs, etc.), weight, electrical conductivity, ability to withstand loads, level of sound insulation, etc. That is why you should approach the choice of basalt wool extremely carefully and carefully.

1. Fire resistance of a material is the effectiveness of inhibiting the spread of fire over time. The following conditions are considered here:

• smoke formation;
• incombustibility, flammability and fire safety. Consumers want to live in a safe home, so they are willing to overpay considerable sums for this quality.

2. Thermophysical characteristics: vapor permeability, thermal conductivity, resistance to aggressive and chemical environments, non-flammability and non-flammability.

3. Strength characteristics, wear resistance, resistance to mechanical stress, durability and heat resistance.

We have already described these and other characteristics of the material in the article Characteristics of basalt wool. Based on them, insulation is selected for specific purposes.

Material Density

The most important characteristic for insulation is density. The most popular types of insulation have a density of 35, 50 and 90 mm. This parameter affects the destination, the load on the insulation, and installation methods. The first two options are suitable for a private house or cottage; they are used for thermal insulation of walls, floors, roofs and ceilings. Here the material is not subjected to heavy loads.

The best insulation for wooden and frame structures Isoroc Izolight 1000x500x50mm 8 pcs.

• lasting;
• environmentally friendly;
• non-flammable;
• optimal in price and quality.

The top insulation for the home opens with stone wool, which is sold in packs of 8 slabs measuring 100x50x5 cm. One sheet has an area of ​​0.5 m2, a pack - 2 m2. Material density 50 kg/m3, thermal conductivity 0.034–0.04 W/mK. The material muffles external sounds. It is not flammable, does not absorb water, and does not mold. The cost of packaging is 400–550 rubles. When ordering from the factory, the price is 1600 rubles. for 1 m3, that is, 320 rubles. for packaging excluding transport costs.

Used as thermal insulation for frame-type wooden houses. Basalt material is breathable, it allows air to penetrate freely. This ensures ventilation of the rafters in the attics, which protects the wood from rotting. It is not suitable for insulating external walls, but can be used in lightweight brickwork with laying inside the wall.

How to choose materials for thermal insulation at home

Note that there is no universal best insulation. For each individual case, you need to select the appropriate material.

To figure out how to choose thermal insulation for your home, consider its types:

• Mineral wool
  . Easy to install and insulates well. But it cannot withstand pressure and is not suitable for wet areas. Depending on the type of raw material from which it is produced, there are stone (basalt), glass and slag. Basalt-based home insulation is completely non-flammable and does not chip. Glass wool has two main advantages: it is non-flammable and very cheap. But working with it is not at all comfortable, since the material is itchy and causes allergies. Slag wool is only suitable for attics and non-residential buildings as it is not environmentally friendly.

• Foam glass
  . Available in blocks, durable. This is a new and expensive material.
• Styrofoam
  . Its popularity is determined by its low price. Does not absorb moisture, is partially vapor permeable, does not rot, does not mold. Durable. But it has low strength. Rodents love to build nests in polystyrene foam. The optimal density is 25 kg/m2.
• Expanded polystyrene
  . This insulation is made from the same material as foam, but it is modern and more durable. Used for walls, foundations, flat roofs. At the same time it provides moisture insulation. Currently, polystyrene foam is the leader in the thermal insulation rating.
• Sheet polyurethane foam
  . Its properties are similar to expanded polystyrene, but it is breathable and easily absorbs water.
• Foam
  . It is made on the basis of polyurethane foam or penoizol. Good for insulating walls outside. Covers the surface completely, without cold bridges, due to which the walls after treatment have minimal thermal conductivity. But insulation in this way is expensive - the technology requires the use of special equipment and qualified personnel.
• Foamed polyethylene foam
  . There is PPE or NPE. Take only PPE - it is more durable. It is used for insulating pipes, internal walls, and floors. There are options with reflective foil film.

• Thermal conductivity
  . Shows how much heat in watts the material will lose. The lower the coefficient, the better. The average value is 0.038–0.046 W/mK.
• Vapor permeability
  . The ability of the material to breathe, allowing moisture vapor to pass through. Quality required for timber structures.
• Shrinkage
  . It is desirable that it be minimal or absent. Otherwise, over time, under the influence of its own mass, the thermal insulation will decrease in volume and deteriorate its properties.
• Hygroscopicity
  . Determines the ability of a material to absorb water vapor. Materials with high hygroscopicity are less effective because liquid increases thermal conductivity. Also, such insulation cannot be used in damp places.

• Operating temperature
  . Correctly selected insulation for this parameter will serve with high quality and for a long time. For example, in the northern regions frosts can reach -40 and -50 °C. In summer, metal roofs heat up to 80–90 °C.
• Flammability
  . Insulation materials are flammable and non-flammable. Indoors it is better to use non-flammable or low-flammable ones. Also, non-combustible insulation materials should be used in fire hazardous areas.
• Environmental friendliness
  . Important for use in residential areas. Environmentally friendly materials do not emit harmful substances.
• Firms
  . There are a lot of manufacturers of high-quality thermal insulation. Among the brands that have proven their effectiveness are the following: Rockwool, Isoroc, Energoflex, Penoplex, Akterm Nord, TechnoNIKOL, URSA, Hotrock, KNAUF, Isover, Ecostroy.

Material calculation

Differences in the dimensions of mineral wool elements can mislead you. Professionals try to save working time. The price of a mistake is the same for everyone - budget overruns and loss of time.

To perform calculations, use an online calculator. It will take into account all the necessary quantities, parameters and conditions.

A small reminder on using the calculator:

• Please note that not all Russian settlements are represented in the list of cities. Therefore, try to choose options that are minimally distant from the location of your home. This is important because this parameter determines the average winter temperatures;
• all numerical values ​​(thickness) are displayed in millimeters. Just in case: 1 m is 100 cm or 1000 mm;
• We recommend looking at the detailed characteristics of insulation on the manufacturers’ websites. There you will also find recommended prices for this type of product;
• All calculations are approximate, so it would not be superfluous to add 10% to the results obtained.

Having obtained the thickness of the thermal insulation as a result of calculations and knowing the area of ​​the walls, it is easy to calculate the volume of insulation. We hope this is helpful.

Comparison of Rockwool insulation with TechnoNIKOL insulation

With the right choice of insulation, you can significantly reduce the amount of heat lost in the building, as well as significantly extend its service life. Everyone wants their home to be as comfortable as possible during a howling blizzard and bitter frost. After all, if there is no wind anywhere in the building, then watching the snow fly will only bring aesthetic pleasure. To ensure a high level of comfort in your room, you should resort to using insulation.

The mineral board of the Rockwool company has a high level of demand in its market segment, because compared to others it is distinguished by the highest level of quality and long-term preservation of performance characteristics.

The Rockwool company comes from Denmark and is rightfully considered a leader in the field of stone and mineral wool. The entire range has the following features:

• the material is produced exclusively using the most advanced technologies, which the company is constantly improving;
• the entire line of the manufacturer is completely safe and does not harm either people or the environment;
• matter significantly reduces the cost of heating the room.

The company was born back in 1909, but the world-famous brand today appeared only thirty years later. At the moment, the concern has expanded, having more than 25 enterprises in all corners of the world. Constant development and improvement allowed the concern to create a high-quality product. It is important to note that Rockwool specializes only in the production of stone and mineral wool, which makes it a narrow-profile enterprise.

The Technonikol company is one of the five largest and most influential European manufacturers in this segment, but produces not only thermal insulation, but also tiles, roofing felt, membranes, primers, mastics and other building materials.

Compared to Rockwool, Technonikol uses not only basalt, but also extruded polystyrene foam to create its products. This material is beginning to be used more often to provide insulation both in our country and abroad. Compared to other insulation materials, this material has less weight, which reduces transportation costs and facilitates installation. But at the same time, it is rigid and durable, which makes it suitable in places where less durable thermal insulation would be inappropriate. The only problem is that the presented material is susceptible to fire, releasing toxic substances during this process. But there is also a wide range of basalt wool.

Rockwool products are undoubtedly of higher quality, since the company specializes in a specific segment and directs all its efforts into it, but TechnoNIKOL is also not far behind in technical parameters, and also has a more affordable price. So it’s up to you to decide which choice is right.

Comparative test - review of basalt insulation

On this page we publish a comparative test - a review of basalt insulation, produced in the form of sheet material.
Insulation of walls with basalt-based mineral wool has recently become widespread. This is facilitated by three main positive properties of basalt wool - good vapor transmission, good thermal resistance and non-flammability.

It is worth immediately noting that in terms of these characteristics, almost all brands of basalt insulation present on the market are very close to each other. If you take cotton wool from different manufacturers of the same density, then the ability to transmit steam, and the thermal resistance and ability to withstand fire will be at approximately the same level.

The same cannot be said about other consumer characteristics, such as ease of installation, cost, accessibility to consumers, packaging quality and durability.

It is these characteristics that we decided to focus on in our review, what we got - read below. To conduct the review, we took four of the most famous brands of wool manufacturers, and from each we chose insulation with approximately the same density. All sheets are considered 50 millimeters thick.

Glass wool Knauf

The production of insulation of the German brand KNAUF complies with GOST for the production of glass wool. The raw materials are silicate rocks and glass cullet; phenol-formaldehyde resin is used as a binding element.

Thermal insulation materials made on the basis of fiberglass are widely used. They can be used to insulate both vertical and horizontal surfaces, subject to minimal load on the material.

Knauf glass wool has several advantages:

Roof insulation: how to insulate?

Manufacturers

When choosing the best insulation for a roof, you should focus on materials with high thermal insulation properties and low weight. After all, the rafter structure does not “welcome” unnecessary “overloads”.

The material itself must be “long-lived” in an environment of seasonal temperature changes, withstanding temperature expansion, having low moisture absorption and at the same time having low flammability. And one more thing... The insulation should play the role of a sound insulator.

The familiar thermal insulating material polystyrene foam as roof insulation is far from an ideal option. He is “afraid” of high temperatures (the sun shines well on the roof in summer), and there’s no point in talking about sound insulation at all (this, of course, is all relative)!

The optimal insulation for roofs is mineral wool, which is divided into two large groups:

• made from basalt-containing rocks;
• made from fiberglass.

In addition to different melting temperatures, the technology for producing mineral wool from glass (400 ° C) and basalt rocks (1100 ° C) is the same. Prepared in the required proportions, the mixture of raw materials is melted to a fluid state. After which it is fed to centrifugal rolls rotating at high speed, as a result of which it is “sprayed” into thin fibers, which are picked up by the air flow and at the next stage are mixed with the binder component. Next, a “carpet” of the resulting fibers is formed, which is molded on special machines and polymerized in heat treatment chambers.

These processes determine the physical and mechanical properties of mineral wool.

Then trimming, packaging, transportation... and installation on site.

Mineral wool is formed in the form of slabs or in the form of rolls.

Among the manufacturers of thermal insulating mineral materials, the following companies should be noted: Rockwool, Isover, Knauf Insulation and TechnoNIKOL. Their big names have become popular household names for materials.

Isover

Izover is a representative of thermal insulation materials that has gained enormous popularity. Its main “vocation” is to improve the thermal insulation properties of buildings, in particular their roofs. Using an isover is a direct path to saving on heating.

Isover is a relatively cheap roof insulation.

What other advantages of this material can be named?

Let's start with the main thing for many happy “foremen” of the construction of their home - isover has an affordable price with high quality, environmental friendliness, significant thermal insulation properties, “longevity” and is easy to install.

Isover will keep the heat under the roof of your home!

Rockwool

Rockwool is an indispensable assistant in energy saving during heating. The building must be warm and at the same time “economical” - these are mandatory parameters of a modern construction project. The organization of insulation of a building depends to a large extent on the insulation of its roof.

An excellent insulation material for a rockwool roof is stone wool made from inorganic mineral raw materials.

Advantages: non-flammable and natural raw materials. The parameters correspond to the highest fire safety class A1.

Rockwool mineral vara can withstand temperatures of more than 1000 ° C, which, together with insulation, makes it possible to create a fire-resistant barrier in the walls and roof of the building.

And that is not all! Due to its “fibrous” nature, Rockwool wool has excellent sound-proofing (sound-absorbing) properties.

Excellent thermal insulator Rockwool

Knauf Insulation

KNAUF is the largest manufacturer of building materials used in interior and exterior decoration. Their thermal insulation materials deserve special attention.

This is mineral wool based on basalt fiber, which has all the positive qualities already listed above. Knauf materials have high vapor permeability, low moisture absorption, and resistance to biological and chemical influences.

TechnoNIKOL

TechnoNIKOL is another popular thermal insulation “brand” that offers high-quality thermal insulation materials in the “open spaces” of the construction market. The company’s production “capacities” (37 enterprises) are distributed in the territories of Russia, Ukraine, the Czech Republic, Lithuania, and Belarus.

Teplonikol Corporation owns its own sales network and representative offices in 35 countries. These are modern technologies in the production of sheet and roll insulation for roofs and walls.

Some features of choosing roof insulation

For buildings for individual use, if it is being built for a long time and “for oneself,” use stone (basalt) mineral wool from Rockwool.

The construction of commercial buildings is mainly accompanied by roof insulation with glass wool, because it is at least two times cheaper.

Note! In residential or attic spaces that are simply visited by people, it is recommended to install a wind barrier protective film. It will protect the human respiratory system from fiberglass flying in air currents from drafts.

The thickness of the thermal insulation coating must be correctly calculated. Because the small thickness of the insulation, as well as non-compliance with the rules for installing mineral wool and vapor barriers on the roof, lead to getting wet due to condensation and freezing of the roof structures.

Frost on a “thermally insulated” ceiling

Due to improper installation of thermal insulation material, cold bridges are formed in the thickness of the “roofing cake”, which after some time lead to the appearance of dampness and mold. And there is no point in blaming the roofing - it has nothing to do with it! The reason is below, underneath...

Condensation on the surface of the vapor barrier

Insulation with mineral wool necessarily “requires” the use of a vapor barrier hermetic coating - a special polyethylene film reinforced with mesh. The joints between the film sheets must be glued with special adhesive tapes.

Important! If you do not make a high-quality vapor barrier barter, then warm air from the room in winter will penetrate into the thermal insulation layer. And when it comes into contact with cold surfaces, water vapor contained in the warm air will condense on them, which will lead to soaking and the appearance of dampness.

Properly organized work and the selected insulation for the roof plus vapor barrier of the roof of the house is the key to your long-term “dry” existence in it.

Isover - high quality mineral wool to choose from

The manufacturer offers two solutions: glass wool and stone wool. This is a big plus when choosing thermal insulation, since both of these materials are usually in demand in the construction of a particular facility. Izover has an excellent reputation in Russia and offers thermal insulation only with environmental quality certificates. The constant introduction of modern technologies makes it possible to improve the characteristics of manufactured products and reduce costs. The latest “new product” from Isover is the release of mineral wool with high strength and elasticity, without dust and with a minimum of “prickliness”. In terms of quality, products under this brand are unlikely to compare with more expensive competitors, but in terms of price/quality ratio, Isover mineral wool is one of the best.

Rating : 9.9 points out of 10

Reviews from builders : “Isover mineral wool is cheaper and better than many other insulation materials, so I use it for large volumes.”

Beltep is a good and inexpensive mineral insulation

Basalt mineral wool from this manufacturer is available in two packages: rolls or slabs and is considered a good solution for creating multi-layer thermal insulation systems. The high rating of Beltep basalt wool is confirmed by reviews from construction forums and from individuals.

Among the advantages of Beltep mineral wool insulation:

• fire safety;
• environmental friendliness;
• vapor permeability;
• resistance to deformation;
• acoustic comfort;
• large selection of materials by density;
• low hygroscopicity;
• affordable price.

In addition, the material has high rigidity, is shape-resistant, and is easy to cut and install. When compared with European manufacturers, BelTep is inferior to them in some respects, but when there is a choice between it and many Russian brands, they often buy mineral wool from a Belarusian company. So we can say that BelTep basalt wool is the best competitor to many similar proposals.

Rating : 9.5 points out of 10

Reviews from builders : “I tried Beltep mineral wool in my work. The density is good, it doesn’t sag, it stands clearly between the rafters without falling out.”
