Liquid foam Penomassa foam
LLC Plant TIS Channel
"Foamassa" is a liquid foam, which, during normal manual mixing in a bottle, after pouring a mixed liquid into a cavity or a mold, increases in size by 10-12 times and acquires unique physical and mechanical properties. There are many types of foam, this is the usual expanding polystyrene foam in plates and granules, extrusion plate foam, but Penomassa is a special foam, it is liquid, which in the process of polymerization increases 10-12 times and acquires the required shape with unique foam characteristics that are not inferior to conventional foams and even surpass them in many respects. "Penomassa" has an orange color, high mechanical strength (withstands compressive strength up to 33 tons per 1 sq. M.), Low water absorption (almost does not absorb moisture), low thermal conductivity (lower than that of conventional granular PSB foam and approximately the same compared to extruded foam such as Penoplex, those hnoplex), great adhesion (adhesion) to many materials, high buoyancy index (does not sink), and most importantly, it can take any shape and completely fill all voids. Penomassa liquid foam is produced according to Technical Specifications TU 2254-007-86901126 -2015 in the city of Yekaterinburg on - is intended for filling voids, cavities, thermal insulation, sound insulation, thermal insulation of building structures, making beehives, making sculptures, for filling voids in floating means, assembly joints of building structures, insulation of equipment and pipelines. "- very simple. One set of "Foam mass contains two containers", in one of which there is "foam", and in the other "mass". For the successful application of "Penomassa", both bottles must be preheated to a temperature of +20 - + 25ºС. After that, you need to open the bottle with “FOAM” and pour it into the bottle with “MASS”, close the bottle with “MASS” with a lid and shake the resulting substance in the bottle for 20-25 seconds. Then open the bottle with the resulting composition and pour it into the cavity to be filled, form. After you pour the material into the cavity to be filled, after 20 seconds the "Foam mass" will begin to increase in size by 10-12 times and fill all available cavities. "Foam mass" hardens within 2-3 minutes after pouring. Foam mass has a closed-cell structure, which prevents moisture and steam from penetrating through the material.

The use of penoizol for home insulation
Penoizol is produced by foaming urea-formaldehyde resin and its further polymerization. The convenience of this material lies in the fact that it is produced directly at the work site. Penoizol under pressure in liquid form is supplied to the insulated surface, filling it with itself. Insulation with penoizol not only significantly saves time and effort, but also has a fairly reasonable price. At the same time, money is not spent on loading and unloading operations, transport services, fastening materials, and there is no need for an area for storing insulation.
Roof insulation scheme with penoizol.
Differences and advantages of penoizol
- Penoizol differs from other materials in the peculiarity of the insulation work. The process consists in the fact that a hinged facade is initially built, and then the cavity is filled with penoizol under the vapor-conducting membrane.This method can be used to insulate walls, attics, roofs, and so on.
- Having low thermal conductivity, the material also has a low bulk density. After drying, it has a fine-mesh elastic structure, absolutely odorless. Its air absorption is almost zero, it is not hygroscopic, fungal mold does not form on its surface, and mice do not eat this insulation.
- It should be noted that working with penoizol is possible only at a certain temperature, it should not be lower than 5 ° C.
- The material is environmentally friendly, for which manufacturers must have licenses and certificates. Penoizol is not only high-quality insulation, but also excellent sound insulation.
Insulation of houses with penoizol
Wall insulation scheme.
To insulate a house, you will need a foam generator, with the help of which not only penoizol is produced, but also it is directly filled or foamed. The technology of work with this insulation allows you to fill it almost anywhere. This material is very convenient because it can be used almost anywhere. They can:
- insulate loggias and balconies;
- fill the gap between the main wall and drywall;
- to make pouring for siding, wooden floors, panels;
- insulate the bosom of the inner and outer walls.
It is very convenient to insulate ready-made, finished structures. For example, to fill voids in the walls, it is not at all necessary to disassemble the structure, it is enough to drill several holes taking into account the diameter of the steam generator hose and fill the voids with foam insulation through them. In such cases, experts recommend pouring from the bottom up.
For this job, you will need very few materials and tools.
DIY liquid foam. Description, characteristics, methods of application
Polyfoam is a lightweight and cheap material that has been used as an effective insulation for many years. And the easiest to install is penoizol - a liquid type material. In this article, we will talk about the properties and areas of application of liquid foam, about the features of its production and do-it-yourself application.
Features, positive and negative properties of liquid foam
If you decide to choose liquid foam for warming your house, first you should familiarize yourself with its characteristics. Among the advantages of this building material, the following features can be distinguished:
- Lightness is one of the main advantages. Due to its low weight, foam can be used to insulate even the smallest and most unstable structures. For example, houses with weak foundations or buildings erected on unstable soils.
- Low price. Polyfoam is considered one of the cheapest heaters, which is why it is still very popular in the construction industry. Its cost is at least half the price of polyurethane foam.
- Reviews of liquid foam indicate that such a material has excellent heat and sound insulation characteristics. According to these properties, the liquid material is not at all inferior to either its slab counterpart or polyurethane foam.
- Liquid foam is not affected by linear expansion. It perfectly tolerates temperature extremes. In addition, it does not deteriorate from ultraviolet radiation, which cannot be said about polyurethane foam.
- In liquid form, this type of foam is considered toxic, but after hardening it becomes completely harmless.
- This type of insulation is completely unattractive for either rodents or insects. That is why it is very often used in the construction of private houses.
- Polyfoam, produced in the form of a liquid substance, easily penetrates into any places, fills cavities and cracks.
- The material is considered easy to use, does not require complex skills.
In addition to the pros, liquid foam also has disadvantages:
- Insulation such as liquid foam is completely impervious to moisture.On the one hand, this is good, since in addition to insulation, the material also performs a waterproofing function. But on the other hand, the foam is completely vapor-tight, that is, it prevents normal moisture exchange between the walls of the building and the street. In such a case, the walls can flutter under a layer of insulation.
- Until the material hardens, it releases toxic substances into the environment, namely formaldehyde. Fortunately, it evaporates quickly, but, nevertheless, you need to work with insulation carefully, in a protective suit, glasses, and a respirator.
- Another disadvantage of liquid foam is the unpleasant odor. Over time, when the formaldehyde is completely volatilized, the smell disappears along with it.
Scope of application of liquid foam
Liquid foam can be used to insulate and waterproof almost any surface. Most often, the material is used on horizontal planes, namely, on attic floors in panel houses. Often, such material is used to isolate the inter-rafter space and inclined surfaces.
Since it is easier to work with a liquid than with sheet and roll material, this type of foam is simply created to insulate all kinds of sinuses and cavities. The foam supplied through the installation has a fairly dense consistency, so that it can fill the space between two stable planes. So, liquid foam is used for thermal insulation of stone formwork, false walls, wooden floors.
Various containers can be insulated with liquid foam. To do this, it is necessary to install a barrier around the container and fill the resulting space with liquid foam.
Types of liquid foam
You can watch a video of applying liquid foam with your own hands at the end of this article, but first I would like to figure out what types of material exist. It is customary to classify it according to the container and packaging in which it is produced, since such foam itself is one and the same substance. So, here are the types of liquid foam you can find on sale today:
- Industrial foam. To prepare it, you must have a special installation. It costs quite a lot, so practically no one buys it for domestic purposes. But for carrying out insulation work on an industrial scale, one cannot do without such a unit. It prepares liquid foam directly in the process and feeds it to the work surface under high pressure.
- Liquid foam in cylinders is another form of material release. These cylinders are reusable and, if necessary, recharge. A special mixture of pasty consistency is filled into one cylinder, and the catalyst is filled into the second. In the process of work, both substances combine and are supplied to the surface in the form of a ready-made liquid foam.
- There is also the so-called household liquid foam. It can also be used as glue as it is sold in small cans with a straw.
When choosing the right form of release, you should rely on future volumes of work.
Liquid foam production
As a rule, liquid foam is prepared at the place of work from several components. The finished foam is supplied to the surface through a special installation and subsequently hardens. For the preparation of liquid foam, so-called mobile stations are used.
The raw materials for the production of liquid foam used in wall insulation are resin and hardener. The components are mixed and turned into foam using a special unit. Subsequently, the foam is fed to the working base through a hose at a pressure of 5 atmospheres.
The device for the preparation of liquid foam can be purchased ready-made, but it will not cost cheap, up to 2.5 thousand dollars. You can assemble the unit with your own hands from suitable parts. The principle of the installation is quite simple.With the help of a hydraulic pump, raw materials and a catalyst - urea-formaldehyde resin - are fed into the unit. There, under the influence of compressed air, they turn into foam and under pressure through a hose they enter the treated area. Parts for the assembly of such a structure are freely available, and drawings can be found on specialized resources.
DIY liquid foam application
- First, the working base needs to be prepared. If this is not done, the material may adhere poorly to the surface and begin to flake off. And in order to ensure good adhesion, the surface to be treated, first of all, should be free of dust and dirt. So the first thing to do is to clean the base. In addition to dirt, no fats and oils should be present on the working base, which means that it should also be degreased. Also, the surface to be treated must be wet - this way the sealant will stick to it better.
- After preparing the base, you can prepare the insulation itself. To do this, the cylinder must be heated to the temperature specified by the material manufacturer. After heating, the container must also be shaken well in order to mix all the components inside the container. Please note that liquid foam should be heated in water, but never over a fire.
- The insulation can now be applied to the surface. If we are talking about household foam, then there is nothing complicated at all. Foam is applied to the surface through a tube and dispenser, or through a gun. Pressing on the valve, apply the material to the base and control the layer of insulation as you wish.
- When the foam hardens, its excess must be cut off with a knife or any convenient sharp tool. But this is only necessary if you care about the aesthetics of the surface. If the treated area is hidden and invisible, then you can do without this stage.

How to make urea liquid foam foam with your own hands.
Description of liquid foam - penoizol.
Urea insulation - foamed plastic consisting of 98% air and 2% of urea-formaldehyde resin with approximately the same number of both open and closed pores. The structure of its liquid foam is similar to the well-known meringue-type soufflé, and from afar many people confuse it with expanded polystyrene (polystyrene), but upon closer inspection, a material completely different from foam is guessed. Other names for insulation are mipora, liquid foam - penoizol, liquid insulation, urea foam, bipor and mettemplast.

Technological features of the liquid foam manufacturing process
The quality of the products must be reflected in the relevant documents.
Better to buy products directly from manufacturers. Factory material is much more expensive than one made by yourself. Liquid foam can also be obtained at home, it will not be inferior in quality to the purchased material.
The production of the material consists in mixing the carbide resin, hardener and water foam. The polymerization process is accompanied by solidification of the product. After hardening, the foam takes on a familiar shape. The material fills the holes well, in order to exclude the destruction of the hardened layer and the formation of cracks, it is necessary to supply the foam under the appropriate pressure. This prevents shrinkage of the already hardened insulation.
Insulation will significantly reduce the cost of heating the room. Independently carried out work will significantly save the budget, the cost of external insulation with liquid foam is on average $ 25. per sq. m. Sufficient pressure with which the material is supplied will ensure tight adhesion of the insulation to the surface.
Liquid foam
At the same time, sprayed heaters are known for their technological parameters, which ensure practical application:
- These materials have the highest thermal conductivity, which is about 0.020-0.028 W / mC. In more modern heaters, this figure is even lower - 0.017 W / mS
- Excellent sound insulation performance. This category of insulators successfully neutralizes even impact noise, providing quietness in the room when working with construction tools.
- The vapor permeability of sprayed heat insulators allows moisture to be absorbed without creating comfortable conditions for the formation of condensation
- The use of this material allows you to insulate even hard-to-reach places due to its consistency.
- The adhesion parameters inherent in this thermal insulating material make it possible to insulate surfaces made of any materials.
Warning. Even with all the positive feedback on the adhesion of the sprayed materials, one should not neglect their preliminary preparation. Smooth, oily, and surfaces made of polyethylene and other materials can poorly adhere to the insulation without degreasing, especially if the structure of the heat insulator is with open cells.
- The term of work with this insulation can also be called a record - 8-9 hours are enough for insulation of 100-120 square meters with low labor intensity of the process
- This is one of the few heaters, during the construction of which it is not required to equip hydro and vapor barrier
- In the characteristics of the spray-type insulation, resistance to manifestations of biological and chemical origin is also noted.
Asking the question - what kind of insulation does not mice gnaw? Another plus of sprayed insulation is that it does not arouse interest in rodents, which have become a real problem when insulating with some other categories of insulation.
Pros and cons of the material
Outwardly, penoizol is very similar to marshmallows - it is white, porous, elastic and airy. The foamy mass after manufacturing allows you to insulate a building under construction as a result of filling air voids and hollow floors and walls, it eliminates any cracks and cracks. After solidification, the mass becomes a porous heat-insulating material that fills any free space.
Penoizol has several important advantages:
- The material is very durable, it is economical and lasts a long time. On average, the service life of thermal insulation is 50-70 years;
- Reduced thermal conductivity, makes it possible to keep heat in the house, significantly reduce energy and heating costs;
- Versatility of use, they can insulate the floor, roof or foam walls;
- The penoizol layer allows air to pass through well, the material does not accumulate moisture, it “breathes”;
- Not flammable, under the influence of high temperature the layer simply evaporates gradually;
- Rats and mice do not like him and avoid him;
- Fungus and mold do not develop on it;
- Does not decompose under the influence of chemicals and organic solvents;
- Environmentally friendly insulation, will not harm human health.
Material appearance
If we compare it with the usual heat insulators, then penoizol has many positive qualities. The main ones include:
- Thermal conductivity. The minimum indicator is 0.041 W / m / K, a layer of 10 cm thick is enough for such insulation;
- Noise protection. Sound absorption about 65%;
- High temperature resistant. Refers to G1 flammability group, B2 flammability category. This says that when exposed to fire, the material does not melt. During a fire, penoizol evaporates without forming toxic substances. Compared to foam, there is 10 times less smoke;
- Chemical resistance. Does not react to aggressive influences;
- Moisture resistance. It absorbs moisture well, but also gives it away. At the same time, it does not lose its positive properties, it can absorb up to 20% moisture, after which it evaporates. To prevent the appearance of mold, it is necessary to provide a ventilation gap when laying;
- Water vapor permeability. It is hygroscopic, allowing the walls to breathe. In the thickness of the wall, air circulates without obstacles.
Wall insulation
Like any heat insulator, penoizol has its drawbacks. It is prone to shrinkage, this figure reaches 0.1-5%. This disadvantage is less in the material that fills the voids between the walls, when it expands, it turns out to be under slight pressure. During the drying of the foam, if the technology is violated and the use of low-quality raw materials, an unpleasant odor may appear.
Installation on a construction site
Important! When buying raw materials, pay attention to their smell - a quality product does not have an unpleasant smell.
Other negative properties include:
- Low tensile strength, foam is easy to break after hardening;
- Increased moisture absorption. Sometimes this drawback creates problems, for example, it cannot be used when arranging a screed and when insulating a foundation. You will need to use additional waterproofing;
- The material cannot be manufactured without special equipment;
- Temperature requirements. When pouring foam, the temperature should be above +5 degrees. Without this, high-quality foam cannot be prepared; liquid urea solution sometimes release phenol-formaldehyde. This happens if a low quality resin is purchased.
Important! Outwardly, penoizol is similar to polystyrene, they are often confused when buying. These materials really have a lot in common, the production technology allows you to make foam and foam insulation from the same raw materials. Differences are only in the manufacturing technology.
Several types of material are used for thermal insulation of houses. Their main characteristics are shown in the table.
Common varieties of penoizol | |
Name | Material difference |
Liquid | The most common type. It is used for insulation of any structures and when performing repair work. Fills any gaps and cracks well. It is permissible to prepare the material directly on the construction site. |
Granulated | Produced by grinding polymer raw materials, it is crushed into grains with a section of 10-15 mm. When used economically, granular penoizol in volume is 2 times greater than the volume of material in sheet cutting. Used to fill any voids in flooring and between walls. |
Sheet | Do-it-yourself production of penoizol at home, after which special forms are filled with the solution. After solidification, the material is cut, dried and, if necessary, further processed. Fastened from the outside of the building using dowels.It can be used to fill the voids between the lags. |
Scope of liquid urea foam
As already noted, Liquid Penoplast is absolutely universal. Today we can talk about successful application:
- For interior work (gluing light structures, thermal insulation of shower cabins, bathtubs (both tin and metal), sound insulation).
- For outdoor work (facade work, waterproofing of joints, bodywork, installation of concrete blocks (round) and a number of other areas).
The method of using foam insulation is quite simple. The surface is preliminarily cleaned of dirt, moistened with water (except for situations when the process is carried out at a temperature below 0 ° C).
According to reviews of foam in a liquid state, the optimal temperature is + 20 ° C, but if it is lower, then it is recommended to warm up the packaging in advance using a container with warm water, but not higher than 50 ° C. In hot seasons, overheated packages are also cooled with water.
We recommend that you familiarize yourself with the reviews of people who have already tested liquid foam insulation in the case to make sure that its description and characteristics are correct.
Testimonials
“Last year I faced the problem of insulating a private house. I decided to take the advice of friends and use liquid foam. In principle, I was satisfied, but the unpleasant smell lasts quite a long time in the premises, which is why after work my family and I had to move to my parents. "
Igor Rumyantsev, Chelyabinsk.
“Last fall I flooded a private house with liquid foam. I decided to do the same as my neighbors, who praised this product very much. The price of Liquid Penoplast was fine. He himself did not take up the work, he hired a team of specialists. At the end of the work, I had to move in with friends, as the house smelled terribly of chemicals. Now there is no smell, and it has become warmer. "
Nikolay, Moscow.
“In June of this year I made repairs in the apartment. Since I live on the 8th floor, the house is cold as at the North Pole. After reading reviews on the Internet, I decided to use Liquid Penoplast insulation in cylinders. In principle e, I was satisfied, and only because the price is low. The disadvantages of liquid foam are a strong pungent odor that did not disappear for a long time, a mass came out of the cylinder poorly (without pressure), which made it worn out. Maybe the reason is that I purchased a low-quality product (fake). "
Vasily, Yekaterinburg.
Insulation manufacturing technology
Making liquid foam with your own hands is quite simple with the appropriate equipment and raw materials. First, you need to prepare the installation for work. Please note that the equipment must be of high quality, and all hose connections are tight. In addition, the wiring must be able to withstand the load.
Next, you should prepare the foaming agent. To do this, you need to make 2 liters of a concentrated solution and dilute it with 48 liters of hot water. For the preparation of a foam substance, phosphoric acid of 85% concentration (half a liter) is required. It should be mixed with water (45 liters). The liquid must be heated to 40 degrees.
Now both solutions can be mixed, that is, you must combine the prepared foam with 5 liters of foaming agent. After that, the resulting solution is poured into the appropriate container.
A polymer resin is also added there, which contributes to the hardening of the foam. To improve the qualities of the material, various modifiers should be poured into it. All components are thoroughly mixed in a gas-liquid plant under the influence of compressed air. If you want to reduce the cost of construction, then try to produce liquid foam with your own hands right at the construction site.This will allow you to finish finishing work faster and will significantly reduce the cost of them.
Naturally, all actions should be performed carefully in compliance with all necessary safety standards. The point is that you will be dealing with acids. Try to wear protective clothing, gloves, and a respirator.
Thermal insulation of houses with liquid foam can reduce energy costs several times. In principle, these are all the features of the manufacture of liquid foam. Good luck!
Where to use sprayed insulation
Due to compliance with safety standards, sprayed insulation can be used for the arrangement of public and residential buildings. The range of its application is quite versatile:
- Roofing and attic structures
- Warming of floors
- Thermal insulation of wall surfaces
By objects, you can make a classification as follows:
- Industrial buildings
- Outbuildings
- Refrigeration equipment
- Pipeline communications
- Tanks for technological purposes
It is important to consider! Although spray-on insulation is considered environmentally friendly, thoughtful precautions must be taken when insulating residential buildings. At the time of application of the material, a polymerization reaction occurs, accompanied by a high degree of toxicity. And only after the final solidification, the risk of poisoning disappears completely
And only after the final solidification, the risk of poisoning disappears completely.
As for the type of materials for which it is possible to carry out insulation, there are no restrictions in this regard.
Do-it-yourself sprayed insulation
Many owners of private houses, and even apartments, try to do all the housework with their own hands. But in this case, it is not easy to do this without theoretical training and the necessary equipment.
In any case, for self-insulation with polyurethane foam, you will need a balloon installation and the components necessary for this procedure, namely:
- Polyol to be mixed in a container with freon
- Isocyanate, also combined with Freon 134
Both cylinders must be inflated until the pressure in them is at least 8 atmospheres.
Further, spraying is carried out on the treated and prepared surface - just press the spray gun and direct the stream of insulation to the desired area.
Attention! When working independently with sprayed insulation, it is imperative to use personal protective equipment!
Sprayed insulation in cylinders
Since an independent process is not as difficult as preparing it, it will be easier to immediately resort to ready-made sets of insulation in cylinders. In addition, there will be no tangible difference in cost.
Sprayed insulation in cylinders is more practical, since it has a professionally performed factory training, including the optimal pressure regime.
The price of sprayed insulation
The cost of this insulation may seem slightly higher than materials in other categories. However, the economic efficiency of this thermal insulator is obvious when calculating, of course, the cost of costs for other materials with the inclusion of additional equipment - profiles, sealants, fasteners and payment of the cost of professional work.
In the long term, the cost of insulation with sprayed insulation pays off by reducing energy costs.
Spray-on polyurethane insulation Polynor
An example of a successful choice of such insulation is the Polynor insulation. Its advantages are evidenced by reviews of the sprayed polyurethane insulation Polynor and instructions provided by the manufacturer in video format. The price for sprayed polyurethane insulation Polynor is identical to similar sprayed insulation in this category.
Thus, this type of thermal insulators is a priority in the choice of material for a number of technological indicators and for reasons of practical and budgetary value.
