Glass wool is one of the most inexpensive insulation materials, the effectiveness of which has been tested by time. Modern technologies, used today in the manufacture of the material, have significantly expanded the scope and convenience of its use, strengthened thermal insulation properties. An important advantage that ensures the long-term popularity of glass wool among residential builders is natural composition this insulation.

Production and technical characteristics of glass wool

Glass wool insulation, being a type of mineral wool, has heat-saving characteristics due to its fibrous structure that retains air well. The material, consisting of the finest fibers, is made from a mixture of natural ingredients: sand, dolomite, soda, borax, limestone. IN modern production Glass production waste is also used as feedstock.

Thin glass fibers are pulled from the liquid mass melted at temperatures above 1400 0 C, glued together with a bitumen-based substance and pressed. The resulting soft, elastic layer is cut into mats and slabs of a certain size or rolled into rolls. The finished insulation is packaged in film, which protects it from contamination and getting wet during storage and transportation. After unpacking, the elastic fiber material instantly restores its original volume.

The properties of the components used in the production of glass wool and the features of the technology determine its specifications:

• non-flammability;
• low thermal conductivity;
• optimal vapor permeability;
• good sound absorption;
• resistance to low and high temperatures, chemically aggressive substances;
• natural, harmless to health composition.

Fiberglass layer 5 cm thick in its own thermal insulation qualities identical to 1 m brickwork. The lightweight insulation is easy to transport and extremely easy to install. Glass wool, which practically does not absorb moisture, prevents the development of fungi and microorganisms and is rarely damaged by household rodents.

The main disadvantage of glass wool insulation is the fragility of the glass fibers that form it. The fragility of the material requires caution when working with it, enhanced protection against sharp glass fragments and dust getting on the skin, eyes and nose. It is necessary to carefully insulate the glass wool layer when used to insulate walls from the inside. Compared to expensive, innovative heat-insulating materials, the service life of cheap fiberglass insulation is short - up to 10 years.

Scope of application of glass wool

Despite the large range of modern thermal insulation products on the building materials market, glass wool continues to be in demand. The popularity of insulation is explained by the relative safety of its composition, making it easy for a non-professional to implement self-installation on any surface. The main advantage that determines widespread use in private and industrial construction is low price glass wool.

The scope of application of insulation that is optimal in terms of cost and quality is quite wide. It is recommended to buy glass wool with universal characteristics for insulating metal and non-metallic surfaces located obliquely, vertically or horizontally. The material can be easily laid on uneven, complex shape design, convenient for sealing cracks.

Existing varieties of fiberglass wool based on the thickness of the layer and the fibers that form it, density, and elasticity make it possible to successfully use it for the following operations:

• insulation of any elements building structures: foundation, wall surfaces inside and outside buildings, ceilings, roofs;
• thermal insulation of plumbing, heating, sewer pipes, septic tanks;
• insulation of chimneys, high-temperature surfaces and equipment components;
• noise insulation of mechanisms.

It is profitable to buy glass wool that has all the technical characteristics necessary for certain purposes from the Roofing and Insulation company. Professionals will help you choose the highest quality insulation that best suits the installation and operating conditions. famous brands URSA and TeploKNAUF. When purchasing glass wool in bulk, the price is discounted and free shipping will ensure the greatest cost-effectiveness of construction and the competitiveness of the construction organization.

Glass wool is a fibrous insulation material, belonging to the class of mineral wool. It is considered one of the popular heat insulators.

In this article we will look at the properties, production and use of glass wool.

Glass wool production technology and its characteristics

Fiberglass is made from waste from the glass industry and natural sand. As a result, the material consists of the finest fibers interconnected by a substance.

Thermal insulation products based on glass wool are mats or rolls:

Thanks to the material being pressed several times, it takes up a small volume. When unfolded, they are more or less rigid slabs.

Features of working with glass wool

It should be remembered that when working with glass wool, it turns into fine dust, which causes irritation to the skin, mucous membranes, or enters the lungs, from where it is never removed. Therefore, it is necessary to take care of funds personal protection– gloves, glasses, respirator.

To increase strength, fiberglass materials are reinforced by stitching:

Another disadvantage (besides fragility) is thermal conductivity, which is greater than, for example, polyurethane foam or penoizol. That is, glass wool, as insulation, is worse than the mentioned materials. But it's cheaper.

Advantages of glass wool

• High noise insulation (sellers say so, but I didn’t notice this in my frame extension, although there are four layers of glass wool - 20 cm);
• low density and light weight;
• high strength (again, according to the sellers, who probably just have tongues without bones and heads without brains - what kind of strength does glass wool have if it delaminates in your hands?);
• ease of installation;
• elasticity and flexibility;
• low cost;
• takes up a small volume when packaged;
• ease of transportation;
• not susceptible to mold and rodent attacks;
• modern cotton wool is relatively safe (the key word here is “relatively”).

I would like to add a comment.

The expression regarding the safety of using glass wool does not inspire confidence at all.

We should once again remind you about safety precautions:

In case of contact with skin, try to wash off with water without scratching the skin; otherwise the fibers will go deep under the skin.

If fibers get on the mucous membrane, consult a doctor immediately! (I mean, that’s what doctors advise, but in reality, it depends on what kind of mucous membranes you have: you yourself wash your eyes with a large amount running water, you don’t need a doctor for this; and no doctor can remove fiberglass dust from the respiratory tract, so why? Behind the wallet...).

1). The use of thick work clothes is mandatory.

2). During installation, the layer of wool should be covered with another material to prevent dust from penetrating into the room where there are people.

3). If the insulation is indoors, then it is good to vacuum the room after work.

The main disadvantages of glass wool

Actually, they have been discussed above exhaustively; we will not pound the waters.

My review of Knauf glass wool

I would like to leave a review in this article dedicated to such material as Knauf fiberglass.

Packaged in rolls:

Or mats:

I used cotton wool produced by mats. It's called "ThermoPlate 037" and is a light series glass wool.

Characteristics:

Mat dimensions 5 x 60 x 125 cm,

Thermal conductivity coefficient is 0.037.

There are 24 mats in the package, the total area of ​​the mats in the package is 18 m2 (you need to buy with a reserve if you want to insulate in two or three layers. With what margin? It is believed that 5...10% is spent on trimming any material, of these numbers and estimate).

Manufacturer of the material: KNAUF Insulation LLC, Stupino, Moscow region.

Insulation was for the walls frame extension To home. I placed glass wool between vertical posts and ceiling beams:

My review of the material in action:

1. It's great for cutting sheets; it can be cut with both a sharp knife and scissors (large tailor's scissors, not manicure scissors :)).
2. I confirm that rodents will definitely not settle in the glass wool (the packaging was in a room accessible to gray animals, but they did not settle into the insulation itself).
3. The density of this type of Knauf is low, so the material is not fully suitable for thermal insulation of vertical structures. Unfortunately, the density is not indicated on the packaging. It is better to inquire about the density of glass wool in advance on the Internet or other sources, so as not to get a “pig in a poke” (this is not the kind of cat that will drive away mice :)).
4. Despite the manufacturer's assurances that cotton wool is formaldehyde-free and does not have a pungent odor, in reality there is an odor. Therefore, it is better to work with a respirator, and interior walls, again, make it airtight.

I note that using rolled Knauf is much more convenient for horizontal floors. Firstly, the convenience of rolling on the surface. Secondly, with multi-layer insulation, the layers will be without joints, and, therefore, without cold entering the room insulated with such material.

The overall assessment of the material is quite good, and in the absence best alternative I would use it in the future. But there is an alternative, which I’ll tell you about someday...

Application of glass wool

Thanks to its efficiency and versatility, this thermal insulation material It has wide range applications in construction. Glass wool is more suitable for insulating attic and interfloor, that is, horizontal floors. Certainly, vertical structures it is also possible to insulate (see photo above; the fact is that cotton wool does not creep on unplaned boards, you just need to make the distance between the boards smaller by 1.5...2 cm of the width of the insulation).

Which insulation is better: glass wool or mineral wool?

If I had to choose between glass wool and mineral wool, I would still choose our building material- glass wool. One of the most important advantages that especially attracted me was that there were no mice or other living creatures in it.

More. With the same thickness of glass wool it is 10...15% warmer basalt wool and cheaper. Glass wool has longer fibers than basalt wool, so less glue is used in the manufacture of glass wool, which means less formaldehyde.

Mineral wool should be used only where it is possible to put a reliable layer against the penetration of formaldehyde into the living space. In general, it must be used wisely to insulate facades, because health (lack of it) is an even more expensive thing than building a house.

I made my choice, I hope that my review will be useful to you, and you will also make your right choice.

glass wool technical characteristics

Thermal insulation materials are used very often in construction. Each of them has individual technical characteristics, not least of which are the dimensions of these products. It is known that only 5 cm of insulation can successfully replace 20 cm concrete base. Having studied the insulation, the dimensions of which correspond to design features buildings, you can build warm and comfortable housing, erect a roof, foundation and walls.

There are quite a large number of thermal insulation samples. The most popular is basalt insulation; the size of its slabs corresponds to standard norms, during installation it is practically not deformed. Extruded polystyrene foam is an incredibly shrink-resistant raw material that can withstand high pressure, does not absorb dust and moisture. Having a thickness of 2-3 mm, it surpasses other samples in terms of quality. Insulation with mineral wool is achieved due to air pores located in the space between the fibers.

Solid base insulation most often has a slab configuration. Their thickness may vary: the minimum value is 20 mm. Standard sizes slabs are equal to 1250x600. Some models have some differences in dimensions: 1000x600x50, 1000x500x30. Flexible versions of such sources are produced in rolls of different lengths; accordingly, the small height of the product indicates its larger volume in such a package. Therefore, the dimensions can have the following coefficients: 9000x1220x50, 3900x1200x150.

Types of mineral insulation

1. Fiberglass.

This insulator is lightweight, has a soft coating and is absolutely safe for humans. It is made by melting glass and has elongated, massive fibers. This insulation is produced in the form of rolls and slabs. Even under the influence of unfavorable external factors glass fibers do not change their properties, sizes and configurations.

Plates from this raw material are produced by gluing with synthetic resins. Rigid and semi-rigid bases differ in the following dimensions: 1000X1500X50-70 mm. Fiberglass strips and mats have the form of bags, treated on both sides with glass wool and stitched with cotton threads. Such bases are most often used for pipeline insulation. The dimensions of the mats correspond to the following parameters: length – 1400, width – 500; 900; 1000 and 1500, thickness – 30; 40; 50; 60; 70 and 80 mm.

1. Basalt insulation.

Such insulators are produced by melting basalt and minerals of similar composition. Their external signs similar to fiberglass raw materials. The structure of basalt threads makes it possible to reduce mechanical loads. The use of such samples in practice contributes to high-quality insulation of facades, walls, ceilings, pitched roofs. Basalt insulator prevents moisture from penetrating into the room and does not allow extraneous sounds to pass through. Therefore, there is no dampness or mold in the premises.

Taking into account the average performance of thermal insulation material, their dimensions correspond to: 1200x600x100; 1000x600x100; 1200x600x50; 1000x600x50 mm. The difference in such indicators is determined by the differences in the requirements of each manufacturer, whose standards may differ slightly.

1. Mineral wool.

Mineral wool insulators are produced in the following versions: some are in the form of slabs, others are produced in the form of rolls.

Both tiles perform the same function, determined by the conditions installation work. Insulation in the form of rolls is convenient for rooms with large areas.

To ensure convenience during the installation of thermal insulators, dimensions are established for each brand of product. The dimensions of mineral wool slabs are 1000-1200 mm in length and 500-600 mm in width.

Polymer-based materials

Heat insulators of this type are actively used in damp rooms. The disadvantage of insulation from the polymer category is the low degree of fire resistance.

1. Foamed polystyrene foam.

Such insulators contain granules, the size of which corresponds to 2-8 mm, and a flame retardant foaming agent. Insulation boards of this type have virtually no weight: lightweight blocks can be easily cut to the required sizes. During the heating process, the granules increase in volume. A layer of this material 5 cm high laid on the surface will provide high-quality insulation of the room, hydro- and sound insulation. Ready blocks made of expanded polystyrene have a length from 800 cm to 6000 cm. The average width is 1200 mm.

1. Extruded polystyrene foam.

This material is produced in the form of slabs, their traditional sizes are: 1250x600. They are very easy to cut and easy to install. Another name for this insulator is penoplex. If you want to achieve high thermal insulation coefficients and absorption of extraneous noise in your home, it is recommended to use thicker material. You can find out these values ​​from the markings presented on each of the packages: 15, 25 and 100.

A remarkable advantage of such plates is self installation these samples. For indoor installation, sheets with a thickness of 15 mm are often used. A higher insulator helps reduce the area of ​​the room. For this reason, its values ​​are determined by the dimensions of the insulated object.

The length and width indicators for such slabs are standard: 60 cm and a length of 120-240 cm.

1. Foamed polyethylene foam.

This is a heat-insulating material from the category of polymers, produced by foaming with chemical and physical gas-forming agents. When installing it, there is no need to use a vapor barrier layer. It is produced in the form of rolls, the width of which is 0.5-1.5 meters, thickness - from 2 to 15 mm.

1. Polyurethane foam.

It looks like infusible plastic with a mesh base. Used as insulation for windows, doors, roofs and external walls.

Despite the abundance of various materials, glass wool has held a high position among for about 150 years. This is due to its low cost good characteristics.

Glass wool is most often made from broken glass, so care must be taken when using it. However, this inconvenience is compensated by excellent sound and heat protection functions. Thanks to these qualities, it is used not only for insulating buildings, but also for laying pipes, for insulating vehicles, in cooling systems and many other fields of activity.

This insulation is a type. However, both materials have significant differences in characteristics.

What are the differences between mineral wool and glass wool?

Both materials are insulation with a fibrous structure. However, the difference between them is quite big:

• softer and more elastic than mineral wool. Has good hiding power, which allows for insulation large areas. It is also easier to transport and costs much less.
• Mineral wool absorbs less moisture, as a result of which it has a lower percentage of shrinkage. The heat resistance index is higher than that of glass wool.

Thus, when choosing between these materials, it is necessary to determine the conditions in the room to be insulated. For example, it is better to insulate the attic with glass wool due to its covering power, and the kitchen area with high humidity it's worth insulating mineral wool. When the budget issue comes up sharply, glass wool is the leader.

What characteristics does glass wool have?

Glass wool is produced in accordance with GOST 19170 2001. According to the classification GOST 31913-2011 and the EN ISO 9229:2007 standard, it is an insulation material.

It acquires its properties due to its fibrous structure:

• Thermal insulation. The air between the fibers provides insulating properties.
• Soundproofing. Glass wool fibers reflect sound well, resulting in high levels of this property.

Thick and long fibers of this material are located parallel to each other, due to which very high strength and elasticity are achieved. The strength of glass wool surpasses even steel wire. In addition, glass wool has the following characteristics:

• Increased resistance to vibrations;
• Does not affect structures;
• Isolates unevenness and complex elements due to its elasticity and high compressibility;
• Not suitable for rodents;
• Fungal infections and mold do not grow.

Also, this material does not age, does not corrode when in contact with metal, and is suitable for use at temperatures up to – 60 degrees.

No material can be perfect. Negative characteristics include excessive fragility and increased moisture absorption. To protect against fragility, it is necessary to use special clothing and protective equipment (goggles, respirator, gloves), and to protect against moisture, glass wool is impregnated with various compounds.

Can glass wool catch fire?

This material does not burn, does not support combustion and does not spread it. Holds up perfectly high temperatures, keeping all your positive properties. Glass wool begins to sinter at temperatures above 500°. The upper limit at which the material begins to melt corresponds to the resins contained in the material. When the moment of their burnout comes, the glass wool begins to melt.

A positive point is the lack of release of toxic substances under the influence of fire. Thus, even melting glass wool remains safe in this regard.

How is glass wool produced?

Production is not particularly difficult. The main thing in this is strict adherence to the recipe and careful compliance with GOST. In addition, even cullet used in the production of insulation is strictly regulated by GOST R 52233-2004.

Main stages of production:

1. Mixing. For 80% glass add 20% sand or other material (soda, dolomite, limestone).
2. Melting. At temperatures above 1400°, the mixture melts.
3. Fiber Formation. The alloy is treated with a polymer aerosol, resulting in the formation of fibers that move along the conveyor.
4. Polymerization. The temperature is cooled to 250°, resulting in a bright yellow finished material.
5. Final stage. The glass wool is cooled completely, cut into required dimensions, packed in mats or rolls.

Production waste is a raw material that is recycled.

How is glass wool used?

Glass wool has a wide range of applications. It is used in aviation, pipeline laying, and the automotive industry. For solutions various tasks necessary various options this material.

For this reason produce glass wool:

• Rolls;
• Slabs - soft, hard, semi-soft options;
• Matami is only the soft type;
• Rolls reinforced with reinforcement;
• Foil products;
• Cached isolation.

At the same time, rolls are necessary for horizontal insulation, cached insulation is used for pipeline insulation, and mats or slabs are widely used in construction.

The slabs are joined along the length in two ways:

• Groove - tongue;
• Groove - ridge.

Fiberglass is also produced. It is used for protection from wind.

How to work with glass wool correctly?

To ensure that there are no problems during operation, you must:

1. Before starting work, straighten and clean the glass wool from crumbling particles;
2. When insulating ceiling you can use lathing. If there is no sheathing, apply waterproofing.
3. Apply glue, press glass wool to the surface, hold for several minutes.
4. Use special clothing and protective equipment (gloves, respirator, goggles).
5. Upon completion of work, treat clothing, hands and face.

What is better for floor insulation?

In addition to glass wool, expanded clay is used for floor insulation. The choice of material depends on specific situation and owner preferences. Often the choice falls on glass wool due to its lower price.

However It is worth remembering about its properties:

• In areas with high humidity(kitchen, bathroom) it is better to prefer expanded clay;
• If a large load is expected on the floor in the room(living room, for example), glass wool will also not be effective.
• In low traffic areas(bedroom, attic) glass wool would be a good option.

Thus, in dry rooms with minimal floor load, glass wool is a good and inexpensive solution.

How to recycle glass wool?

Glass wool must not be disposed of with household or construction waste.

The following methods are used for its disposal::

1. Burial at a landfill;
2. Use in road construction;
3. Application in brick production;
4. Using the residue after burning it;
5. Grinding to the smallest particles for reuse in glass wool production.

For proper disposal, you must either contact the manufacturer or special service for the recycling of glass wool.

Does glass wool affect health?

You can often see on the Internet different opinions. Some argue that she is very dangerous, others come to her defense.

Let's sort it out individual cases:

1. During operation. Glass wool is covered with other materials, which prevents particles from getting into the air. Harmful substances does not evaporate. Does not burn. Conclusion: there is no danger to humans.
2. During work. Tiny particles can get into a worker's lungs, eyes, clothing or skin. There are no other dangers. Conclusion: there is a health risk.

To avoid risk when working with the material, Some rules should be applied:

• Work exclusively in tight overalls that cover the body as much as possible;
• Use personal protective equipment - respirators, gloves, goggles;
• After work, you must wash your hands thoroughly, and only then wash your face;
• In case of accidental inhalation or contact with eyes, rinse with plenty of water and seek immediate medical attention. Rubbing the affected area is strictly prohibited!

Compliance with these rules and care when working with the material will reduce the risk to a minimum.

What to do if glass wool gets on your skin or clothing?

Removing glass wool from clothing is challenging task. For example, it is almost impossible to remove it from a woolen product. In this case, you should contact a dry cleaner. If it doesn’t help, the only thing left to do is dispose of it. For this reason, protective clothing when working with glass wool should be made of dense material. But it is not all that bad.

To clean clothes you need:

1. Vacuum thoroughly.
2. Rinse in large quantities water 3 – 4 times, the last time under strong pressure of water. rub, use washing machine, washing with other things is prohibited!
3. Dry.
4. Vacuum again.
5. Extend. It is best to use a solution laundry soap, but you can use any powder. Rub very carefully, machine wash is prohibited.
6. Dry.
7. Contact the dry cleaner stating the problem and describing the measures taken if these steps did not help.

If clothes can be thrown away in a pinch, then the situation with skin is more serious. Essentially the actions will be similar:

1. Rinse your hands under high pressure of water, do not rub.
2. Shake dry hair thoroughly;
3. Rinse your face with plenty of water;
4. Take a cool shower under strong pressure. Friction, washcloth, soap, hot or warm water prohibited.
5. Dry naturally without using a towel.
6. Take a shower using a washcloth and soap carefully. The water must be cool!

If some place remains inflamed, you can use the following remedies:

• Apply a wet cold towel for a while;
• Aloe – juice or inner part of the leaf;
• Milk;
• Calendula solution.

If the inflammation does not go away and the itching persists, you should consult a doctor.

What quality of material do the main manufacturers produce?

There are quite a lot of glass wool manufacturers on the modern market. Let's consider the quality of products of some brands:

1. Knauf– glass wool is produced using German technology. The quality is high. Full compliance with Russian standards.
2. Ursa– the material is intended for insulating the frame, roof, facade. The quality is high. Increased security.
3. Hemah– convenient transportation thanks to 7-fold compression. Insulation of roof and ceiling. World class quality.
4. Isover- for a variety of jobs. 2x compression. Quite high quality material.

The most popular brand under which glass wool insulation is produced is . This material is in demand due to its low price, but there are some types of work for which it is not recommended to be used. For example, for insulating concrete floors under a heavy layer of screed or for insulating walls from the outside according to the method wet facade.

Characteristics and scope of application of glass wool insulation

Glass wool fibers are soft and long.

Glass wool insulation is environmentally friendly pure material, it is made from glass production residues. As you know, glass is made from sand, which is absolutely chemically inert, so thermal insulation does not affect any chemical reactions. Its density is quite low, and accordingly the weight of one cubic meter is also small.

Main characteristics of glass wool insulation:

• thermal conductivity – 0.032 -0.044 W/m*C;
• hygroscopicity – very high;
• degree of flammability - NG;
• Available with or without foil.

High hygroscopicity, in other words, the ability to absorb moisture, is the scourge of glass wool, which must be combated by all available means.

Therefore, the material must be protected with vapor barrier and waterproofing, the installation method of which we will talk about a little later. The range of application of this material is quite wide. Glass wool is used to insulate roofs, walls and horizontal ceilings. There are even varieties that can be applied to thin layer plaster. At the same time, due to its low density, instead of glass wool, it is better to use basalt wool to insulate external walls using the wet facade method.

But this is not the entire list of works for which glass wool insulation is used. Technical characteristics allow it to be used for chimney insulation to minimize the formation of condensation in them. This procedure must be carried out on sections of the pipe that pass through unheated room and on the street.

Glass wool installation methods

Glass wool is placed between the guides.

Glass wool insulation is possible both indoors and outdoors. External work includes thermal insulation of the ventilated facade and insulation of the chimney. The most important thing when arranging a ventilation façade:

• the wall is leveled;
• the sheathing is stuffed;
• glass wool is laid - depending on the type, the material is glued or placed apart between the bars;
• Films and membranes are not needed between the glass wool and the wall;
• a wind barrier is laid on top of the insulation; it can be replaced with a diffusion membrane;
• the second level of sheathing is filled in and the exterior trim is attached.

There is no special technology for insulating a glass wool chimney. You just need to wrap the thermal insulation around the pipe and cover it with foil, which will serve as waterproofing and protection from IR rays. The foil should be wound with a good overlap and start from the bottom.

When it rains, all the moisture will go down and will not get into the insulation layer; if you start wrapping the pipe with foil from above, all the water will seep inside. The foil is fixed with aluminum wire, which is soft enough and does not rust.

Inside, glass wool is used to insulate floors, walls and floors if the attic is not heated. There are some differences in installation, which lie in the selection of the desired film and its installation. To insulate wooden house You must first lay down a diffusion membrane and then put insulation on it. You can also cover the glass wool with a vapor barrier on top, but this condition is not necessary, since warm air, saturated with steam, rises upward.

Therefore, if insulation is planned attic floor, then on the side of the room you need to lay a vapor barrier that protects the insulation from moisture getting into it. It is possible to leave the glass wool open on top; if you want to further protect it from liquid ingress, then use diffusion membranes.

Glass wool strongly absorbs moisture, so it must be covered with a vapor barrier.

• the sheathing is being erected;
• thermal insulation is installed;
• creep vapor barrier;
• the structure is sewn up with finishing.

Two options are allowed - with and without a gap between the film and the finish. Both are correct, but having a gap is preferable. The gap is of particular importance when insulating the roof. The correct technique is as follows (layers from the inside):

• vapor barrier;
• glass wool;
• waterproofing;
• gap;
• roof finishing.

If the technology is not followed, problems may arise during operation. Although the cause of troubles can sometimes be factors that are beyond your control.

Possible problems with glass wool and their solutions

Let's consider what problems may arise: their causes and solutions. Problem #1 – glass wool is wet. The reason for this may be the erroneous conclusion of thermal insulation between two vapor barrier films. This can also be caused by laying the diffusion membrane on the wrong side. In addition, moisture can get into the insulation due to a leak in one of the film layers. The solution to the problem is to disassemble the thermal insulation cake, give the glass wool time to dry and do everything again, following the technology.

Problem No. 2 – the glass wool has shrunk. This happens when walls are insulated with a material with a very low density without the use of dowels with a wide cap. The solution is to add insulation to the voids.

Problem No. 3 – there are mice in the glass wool. In fact, the situation is very common and despite all attempts to remove rodents the best option All that remains is to get a cat. It is not recommended to poison mice, as they usually die in their burrow. This ensures a stench throughout the entire house.
