Polynor or ppu which is better. Overview of sprayed polyurethane thermal insulation polynor

Polynor is a polyurethane foam based insulation developed jointly by construction companies. Means "Polynor" consumer reviews received good as a modern material, ideal for heat and sound insulation. In addition, the scope of its application is wide, which opens up great opportunities for insulation work.

Consumer properties

Like any insulation material, Polynor has a number of advantages:

1. It has excellent heat retention. These indicators for insulation are higher compared to polystyrene foam and mineral wool.
2. Non-toxic. Consumer reviews about the Polynor product are not bad, because it is not poisonous and protective equipment is not required when using it.
3. Ease of use. When using POLYNOR, a heat-insulating layer is created, for which a frame is not needed as a fastener. Also, no tools or auxiliary materials are required.
4. Excellent grip. The composition quickly adheres to any surface - brick, wood, plastic, stone, concrete, which significantly expands the scope of its application.

Polynor insulation is very popular due to the fact that it is applied by spraying. This affects the better adhesion of different surfaces, even if they are not very smooth. Very often, this insulation is used to finish hard-to-reach places, for example, where pipes or cables are laid.

Where is it applied?

One-component POLYNOR is widely used for heat and sound insulation of the following elements:

• facades;
• loggias;
• terraces and verandas;
• attics and mansards;
• cellars;
• residential premises - apartments, houses;
• industrial premises;
• pipeline systems, engineering communications;
• thermos vans.

Application features

Consumer reviews are quite common about Polynor insulation, which is explained by its ease of use. The principle of working with it is as follows:

1. Preparation of the work surface for further finishing. To do this, you need to rid it of stains, dirt, and moisturize it well.
2. A cylinder with insulation should be in a room at a temperature not lower than 18 degrees.
3. Before work, you need to put a special nozzle on the cylinder, which comes with the kit, until it clicks.
4. Remove the cover from the cross and screw the gun onto the base. By the way, it is not included in the package. During this procedure, the balloon must be vertical.
5. The balloon is thoroughly shaken.
6. The sprayed insulation is easily applied by dosing by pressing the trigger of the gun. You need to spray a layer no more than 5 cm thick.

Due to the ease of use, Polynor insulation is very popular in everyday life. The instructions for its use are simple, so even a novice user can handle it. As already mentioned, the material can only be applied to a cleaned surface. Moreover, if work is carried out with galvanized profiled sheet metal, you first need to wipe its surface, remove all stains and an oil film from it, which is always present on the metal due to the peculiarities of the technological process. The heating of the aerosol is necessary so that the mass in the cylinder does not freeze and is sprayed evenly.

Using the nozzle

"Polynor" - sprayed insulation, which is applied with a special plastic spray nozzle. It is attached to the tip of a conventional mounting gun, and for this you need to remove the nozzle from the spray gun, press it against the tip of the gun, then insert it into the spray nozzle until it clicks. The main thing is not to allow too much load, as this can lead to cracking of the nozzle body. It is impossible to use a nozzle for work with normal polyurethane foam.

After the insulation has been applied, it can be treated with water with a conventional garden sprayer - this will accelerate the polymerization and better foaming of the newly created thermal insulation layer.

We follow the rules

As already mentioned, consumer reviews are often found about the Polynor tool. With the simplicity of its use, you need to approach this process as responsibly as possible. Firstly, during spraying, a mass that has not yet hardened in the form of foam can irritate the skin, eyes, and respiratory organs. To avoid this, you need to use traditional safety equipment in the form of gloves, goggles. And if the decoration is carried out from the inside and the room is difficult to ventilate, you need a respirator during work. If, nevertheless, the foam gets into the eyes or on the skin, you need to treat them with warm water.

The reviews about Polynor insulation are good, but when using it, you should remember that the cylinder contains gas, which is a foaming agent. It is heavier than air and is flammable. Therefore, spraying should ideally be carried out in well-ventilated areas. Important: when using Polynor indoors, you can not smoke and / or work near open flames.

"Polynor" for the floor

This spray-on insulation is ideal for indoor comfort. Thanks to competent thermal insulation of floors, you can make the room warmer, while saving on additional heating. Moreover, you can use Polynor on your own - this does not require special knowledge. Features of its application are that it is sprayed onto an already prepared surface and easily adheres to any material - from brick to wood and plastic.

As a heater, "Polynor" received positive reviews:

1. Supported comfortable temperature in room.
2. The low degree of water absorption makes it possible not to install a vapor barrier layer.
3. The material contributes to good vapor, hydro and sound insulation.

Cellar insulation: cheap and high quality

When decorating a house or apartment, we are looking for quality materials, which at the same time would differ in economy. One of the materials that meet these requirements is the Polynor insulation. The price starts from 400 rubles per spray bottle. That is why it is often used when it is necessary to insulate the cellar. When carrying out these works, the dimensions of the foundation and the height of the base should be taken into account. Most often, foam plastic is used to insulate the basement, but it is not easy to work with it, so many people prefer the more economical option - Polynor. TO distinctive features its applications include:

1. No need to build a frame, since the insulation is sprayed directly onto the surface. The material fills all the microcracks, which ensures reliable thermal insulation.
2. "Polynor" has a high thermal conductivity, so you can apply it in a small thickness.
3. Simple installation allows you to perform insulation with your own hands without the use of special tools.
4. "Polynor" does not absorb moisture, therefore it serves as an excellent waterproofing layer.
5. After applying the insulation layer, it can be further processed - painted or plastered.

How to soundproof a ceiling?

Noise in the apartment no longer surprises anyone, but it can be minimized with the help of Polynor construction sprayed insulation. Consumer reviews about it are enthusiastic, and not only the affordable price and ease of use are noted, but also high performance soundproofing. What is the benefit of using this particular material? Firstly, it needs to be applied in a very small layer, so your ceilings will practically not lose in height. Secondly, silence and tranquility will finally reign in your home, because in terms of the level of noise-absorbing characteristics, as well as due to its high density and elasticity, the material perfectly absorbs all noise.

"Polynor" is a heater, the price of which cannot but rejoice. When installing it, again, the construction of a frame is not required, since, when it hardens, it forms it itself. And after the foam has hardened, you can treat the surface with plaster or paint. Another important point- to mount this building insulation, now you do not need to call professionals - you can do the soundproofing yourself!

We insulate the roof

"Polynor" is a universal material through which you can perform whole line insulation work in the house. As for the arrangement of the roof, experts advise paying close attention to this process and not choosing too cheap materials. However, many modern builders prefer such material as "Polynor". Its price is affordable, but in terms of surface quality it is not inferior to expensive analogues. In order for the roof insulation to be done correctly, you need to follow the order of work.

Stages of roof insulation

As you know, any roof consists of several materials:

1. Directly roofing material in the form of roofing material, metal.
2. Wooden crate.
3. Vapor barriers.
4. Waterproofing.

Most often, mineral wool or fiberglass is chosen as the quality, and this is understandable: they are distinguished by a breathable structure, have good vapor permeability, are resistant to fire and are ventilated. On the other hand, these materials can sag, respectively, cold bridges will form. Secondly, due to changes in temperature and humidity, the insulation can collapse and lose all its protective properties.

Warming with modern material

Polynor is a heater, the price and characteristics of which cannot but rejoice. Firstly, when using it, you do not need to call for the help of experienced specialists, since spraying can be done independently. Secondly, this insulation fully meets the requirements of vapor permeability and at the same time serves reliable protection from moisture. Thirdly, when spraying "Polynor" joints are not formed and the insulated roof becomes single and solid. Accordingly, it will be provided with good waterproofing.

Warming of the house or bath

One of the most reliable and easy-to-use materials for insulation is Polynor. Its characteristic as a heater is always positive, which is due to many factors. The use of this material is expedient and beneficial because it is possible to make the process of insulation competent and efficient, which means that you can significantly save on heating costs. When insulating houses, baths and in general any residential buildings, much attention is paid to achieving the following goals:

• preventing drafts inside the premises,
• isolation various designs from exposure to cold air,
• protection of buildings from the negative impact of environmental factors.

All these requirements are met by "Polynor" - a modern insulation that is easy and convenient to work with. Unlike classic polyurethane foam, it is resistant to moisture, does not deform during operation, allows you to isolate structural elements. Before starting work, you should prepare the surface for them, and then arm yourself with a conventional household spray gun. At or country house it is necessary that polyurethane foam insulation be certain temperature. This will ensure fast and high-quality polymerization of the surface. Also, when using an aerosol, you should shake the can well so that the spray is carried out evenly and efficiently.

Compliance with the stages of applying insulation plays an important role. So, first, the first layer must be applied to the surface - its thickness should not be more than 0.5 cm. It is not worth increasing the insulation layer, because as it hardens, it will expand anyway. Once the first layer has hardened, the second layer can be applied. "Polynor" is a unique material, since it can be used to conveniently process the most hard-to-reach places, for example, the corners of apartments, houses. The final layer of insulation is applied to obtain a final thickness of approximately 5-6 cm. Many will say that POLINOR is the same mounting foam, but in fact the chemical composition of these materials is significantly different. Accordingly, the technical and operational properties of the material will be different. Due to plasticity, reliable adhesion of the material to the surface is ensured.

Where to buy "Polynor"? In any stores that offer building and finishing materials. Reviews about this Norwegian heater are mostly good, because it is easy to use and allows you to process hard-to-reach places. Of the minuses, users note a persistent smell that lasts for a long time, moreover, if a large surface area is processed, too much material will be required, which is not very profitable.

The modern market of building and finishing materials offers a huge amount of insulation materials that differ in characteristics and operational properties. Polynor polyurethane insulation is the most effective of modern materials, which is used for thermal insulation of the house.

Polynor thermal insulation is a novelty in the Russian construction market. It is a sprayed polyurethane foam, which has excellent sound and heat insulation characteristics, due to its composition, it consists of 90% air.

At the same time, it is extremely easy to mount, which puts it an order of magnitude higher than others. thermal insulation materials.

Unlike similar insulation materials, liquid insulation has the following advantages:

• efficiency;

The energy saving coefficient when insulating with Polynor is carried out is higher than that of such a popular mineral wool.

• profitability;

For fastening, it will not be necessary to build an additional frame or use hydro- and vapor barrier materials, and there is also no need for special devices and shipping costs to the repair site.

• ease of installation;

One person can spray the material. Its application does not require labor-intensive preparatory work, surface leveling, etc.

• minimum consumption;

The question of how much insulation is needed can be easily answered. One liter of liquid is enough to create a four-centimeter insulating layer on a surface of 1 sq.m.

At the same time, the cost of such a heater is noticeably lower than the same mineral wool, which will require many more additional materials (vapor barrier, waterproofing, crate, fasteners, etc.)

• excellent adhesion to any kind of materials;
• biostability and lack of condensate.

Along with a large number of advantages of Polynor insulation, it also has some disadvantages:

• the negative effect of sunlight on it;
• collapses under the constant influence of water;
• when applied, it needs a temperature from +15 to + 25 degrees;
• dangerous for the eyes and respiratory organs (requires the use of a respirator and goggles).

Scope of application

The description of the insulation presents us with a modern, almost universal material that has a fairly wide application as a finishing and insulation material, in particular:

• for facades for finishing;
• for foundations and attic spaces;
• for balconies;
• for warming the internal walls of the building, partitions in various buildings;
• to isolate communication systems;
• v vehicles with isothermal functions.

As you can see, the application is wide. And this is understandable, since the heat insulator has good performance properties, fits perfectly on any surface, is very flexible and is not subject to destruction, even if a crack appears on the surface. The material is non-toxic and perfectly absorbs sound and vibration waves.

Release form

Sprayed insulation has been known since 2013. It is a one-component self-increasing mixture with a closed cell structure.

In construction stores, this thermal insulation is sold in cylinders similar to conventional mounting foam under the pistol.

It is applied in the same way as building foam. According to reviews, one cylinder is enough for a 5 cm layer of insulation on an area of ​​​​one square meter. The manufacturer's instructions state that the service life, in the absence of negative factors affecting it, will be at least 35 years.

Mounting Features

Cylinders with insulation should be kept in a warm room until they are used. This important point, because negative temperatures can adversely affect the performance of the foam insulation.

The heat-insulating mixture can be applied both to a clean surface and to the crate, it all depends on the chosen method of finishing the room. It adheres well to almost any material. Spraying is easy, even by non-professional hands.

In addition to the walls and facades themselves, Polynor foam can easily insulate various communication pipes, well caissons and complex construction projects.

Before applying any insulation, including Polynor sprayed insulation, the surface is thoroughly cleaned of dirt and debris. If defects or surface damage are found, they should be repaired. A crack in the wall, for example, cannot affect the insulation in any way, but it may well spread under the insulation layer. Therefore, it is better to immediately repair it with glue and cement composition.

Then the insulated plane is thoroughly degreased. special formulations. This is necessary due to the fact that Polynor insulation does not adhere well to an oily surface.

Then spraying is carried out with an aerosol gun, to which a nozzle is attached to control the flow of material and the supply of foam.

A nozzle is installed on the barrel of the pistol, and then the pistol rod is screwed into the cylinder freed from the cover. The balloon is ready to go.

Foam insulation is applied in a layer about 5 centimeters thick. The feed is regulated by pressure on the trigger of the construction gun. The foam can needs to be shaken every few minutes of use.

Do not forget about the precautions when using this heater. Be sure to use a respirator and goggles, as uncured insulation can harm the human body.

The composition applied to the wall is distributed over the surface, filling small cracks and irregularities, forming a dense layer of foam, which hardens over time, creating a reliable insulating layer.

For several years of use, Polynor insulation has already managed to win admirers. Many professionals who have been using polyurethane foam for a long time have given their preference to the novelty. It is noted that it is extremely easy to install, fits perfectly on any surface and has good performance during operation. Thermal insulation passes quickly and at a high level.

It is also noted that the material is extremely toxic, so you should take precautions, protect yourself with special suits, gloves, respirators and goggles. If foam gets on the surface of the skin, it should be thoroughly washed and consult a doctor.

Also in consumer reviews it is noted that Polynor insulation is quite expensive in cost, but this factor should not be decisive when choosing a heater. The speed of application and excellent characteristics will allow you to save several times on heating the room in the future.

The material is highly toxic, so precautions should be taken

Professionals also often prefer this material. His light structure and ease of application can significantly reduce the time and cost of installation insulation.

Comparison of insulation Polynor with Penoizol

Experienced builders and finishers have already dubbed Polynor insulation a full-fledged replacement for liquid polyurethane foam. At the same time, the final price for surface insulation will be significantly lower than when using PPU. In addition, during the installation of PPU, it is necessary to use special equipment that needs to be transported, incurring additional monetary losses. Using a heater in cylinders, everything is much simpler.

Experienced builders and finishers have already dubbed foam insulation in Polynor cylinders a full-fledged replacement for liquid polyurethane foam.

Among the characteristics can be distinguished excellent vapor barrier. An analogue of polynor polyurethane foam, it passes steam worse and condenses moisture, unlike a heater in spray cans. This is especially important when insulating houses made of wood.

Both materials are non-combustible, this is their similarity, but Polynor has the properties to pass steam and remove moisture, while polyurethane foam shows the worst performance in these properties.

In addition, polyurethane foam is a rather bulky material that requires shipping costs and additional application equipment.

Summing up, it should be noted that the modern insulation material Polynor is an excellent means for insulating any surfaces, convenient, with good performance properties, which will last for many years, subject to certain measures to protect the heat-insulating layer.

Ease of installation and good expense The material, as well as the consumer reviews left about Polynor, win over not only people who decide to do the insulation with their own hands, but also experienced professionals who increasingly prefer this modern insulation.

When building a country house, thermal insulation work is indispensable. A good owner will always take measures to insulate the walls and roof. When choosing required material for this, one of the main questions that arises for the owner of the house is what kind of insulation mice or their relatives do not gnaw.

First of all, it concerns the insulation of the floor and walls. As you know, many of the thermal insulation materials serve as a cozy house for these animals. Rodents do not eat any of the existing heaters, but they gnaw them with particular pleasure, arranging nests and passages inside it, and if they appear thicker than such material, then it is almost impossible to evict them from there. Therefore, choosing a thermal insulation material, you need to carefully study all its characteristics so that you do not have to redo all the work done again.

Applied heaters and their properties

It should be noted that there are few obstacles for mice that they are not able to overcome - these small rodents penetrate through the narrowest cracks that form at the junctions of the walls of the house and concrete sills, and through almost imperceptible cracks in the facade cladding. If, having penetrated into the insulation, rodents feel comfortable in it, they cannot be smoked out of there, therefore, the material for thermal insulation must have such properties that are unacceptable for animals to exist in its thickness. There are several such materials, and they are quite affordable for any owner of a house under construction.

Expanded clay

It has long won recognition as a reliable thermal insulator, as it has many advantages. It perfectly not only warms the house, but also absorbs noise. It is completely non-flammable, and most importantly - rodents do not live in it.

Expanded clay is made from clay of special grades, which is cleaned, carefully rubbed and kneaded into a plastic solution. Then granules are formed from it and hardened in a certain temperature regime, at which swelling of the mass is achieved. When cooling, the insulation becomes light in weight and at the same time very durable, able to withstand significant mechanical stress.

Expanded clay can have different fractional sizes. So, it is produced in the form of sand, fine and medium-sized gravel, as well as large, up to 10 - 25 mm granules.

It is unlikely that rodents will choose at least some of their similar materials for nesting and living. If they can move through large fractions of the material, then mice, and even more so rats, will simply drown in a heater in the form of fine gravel and sand. Rodents simply cannot live in such material, since there is not enough air in its thickness and a large number of small particles that will clog the animal's airways. Mice or rats will also not be able to gnaw on expanded clay, since it is too tough for them, so they have nothing to do in a house where there is danger for them.

Expanded clay insulates basements, interfloor and attic floors, but you can use it for wall insulation.

• To do this, a kind of formwork is made near or inside the walls, having the desired thickness, into which expanded clay is poured. It tightly fills all spaces without tamping.

• For a rough base, a vapor barrier material is laid, which is fixed to the logs. Expanded clay is poured on it and again covered with a vapor barrier from above. Further, a finishing floor of boards or plywood is laid on the logs.

• In addition, fine expanded clay is used for the construction of a bulk floor using the "dry screed" technology, where it serves as a heater and sound insulator, and in addition - the basis for laying gypsum fiber panels. Arranging such a floor, expanded clay can be poured both on the ground and on the concrete surface.

Expanded clay of fine fraction - the main component of the "dry screed" of the floor

But first, waterproofing material is laid on any of them, if it is laid in separate sheets, they are glued together with special adhesive tape. The waterproofing is lifted onto the walls by 15 - 20 cm, and a damper tape is installed along the wall and only then expanded clay is poured.

Gypsum fiber boards laid on expanded clay backfill will create a flat and durable floor surface

On top of such an embankment, carefully leveled horizontally using a system of temporary beacons, gypsum fiber panels that create a hard surface. In such a warmed base of the floor, rodents will never start.

• Since the mice manage to penetrate the interfloor and attic floors, they are also filled with expanded clay chips.

Expanded clay prices

Expanded clay

Foam glass

Another material that mice and their relatives do not favor is foam glass. It is produced in slabs and in bulk.

Foam glass - mice will not like this material

The placer material has the same properties as the fine fraction expanded clay, and is used in the same way for walls, floors and ceilings.

Plates are mounted on the walls from the outside or inside, and also put on floors, on concrete mortar, bitumen, building glue, or on foam glass or expanded clay previously poured under them in a fine fraction.

Foam glass is a heat-insulating material that is made by melting and foaming glass. This process is possible due to the ability of glass to soften and boil at a temperature of 950 ÷ 1000 degrees.

When solidified, the material acquires high strength - this should reliably protect the house from the penetration of rodents. However, it must be remembered that the solution on which the plates are attached must be of high quality, and the seams between them must be airtight. Only in this case, the mice will not be able to enter the premises.

• Foam glass perfectly resists not only rodents, but also the appearance of fungal formations and the appearance of insect nests.
• The material is durable, not damaged by moisture and does not decompose from ultraviolet radiation, does not crumble and retains its thermal insulation qualities for many years.
• A very important advantage of foam glass is its environmental friendliness - under any conditions, the material does not emit any harmful fumes that adversely affect the health of residents.
• Foam glass can be processed with a hacksaw or a jigsaw, so it is very easy to work with it during the installation of thermal insulation.

Ecowool

To avoid settling rodents in the insulation, experts recommend using ecowool. It's relative new material, but it confidently occupies its niche among the frequently used effective thermal insulators.

Installation of ecowool occurs with the help of special equipment, which helps to distribute the material over the insulated area. After the initial setting, the applied layer is leveled with a special roller.

The question arises as to why rodents bypass ecowool, because it is soft and easily amenable to the teeth of mice and rats. The secret of the dislike of these animals for such a heater is that in its manufacture the manufacturer adds to a mixture of orthoboric acid, which causes suffocation and dehydration in rodents. It is possible that individual specimens will try to arrange a nest in ecowool, but they will not be able to stay in this insulation for a long time, and even more so - to breed, so the rodents quickly leave the seemingly cozy place to live.

Ecowool treated with orthoboric acid has antiseptic properties, and also releases moisture well when heated, thereby providing sufficiently high fire-fighting characteristics.

Ecowool is produced from cellulose, which is absolutely harmless to the human body, so insulation can be carried out not only outside the building, but also from the inside, distributing the material between the crate of timber installed on floors and walls.

Ecowool has low thermal conductivity and sound conductivity, therefore it retains heat well inside the premises and drowns out all the noise coming from the street, as well as from other rooms, if interior walls are finished with it.

Ecowool remains functional for many years, as it is not subject to rotting and decomposition.

foam concrete

Another insulation that rodents will definitely not like is this. And, the material is produced in two forms - in the form of blocks and a special solution.

• Walls are laid from ready-made blocks, or they are laid over ready-made brick or wooden walls.

• The solution is spread over the surface of the floor or filled with formwork, arranged, for example, from two rows of brickwork.

This material is composed of cement, water, sand, and a blowing agent. When solidified, it acquires rigidity and a pronounced porous structure. Mice will definitely not gnaw foam concrete, trying to make a nest in it, since such conditions are unacceptable for them.

The walls are insulated with foam concrete only from the outside of the building, or the mass is poured into the middle of the masonry during its construction. Indoors, it is rarely used for wall insulation, since it must be strictly observed technological process, and at the slightest deviation from it, condensate may appear in the walls, which means that the development of mold processes begins.

The floors may well be filled with foam concrete mortar. When completely solidified, it will become a reliable basis for decorative design surfaces. Floors filled with this material will receive excellent thermal and sound insulation.

If the walls of houses are taken out, then such structures are considered reliable, warm and durable, since the material does not absorb moisture, is not subject to cracking, which means that it will be inaccessible not only for rodents, but also for the appearance of colonies microorganisms or insects.

Foam concrete blocks are light in weight, so laying them is easy. They are environmentally friendly and do not pose any danger to the inhabitants of the house. They are easy to process - cut or drill holes if necessary. The material is absolutely non-flammable and does not rot.

And what about the usual heaters?

1. Penoizol is the same foam, only sprayed in liquid form on walls and floors using a special compressor. Many articles indicate that mice do not gnaw on this material due to its constituents, but, unfortunately, this is not true. Rodents do a great job on this material. Perhaps they will not arrange moves and nests in it, but they gnaw it with great pleasure.

The same can be said about extruded polystyrene foam - it is dense enough, and therefore mice or rats will not live in it, but they will not refuse to gnaw it.

Ordinary foam plastic will become not only a simulator for teeth, but also an excellent place for making nests and passages. Rodents freely pass through it, find cracks in the wall and enter the house.

2. All types of mineral wool are also tough for mice and rats, and it does not matter whether it is glass wool or stone. Any of them is suitable for rodents to settle in it for living.

Mice have already done a good job on this mineral wool insulation layer.

They do not eat this material, but skillfully crush it, arranging their houses, and if they have already chosen the insulation layer of a certain house, it will be very difficult to remove them. The trouble is that poison cannot be laid out for them, otherwise the rodent can say goodbye to life right in the nest, and then it will be very difficult to get rid of the putrid smell. Therefore, it is not recommended to insulate the lower part of the house with these materials.

In order for the house to be protected from rodents, its basement and basements must be insulated with hard or bulk materials, and the joint between the wall and the concrete tide must be very carefully sealed. It is extremely important that no cracks and cracks form in this place - even the smallest of them will be a good loophole for gray slickers. And yet - to private house was protected from mice, you must definitely get a good active cat that will intercept rodents on the way to the house.

But, choosing a heater, after all you need to follow the tips given above, which are based on the performance characteristics of the materials and on the experience of numerous owners of private houses.

In the modern market of finishing and construction products, there is a large selection of materials for insulation, which differ in properties and performance characteristics. One of them is Polynor, a heater that appeared not so long ago, but has already proven its effectiveness in thermal insulation of houses. This is a novelty on the Russian market, which is a sprayed polyurethane foam with excellent sound and heat insulation properties, which will be discussed in more detail in the article.

Polynor sprayed thermal insulation

Polynor refers to seamless insulation. Consists of a one-component, spray-applied polyurethane foam. Its functional task is thermal insulation of surfaces. The working tool for application is mounting gun on which there is a special plastic nozzle. The insulation itself in the form of a substance is located in a disposable can of a certain volume.

Specifications and scope

Sprayed polyurethane insulation called Polynor has the following performance parameters:

• water absorption - 2%;
• density - from 18 to 28 kg/m3;
• thermal conductivity - 0.023 - 0.025 W / mK;
• to which flammability group does it belong - G3;
• polymerization time at a temperature of +20 degrees Celsius - from 40 to 45 minutes;
• the time required for complete drying - 36 hours;
• recommended thickness - 25 - 60 mm;
• service life - no more than 35 years (it all depends on the conditions).

Polynor sprayed insulation is essentially universal, as it can be used both as finishing material. Areas of application:

• they process facades for finishing;
• foundations and attics;
• balconies;
• they are warmed internal walls, partitions;
• isolate communication systems;
• also finds application in transport with isothermal functions.

There are enough areas where Polynor is used, which allows its operational characteristics. The material is flexible, resistant to destruction and easily applied to almost any surface. In addition, after hardening, it is environmentally friendly and is able to effectively absorb sound and vibration.

Balloon volume

Polynor foam insulation is in the form of an aerosol and is supplied in 890 ml cans. Visually, this is a polymeric substance that has a pinkish tint. Sprayed with a special gun. Liquid polyurethane forms a dense foam that is applied to work surfaces.

Pros and cons

From positive qualities allocate:

• insulation in cylinders called Polynor, unlike other heat-insulating materials, does not require the arrangement of a frame (we are talking about films, reinforcing meshes, and the like);
• it is convenient for them to work, especially if a hard-to-reach area or a surface with complex geometry is processed;
• to spray thermal insulation, you will not need additional equipment and an electrical connection;
• suitable for processing brick, wood, metal, glass and other surfaces;
• in comparison with traditional heaters has increased thermal conductivity;
• increases the speed of work. To apply a layer of 1 m 2, it will take no more than two minutes;
• low consumption. One bottle of sprayed Polynor insulation, with a volume of 890 ml, is enough to cover the surface of 1 m 2 with a thickness of 5 cm;
• hardens the material within an hour, after which other coatings are applied on top of it, for example, paint or plaster;
• according to the manufacturer, the service life reaches 50 years;
• along with thermal insulation provides sound insulation;
• will not become a "home" for rodents who love to spoil insulating materials so much.

Polynor - insulation in the form of foam for wall insulation in cylinders. Along with the advantages, this new generation material also has a number of disadvantages:

• direct solar radiation adversely affects it;
• will not last long if it is often exposed to moisture;
• restrictions during spraying. Namely, the temperature of the cylinder should be in the range from +18 to +35 degrees Celsius;
• toxic during operation until dry. As a result, funding is required personal protection, i.e. masks, gloves and the like;
• using for the first time, it is difficult to apply a layer of perfectly even thickness;
• as recommended by the manufacturer, the maximum layer thickness should not exceed 6 cm;
• after application, it seals the surface, preventing it from "breathing";
• for work, you will need to purchase a construction gun equipped with a nozzle.

Helpful information! As for combustibility, Polynor is a self-extinguishing material, at least if it is not directly affected by open fire.

Application technology

Cylinders should be stored in a warm room, as sub-zero temperatures affect performance characteristics this heater. Depending on how it is implemented finishing, Polynor is applied both on a clean surface and on a crate. The application procedure is simple, which even a beginner can handle (although you won’t be able to guess the thickness).

Before applying Polynor, however, like other heaters, the working surface is carefully cleaned of dirt. If there are defects on the wall, they should be repaired. For example, a crack will not affect the properties of the insulation in any way, but this will not prevent it from spreading further. Therefore, it is better to eliminate all defects immediately.

The next stage is a thorough degreasing of the plane, for which special compounds are used. The fact is that the adhesion of Polynor with an oily surface will be poor. Further, inserting the canister into the gun, they begin to spray.

On average, the layer thickness is 5 cm. To adjust the pressure, the trigger of the pistol is pulled with one or another force.

Note! Shake the bottle every few minutes. Safety measures must be taken into account - in an unhardened form, the insulation is hazardous to health.

The composition, after being applied to the wall, fills all the recesses and cracks, after which it solidifies, thereby forming a reliable insulation.

Consumption per 1 m 2

As noted in the benefits, this insulation is quite economical. The consumption of polyurethane foam in cylinders is as follows: 1 liter is enough to cover a wall of 1 m 2 with a layer 4 cm thick. For comparison, when working with mineral wool, you will need to spend more. In addition to the material, additional elements are also needed for insulation, that is, crate, fasteners, and so on, which also costs money.
