What is Izolon: features and application of different types of fabric

Last time we talked about what liquid ceramic thermal insulation is, its characteristics and areas of application. Today we will talk about the already familiar material made of polyethylene foam. We will reveal effective and quick methods for insulating floors with Izolon, as well as walls and ceilings. Let’s say in advance that to obtain a high-quality thermal insulation layer, you need to use thick insulation, from 50 mm or more. Although the thermal conductivity of Izolon is quite low, with such a small thickness, frankly speaking, it is impossible to properly insulate. At the same time, the material has other useful qualities.

Description of material

Isolon thermal insulation consists of artificially foamed polyethylene, which has the form of small cells or pores. Increased thermal insulation characteristics are achieved thanks to the porous structure. Using it, various surfaces and entire structures are insulated and waterproofed. The finished material can be in the form of a sheet, tape, block or roll.

The main scope of application is hydro, sound and thermal insulation. It is also used in household tasks, as it has better characteristics compared to similar products. The special structure makes isolon a durable and wear-resistant material.

It is often used in conjunction with other insulators. For example, if the task is thermal insulation of the surface, it is combined with polystyrene foam or expanded polystyrene. This “pie” allows for high-quality insulation of walls, interfloor ceilings and loggias. It also serves as an insulating coating when screeding floors. It is also used in car production - it insulates bodies and protects metal parts from corrosion.

Composition and technical characteristics

To make isolon, polyethylene is foamed, which explains its structure - air pores closed in the synthetic “body”. Despite its elasticity, the material is quite soft, so it is convenient when working with geometrically complex surfaces. When making isolon, a thin foil layer of aluminum is made, the task of which is to reflect heat back into the room. As a result, it is possible to reduce the thickness of the insulation layer itself (the usual thickness for other products is 50-100 mm). The initial thickness of isolon is 2 mm, but if necessary it is increased to 100 mm. It all depends on the area in which it is used. For example, to insulate a balcony, you will need insulation 20-30 mm thick.

Depending on the production method, there are two types of isolon: NPE and PPE (non-crosslinked polyethylene foam and crosslinked). They will be discussed in more detail below, and the technical characteristics of both options are in the table below.

Main varieties

Izolon PPE
Thermal insulation Izolon, depending on the structure, is divided into several types.

Izolon PPE

The cross-linked material is made by joining chains of carbon and hydrogen into a 3D molecular network. It is difficult to break bonds, so the main characteristic of Izolon PPE is increased strength. Cross-linked insulation has different markings:

• 500 and 500 L. Produced on the basis of polyethylene, physically combined in a vertical oven. The structure of the sample is ligation in the transverse direction;
• 500 HP. Material with a similar structure, manufactured in horizontal kilns;
• 500-300. The production process involves foaming the polymer and adding chemical elements to it in horizontal furnaces.

Air bubbles remain in the composition of PPE, so it is light and characterized by low density.

Izolon NPE

Izolon NPE
is an extruded polyethylene foam with a non-crosslinked structure. The polymers acquire a foam state after the introduction of a blowing agent, which ensures closed pores with an even structure and a density of 26 kg/m3. The thermal conductivity of NPE is 0.040 W/m*K - 1 cm of material can replace 1.4 cm of Penoplex insulation, 16 cm of brickwork and 5 cm of beams.

Features of uncrosslinked Izolon include:

• high-quality steam and moisture protection - closed cells prevent water absorption along the entire perimeter of the sheet;
• providing sound insulation;
• environmental safety - fren gas is not used for foaming;
• compatibility with all types of building materials;
• durability and resistance to rotting thanks to the polymers in the composition.

NPE is easy to cut and lay in a special crate.

Foil

Foil insulation
A foil film 14 microns thick is applied to the material on one or both sides. The coating helps reflect 97% of the heat and therefore the thermal insulation works like a thermos. Any room can be insulated with foil isolon due to its properties:

• vapor permeability of 0.031 - 0.04 mg/m*h*Pa - walls and finishes do not become damp or moldy;
• minimal moisture absorption - moisture does not penetrate into the material and condensation does not form;
• sound insulation characteristics - does not absorb sounds from 32 dB;
• light weight - ensures quick cutting and no reinforcement during installation.

Foil-coated Izolon can be used indoors.

Specifics of Izolon

Izolon is produced by foaming polyethylene with small cells and closed pores

Izolon based on fine-cell polyethylene foam has high thermal insulation properties and low weight. Some modifications are made with single- or double-sided lamination with aluminum foil. The thickness of the coating is 14 microns and provides waterproofness as well as reflective properties.

The material also has a reinforced frame in the form of a propylene mesh. The basis of Isolon is self-adhesive or glueless. There are combined varieties with foil and adhesive base on sale. To prevent the sheets from sticking together during transportation, a protective film is applied to the adhesive surface.

Production stages

The isolon production process is divided into three main stages:

When producing foil-coated isolon, at the last stage, thin aluminum foil is glued to a layer of foamed polyethylene using the lamination method.

Izolon PPE is more resistant to aggressive environments. Its heat, sound and moisture resistance is higher than that of the non-stitched version.

In addition, the following types of foil insulation are distinguished:

Thermal insulator with foil on one side

The choice of material thickness depends on the purpose of its use. For additional insulation of the floor, foamed polyethylene with a thickness of 2-4 mm is suitable, for absorbing sounds in the room and insulating the roof - 4-10 mm, for floors between floors - 10-30 mm.

Note: The use of aluminum foil increases the heat and light reflecting properties of isolon, increasing this figure to 98%.

Sources of cold

Even if during construction you spared no expense on thermal insulation of the roof and foundation, there are other areas through which heat can escape:

• First of all, these are entrance doors and windows;
• Balcony, if available.
• Walls - in the event that the builders “scraped” and did not treat the work process with due professionalism.

Minimizing heat loss and maintaining comfort in your home directly depends on high-quality insulation. In addition, good thermal insulation will significantly save your money on heating costs, since the current price of energy is quite high.

Foil material is suitable for baths and saunas, retains heat perfectly and maintains the required temperature

Preparing for home insulation

The material described in this article is supplied to the domestic market, packaged in large rolls. Based on this, before purchasing an insulating element, you should calculate in advance how much insulation will be required during the construction process in order to efficiently insulate the house with isolon. In order to properly insulate the walls of a building, you will need a lot of aluminum tape. This material will help connect pieces of insulation to each other, as well as increase the reflective level of isolon. Correct joining of the insulating element will allow you to retain heat in the rooms, while achieving a high level of vapor barrier. Methods of using isolon Installation of this insulation can be done in two ways: between both walls or between the interior decoration of the room and the interior wall. In any of the presented options, insulating a house with isolon will help to cope with its task perfectly, protecting the house from unwanted heat loss.

How does insulation work?

Heat is transferred through infrared rays, invisible to the human eye, but capable of heating opaque objects. In addition, this radiation can also be reflected from mirror surfaces.

Izolon brand insulation is based on this principle. Being located between two walls, or between the finishing and the outer wall, isolon reflects infrared rays back into the room, radically reducing heat loss, and therefore increasing the efficiency of heating systems and reducing the cost of maintaining the desired temperature in the room.

Last time we talked about what liquid ceramic thermal insulation is, its characteristics and areas of application. Today we will talk about the already familiar material made of polyethylene foam. We will reveal effective and quick methods for insulating floors with Izolon, as well as walls and ceilings. Let’s say in advance that to obtain a high-quality thermal insulation layer, you need to use thick insulation, from 50 mm or more.

Advantages and disadvantages

Do-it-yourself insulation of a bathhouse with isolon: the method of specialists

This material is made on the basis of foamed polyethylene. It has different thickness and appearance of the coating. It also reflects the heat emanating from the walls.

Izolon is resistant to sudden temperature changes. It retains its appearance and properties at temperatures from -85 to +125 C.

the material has a different texture: uniform or cross-linked. Choose any option for insulating the bathhouse.

The advantages of isolon are:

• heat retention up to 90%;
• minimal reduction in steam room area;
• it is possible to independently insulate the walls of the steam room with this material;
• Isolon is resistant to moisture;
• affordable cost of material;
• no corrosion;
• When the material heats up, it does not produce harmful substances.

But this material also has disadvantages:

• sizing of joints is required;
• there is exposure to mechanical damage.

It is best to choose roll insulation for a bathhouse. It is much more convenient to work with him.

Advantages and disadvantages

The porous structure with cross-linked molecules provides the following properties of the Izolon material:

• Excellent ability to retain heat and sounds. A polymer with a thickness of 1 cm in terms of thermal insulation properties corresponds to 15 cm of brickwork or 5 cm of solid pine timber; slightly superior to polystyrene foam and mineral wool (they will need 1.5 cm).

Foamiran is a decorative variety of PPE Source shopify.com

• High level of waterproofing. Thanks to the closed pores filled with air, the material practically does not absorb moisture and remains vapor-tight.
• High inertness in contact with oil and petroleum products, with chemical compounds; Izolon is compatible with most building materials.
• Impressive service life: manufacturers talk about 80-90 years without loss of performance properties.
• Health safety. The material does not emit substances that are hazardous to health or cause allergies, does not rot and does not become a haven for microorganisms and fungi.

Builders note the following advantages of Izolon:

• Elastic and lightweight insulation makes installation simple and quick. It is easy to process - just a sharp knife is enough to cut the workpieces to the desired size.
• Reasonable price and no waste make it an economical insulation option.
• The polymer is resistant to atmospheric factors and solar ultraviolet radiation, so it is used for facade (external) insulation.

The following features of foil insulation can turn into disadvantages:

• Low strength. It is also typical for other insulators of this class: any of them is easy to pierce, so care is required during installation.
• Foil materials require a ventilation gap of 1-2 cm; this helps to avoid the formation of condensation, but at the same time increases the cost of insulation.
• With constant high humidity, the aluminum coating begins to corrode, and over time the thermal insulation ceases to perform its functions.

Amateurish technology

The origins of balcony disasters originate in the following statements:

• “for normal high-quality insulation of a loggia, in order for it to be as warm as in an apartment, ordinary insulation with a thickness of 10 millimeters is enough
  “;
• using expanded polystyrene is “ the height of stupidity and inefficiency
  ,” since isolon “
  has higher thermophysical characteristics
  .”

Based on these stupid tips, people are sold a miracle technology for insulating balconies and loggias, which is built according to the following scheme:

The author of the above statements and thermal insulation technology is a person who can speak confidently on camera, but does not understand construction and repairs.

We called his technology

Amateurish

. After all, any competent builder knows that 1 cm of isolon is extremely insufficient for insulating balconies and loggias. Further in the text we will confirm our words.

REMINDER. Expanded polystyrene (foam) or mineral wool are often used for thermal insulation of building structures. Both of these materials retain heat approximately equally, but the main thing is that they are laid in layers not 1 cm thick, but on average 10 cm thick. Perhaps this is because they are really much worse than the super insulation isolon and are not capable of protecting the balcony from frost with the thickness of a finger? But is this really so?

Argument No. 2. Super insulation is a myth

The first indicator of thermal efficiency - the ability of a material to retain heat - is the thermal conductivity coefficient, which is denoted by the letter "?" – lambda.

? (W/m°C) is the amount of heat in watts (W) passing through a layer of material 1 m (meter) thick if the temperature difference between its opposing surfaces is 1 °C (degree Celsius).

• How ? The smaller the better the insulator.
• ? depends on the nature of the material and does not depend on its thickness. Coefficient of thermal conductivity ? is a laboratory value that is measured on samples of the same size.

Place two frying pans on the fire - one with cast iron and one with plastic handles. Soon the handle of the first frying pan will become scalding hot, and the handle of the second will remain cold. This is a result of the fact that metal has a much higher thermal conductivity coefficient than plastic.

Let's compare the lambdas of several popular insulation materials. Data about them can be found on the websites of thermal insulation manufacturers, as well as in regulatory documents (we took higher values ​​from SP 50.13330.2012):

• Izolon (foamed polyethylene) – 0.036-0.05;
• EPPS – extruded polystyrene foam (TechnoNIKOL) – 0.030-0.034;
• EPS – expanded polystyrene, polystyrene foam (GOST 15588.2014) – 0.035-0.059;
• Stone wool (Rockwool) – 0.035-0.048.

CONCLUSION: Coefficients? all materials are from approximately the same range. Statement that isolon “ has higher thermophysical characteristics

” – illiterate.

How to insulate a house inside?

Work on insulating a room from the inside requires proper preliminary preparation of the wall surface. First of all, all coverings are removed down to the base of the wall (it is best to remove the plaster as well). Dirt and dust are thoroughly removed. Next, the wall must be thoroughly dried. To do this, it is recommended to use directional heaters or a heat gun.

The next stage is treating the wall with an antiseptic composition . After this, the surface is primed using deep penetration mixtures. To level a concrete wall, such preparation is usually sufficient.

In the case of brickwork, you will have to level the surface before insulation. Usually a layer of plaster up to 2-3 cm thick is applied. Ingredients are added to the plaster solution to increase water resistance (for example, liquid glass).

Thermal insulation is installed on the wall in two main ways: on the frame and with glue. The choice depends on several factors.

Insulation on the frame

The essence of the technology is to attach racks made of timber or a metal profile to the wall, between which thermal insulation is placed. Sheet materials are placed on top of the frame and preparation for the finishing coating is provided. The work is carried out in the following sequence:

1. Laying waterproofing (polyethylene film).
2. Installation of vertical posts in increments of 40-60 cm. They are attached to the wall with dowels.
3. Installation of horizontal reinforcing bridges (if necessary).
4. Laying insulation (sheets, slabs, rolls), without allowing a gap between the insulation and the frame elements. Fastening is provided using dowels, self-tapping screws or a furniture stapler.
5. Installation of leveling covering made of plywood, chipboard or other materials. A ventilation gap is created between the insulation and the coating.

Glue mounting

The second method of insulation is based on a sealed installation of thermal insulation. In this case, careful preparation of the wall surface is necessary. The insulation is glued to it, excluding air gaps where moisture can accumulate. In this way, foamed polymers and rolled materials can be attached. To increase reliability, additional fastening with dowels is carried out.

The choice of insulation method depends on its type, wall design, and the size of the room itself. Frame technology is highly reliable, but “eats up” more usable space.

Methods for laying isolon

When insulating the walls of a house from the inside with the help of such a reflective heat-insulating material, it can be laid both between two walls and between the outer wall and the internal finishing surface.

In both cases, there will be a reflection of not only the heat coming from inside the room, but also the cold coming from outside. This is achieved by foiling the insulation, which can be one-sided or two-sided.

When choosing an option for installing isolon, it is necessary to take into account the architectural features of the building design.

When working with isonol, it must be remembered that the greatest effect from this heat-insulating material is obtained if there is an air cushion between the insulation and the wall. It should not be more than 15-20 mm.

To create an air cushion, you need to stuff, in a checkerboard pattern, slats 1 to 1.5 meters long.

The distance between them should be no more than 1 meter.

The insulation should be attached to them using small nails or a furniture stapler. The joints between pieces of isolon must be carefully taped with an aluminum stapler.

After the insulation is properly strengthened, slats are nailed onto it, onto which the finishing layer of the inner wall will then be mounted.

Isolon laid in this way will prevent heat loss.

The air gaps created will promote thermal reflection. They will send cold air back outside, and warm air into the house.

To achieve maximum effect, it is better to give preference to isonol foiled on both sides.

Features of indoor wall insulation

In principle, the possibility of insulating walls in residential premises from the inside raises serious and fair doubts among many experts. Internal thermal insulation (with insufficient external insulation) can cause undesirable effects . However, it is not only not prohibited by regulatory documents, but in a number of cases it is recognized as a necessity.

When is it important to insulate from the inside? The following reasons for installing internal thermal insulation of walls are recognized as objective:

• the apartment is located in a building in which any external changes are prohibited (central and historical areas of the city, buildings of architectural value, etc.);
• technical difficulties in installing external thermal insulation (for example, high-rise buildings);
• the presence of special zones - expansion joint, border with technical premises (for example, an elevator shaft), various specific structures and architectural elements.

Finally, the choice in favor of internal insulation is often made taking into account financial capabilities. External thermal insulation will cost much more, which has to be taken into account.

Why is there a problem?

The main risk when insulating a wall internally is due to the accumulation of moisture in it, caused by the mutual dependence of humidity and temperature conditions. The critical situation is caused by the “ dew point ”, i.e. temperature at which condensation forms from water vapor.

The problem arises because the internal insulation does not protect the wall itself from external cooling. The cold calmly passes into the material. At this time, fumes from human activity (hot water, kitchen, even just human breath) are directed into it from the side of the room.

These flows meet and at a certain point, where the desired temperature is reached (10.5-11 degrees), the active process of condensation begins. The “dew point” can be located at any depth in the thickness of the wall, which depends on many factors, including. on the temperature outside and inside the apartment, humidity, thermal conductivity of materials.

Condensation accumulates inside the wall or under thermal insulation, which already causes gradual destruction of the material, rotting, corrosion, and mold. In winter, this moisture freezes and expands, causing concrete or brick to crack. Thus, when installing internal insulation, measures must be taken to prevent moisture accumulation.

Pros and cons of internal insulation

Insulating a living space from the inside has its advantages:

• the ability to carry out work on your own, in any weather and at any time of the year;
• simultaneous insulation of not only the walls, but also the floor, and, if necessary, the ceiling;
• the formation of additional noise insulation and the possibility of masking communications;
• exclusion of high-rise works when the apartment is located in a multi-storey building;
• reduction in insulation costs.

The main difficulties and risks are associated with dampening the walls. However, in addition to this problem, some other disadvantages of internal insulation can be identified:

• loss of usable area due to the thickness of the insulation and subsequent plaster;
• the need to completely empty the premises of furniture and additional structures, as well as subsequent, thorough renovation of the entire apartment;
• the need to maintain temperature and humidity conditions in the room.

In addition to these disadvantages, it is necessary to take into account the increased requirements for insulation. The material is selected taking into account subsequent finishing and should allow the formation of a flat and smooth surface that is not subject to deformation for a long time. The most important thing is that it must be absolutely harmless to humans.

Advantages and disadvantages

Isolon insulation has many advantages, which makes it so popular:

• safe, does not have harmful effects on human health;
• due to low water absorption and vapor permeability, the insulation can be used without a waterproofing layer;
• elastic, therefore easy to install in difficult places. At the same time, it is elastic, so it easily returns to its original shape after dismantling and can be reused;
• precipitation and ultraviolet radiation are not harmful to isolon, therefore it is suitable for outdoor work;
• Izolon is one of the best insulation materials for walls. Example: 10 mm of insulation = 15 cm of brickwork, 20 mm of mineral wool or 5 cm of wood. Heating costs are reduced by almost three times;
• does not put a load on the structures being processed, as it weighs little;
• fireproof;
• service life reaches 80 years;
• During manufacturing, the material is not only covered with foil or metallized film, but also embossed and painted;
• Isolon is easy to use. It is easy to cut and attach to a surface, allowing for a self-adhesive base. A stapler, small nails, self-tapping screws or silicone glue can also be used for fixation;
• waste raw materials are reused;
• aggressive chemicals and biological destroyers do not affect the material;
• wide choice in terms of sizes, density, thickness.

There are isolona and disadvantages, but there are far fewer of them:

• relatively high price;
• the thin aluminum layer is easy to damage, so you should work with the material carefully. The same applies to its transportation;
• Isolon is not plastered, not covered with wallpaper and other finishing materials that can “load” it, which can lead to breakage of the insulation.

Note! For any work with the material, for example, if you need to insulate the floor in a wooden house using isolon, you will need at least basic skills in construction, otherwise there is a chance of damaging it. Damaged insulation will no longer be 100% effective.

Areas of operation

The versatility of the characteristics determines the use of the material in many areas:

• underlay – after insulating the subfloor with Izolon, you can lay carpet or laminate in a wooden house;
• protection of communication systems - climate and refrigeration units, gas and water supply lines, as well as ventilation;
• thermal insulation of any surfaces - subfloor, walls, roof, ceilings or basement;
• insulation of outbuildings (bathhouse, sauna) and utility rooms.

The insulator is also used in commercial construction.

Features of loggia insulation

Insulating a loggia with foil Isolon
To insulate a balcony or loggia you will need rolled Izolon, as well as a drill, a screwdriver, 2x4 cm and 5x4 cm bars, a stationery knife, and a furniture stapler. Using the material it is easy to create a kind of cocoon that retains heat:

1. Attach the slats vertically to the walls in 90 cm increments.
2. Form layer-by-layer thermal insulation - put foil Isolon 5 mm thick at the bottom, then foam plastic, then again foil Izolon 3 mm thick.
3. Secure the insulation with a stapler. One edge is fixed with staples, the rest is stretched to the rail and nailed with staples.
4. Seal the joints with metal tape or masking tape.
5. Treat wide gaps with polyurethane foam to eliminate “cold bridges.”

The loggia is insulated with Izolon with a foil layer on the inside.

Creation of wall thermal insulation

Izolon under the counter-lattice
Foil insulation is best suited for walls - the shiny surface of Izolon will direct thermal energy back into the room. When sticking to a polyethylene base, good sound, moisture and vapor insulation can be achieved. The work is performed as follows:

1. Installation of wooden slats 2x4 cm with a gap of up to 1 m.
2. Laying mineral wool into the frame by surprise.
3. Attaching foil-isolon to the beams using a stapler - the shiny layer is directed into the room.
4. Lay out the rolls so that all the joints match.
5. Sealing the cracks with metal tape.
6. Padding over the thermal insulation of the counter-lattice.
7. Installation of decorative finishing.

The distance from the foil to the finishing material is from 15 mm.

Thermal insulation of floor covering

To properly insulate the floor, you will need to additionally use mineral wool, polystyrene foam and expanded polystyrene. It is allowed to work on standard surfaces or to organize a substrate for heated floors. Experts provide a step-by-step algorithm of actions that must be followed:

1. Preparation. The old covering is dismantled and garbage is removed from the room.
2. Inspection of the lower structure. The peeled and cracked screed is removed and a new one is installed. All cracks are closed with mounting foam or cement-sand mortar.
3. Making a subfloor. Boards are attached to the surface in increments of up to 1 m, and chipboard or plywood is fixed to the joists. 5x4 cm beams are attached on top of the materials.
4. Installation of waterproofing. The surface is first coated with a primer and then lined with a waterproof film. Its edges protrude beyond the walls by 10-15 cm and are fixed with a stapler. The film is overlapped by 10-15 cm, all connecting lines are taped with metal tape.
5. Laying Isolon. It is allowed to use material 4-10 cm thick. Before installation, the insulation is cut into the required sections. Laying is done on top of the waterproofing coating, the joints are taped with metal tape.
6. Lag fastening. The extreme ones are located near the walls, the intermediate ones - in increments of 50-69 cm. They are fixed with self-tapping screws.
7. Installation of the second layer of thermal insulation. The auxiliary material is adjusted to the size of the cells and laid out without gaps. The cracks are closed with polyurethane foam. A polyethylene waterproofing film is placed on top of the mineral wool or polystyrene foam, which is secured with staples.
8. Laying the final coating.

For finishing flooring, you need a backing made of sheet plywood or boards 3 cm thick.

Material composition

Izolon is based on foamed polyethylene, having a thickness of 2 to 100 millimeters. At the same time, isolated air cells make this material an extremely weak conductor of heat, which makes it possible to insulate the room even at this expense. With sufficient thickness, of course. The foam base is covered on top with aluminum foil, which can be located on one or both sides of the material.

The material can also be used when insulating an external wall from the outside, located between the wall structure itself and the external decoration in the case of using curtain panels. In this case, the heat from the wall in the form of the same infrared radiation does not escape into the external environment. The proportion of reflected heat is very high, approaching 98 percent.

Specifications

• Material density - 19-200 kilograms per cubic meter;
• Sound absorption – up to 68 percent;
• Operating temperature from -80 to +80 degrees Celsius;
• Water absorption – up to 1 percent.

The last parameter means the material’s high resistance to humid air and water, which greatly expands its scope of application. This area, by the way, is really very wide: insulation and soundproofing of walls in apartments and private houses, floors (including self-leveling ones), interfloor ceilings, balcony structures, as well as non-residential premises. The material exhibits its properties well when insulating wet rooms with large temperature differences, such as baths. Finally, the material is used for pipe insulation, the production of workwear, as well as the manufacture of climate control and refrigeration equipment, but we will not touch on this.

Types and characteristics of thermal insulation Izolon

Foamed polyethylene Izolon with and without foil.

Izolon is a brand that produces polymer materials for insulation, noise and sound insulation with a closed-cell structure. Product line:

• Isolon 100 – non-crosslinked polyethylene foam;
• Isolon 300 – chemically cross-linked polyethylene foam;
• Isolon 500 – physically cross-linked polyolefin foam;
• adhesive tapes;
• reflective insulation - foil foamed polyethylene or metallized lavsan film.

The scope of application of the material is very wide: from civil engineering to manufacturing. This is facilitated by high performance. Isolon insulation, characteristics:

• density from 25 to 100 kg/m. cube;
• thermal conductivity – 0.037 W/m*C;
• does not allow steam and water to pass through;
• foil materials absorb 97% of IR radiation.

Some items can withstand heating up to 100 degrees without changing their physical and chemical properties. The service life declared by the manufacturer is at least 30 years. All types of polyethylene foam absorb sound and vibration waves well.

The choice of insulation for a ventilation facade depends only on the material from which the walls are built. For wood, materials that allow steam to pass through are used; for concrete, anything is suitable.

You will find information about insulating hives with foam plastic here.

Choice of insulation

If you decide to insulate your home yourself, you will have to make several decisions:

• Which structures require insulation?
• The better to insulate each of them.
• Can you handle this yourself?
• How much money are you willing to spend on this?

Saving wisely is not a shame. Therefore, we recommend turning your attention to the new generation of insulation - foil Izolon. Due to its high reflectivity and low emissivity, Izolon will allow you to get the maximum effect from the thermal insulation of buildings.

By insulating with Izolon, you save not only money by reducing the thickness of the insulation, but also living space. This is important if you are the “lucky” owner of a small apartment with low ceilings and can only be insulated from the inside. The cost of Izolon, in comparison with traditional insulation, is an ideal combination of price and quality.

For your information! Do not forget that foil Izolon has a very low coefficient of vapor permeability and water absorption. That is why it does not require the use of additional vapor-hydroprotective films to perform thermal insulation functions.

Answers from experts

.Moment. Apply in thin strips and glue

double sided tape is good

Nothing but a stapler. It will fall off. Tested many times. And food won't work. Look for foil for baths and saunas, preferably on kraft paper, so you can glue it with glue. Do not stick clean foil.

and why? If for thermal insulation - foam is better, for sound insulation it is better than mineral wool

not glue, but pin. With slats, you put the isolon on it, lay the slats evenly on it, drill holes, and fasten it. And so every 50 cm. Well, or vice versa - first the slats have a “lattice” of insulation on them. Is it really so difficult to figure it out? Why is it necessary to “glue”? It is pointless to glue anything other than stone or concrete to concrete. Otvalitsa. Or it condenses and leaves.

Special opinion, by the way, is right - a lattice made of slats with mineral wool and covered with plasterboard or plywood on top. Much better.

There is also a self-adhesive one - prime the concrete with any interior primer, let it dry for 12-24 hours and stick it on - and if it is not foil-coated, then you need to buy a foil-coated one - if not, then glue for linoleum type 88 I don’t know what it’s called, but the effect is one thin layer on one and on the other surface and glue

You need to know the strength of the concrete slab. try turning to professionals who work with them slav-beton /index.php?id=2 I’m sure they will give you advice on how to do this, or they will do your work for you. Good luck to you

How to choose the right material

Insulation of a wooden floor can be carried out using a variety of materials, which are also often used for insulating walls and roofs.

Such materials are considered:

• Mineral wool of different types (glass, stone, slag);
• Ecowool, polyurethane foam insulation;
• Polystyrene, penofol, isolon.

Materials known since ancient times can also be used: sawdust, polystyrene foam or expanded clay. You should choose floor insulation based on humidity, the purpose of the room, as well as personal tastes and financial capabilities. In a wooden house, it is additionally worth noting the possibility of waterproofing and resistance to insects.

Penofol and floor

It is necessary to leave a ventilated gap.

Thermal insulation of the floor in a wooden house. Floor insulation with penofol in a wooden house is carried out along logs. In this case, material types A and B can be used. The installation method depends on the type of thermal insulation chosen. We have already written about the comprehensive insulation of a wooden house according to modern technology.

Method using type A insulation. Work progress:

• surface preparation;
• choice of timber;
• organization of vapor barrier;
• laying the lower tier of logs;
• installation of the main insulation;
• laying penofol;
• second tier of logs;
• floor finishing.

The previous coating is completely removed down to the foundation. The surface is cleaned of debris and dust. To do this, it is advisable to use an industrial vacuum cleaner.

Penofol, as an independent thermal insulation material, cannot protect a building from heat loss. That is why it is used in combination with the main insulation, for example, polystyrene foam, mineral wool.

The joints are taped with special tape.

A stapler or construction staples are suitable for fixation if the balcony is insulated with penofol.

The joists are placed on top of the reflective insulation.

Experts tell you how to insulate a floor with penofol correctly on a concrete base. All work is carried out in several stages:

• rough floor screed;
• installation of penofol;
• installation of a metal frame;
• organization of the second layer of penofol;
• floor finishing.

If you are insulating unheated rooms or buildings that are used only in the warm season, one layer of penofol is sufficient.

Buleryan long-burning metal stoves were developed by lumberjacks in Canada.

The complex design of the Stropuva boiler does not allow you to make it yourself. Confirmation here.

Scope of application

• Unique technical characteristics have become the reason for the use of isolon not only in construction, but also in the manufacture of industrial and refrigeration equipment.
• It is widely used in the oil and medical fields, and is also suitable for solving plumbing problems.
• The production of vests, sports equipment, and packaging materials is also not complete without foil-coated isolon.
• In medicine, it is used in the production and packaging of special equipment and in the manufacture of orthopedic shoes.
• The engineering industry uses the material for automotive thermal insulation, as well as sound insulation of car interiors.

• Thus, the material is suitable for industrial and domestic use. It is noteworthy that its installation does not require professional skills or special tools. If necessary, the material can be easily cut with a knife. And the affordable price makes it possible for people with different financial capabilities to purchase it.
• The cost-effectiveness of consumption is also the reason for the widespread use of isolon on foil in everyday life. The user can cut the material as conveniently and economically as possible, and use small pieces of material for thermal insulation of small areas, joints and gaps.

If we talk about the construction industry, then this thermal insulation material is optimal for finishing balconies, roofs, external and internal roof walls. It is suitable for any surface, including for insulating a wooden house, since it ensures vapor permeability of the walls, which prevents wood from rotting.

• When finishing concrete walls, as well as surfaces made of building blocks, insulation allows not only to reduce heat loss, but also to ensure sound insulation of the room.
• Folgoizolon is used as floor insulation: it can be placed under a heated floor system, used in a dry screed or as a backing for floor coverings.

• It will be successful to use the material for thermal insulation of the ceiling. Possessing excellent waterproof and vapor barrier properties, the material does not require additional hydro- and vapor barrier layers.
• Foil-coated isolon is characterized by elasticity and the ability to take a given shape, so it is also suitable for insulating chimneys, pipelines, structures of complex configurations and non-standard shapes.

Technology for attaching isolon to the wall and material variations

The modern construction market is replete with all sorts of new products, often universal materials with a wide range of applications. We will talk about one of these materials today. This miracle of engineering called “izolon” ​​is widely used in construction as a heat and sound insulating material. Later we will describe all its capabilities in more detail. First, let’s concentrate on the main value – insulation of walls and floors. Attaching an isolon to a wall is a very simple process, but to the floor, in general, is as easy as shelling pears. The principle of fastening is similar to other soft-type insulation - they are attached to the wall using lathing, which also serves as a frame for future wall decoration, for example, plastic panels.

There are technologies for using isolon both indoors and outdoors. The second option is more practical (cold air is cut off, the walls do not freeze, and the heat from inside the house does not escape anywhere), but it is also more financially expensive, since the walls are insulated with insulation from the outside mainly under the siding. How to insulate - from the inside or outside - is up to you, but we will try to tell you in more detail about mzolon itself, the range of its applications, technical characteristics and other interesting facts.

Flaws

• Izolon has a relatively high cost, so for large volumes of work this can become a problem;
• Despite its flexibility, the aluminum layer is very fragile and can be damaged by external influences during storage, transportation or installation. If there is damage, a cold bridge is formed, which, with a relatively small thickness of the material, becomes very noticeable;
• Not every finish is suitable for isolon. The material can be covered with a protective film or painted, but cannot be used as a basis for wallpapering and plastering. The classic application scheme involves fastening the material for subsequent finishing with suspended structures, such as drywall or the same lining.

Nikifor Agafonov from Nizhny Novgorod is interested in:

I set out to insulate a private house in order to save energy resources. I decided to use modern technologies, but a dilemma arose: is penofol used as a vapor barrier and insulation at the same time, or should two layers of different materials be laid?

Our expert's answer:

Among modern insulation materials, penofol occupies one of the leading positions in popularity. This is due to the many advantages that the material in question has.

Harmlessness and environmental friendliness: the main components of penofol - polyethylene and foil - are widely used in the food industry and do not pose any danger to human health.

Lightness combined with strength - these qualities allow any type of transportation after rolling the foam foam into a roll.

Moisture resistance – absolute exclusion of moisture absorption and transmission.

Compliance with sanitary and epidemiological requirements - the product is certified, as evidenced by the relevant conclusions.

The presence of soundproofing properties.

Another advantage of the material is its availability - prices do not exceed, and sometimes compare favorably with, the cost of other well-known insulation materials (mineral wool, expanded polystyrene, etc.).

Due to its moisture resistance, the material is universal. In addition to its main task - insulation, it provides complete vapor barrier, since it has a high density and does not allow water to pass through in all its states of aggregation, including steam.

However, there are some nuances that can sometimes radically affect the decision to use penofol as insulation.

The material is too soft - it excludes the possibility of applying wallpaper or plaster on top, which will become a significant problem if insulation is carried out inside the building, since the aesthetic design of the wall is impossible

If you use penofol for outdoor use, it plays the role of an additional layer. Foam plastic is best used as the main insulation material, while penofol will reflect thermal energy and protect the walls from moisture.

Sequence of work during insulation

When working with isolon, you must adhere to the basic rules of installation and operation, which will allow the insulation to last longer, performing its duties efficiently.

Insulation of ceiling and floor with Izolon

This material has a small thickness, therefore, in order to obtain a high-quality thermal insulation cake, it is often combined with other insulation materials, for example, mineral wool.

The ceiling insulation method consists of the following steps:

1. Mineral wool is laid between the ceiling joists.
2. Isolon is attached stretched along the joists.
3. They stuff the counter-lattice.
4. Apply the finishing touches.

Isolon can serve as a sound insulator, for which it is placed directly under the finish. In this case, the material is attached end-to-end to the working surface using a construction stapler.

Note! If possible, it is better to leave a gap between the isolon and the finish necessary for the evaporation of moisture.

When insulating the floor with isolon from the inside, the work order looks like this:

1. Dismantling the old coating. If insulation is carried out in an old house, then first of all it is necessary to dismantle the existing floor covering.
2. Preparing the base. At this stage, the underlying structures are restored: the cracks are sealed, a new screed is poured.
3. Installation of floor waterproofing. The base is coated with a primer. After it has dried, the surface is covered with plastic film or a waterproofing membrane. Coating waterproofing can also be used.
4. Laying a thermal insulation layer. Sheet or roll insulation is adjusted in size so that it covers the entire surface. The joints are sealed with foil tape - there should be no gaps at the bottom, as they significantly worsen the thermal insulation properties.
5. Waterproofing material is laid on top of the isolon and a fine finish is provided.

Note! If necessary, double-layer insulation is installed.

Wall insulation with Izolon

As a rule, such work is carried out using additional insulation - mineral wool.

Order:

1. Wooden blocks for the future counter-lattice are attached to the wall.
2. Mineral wool is laid between the bars.
3. Foil-coated isolon is nailed on top of the bars. Its shiny side should be directed towards the room.
4. The rolls are laid end to end. Existing cracks are covered with aluminum tape.
5. The counter-lattice is nailed.
6. The trim is attached.

Additional Information! A gap of at least 15 mm should be left between the finishing material and the foil.

Step-by-step instructions for insulating floors with isolon

• We will assume that you have already gotten rid of the old rough finish and have approached the stage of preparing the foundation. First of all, it is necessary to repair all cracks and level the surface. In case of large differences in heights, it will be necessary to fill the screed, which will provide a smooth surface suitable for further finishing;
• The floor surface is primed, and after the primer has dried, polyethylene or a waterproofing film is laid on it. In this case, the latter must be placed on the wall to a height of 10-15 centimeters. As an alternative, you can use bitumen mastic, which is laid on a previously cleaned floor in two layers;
• Isolon is installed. As with walls, you should try to fill the entire floor space, avoiding even small gaps. The joints are taped with aluminum-containing masking tape.

Important! If work is carried out with isolon covered with foil on only one side, it is necessary to lay it with this layer inside the room, since the task is to retain heat inside, preventing IR rays from escaping into the walls or ceilings.

At the final stage, the joists are installed and the floor is finished. Sometimes, to achieve maximum insulation, roll insulation is placed in the space between the joists, and a second layer of isolon is mounted on top. Boards or sheet materials are laid on top, finished on top with linoleum, laminate or other methods.

Sequence of work during insulation

First of all, you need to decide on the thickness of the material, which depends on the availability of free space and climatic conditions. In cold regions, the insulating capabilities of isolon may not be enough, and it is better to use thicker layers of traditional insulation for this.

The leaves must be laid end-to-end, trying to avoid the appearance of gaps. To prevent this when finishing complex surfaces, you should carefully measure all the parameters and cut off the fragments with a high-quality sharp knife. In this case, the joints between the sheets are closed with aluminum tape, which also ensures the reflection of infrared rays.

In this case, empty space should be left between the isolon and further finishing, since otherwise condensation will collect on the material, which has mediocre vapor permeability.

Important! Do not place this foil material in close proximity to electrical wiring, as aluminum conducts electricity.

As for fasteners, many models of such insulation have a self-adhesive base, which allows you to radically simplify the process. If this element is not there, then the ideal solution would be to use acrylic-based adhesives or those marked No. 888.

Best answers

Try to stick it with drool...

You'd be better off insulating it with polystyrene foam from the outside. and the floor can be insulated. You talk to those who do this.

I think you need to consult a construction store at the store or try installation

First, prime it several times with bentonite, and then glue, but it’s better with a heat-insulating layer, even PVA, but there are some that are sold as self-adhesive on a heat-insulating backing.

think about it, maybe galvanized iron, or better yet stainless steel, because foil is weak

oh, if the sticker is crooked, get a magnifying glass, with a focus like in ancient Greece they burned the fleet)

I use Termoizol - foil on foam, it’s easy to work with: I insulate steel baths - they turn out no worse than cast iron ones, they are warm. And food grade can be glued onto cardboard with slots for hooks for easy insertion.

Buy penofol, they are sold in different thicknesses. It can be self-adhesive, but if not, try double-sided tape!

If the foil is glued to the glass with egg yolk, then it will definitely stick to the concrete

Recommendations for use

When choosing foil insulation, you should decide on its thickness, which depends on the place to be insulated. To insulate the floor, a thickness of 0.2-0.4 cm is sufficient. For insulation of interfloor ceilings, rolls or layers from 1 to 3 cm are used. If isolon is used as a sound insulator, a thickness of 0.4-1 cm is sufficient.

Styling Tips:

• foil-coated isolon should not come into contact with electrical wiring. Foil is a metal that is an electrical conductor;
• When insulating a balcony, you should remember that isolon only retains heat, but does not generate it. Accordingly, insulation is half the task; you will also have to take care of the availability of heat sources;
• the air gap will prevent condensation accumulation;
• the material is laid end-to-end, and the joints themselves are covered with aluminum tape.

If you do all the work correctly, taking into account all the requirements, then when insulating the balcony you will have to sacrifice a small internal area. It will be occupied by mineral wool.

Foil-coated isolon is a material used for moisture, noise and heat insulation in both residential and industrial premises. Despite its small thickness, it effectively performs its duties. But in order for the insulation to last longer, it is necessary to adhere to the installation rules.

Installation features

The insulation reflects heat from the radiator into the room.
Instructions from specialists apply to any surface for insulation. When laying insulation, the following rules should be observed:

• Internal insulation involves fastening Izolon between the finishing and the wall - the thermal efficiency of the structure increases.
• The highest percentage of heat retention is provided by material with double-sided foil.
• Two layers are laid on the concrete. The first is on the covering, the second is on the joists.
• It is better to insulate a loggia or balcony with single-layer foil Isolon according to the “construction pie” principle.
• In the apartment, you can place the material behind the radiators - this eliminates the need to dismantle the walls.
• The foil layer should not come into contact with the wiring.
• To prevent the formation of condensation, an air gap is required between the insulation and the rest of the structure.

The material is laid only joint to joint and must be glued with aluminum adhesive tape.

Thanks to closed cells of rolled insulation, 70% more heat is retained in the room. When performing thermal insulation, additional load on the structure is eliminated - a thin layer of material is highly energy efficient. It can be laid on any surface - walls, ceiling, floor or laid out on the balcony.

Cottage and House - Vapor permeability of materials on the Perm scale

Vapor permeability of materials on the Perm scale

The vapor permeability of building materials in the USA is measured in comparative units Perm (from the term permeability - permeability).

The article was written based on materials from the brochure “Vapor Permeability of Common Building Materials” EEM-00259, University of Alaska, Fairbanks, 2011.

In cold and humid climates, the best vapor barrier is polyethylene film with a thickness of 150 microns or more. In wet rooms (bathrooms), the thickness of the film vapor barrier must be at least 250 microns.

Construction materials are divided into:

Vapor-tight (vapor permeability less than 1 perm): Polyethylene, foil materials up to 0.1 perm Roofing felt 0.4 perm Oil paint, vinyl wallpaper, EPS - up to 1 perm

Conditionally vapor-permeable (vapor permeability 1-10 perm): OSB - 1-2 perm Plywood, foam plastic, glassine, latex paints from 1 to 10 perm Kraft bitumen paper (glassine) 1.5 perm

Vapor permeable (vapor permeability more than 10 perm): Gyprok, ecowool (cellulose insulation), glass wool, thin glassine - more than 10 perm

Vapor barriers according to the International Building Code 2009 (IRC 2009) are divided into three classes: Class I: vapor permeability less than 0.1 perm. II class 0.1 -1 perm. III class 1-10 perm.

Materials such as OSB-3 are “smart vapor barriers.” Thus, at normal humidity, the vapor permeability of OSB is about 2 perm, and when humidity increases to 85%, the vapor permeability of OSB increases to 12 perm.

Rating of vapor permeability of building materials in perm (perm).

Attention! For every doubling of the thickness of a layer of building material, vapor permeability decreases by 50%.

How to insulate with penofol

Important. Unlike various thin films, the installation of penofol sheets is carried out not overlapping, but end-to-end. In this case, the foil side should be facing inside the room, and the joints should be carefully taped with aluminum tape.

Note. Perforated penofol is used as insulation for the walls of a wooden house in cases where it is necessary to ensure vapor permeability of the structure.
