Stone wool is one of the most popular insulation materials from the mineral wool category. Gabbro-basalt rocks are used for manufacturing, and the resulting product has found active use in the field of construction. Used to obtain high-quality heat and sound insulation layer. On modern construction market The most common is TechnoNIKOL basalt wool.

Compound

When producing insulation, specialists use rocks, or rather gabbro-basalt raw materials. Thus, the resulting heat insulator is not affected by fire. The fibers can only melt smoothly when they are affected by a temperature of 1000 degrees. Thanks to this property mineral wool TechnoNIKOL began to be used to protect houses from destruction and deformation in a fire.

Detailed description

Before purchasing TechnoNIKOL stone wool, you need to familiarize yourself with its technical characteristics in more detail.

Coefficient of thermal conductivity

This stone criterion may vary depending on the type of material. Be within the range of 0.034 to 0.047 W/m*S. Thus, it becomes clear that 10 cm of insulation can preserve thermal energy as good as 38 cm of timber or 140 cm of brick.

The insulation process using TechnoNIKOL wool is carried out in 1-2 layers.

Density of slabs

This characteristic of the material is determined by the thermal conductivity coefficient. If we consider the material Rocklight and Technolight, then its density is 30-40 kg/m3, but the material Technoflor, which is used to insulate the floor under the screed, this figure is 81-185 kg/m3.

Degree of vapor permeability

This characteristic is also one of the main ones. The lighter the material, the better its vapor permeability. Consequently, the microclimate in the house will be comfortable for living.

In addition, insulation with high vapor permeability rates has a longer service life. This is due to the fact that water molecules do not retain steam on their surface for long. Since TechnoNIKOL wool consists of 99% air, it allows steam to pass through perfectly. The degree of permeability of the material will be 0.3−0.6 mg/(m.h.Pa).

Degree of water absorption and fire-resistant properties

Since specialists used various additives in the production of TechnoNIKOL stone wool, the resulting material can perfectly retain moisture. The water absorption level of the heat insulator will be 1-2%.

Because mineral slabs TechnoNIKOL – non-flammable material, then it is advisable to use them for thermal insulation in those houses where there is a high risk of fire. TechnoNIKOL slabs are not combustible, and the melting process occurs only at a temperature of 1000 degrees.

If a fire occurs, TechnoNIKOL stone wool will be able to delay the spread of the flame for some time. Moreover, it protects against fire and other materials that are less resistant to fire. But what is the thermal conductivity of mineral wool and how is it determined. information from this will help you understand

Life time

The service life of TechnoNIKOL mineral wool is quite long even under unfavorable conditions. The minimum service life is 50 years. This result is achieved due to the fact that the material has excellent characteristics. Basalt fibers do not rot or corrode. In addition, rodents are not scary for them. But the service life of the material can only be increased if it is installed correctly. So during installation you must take care of hydro and vapor barrier.

But the video from this article will help you understand how basalt wool differs from mineral wool and what is better to choose for your construction project:

Varieties

Today TechnoNIKOL mineral wool is presented in a wide range, which allows developers to choose the most successful option under certain operating conditions.

It will also be interesting to know what it is. For those who want to know more about the exact materials, it is worth reading the contents of the article.

Stone wool, one of the varieties of mineral wool, is perfect for insulating a house and any room in it. With the help of our advice, you can choose the right material, make high-quality installation and take care of its long service life.

Stone wool: what is it made from?

Cotton wool is made from rocks of basalt, marl or metamorphic origin. Basalt rocks are considered the best component. However, the quality will be determined by the acidity, which must be controlled by carbonate additives. The higher the acidity, the stronger and more durable the cotton wool.

Stone wool insulation: what is it made of? Stone wool also contains a binder that holds the fibers together. The most well-known substances are synthetic. They contain phenol-formaldehyde resins and various impurities that make the material waterproof.

On modern production Stone insulation is made from a special component - “Pele's hair”, or glass fiber. The technology of stone wool for its production consists of a number of stages, the main of which is the separation of the rock into fibers.

Characteristics and indicators of stone wool

The material has several important properties, indispensable for repairs or construction.

Thermal insulation. Insulation of walls with stone wool - great way to protect yourself from the cold in winter and from the heat in summer. The temperature in the room will be constantly regulated. The effectiveness of this property depends on the components in the composition. It turned out that stone wool for wall insulation is the right solution.
Does not ignite. Even at temperatures above 1000˚C, stone wool does not ignite. Therefore it refers to safe materials, and, moreover, protects other flammable parts of the house, preventing the spread of fire. Although binders evaporate already at 200˚C.
Permanent form. Thanks to this characteristic, cotton wool can withstand mechanical stress. This allows you to use stone wool for floors that are constantly under load. Efficiency depends on the binder chosen.
Soundproofing. Will give simple protection from street or neighbor noise, since fibers interfere with the propagation of sounds.
Waterproof. Excess moisture indoors it comes out without getting into the cotton wool. This property helps maintain optimal humidity. And no matter how humid the air is, stone wool always remains dry, and mold and other nasty things do not grow on it.
Environmental friendliness. During production and operation environment not subject to negative influence.

Advantages and disadvantages

Mineral wool for insulation has the following advantages:

Non-flammable;
Waterproof;
Stone wool - insulation for walls - has a wide operating temperature range;
Eco-friendly;
Safe during installation and operation;
Good heat and sound insulation;
It is easier to insulate anything with stone wool than with other materials.

Flaws:

Insulating walls with cotton wool is a costly undertaking. Don't expect to buy cheap cotton wool. Low prices they say that it contains many impurities and low-quality materials.
Dust. The process of insulating the walls of a house with stone wool is accompanied by a copious amount of dust, especially if it is not handled carefully. For protection, it is advisable to take a respirator, although a regular mask from a pharmacy will do.

Stone wool: application

Cotton wool insulation is used in the construction of baths, saunas, swimming pools, and when laying communications, wells and air ducts. It is even placed in the foundations of houses.

Depending on where the insulation will be used and what load it will bear, it is divided into classes:

Soft. Suitable for laying wells and ventilated walls.
Semi-rigid. Suitable for walls in multi-storey buildings, for thermal insulation of pipes.
Hard. Used in foundations, floors.

Is there any harm to health during installation?

Many inexperienced builders often confuse stone wool and glass wool, although in fact they are two different materials, belonging to a single class of mineral wool. Because of this, a common myth has arisen that stone wool, like glass wool, is also harmful to health, damaging the eyes and lungs. But this is just a delusion.

The point here is its special structure. Insulation - stone fiber bound with formaldehyde resins, they do not collapse and do not spread harmful substances. Therefore, we confidently declare that this construction material absolutely safe.

How to choose stone wool?

Before purchasing stone wool, you need to find out the amount of material needed and calculate the load that will be placed on the insulation.

We have already said that the prices are high, but you can still save money. The cost will be influenced by the following factors:

Density of wool;
Manufacturer;
Binder and rock category;
The presence of another layer of coating;
Quantity purchased.

When purchasing, be sure to look at the instructions; they usually indicate the scope of use of stone wool and its technical characteristics. The most trusted companies are Ursa (URSA), TechnoNIKOL and Rockwool. The last company is located in Denmark; insulating materials from this country - the highest quality, since strict certification bodies work there.

When choosing, check with the seller how the fibers are arranged: horizontally, vertically or in a chaotic order. The first two types prevent the material from deforming, and the latter provides good heat and sound insulation.

Depending on the density, stone wool is usually divided into categories. Stone wool: wall slabs:

Brand P-75. Suitable for horizontal internal surfaces, on which there is no load, for insulating pipelines.
Insulation for walls is wool grade P-125. Suitable for both horizontal and vertical surfaces. It is ideal for insulating ceilings, floors and the inside of walls.
PZh-175. Stone insulation for walls made of metal profiled sheets or reinforced concrete.
Insulation wool PPZh-200. The hardest stone wool. This type is used in engineering buildings, protecting them from fire.

Which mineral wool is best for wall insulation?

Insulating a house with stone wool begins with choosing a manufacturer.

Rockwool "ROCKWOOL" - popular both in domestic market, and abroad. It has the following distinctive characteristics:

Good level of strength;
Mineral wool for wall insulation lasts from 15 years;
The fibers are arranged in a chaotic manner;
Helps save electricity, as the manufacturer claims;
An additional layer that increases moisture resistance.

Stone wool "TechnoNIKOL".

Produced only on the basis of basalt rocks;
Additional layer for noise reduction;
Light weight, making work easier.

Insulation for walls stone wool "URSA":

Special packaging will make it easy to transport and work with the material;
Does not contain formaldehyde resins, therefore it is recommended for schools, hospitals, etc.

Buying a truly high-quality product can sometimes be difficult. Therefore, you need to know some important points.

Pay attention to where and how the cotton wool is stored. Most often, it is stored in its original packaging and wrapped in shrink film. Make sure there are no holes or cuts on the packaging. Vata should not be on outdoors, but under a canopy.
If stone wool is packaged in cardboard boxes (they usually contain expensive insulation materials), then its storage location must be protected from moisture. Even after getting a little wet it will be unusable.
Purchase goods only from trusted sellers. Give preference to those stores that are located closer to you - this will reduce the cost of delivery.

Installation of stone wool

Before properly insulating a wall with mineral wool, you need to determine where the work will be carried out. After all, insulating the walls of a house with cotton wool will look different in each area. One technology is used on the facades, and a completely different one on the attics.

Balcony and loggia

Effective insulation of a house with stone wool directly depends on quality training surfaces. Therefore, it is logical to briefly talk about it.

Remove all excess debris from the loggia. Do necessary measurements, calculating the amount of mineral wool. Assess the load on the floor.
Next comes the glazing of the balcony. Here it is better to give preference plastic windows. Seal all cracks in frames and fencing polyurethane foam. This will greatly protect the balcony from moisture and cold.
Waterproofing is the next step. Protective means(roll or coating) must first be applied to the floor and ceiling. But wall protection is also desirable.

Only now can you proceed directly to installation. Insulation with mineral wool slabs occurs as follows:

The first step is to make the sheathing. It is most often made of wood (less often - of metal). Optimal thickness timber - 1 cm more than that of a stone wool slab. The dimensions of the cells in the grid should be about a centimeter smaller than a piece of insulation.
Insulation for walls is wool: installation goes from top to bottom: first the ceiling, then the walls and the floor. The ceiling needs denser mineral wool; regular mineral wool is suitable for walls and floors.
Special glue is applied to the plate and it is placed in place in the cell. Before doing this, do not forget to clean the surface from dirt and remove any uneven surfaces.
You can press the slab tightly and evenly using plywood. suitable size. Thermal insulation: stone wool is the best material for this.
The last stage is vapor barrier using penofol (it is sometimes replaced with ordinary polyethylene).

Stone wool for attic walls

After you have installed the rafters and laid the roof on them, you can begin insulating the house with cotton wool. But first you need to create a layer of waterproofing. It will not allow water to get on the mineral wool and on wooden structures. The best material for this purpose - ordinary polyethylene. Fastening is carried out with a stapler.

If the waterproofing layer extends over the entire surface of the roof (up to the ridge), then the insulation can only be laid up to the attic ceiling. This is done only to save money. High-quality repair implies insulation of the entire roof.

When laying stone wool, the most successful option is when the width of the roof beams is equal to the width of the slab. In this case, they are simply placed between them, attached to a stapler. Additional reliability will be provided by slatted sheathing or rope mesh laid underneath. All resulting cracks are sealed with polyurethane foam, and the sheathing (if it is made of wood) is treated with an antiseptic. Stone wool insulates wall slabs perfectly.

The last layer is the vapor barrier. As suitable material Many builders choose glassine - it is cheap and performs its functions perfectly. It is attached to the rafters with a stapler; it is advisable to cover the attachment points with tape.

Insulation of external walls with stone wool

In the process of insulating a house, the question often arises: is it better to insulate the walls from the outside or from the inside? Each option has both disadvantages and positive sides. For the first option they are:

High protection from cold, noise, sun and wind;
Will not allow the walls to freeze, because... moisture is released. For the same reason, mold and mildew do not form on structures;
The area of the room inside will not decrease;
It becomes possible to choose any interior design, and also, if necessary, its changes.

Having convinced ourselves of the advantages of this method, we insulate stone walls Houses. Traditional way installation looks simple: the first insulating layer is mineral wool medium density(75 kg/m³), it covers wall unevenness; the second layer is cotton wool high density(from 125 kg/m³), its role is to create a smooth and rigid wall surface, because this will make it easier following works by finishing.

In total, wool for insulating walls from the outside should be a layer of 15 cm. The most best option- when the thermal insulation is between load-bearing wall and external cladding.

In practice, you can insulate a house with stone wool from the outside according to the following plan.

The first step is to prepare the surface. Remove any unevenness from the walls and apply a layer of plaster. Sometimes it makes sense to apply a couple of layers.
Next comes the installation of metal guides; they are secured above the base of the building using anchor bolts.
How to properly insulate a wall with mineral wool? The first layer is installed heat-insulating material(the second one follows immediately). On back side Glue is applied to the slab and it is pressed against the wall. According to the same scheme, all external wall insulation is carried out using stone wool.
Help protect the material from deformation metal corners, which are attached to the external slopes.
Place on top of the layer facing brick, the seams are sealed with plaster.

We looked at the first installation method, called a ventilated facade. There is a second way to insulate walls with stone wool.

The second method is called “wet”. The technology is only slightly different from the previous one. Stone wool: wall insulation:

Both of these methods insulate the house equally well.

Once you have insulated the walls with stone wool from the outside, you need to take care of some important things.

A layer of thermal insulation will increase the thickness of the walls by about 15-20 cm. Therefore, it is advisable to lengthen the slopes, ebbs and window sills so that weather conditions do not spoil the material.

If you decide to lay more than two layers of mineral wool, then this is a bad idea. The more layers, the more air pockets between them. And they lead to a deterioration in thermal insulation properties.

Insulation of walls from the inside with stone wool

Insulation with stone wool from the inside is much faster and cheaper, and even novice builders can easily cope with this task. However, work can only be done in a room where there is no high humidity air. The advantages of insulating walls from the inside are as follows:

Low cost and labor intensive.
You can put insulation not only on the entire building, but also on individual rooms in which you will live. It's quite economical.
It is permissible to work at any time of the year, regardless of weather conditions.

Insulating a house with mineral wool can begin with a calculation required quantity mineral wool. There is a special formula for this. Wall area (m²), multiplied by the thickness of the mineral wool (mm) and divided by the volume of the package. That is, if the area is 15, thickness is 100, volume is 0.432, then you will need about three and a half packages.

Do-it-yourself insulation of walls with stone wool is carried out in several stages. General scheme insulated wall may look something like this: first comes bearing wall, behind it is a layer of vapor barrier, then thermal insulation, and another vapor barrier layer, at the end is the interior trim.

Stone wool for interior walls Suitable for medium density (look for values around 100 kg/m³). Such mineral wool will increase the thickness of the wall by 8-10 cm. Take this into account when carrying out repair work. You can insulate a small room with mineral wool in one day.

One of the methods for implementing the above plan uses relatively simple technology. Stone wool: installation:

Created strong support from metal hangers and profiles. You can put foam tape under it to improve the thermal insulation in the room. If you plan to create two layers of mineral wool, then another additional frame will be required.
Then comes the vapor barrier. If polyethylene was chosen as the material, then between the wall you need to leave a small air chamber. It can be attached either with tape or glue.
Stone wool insulation is placed inside each section of the frame.
Then again there is a layer of vapor barrier. This time it is better to attach it directly to metal profile self-tapping screws.
Plasterboard is placed on top and interior finishing is done.

Stone wool on interior walls, like stone wool on exterior walls, perfectly protects against unnecessary noise. This is especially useful in those houses that are located near roads.

Foundation insulation

Bathhouses usually need foundation insulation, so let’s talk about them first. Why is it necessary to insulate the foundation?

Due to the difference in temperature inside and outside, condensation forms, damaging the base of the bathhouse. Insulation helps to cope with this problem.
Thermal insulation will reduce the amount of wood needed for kindling.
Stone wool can protect against some mechanical damage.

It is better to insulate with mineral wool on the outside of the base, because in this way the foundation will be better protected, and therefore will last longer. The installation technology shown below is suitable for strip foundation. Insulation with mineral wool:

Free the base from the ground. To do this, dig a trench with a depth of one and a half meters and a width of 50 cm.
Afterwards sand is placed and the foundation is coated with bitumen.
Then the insulation is installed. Its thickness is at least 20 cm. Seal the resulting seams with foam. At the corners of the bathhouse, a layer of mineral wool is 1.5 thick. Working with stone wool is easy here.
Stone wool needs additional protection from brick wall(thickness - from 25 cm), which is placed around the perimeter. There will be a blind area at the top.

A few rules and notes for quality work.

How to choose and apply glue to mineral wool

Without correct selection and the use of glue, the insulation may sag, ceasing to act effectively. Stone wool - pretty unusual material, and not every adhesive is capable of providing high-quality adhesion to the wall.

The highest adhesion will be ensured polymer cement compositions. They are sold as a dry mixture similar to cement. There are several well-known brands: “EK THERMEX”, “ERESIT CT190”, “ERESIT CT180”.

Following the instructions on the package, dilute the mixture with water and mix well (repeat after 5 minutes). The solution will retain its adhesive properties for 2 hours.

On flat surface Apply the solution evenly to the walls so that you get 7-8 glue circles. We also apply glue to the back side of the cotton wool (closer to the edges); the surface should be covered with the composition more than half. It is also better to coat the joints. The glue hardens for some time, so it is possible to lay the slab correctly. Attaching stone wool to a wall is simple.

Sometimes, for greater reliability, additional fastening may be required. They can help here anchor bolts or slats fixed to the sheathing.

Stone wool

thermal insulation materials

Stone wool TechnoNIKOL production is divided by area of application. The range includes thermal insulation for plastered and ventilated facades, pitched and flat roofs, floors, walls, etc.

In 2008, TechnoNIKOL Corporation introduced innovative thermal insulation to the market - double-density slabs.

TECHNONICOL products are distinguished by their high heat-saving ability, Fire safety, good sound absorption, hydrophobicity, strength and resistance to deformation. All thermal insulation materials TECHNONICOL brands are produced in accordance with technical specifications, certified and environmentally friendly.

TechnoNIKOL stone wool production plants are equipped with high-tech production equipment.

A Scientific Technical Center (STC) has been created, the main goals of which are: in-depth analysis of the properties of raw materials, materials, finished products, technological processes, information in order to use the most modern and effective methods for production highest quality.

To achieve maximum satisfaction of both external and internal consumers, the company actively uses the principles of total quality management.

Environmental safety is closely related to production safety. The labor protection system at the enterprise is set at the highest level.

Stone wool is one of the varieties of mineral wool. It is produced from gabbro-basalt rocks and is widely used mainly in construction. It is used in the construction of buildings and structures as a heat and sometimes sound insulator. One of the most widespread brands on the domestic market basalt wool is TechnoNIKOL.

This material has earned its popularity thanks to not too high cost and unique technical characteristics.

How it is made

In the production of TechnoNIKOL mineral wool rock pre-loaded into melting furnaces and heats up to a temperature of 1400-1500 degrees. Next, the molten rock mass is poured into a special centrifuge.

Here, spinning tops rotating at speeds of up to 7000 rpm tear it into small fibers. During this procedure binders are poured into the centrifuge. At the next stage, the fibers already impregnated with phenol-formaldehyde resin enter the lamella machine and are formed into a carpet of a given thickness.

Mineral wool of the TechnoNIKOL brand is manufactured by the domestic company of the same name, founded at the end of the last century. On this moment it includes more than 20 enterprises and 120 retail outlets operating throughout the country. Mineral wool from this manufacturer is made from quality materials on modern equipment, and therefore enjoys enormous popularity not only in Russia, but also abroad.

Scope of application

Mineral wool from this manufacturer is used, like any other, most often for insulation of building envelopes: walls or roofs. It is also used for insulating doors, pipelines, attic and attic floors etc.

The main advantage of mineral wool in comparison with another popular insulation material today, expanded polystyrene, is considered to be non-flammability. Therefore, it can also be used to insulate chimneys when passing them through ceilings and roofs.

Some disadvantage of this material is its hydrophilicity. Stone wool absorbs moisture very well. However TechnoNIKOL brand plates in this regard, they are considered quite reliable and of high quality. During the production process, they are impregnated with special hydrophobic compounds, which significantly increases their resistance to moisture significantly.

Types of TechnoNIKOL cotton wool

Today, this company produces several types of basalt wool intended for different purposes. So, for example, for roof insulation the option can be used "Tekhnoruf", and for the facade - "Technofas". Technoacoustic wool is used for soundproofing doors, ceilings, etc. The most popular type of slabs from this manufacturer is TechnoNIKOL Rocklight - universal material with moisture-resistant additives, which can be used for insulation or sound insulation of almost any structure.

Specifications

When purchasing this type of insulation, you usually pay attention to such properties as:

Basically, the characteristics of wool from all TechnoNIKOL lines are similar. Differences exist only in such parameters as density and thermal conductivity. For example, the varieties used for floor insulation are usually rigid and can withstand heavy loads (weight concrete screed). To insulate facades and roofs, softer materials are often used, but characterized by good elasticity. After all, they are installed without fastenings between frame elements. Very dense cotton wool is also used for plaster. But for wrapping pipes, soft flexible TechnoNIKOL wool is usually used.

Coefficient of thermal conductivity

This indicator for TechnoNIKOL stone wool, depending on the variety, can range from 0.034 to 0.047 W/m*S. That is, 10 cm of this material can save heat is as good as 38 cm of timber or 140 cm of brick. Insulation of structures with TechnoNIKOL wool is usually carried out in 1-2 layers. Walls and roofs in middle lane Russia is most often insulated with slabs 10 cm thick. For joist floors and pipes, 50 mm material in two layers is usually used.

Density of slabs

Not only the thermal conductivity coefficient, but also its price largely depends on this characteristic of wool. The fact is that more rigid slabs of the same thickness require more basalt fiber. For TechnoNIKOL stone wool, the density, as already mentioned, can vary greatly depending on the purpose of a particular line. Thus, the universal “Rocklight” and “Technolight”, used for insulating structures that are not subject to loads, have a density of 30-40 kg/m3. For slabs of the Technoflor line, used for insulating floors under screed, it can reach 81-185 kg/m3.

Material cost

The price for dense materials of this brand is approximately 3000-4000 rubles. This is quite a lot, but such slabs are usually used in small quantities. The price for lightweight TechnoNIKOL materials varies only between 500-800 rubles per 1 m³.

Degree of vapor permeability

It's also very important characteristic mineral wool. The easier the slabs allow vapor to pass through, the better the microclimate will be in the rooms insulated by them. Besides, material with a high degree of vapor permeability and itself usually lasts longer. Indeed, in this case, water molecules do not stay on its surface for a long time.

Since Technonikol wool consists of 95-99% air, it can transmit steam very well. The degree of permeability of slabs of this brand is 0.3−0.6 mg/(m.h.Pa). For comparison: even polystyrene foam the best manufacturers this figure is only 0.015−0.019 mg/(m.h.Pa).

Degree of water absorption and fire-resistant properties

Since various types of hydrophobic additives are used in the production of TechnoNIKOL stone wool, it can retain moisture quite well. The water absorption level of this material is 1−2%. This is significantly less than many other brands of stone wool.

Since mineral slabs are a non-flammable material, they can also be used to insulate structures in rooms where there is a high risk of fire. Flammability class of TechnoNIKOL stone wool - N.G. That is, these stoves do not burn at all under any circumstances. Wool fibers of this brand begin to melt at temperatures from 1000 C. Therefore, the manufacturer recommends using it as insulation at operating temperatures up to +400 C.

In the event of a fire, mineral wool can temporarily become an obstacle to the spread of heat and fire. At the same time, it retains other materials that are less resistant to fire. This is actually an important and useful quality. After all, during a fire, when saving people, every minute is often precious.

How long can it last?

TechnoNIKOL stone wool, the price of which is quite reasonable, can retain its excellent performance characteristics for decades even in the most unfavorable conditions. The minimum service life of this material is 50 years. That is, having installed it once, you won’t have to worry about insulating your house for almost the rest of your life.

Such a long service life of stone wool from this manufacturer is explained primarily by its excellent characteristics. Basalt fibers, just like phenol-formaldehyde resins, do not rot or undergo biological corrosion. In addition, unlike expanded polystyrene, mice do not gnaw through their passages.

However, of course, the material will last a long time only if it is installed correctly. Installation of Technoninokol mineral wool, like any other, despite its moisture resistance, only with the use of reliable hydro- and vapor barriers.

Characteristics of Rocklight cotton wool

The price for the most popular type of material of this brand is 350 rubles per sheet with a thickness of 1200 × 600 × 50 mm. The properties of Rocklight cotton wool are as follows:

As you can see, TechnoNIKOL wool has simply remarkable performance characteristics. Since its price is not too high, and it can serve for decades, use it to insulate a house, balcony, garage or suburban system water supply is definitely worth it.
