Liquid insulation of the POLYNOR brand. Technical characteristics of POLYNOR (polynor)

Polynor company, which produces polyurethane thermal insulation, which is sold in user-friendly packaging.

Polynor Company

The packaging consists of small cylinders with a specially designed nozzle in the shape of a pistol. This is sprayed insulation that does not require any additional devices. You can carry out the procedure using this product yourself with your own hands. This is almost the only material of its kind that is accessible to all users. Thermal insulator Polinor has a wide range of applications.

Capacity

Other types of liquid thermal insulation are used very rarely, because this requires the help of professionals who use specially designed equipment to carry out the procedure.

Polinor is an exception; the description of this product makes it clear that working with it is easy. The polyurethane substance is sold in small cylinders with a capacity of almost 900 milliliters. All you have to do is put on the gun intended for installation. After this, liquid thermal insulation is sprayed and adheres to the applied surface. The material begins to bubble intensely and becomes larger in volume. All this occurs due to a reaction in which air is the main participant.

After the process, a foamy “coat” made of bubbles filled 90% with gas immediately appears on the structure. The resulting structure retains heat. The thermal conductivity index is 0.023-0.025 W/m×K. 70% are closed cells of the frozen layer of the product. In addition, not only the thermal insulation, but also the waterproofing properties of the structure being treated are improved.

SCOPE OF APPLICATION OF POLINOR INSULATION

Foam polyurethane thermal insulation, thanks to technical characteristics that are an order of magnitude superior to other thermal insulation materials, has always been considered the most effective way to insulate a house.

However, due to its inferiority to classic insulation in terms of availability and cost, PU thermal insulation for polyurethane insulation has not yet become as widespread as mineral wool, polystyrene foam, and polystyrene insulation produced by extrusion.

Problems with accessibility were explained by the fact that to insulate a house, which requires a fairly large amount of foam insulation, until recently it was necessary to use the services of contractors, or buy special equipment, raw materials, and delve into the basics of thermal insulation yourself.

With the advent of polyurethane insulation Polinor, the situation changed in the opposite direction. Now, in order to insulate even a large surface, you do not need to look for external contractors or invest in expensive equipment.

Polinor is a polyurethane insulation that is produced in compact cylinders, the contents of which are enough to insulate one square meter of surface, with a thermal insulation thickness of 6 centimeters.

If we compare the cost of thermal insulation with Polinor cylinders with the price that will have to be paid for insulation services to third-party organizations, the difference is more than obvious.

The average statistical cost of insulating one square meter of polyurethane foam by a team of workers today is about 1-1.5 thousand rubles per square meter, which includes the cost of insulation and work. At the same time, the price of one Polinor cylinder (per 1 m²) is approximately 500 rubles.

Polyurethane insulation Polinor

Based on the above, Polinor is an ideal option for polyurethane foam thermal insulation for private use. This material can be used to insulate the following surfaces:

Internal walls and facades of houses made of any material - brick, concrete, gas silicate blocks;
Lag floors, and any coverings with a non-load-bearing structure;
The inner surface of the pitched roof;
Attic, attic floor (Astratek liquid insulation is used);
Foundation, basement, ground floor.

The liquid form of Polinor allows it to be applied to any surface, as a result of which the material is often used to insulate sewer pipes, hot and cold water supply located outside the building.

It is worth noting that the release form of Polinor somewhat limits the possibilities of its use. Insulation cylinders do not have the level of pressure required to foam the empty space in hollow walls. Polinor is an insulation material used exclusively for spraying.

In general, as evidenced, in one working day, one person can thermally insulate approximately 80-100 square meters of insulated surface with Polinor.

Structure of hardened polyurethane Polinor 1.1 ADVANTAGES OF POLYNOR The key advantages of Polinor over other PU thermal insulation are, of course, cost-effectiveness, convenience and ease of installation. You can also highlight the following strengths of Polinor: Fast hardening - within one hour;

Mice do not eat (as well as liquid thermal insulation);
No cold bridges are formed;
Does not have a negative effect on the human body;
Does not require special expensive equipment;
Highest efficiency;
Durability;
Closed cells do not allow steam and moisture to pass through;
The material has the ability to self-extinguish in the absence of direct exposure to fire 1.2 TECHNICAL CHARACTERISTICS
Polynor sprayed polyurethane insulation has technical characteristics superior to most of the insulation on the market, such as mineral wool, polystyrene foam, and extruded polystyrene foam.
The properties of balloon Polinor are virtually identical to those of industrial polyurethane foam produced in pneumatic units.
The process of spraying Polinor insulation
Let's consider the main technical characteristics of polyurethane thermal insulation Polinor.
Thermal conductivity coefficient - 0.023 - 0.025 W/μ;
The density of hardened foam is over 28 kg/m³;
The number of closed pores in the insulation structure is no less than 70%, as in the Izospan V vapor barrier;
Moisture absorption when immersing insulation in boiling water for 90 minutes – 2%;
The upper limit of the permissible operating temperature is 121 degrees (in this mode, Polinor does not lose its characteristics for about a year);
The average durability of the material is 40-50 years;
Polinor is an elastic foam that does not collapse when deformed up to 50% of the original volume;
Resistance to wet environments – maximum;
Environmental performance – certified for internal thermal insulation of indoor residential premises.
Sprayed thermal insulation from Polinor can be applied to the surfaces of any building material. Let's consider the adhesion characteristics of PU foam in relation to some of them.
Aluminum – 1 kg/cm²;
Brick, reinforced concrete – 2.5 kg/cm²;
Plywood, wood – 1.5 kg/cm²;
Steel – 1.5 kg/cm²;
Cast iron – 2 kg/cm².
The durability of Polinor and foam insulation is determined not only by the resistance of the material to a humid environment, but also by chemical resistance.
Polinor easily tolerates direct contact with organic solvents - acetone, alcohol, toluene, gasoline, and kerosene, any vegetable oils, cement and soap solutions.
Thermal insulation by Polinor of the attic floor
Methylene chloride, chloroform, dichloroethane, and concentrated solutions of hydrochloric acid (concentration over 36%) have a negative effect on the material, under the influence of which Polinor is prone to swelling. Contact of insulation with sulfuric and nitric acid, which corrode polyurethane thermal insulation, is extremely undesirable. Some even insulate the front door.

Why is POLYNOR warmer and more profitable?

Polinor looks more efficient than other materials, including sprayed analogues, due to the low thermal conductivity coefficient and the most rational heat capacity indicators. For these reasons, it retains the temperature better and does not let heat out.

This material is more profitable both in terms of process availability, as well as for budgetary reasons.

Installation

The working surface itself is prepared: it is cleaned of dirt, dust, various stains and foreign deposits. Only in this case the level of sticking (adhesion) of Polinor will be maximum.

Scheme for applying polyurethane foam:

The prepared, cleaned surface is moistened.
The contents of the can are thoroughly shaken.
A special attachment is put on and the gun is installed. The coating layer depends on the force of pressing the trigger.
After completion of work, the remaining material is cleaned using a special cleaner.

Composition and technical characteristics

Polyurethane foam insulation is a combination of two polymer components: polyol and isocyanate. As a result of their connection, carbon dioxide is released, which foams the structure of the heat insulator. After hardening, the material forms an insulating layer filled with many cells with carbon dioxide.

Characteristics of closed cell polyurethane foam:

thermal conductivity coefficient – 0.019-0.025 W/m*K;
the number of sealed cells is about 90%;
density – 25-250 kg/m3;
moisture absorption – 1-3%;
vapor permeability – 0.02-0.05;
sound absorption – average;
There are waterproofing properties.

The density of open-cell polyurethane foam is 8-18 kg/m3, moisture absorption is up to 60%, thermal conductivity is 0.025-0.045 W/m*K. Foam with an open structure absorbs sound well .

Closed cell polyurethane foam is excellent for insulating basements, foundations and other structures in contact with the ground. The material is also suitable for external insulation. Open-cell polyurethane foam is acceptable for thermal protection of roofs, ceilings and walls, but requires a water-repellent finish .

Price

The cost of the material is one of the main arguments when choosing insulation.

The average price of 1 Polinor cylinder (1 l) is 450 rubles . Cleaning fluid and gun are purchased separately.

Polinor compares favorably with its analogues, including sprayed ones, by the economical consumption of the spray composition and the absence of costs for the purchase of expensive auxiliary equipment.

In general, this heat insulator easily justifies all the costs of its purchase and installation. And thanks to its qualities, it can rightfully be called an ultra-modern innovative material for thermal insulation.

What is the consumption of a POLYNOR cylinder?

One cylinder is enough for 1 to 1.2 m2 of insulated surface with a thickness of 5 cm.

Thermal insulation efficiency?

Thanks to the monolithic layer of POLINOR insulation, the possibility of the appearance of cold bridges is eliminated and maximum insulation efficiency is achieved.

POLYNOR has the lowest thermal insulation coefficient among polyurethane foam (0.025 W/m* 0C)!

Insulation 50 mm POLYNOR = 150 mm mineral wool = 80 mm polystyrene foam.

Is this polyurethane foam?

Polyurethane foam is not capable of producing the “torch” necessary for high-quality spraying, which is the main feature of the POLYNOR NPU.

Polynor, like polyurethane foam, is polyurethane foam. However, Polynor's properties and characteristics differ from polyurethane foam:

Low water absorption - according to this indicator, POLYNOR is among the leaders (0.01-0.03 per day from the initial volume for POLYNOR; 0.2 for mineral wool; 0.02 for expanded polystyrene; 0.14 for penoizol). Does not support combustion. The lowest thermal insulation coefficient among polyurethane foam (0.025 W/m* 0С) Predominantly closed-cell structure (70% of the cells are closed)

Properties

The main goal of Polinor is to effectively insulate a structure from noise and maintain the required temperature in it.

Being a high-class sprayed insulation, the material has the lowest thermal conductivity among analogues presented on the domestic market. So, if mineral wool has a heat saving of 0.045 W/m*deg, penoizol - 0.06, and polystyrene foam - 0.033, then for POLYNOR this figure is 0.023 W/m*deg.

It is important to note that the lower the thermal conductivity, the higher the thermal insulation characteristics, i.e. material consumption will be significantly less.

In addition, POLYNOR does not require additional treatment with a protective film and does not require the purchase of accessories for installation.

Advantages

Polyurethane material has the following obvious advantages:

High degree of adhesion to building surfaces of various qualities (possibility of using Polinor in combination with any popular building materials: brick, plastic, stone, concrete, wood).
Reduced ability of the material to ignite.
Low labor intensity, simplicity and ease of installation (no additional frames or special skills required).
Environmental friendliness and low degree of toxicity of the mixture (after complete drying it does not emit substances harmful to human health into the atmosphere).
Durability (official warranty from the manufacturer is 45 years, while the insulator serves without crumbling or sagging).
The material, due to its lightness and airiness, does not create additional load on the frame and load-bearing elements of the building.
The elasticity of the mixture makes it resistant to cracking and any mechanical vibrations during the repair process.

This sprayed insulation is biologically passive, that is, it does not attract rodents and is significantly resistant to the appearance of fungi, mold and other harmful microorganisms on the treated surface.

Flaw

It is important to understand that during the process of spraying and polymerization, the material releases harmful chemical compounds, the effects of which can be protected by using protective gloves and a respirator mask.

After the mixture hardens, it loses its toxic properties, but a faint polymer odor may persist for several days.

Spray insulation technology

At first glance, the work methodology seems simple and understandable. However, to do the job well, you need relevant experience. It is important to set up the equipment correctly , calculate the optimal spray thickness and evenly treat the surface.

Tools and equipment

To operate, you will need a low or high pressure electro-pneumatic installation. As a rule, the kit already includes hoses and a spray gun. Consumable tanks must be ordered additionally.

When choosing equipment for insulating a frame house with polyurethane foam, you need to take into account a number of parameters:

Possibility of heating the composition. The operating temperature for the chemical reaction of the components is +20-25°C; when lowered, the polyurethane may thicken - this will increase consumption and reduce the quality of the coupling.
Mobility and compactness. This quality is especially important when performing high-altitude work.
Performance. To process large areas, it is not advisable to purchase or rent a low-power unit.

In addition to equipment, you will need protective equipment : a respirator or gas mask, cotton or rubber gloves, shoes, overalls, goggles, overalls.

Consumption per 1 m2

As noted in the advantages, 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 m2 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 needed for insulation, that is, sheathing, fasteners, etc., which also costs money.

Calculation of insulation thickness

It is better to entrust calculations to specialists. When calculating the thermal insulation layer, many parameters are taken into account:

type and thickness of building material;
type of structural element: wall, roof, ceiling, etc.;
thermal conductivity coefficient of building material;
climatic conditions of the region;
qualitative characteristics of the polyurethane foam itself: type, density.

Average insulation thickness values for the central region of the Russian Federation when using polyurethane foam with closed cells:

walls – at least 50 mm;
roof, attic – 120-140 mm;
basements, floors – 50-70 cm;
foundation – 30-70 mm.

Preparatory activities

Before applying the solution, the walls of the house must be cleaned and dried - residual dirt, dust and other debris will interfere with the normal adhesion of the foam to the surface. Check the integrity of the coating; dents and cracks with a diameter of more than 5-6 mm must be removed. They must be covered with cement mortar.

The next step is to install the frame for the upcoming cladding. Make a sheathing from a wooden beam or metal profile. The frame posts must be placed strictly vertically and have a single plane.

If on the day chosen for work there is high humidity or there is rain in the forecast, then the “foam” treatment must be postponed to another time. Optimal conditions are a sunny but not hot day, the surface temperature should not exceed +30°C.

Spraying polyurethane: step-by-step instructions

The preparation of the composition depends on the form of its release. Polyurethane foam in cylinders (Polinor) is ready for use. The container must be placed in the mounting gun and shaken well.

Two-component mixtures sprayed under pressure require special preparation:

Mix the first mixture with a mixer.
Shake the second element (hardener) well.
Combine the components according to the instructions, usually the proportion is 1:1. When preparing, you must avoid getting debris and moisture into the mixture.
Fill the tank with the finished product to feed into the spray gun.

Rules for spraying polyurethane foam:

First of all, foam is applied to hard-to-reach areas: areas near the chimney, ventilation holes, walls of complex configuration.
Each subsequent layer of polyurethane foam is sprayed only after the previous one has completely hardened.
It is advisable to complete all work in one day. For large processing areas, you need to enlist the help of an assistant.
The maximum thickness of one layer is 15 mm, the minimum number of coatings is 3.
Areas that do not require thermal insulation must first be covered with dense material.
Polyurethane foam is applied from bottom to top, the composition is distributed between the elements of the sheathing.

Liquid foam

This type of insulation includes almost all foam materials based on polymer resins. The quality of the final product, including its environmental friendliness, largely depends on them. There are raw materials whose use is not permissible for residential premises due to the high toxicity of the polymer and its long-term emissions. At the same time, such materials are quite suitable for insulating technical structures or isolated building elements (if there is confidence in their insulation and the conscientiousness of the working specialists).

At the moment, such types of liquid foam as polyurethane foam, penoizol, as well as a number of products in compact cylinders are common.

Polyurethane foam (PPU)

Viscous heterochain polymers in a liquid state are used as the main component of this insulation. During chemical reactions, urethanes foam, which leads to their increase in volume by more than 50 times.

In its frozen state, polyurethane foam resembles ordinary polyurethane foam, the main difference in the structure is less porosity.

Mainly used for:

Insulation of walls of frame buildings;
Roofing structures;
House facades;
Thermal insulation of basements and lower floors.

To apply polyurethane foam, you need a special unit that first mixes and foams the insulation components, and then delivers the finished mixture under pressure to the surface to be treated. Final polymerization occurs within 24 hours, after which the finishing can be installed. Polyurethane foam is suitable for treating surfaces made of brick, concrete, wood, metal, cinder blocks and gas silicate blocks.

The average cost of work including material is 1000-1500 rubles per m2, with a layer thickness of 50 mm.

Penoizol

A budget analogue of polyurethane foam insulation, since it is based on relatively cheap, but more toxic urea-formaldehyde resin. The structure of this insulation is very similar to ordinary foam plastic, but its use is more preferable due to the absence of cold gaps in the insulating layer, characteristic of sheet and roll materials.

The density of penoizol, even in a liquid state, is noticeably lower than its urethane analogues, which does not allow its use in loaded structures. Otherwise, the scope of application is similar to polyurethane foam. Thermal insulation qualities are also not exceptional and are comparable to mineral wool, and two times less than that of the polyurethane foam described above.

Apply under pressure after pre-mixing the components and foaming. Increases in volume by no more than 30 times relative to the original mixture.

Roof insulation with foam insulation

Work together with the material costs approximately 2000 rubles per 1 cubic meter.

"Polinor"

This is a liquid insulation based on polyurethanes. A common form of release is small cylinders, similar in appearance to those for polyurethane foam. Using one cylinder you can insulate about 1 m2 of surface with a layer thickness of 6-7 cm.

The strength and thermal insulation qualities are similar to polyurethane foam, but unlike it, “Polinor” is more suitable for household use, since it does not require special equipment for application. The relatively high cost (about 500 rubles per cylinder) makes its use inappropriate over large areas.

The insulation is applied by spraying, which allows it to be used on almost any surface, for example, for thermal insulation of pipelines located outdoors.

As for filling voids in the walls, this procedure cannot be completed due to insufficient pressure in the cylinder.

"Polinor" has the following technical characteristics:

Thermal conductivity – 0.025 W/(m*K);
Moisture absorption coefficient – no more than 0.03;
No toxicity, non-flammable;
Solid density – not less than 28 kg per m3;
Retains all operational properties for 50 years;
The operating temperature should not exceed +121°C;

In addition, the mixture is quite chemically stable and does not interact with most reagents common in everyday life. Chloroform, dichloroethane, and high concentration hydrochloric acid have a negative effect (promote swelling) on Polinor. Nitric and sulfuric acids react with polyurethane, thus destroying the insulating mixture as a whole.

Release form

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

In construction stores, this thermal insulation is sold in cylinders similar to conventional foam for a gun.

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

Professional advice and customer reviews

Over several years of use, Polinor 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 new product. It is noted that it is extremely easy to install, fits perfectly on any surface and has good characteristics during operation. Thermal insulation occurs quickly and at a high level.

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

Also, consumer reviews note that Polinor insulation is quite expensive in cost, but this factor should not be decisive when choosing insulation. The speed of application and excellent characteristics will allow you to save significantly on heating the room in the future.

The material is extremely toxic, so precautions should be taken

Professionals also often prefer this material. Its light structure and ease of application can significantly reduce the time and money spent on installing insulation.

Advantages and disadvantages

There are no ideal materials among insulation materials; all have not only advantages, but also disadvantages. Polyurethane foam material has a number of advantages over other heat insulators:

Low thermal conductivity. Polyurethane foam is a good barrier to heat loss. It is perfect for internal thermal insulation, as it is enough to apply a small layer of foam.
Waterproofing properties. The composition of the material allows it to be used as waterproofing. It perfectly protects against corrosion.
No seams. The method of applying insulation (spraying) allows you to obtain a seamless layer. There are no joints formed in the areas where the foam adheres, through which the cold passes.
High adhesion. The insulation adheres well to any building materials, the surface of which has been previously cleaned of debris, dust and degreased.
Chemical neutrality. Polyurethane foam does not react chemically with other building materials and installation solutions. The insulation layer is resistant to aggressive chemicals (except petroleum products).
High strength. After the foam polymerizes, it becomes so strong that it can withstand strong mechanical loads. It can even be used to insulate foundations that are buried in the soil. During operation, polyurethane also shows high strength.
Fire safety. Due to the fact that the composition includes a fire retardant, this insulation has been awarded a fire safety certificate. The material not only ignites poorly, but also contributes to the self-extinguishing of fire.
Long service life. Polyurethane does not absorb water, thanks to which it is not destroyed by adverse weather conditions and temperature changes (with the exception of ultraviolet rays). If all conditions were met during installation, it will retain its high technical characteristics for at least 50 years.
Easy to install. Any craftsman can handle spraying insulation; there is no need to nail down brackets or install sheathing.

Disadvantages of sprayed polyurethane insulation:

The material is characterized by low ultraviolet resistance. When irradiated, the structure of polyurethane foam disintegrates, so it is always protected from the outside with decorative materials. Cement plaster, panels, and siding are used.
The work requires the use of special equipment. A compressor is required for spraying, and a construction mixer is required for mixing the components. It is not necessary to buy all this equipment; it can be rented.
It is necessary to use protective equipment. When spraying polyurethane, a large amount of carbon dioxide is released, which is harmful to humans. Work should be carried out in a respirator and overalls (or other protective clothing).
High price. Spray insulation is more expensive than other insulation materials - mineral wool or polystyrene foam.

Feasibility of use

The scope of application of sprayed thermal insulation includes:

Facades subject to mandatory protection with siding or plaster.
Internal walls and partitions in private houses and industrial premises.
Pipelines and communication systems.
Verandas, attics, attics, basements.
Premises with a small area: loggias and balconies.
Containers with complex shapes, vehicles (if thermal insulation of vans or walls is necessary).
Metal surfaces: doors in warehouses and garage doors.

Sprayed polyurethane foam is not used in layered masonry and closed frame structures due to the difficulty of access, but it does an excellent job of filling cracks and open voids. The material is suitable for both internal and external insulation; it is resistant to temperature changes and moisture. Provides trouble-free adhesion to working surfaces such as wood, concrete, steel, cast iron, aluminum, plywood, brick and glass. The limitations taken into account include the low fire safety class of the insulation (G3 - normally flammable, not supporting spontaneous combustion) and zero vapor permeability.

Advantages of the method and insulation

The main advantage of sprayed thermal insulation is the ability to create a seamless energy-saving layer on your own in an extremely short period of time. The technology does not require the installation of a frame or sheathing; the insulation has an increased quality of adhesion to almost all building structures and surfaces, regardless of their angle of inclination. The sprayed material is convenient to calculate, use and transport; exactly one cylinder is used per 1 m2. If necessary, re-application of insulation is allowed, but for most objects a standard layer of 5 mm is sufficient.

Reviews confirm the consumption and performance characteristics declared by the manufacturer; it is noted that paint and plaster adhere well to the material, and there is no accumulation of condensation on the surfaces. Not everyone considers this insulation affordable, but most are inclined to believe that its price is justified. Spraying does not require auxiliary building materials or complex equipment, and there is no need for overly thorough preparation of the working base. Sprayed insulation in cylinders is consumed without a trace, the process does not depend on the complexity of the design, insulation of hard-to-reach areas is not a problem.

Possibility of using foam fillers

Then manufacturers began to produce sprayed insulation in compact-sized cylinders, which led to a reduction in the cost of the method. To spray such a mixture of steel, complex installations and specialists in thermal insulation finishing are not needed, since the material itself is filled into small containers and the possibility of manual spraying is provided. Each cylinder is designed to cover one square meter of base (layer up to 60 mm thick). One person can process up to one hundred square meters per day.

As a result, calculations showed that working with insulation such as Polynor is much more profitable in terms of labor costs, costs for the materials themselves and surface preparation. If a professional team of workers charges up to one and a half thousand rubles for insulating one square of wall, then using Polinor insulation with the same amount of material, you need to spend only about 500 rubles. You can work independently, which eliminates the need to look for experienced workers, reduces finishing time, and saves money.

The choice of thermal insulation of this type remains the only optimal option that is available to people without special training. Foam can be used to create insulation for foundations, basements, walls inside and outside buildings made of brick, stone, concrete, and blocks. This option is also suitable for thermal insulation of non-load-bearing coatings, including floors on joists, as well as pitched roofs and attic floors.

Since Polinor is suitable for application to bases made of almost any material, it can be used as thermal insulation for plumbing fixtures and sewer pipes or fittings. In such cases, foam insulation in cylinders can be used indoors or in open areas. There is only one limitation on the use of balloon thermal insulation, which is that the material cannot be used to foam voids. It can only be applied to a dense base.

Where is the material used?

Scope of application
New generation foam insulation is used for external and internal application. Depending on the characteristics of the objects, materials with open and closed cells are used.

Spraying is carried out on the following structures:

Roofs of residential, commercial, administrative buildings and engineering structures. Since the main heat losses occur through the roof, a layer 10-15 cm thick is applied for high-quality insulation. When working in attic spaces, no additional finishing is required. Sprayed Polynor insulation, once cured, forms a durable outer skin. There are no odors or discharge.
Technological containers. The use of polyurethane foam in cylinders for insulation of various tanks helps maintain a given temperature in them with minimal energy consumption. Domestic and industrial boilers are filled with polyurethane, foam is applied to the walls of swimming pools, storage facilities and other containers for storing and transporting various liquids that require stable conditions. In addition to tanks, foam is used to insulate pipes connected to them with a diameter of 20 cm or more.
Walls. For harsh climates, Polynor insulation is an excellent solution to the problem of combating freezing of load-bearing structures. The material is in no way inferior in its characteristics to Penoplex roll insulation, surpassing it in speed of application and durability. The thickness of the layer varies between 5-10 cm depending on the type of structure and climate characteristics. Spraying is carried out inside the lattice frame, which is then covered with decorative cladding.
Floors. A thick layer of PP is an excellent protection against cold and dampness coming from the ground or unheated basements. The material is applied to a concrete slab or subfloor in a wooden house. The lathing is pre-made, which is the basis for laying the finishing or intermediate coating. Ventilation of rooms is achieved by installing vents. The recommended application layer is 7-10 cm.
Attics. Insulating these residential buildings with polyurethane foam allows you to create comfortable living conditions at any time of the year. To create a reliable barrier from cold and heat, you should spray at least 15 cm of foam. After this, the internal surfaces of the attic are sheathed with plasterboard, plywood or solid boards.

Depending on the treatment area, industrial equipment or one-time sprayers are selected.

Major manufacturers of liquid insulation for buildings (structures) or utility networks

Today, a very large number of manufacturers have begun to produce ultra-thin liquid thermal insulation. However, many of them sell ordinary paint as liquid insulation. How to make the right choice? Let's look at this issue together and present a rating of the most popular manufacturers of this thermal insulation material.

Liquid thermal insulation Astratek

The service life of this coating is 10-15 years.

Types of sprayed insulation

Sprayed ecowool
The technology of insulating objects with foam is naturally considered the most effective and promising. To achieve a high-quality result, you should familiarize yourself with the types of sprayed insulation and the procedure for their use. Products are divided into ready-to-use and those requiring preliminary preparation.

Sprayed thermal insulation in cylinders is freely available and is familiar to almost every home craftsman. Aerosol cans sold in hardware stores have a capacity of 500-1500 ml. Inside there is a liquid composition saturated with compressed air. Various models have their own bell or are designed to be installed in a special gun. Spraying is carried out after shaking and turning the product upside down by pressing the trigger. One 1000 ml can is enough to form 20 liters of foam or cover 1 m2 of surface with a layer 2 cm thick. This type of insulation can be used to treat small surfaces up to 10 m2. But even in this situation, 25 cans will be required to create a layer of 5 cm, which is the minimum acceptable when arranging buildings.

Industrial mixtures are made from several liquid components immediately before use. The raw materials consist of a base composition and a hardener. For this purpose, sealed containers, a high-pressure hose, a spray gun and a pneumatic installation are used. The optimal temperature for work is +20-25°C. Deviations lead to the solution foaming too weakly or too strongly. Both options lead to deviations in performance characteristics from the norm. If weather conditions do not meet the required conditions, the solution is heated or cooled.

The material is supplied from the bottom up, the thickness of each layer should be within 3-4 cm. To achieve the desired effect, you need to treat the surfaces 2-3 times after the previous layers have completely cured.

When using industrial equipment, you need to wear skin, eye and respiratory protection. The substance has the highest degree of adhesion and is extremely difficult to remove from the body, clothing and surfaces. Therefore, places that do not need insulation must be securely closed.

Advantages and disadvantages of Polinor

Let's start with the good:

Simple installation compared to other insulation materials, which does not require the construction of a frame and other materials (isospan film, glue, fasteners, reinforcing mesh, etc.);
Convenience when working in places with difficult access, complex geometry of the surface to be coated, as well as in limited space;
The technological process of applying Polinor does not require special equipment or electricity;
Excellent adhesion to various materials (brick, wood, foam concrete, metal, glass, etc.);
One of the best (among other traditional insulation) thermal conductivity;
Coverage speed. To apply a thermal insulation layer of 1 m², 1-2 minutes is enough;
Low consumption. One 1000 ml bottle is enough to cover 1 m² with a layer thickness of 5 cm, and thanks to the compact packaging you can always buy more without excess;
Polymerization (hardening) occurs within an hour. After which, Polinor can be coated (paint, plaster, etc.) or other protection;
Long service life, according to the manufacturer, from 35 to 50 years;
Environmental Safety. During operation it does not emit harmful substances;
In addition to thermal insulation, it provides sound insulation and does not condense;
We do not like rodents, insects, fungal mold and other biological activity.

There are so many useful and convenient things. Now I'll tell you about the disadvantages:

Low resistance to direct solar radiation, just like polyurethane foam is “afraid” of ultraviolet radiation;
Fragility with regular contact with water;
Limited temperature conditions during installation. The temperature of the cylinder at the time of the process should be in the range from + 18° to + 35°C. In this case, application is possible up to t = - 20°C.
Toxicity at work. Therefore, the use of personal protective equipment: masks, respirators, skin covering is mandatory;
Difficulty in applying a uniform layer thickness. The result is the risk of obtaining non-uniform thermal conductivity of the treated coating. But with experience, the quality of spray uniformity increases;
Limitations on layer thickness of 6 cm (this is the manufacturer’s recommendation);
Polynor is not hygroscopic, therefore it creates a sealing of the surface, which eliminates its “breathing”, and therefore the ability to absorb vapor;
The insulation is sold in cylinders, for which you need to separately purchase a construction gun with a special nozzle. If the gun or attachment is lost (broken), you will have to buy a new one. Without it, it is impossible to carry out a high-quality process (as the manufacturer claims).

We insulate OSB wall boards.
At the end of this question, it is necessary to mention an important point - the flammability of Polinor. It belongs to the so-called self-extinguishing materials, but this is only in the absence of direct and constant exposure to fire

Its flammability class is G3 (i.e., medium flammable).

Well, one more point stated by the manufacturer: POLYNOR analogues are not produced in the world and in Russia. Whether this is good news or not, depends on how you look at it... But it’s up to you to judge how balanced the pros and cons of the material are.

Economic justification for the use of Polinor

If we compare the costs of laying conventional polyurethane foam and POLYNOR thermal insulation, then many factors speak in favor of the latter.

Firstly, its use can significantly save money on paying for the work of the installation team: this insulation is easily applied independently, and there is no need for knowledge of construction and technical basics.

Based on market prices in 2014, surface treatment with an area of about 100 square meters. it cost about 50 thousand rubles. These costs are similar to the costs of insulating a structure using mineral wool or expanded polystyrene. And if we compare the one-component effective heat insulator POLYNOR with a two-component mixture in the form of polyurethane foam, then the latter will cost almost one and a half times more.

The approximate cost of 1 cylinder of polyurethane sprayer POLYNOR with a volume similar to polyurethane foams is currently approximately 450 rubles. The modern Russian market is saturated with a lot of offers for the sale of Polinor, so you can always find the most acceptable price for yourself and discuss favorable delivery conditions.

Indoor insulation Polinor is packaged in an economical container, which is why purchasing more material than necessary is practically impossible, but there are no problems in re-ordering it. Please note that the standard package contains 12 cylinders with the mixture.

Main characteristics of the material

This type of insulation, produced in Norway, appeared on the Russian market only in 2014, but today it is considered very popular and effective due to the possibility of significant optimization of costs during construction and insulation of structures.

Polynor has a unique polyurethane composition, packaged in cylinders under a pressure of about 6 atmospheres. Contacting oxygen in the air, the one-component substance is activated, as a result of which it hardens and polymerizes on any surface. Convenient nozzles allow you to spray material in the most difficult to reach places.

The main qualitative difference between the frozen Polinor and its analogues is the ratio of open and closed cells. In the polyurethane composition, almost 70% is closed, whereas in conventional polyurethane foam it is only 30%. This is what determines such qualities of Polinor as a low level of thermal conductivity, vapor absorption and immunity to moisture penetration.

The approximate consumption of the sprayed composition is 1 cylinder per 1-1.2 square meters. m of surface. In this case, the thickness of the frozen mixture will be approximately 5 mm, which is quite enough for high-quality insulation.

In terms of time costs, Polinor is significantly ahead of other mounting foams, because surface treatment of 100 sq. m with a construction team of several people will take on average only about 3.5 hours.

In this case, the configuration of the room does not matter: the mixture can be applied to the farthest corners, to the joints, to any curved and uneven elements.

Purposes of use

What can be insulated with Polinor:

residential buildings, country houses, outbuildings;
industrial buildings, workshops, garages;
baths, balconies and loggias;
roofing, floors and walls;
facades, attics, attics and basements;
communication structures and systems (pipes, tanks, tanks);
some types of transport (thermos vans, isothermal cars).

Installation features

There are special requirements for preparing the surface for applying insulation. First you need to clean it of debris, and then start removing grease stains. If this is not done, adhesion between surfaces will be significantly reduced. Work should be planned during the warm season. The recommended temperature regime for creating a heat-protective layer is within 17-20 degrees. Appropriate air temperature and low humidity levels will ensure uniform distribution of the composition throughout the work area.

You need to start insulating by studying the instructions and installing the nozzle on the cylinder. It is fixed until there is a characteristic click. Next, the cover is removed from the cross and the gun is screwed on. The nozzle is included with the heat insulator, but the gun will have to be purchased separately. The procedure for preparing the cylinder for use is performed in a vertical position. Before spraying one-component polyurethane foam, shake the container thoroughly.

The product must be distributed sequentially, forming a monolithic layer. The maximum thickness of the insulation should not exceed 5 cm. Upon completion of work, the gun is cleaned with a special solvent or mechanically.

Application area

The scope of application of the sprayed material is quite wide:

First of all, this is industrial construction. Insulation of industrial buildings is a rather long and labor-intensive process. The use of such insulation makes it possible to significantly reduce the construction period, and therefore its cost.
Insulation of heating mains. All large main pipelines are buried in the ground. This means that the insulation does not have any problems with ultraviolet rays. And the use of material for installing pipes during repairs significantly reduces the period of localization and elimination of an accident on the heating main.
Low-rise construction.

Due to its price, insulation is most widely used in low-rise construction. Only owners of private houses can afford to purchase and use this type of insulation. The main reason for the popularity of this method is the acceleration of work on insulating the perimeter of the building and the ability to use one material for any surface.

Precautionary measures

Despite the safety of the Polinor composition, it is recommended to observe the following precautions when performing insulation measures.

• When the composition is released from the cylinder, there is an increased concentration of the chemical components of the insulator, which can cause irritation of the mucous membranes of the eyes, respiratory organs, and skin. Therefore, work should be carried out in special clothing, safety glasses, a mask or a respirator.

• Do not spray the contents of the cylinder near an open flame. The presence of gas may cause a fire. It is also prohibited to combine installation with smoking cigarettes.

• In the room where thermal protection is installed, you need to open windows and doors to organize good air ventilation.

In general, working with polyurethane foam insulator Polinor, produced in cylinders, is characterized by simplicity and uncomplicated application techniques, which is confirmed by user reviews.

The most popular brands of industrial heat insulation

Ecotermix. It is made on the basis of vegetable oils, and foaming occurs due to a substance that contains water. The product has a low content of components that negatively affect human health. There are 2 grades: 300 and 600. The first is intended for application to external surfaces, and the second to internal walls. This is due to the fact that brand 300 has a closed structure, and 600 has an open structure.

Sealection 500. The material is manufactured by the American company Demilec, has an open structure and a G2 fire safety class.

Healtok Soy 200. This raw material has a closed structure. Produced from soybean oil and polymer residues. After spraying, the dimensions increase 50 times, securely fixing to surfaces of any materials, filling all existing cracks and voids.

Pros of Polynor polyurethane foam, why I chose it for insulation

Quick application. I finished 40 sq m of walls in half a day.
Filling all cracks and pores. There are some kind of cracks and voids in any walls and all this would remain under penoplex or mineral wool. Polynore fills it all, leaving no dew points.
Good thermal insulation. Before application, the temperature in the extension room was +15 degrees. After application for 6-7 hours it rose to +22 degrees. That is, the result is obvious.
