It is difficult today to imagine any repair work without special foam for sealing joints, which goes well with almost any building materials. It is not compatible only with Teflon, polypropylene, polyethylene and silicone.
Fire-resistant polyurethane foam is used for increased fire safety requirements. This composition is able to withstand high melting temperatures and protect against smoke and burning. It is used for sealing, for boilers and when installing a fire door frame.
Characteristics of fire-resistant polyurethane foam
The fire-resistant composition, unlike the usual one, is capable of expanding more strongly, due to which it is more elastic. It is also much stronger and hardens quite quickly. It can be used to fill both horizontal and various vertical joints and seams.
Before applying the composition, you need to moisten the surface with a regular sprayer.
If the size of your joint is more than 8 cm, such a joint must first be filled with brick, wood or polystyrene foam and only then use foam. For cavities less than 1 cm wide, it is better to use putty or sealant.
To make the foam composition harden faster, you need to sprinkle it with water. If one layer is not enough, then the second can be applied only half an hour after applying the first. Wet “excess” cannot be removed; it will only be smeared on the wall. You need to wait until it dries and carefully remove the “unnecessary” with a knife.
The only drawback of fire-resistant polyurethane foam is its “fear” of ultraviolet radiation. As soon as it begins to thicken, you must immediately treat it with paint, plaster, or cover it with additional boards or platbands.

fire-resistant polyurethane foam
You cannot heat cylinders with gas, as this can lead to a fire. When filling installation seams, do not forget that immediately after application it will almost triple in size, so the cavity should be filled no more than halfway.
How to choose fireproof polyurethane foam?
You simply cannot do without it during finishing construction work. In order for it to perform its main function, it is important to choose the right fire resistance and operating temperature.
When choosing foam, be sure to pay attention to the correct spelling of the brand on the cylinder, since many Chinese brands copy the name of well-known brands (for example, it is impossible to read the technical specifications on a Soda PuFoam brand cylinder).
Cylinder volumes are measured in liters and quite often buyers take the cheapest cylinders, despite the fact that these cylinders have a much smaller volume.
Which brand of fireproof polyurethane foam should I prefer?
The following brands are considered popular: Tytan, Pro Premium and Souda Foam FR.
Fireproof Tytan is produced in factories in Asia and Europe. The nominal volume of a cylinder of 750 ml costs 450-500 rubles. ($12 – 14), and the yield is 42 liters. You can blow it out at temperatures ranging from 10 to 30 degrees, and it hardens in just 30 minutes.
The Pro Premium brand is produced in Switzerland. The price for a volume of 750 ml ranges from 500 to 550 rubles. ($14 - $16). This brand has a slightly wider temperature range from +5 to +30 degrees, but also has a longer hardening time - from 8 to 12 hours. Compared to the Tytan brand, this company has a slightly larger yield - 45 liters.
An equally well-known brand is Souda Foam FR (manufacturer – Belgium). A cylinder volume of 750 ml costs from 500 to 580 rubles. ($14-17), hardening time ranges from 25 minutes to 8 hours, and temperature range from +5 to +25.
Chinese-made Soda Pu Foam is much cheaper - 290 rubles. ($8). It’s better not to buy this foam, it’s a cheap fake and it doesn’t perform its main functions.
The main advantage of fire-resistant polyurethane foam is its excellent fire resistance and fire resistance. In the event of a fire, it can withstand fire for several hours while maintaining all its performance characteristics. It is used to seal seams and cavities in stoves, and during the construction of baths and saunas it is simply impossible to do without it, since it significantly reduces heat loss in the room.
Fire safety must be ensured even at the stage of building a house and installing structures. For this purpose, professionals choose non-flammable materials. Those building components that easily melt and emit toxic gases are becoming a thing of the past, in particular polyurethane foam, which can now be fire-resistant.
Feature of the material
Polyurethane foam is a sealant that increases its volume after application. As the substance hardens, it acquires a rigid shape, this allows you to fix and hold in place door blocks, insulation, and window blocks. The base is polyurethane foam; the fire resistance of polyurethane foam is ensured by special flame retardant additives.
The main purpose of non-flammable foam is use in rooms exposed to periodic or constant heating, exposure to local heat sources:
- in workshops;
- in steam rooms and baths, in saunas;
- in treatment rooms;
- in factories;
- in entertainment establishments, etc.
Materials are divided into 2 groups according to seasonality:
- Winter ones are applied and harden at a temperature of -5...-10°C.
- Summer ones are used under normal conditions at +5°C and above.
Fire resistance class
Non-combustible material should be used wherever there is a periodic or permanent crowd of people. There are several fire resistance classes of polyurethane foam:
- B1 is the most reliable material. The foam does not support combustion, self-extinguishes when the fire source is removed, and retains its properties for a long time when exposed to fire. Suitable for use in rooms with a maximum concentration of people.
- B2 - foam with average flammability characteristics: the material melts with a slight release of toxins, but self-extinguishes when the source of heat or fire is removed. Used in low-traffic areas.
- B3 is flammable foam, rarely used in modern construction.
The characteristics of fire-resistant foam are usually given on the back of the tube, including a fire resistance coefficient. This parameter indicates the resistance time of foam to open fire when tested at a temperature of 1000°C:
- 30 indicates that the foam is capable of maintaining its shape and performance when exposed to fire for 30 minutes. The material is suitable for use in rooms with traffic capacity (capacity) of up to 300 people;
- 60 and EI 90 - polyurethane foam resists fire for 60 and 90 minutes, respectively. This material is used for insulating structures in public institutions (hospitals, public reception areas, universities, supermarkets, etc.);
- 120 and EI 150 - foam resistant to prolonged exposure to fire. It is used in buildings and workshops of increased responsibility, as well as for insulating chimneys that are subject to significant heating.
Thus, the main characteristics that you need to pay attention to when choosing a material are composition, class and fire safety coefficient.
Application
As already mentioned, polyurethane fireproof foam is used in rooms where there are constant or periodic sources of fire or intense heating. Most often, the material is used for installation of structures and communications:
- installation of window and door units;
- arrangement of sockets and switches;
- fixation of heating systems;
- for insulating heat pipes and chimneys of stoves and fireplaces;
- when insulating internal structures (wall and roof assemblies, ceilings);
- when carrying out roofing work on all types of roofs.
Fire-resistant polyurethane foam for chimneys has an appropriate designation mark; its fire resistance class is the highest. For facades, openings and other structures, you can use foam sealant EI 60 and EI 90; for a private house, you can take EI 30.
A few words about application technique
The method of application of polyurethane fireproof foam is no different from conventional polyurethane foam material. The cylinder is inserted into the construction gun and directed at an angle of 90° towards the object. The surface of the base must be cleaned of dirt and dust in advance; for reliability, you can apply 1 layer of primer.
Brand overview
The modern market offers a wide range of polyurethane foam. To be sure to choose a high-quality material, you should purchase a can from a well-known and trusted manufacturer.
Ognez
Fire-resistant polyurethane foam Ognez is produced in Russia. Some characteristics:
- Fire resistance limit - EI 240;
- Application temperature +5…+35°С;
- Operating temperature -40…-80°С.
Ognez foam can be applied in slight cold of at least +5°C, but it is necessary to heat the container itself to +18°C. The sealed material can withstand 2 freeze-thaw cycles for up to 90 days without losing its original characteristics.
Ogneza is economical: 45 liters of foam come out of a 935 g can! Affordable price is another advantage of the product from the presented brand.
Macroflex
Makroflex presents a large series of mounting foams, among which there is fire-resistant Makroflex FR77. It has a wide range of applications:
- Sealing seams during the construction of panel houses;
- Fixing windows and doors in openings;
- Laying and fixing heating pipes, sewer pipes, etc.
The material from German developers is tested in accordance with European and international standards. The brand is known for producing reliable building components that have stood the test of time.
Macroflex fire-resistant polyurethane foam is universal: its safety class is sufficient for use in public places, in residential apartment buildings and private buildings, and in industrial premises.
SOUDAFOAM FR (Soudal)
Fire-resistant mounting foam soudafoam fr is distinguished by an increased range of permissible operating temperatures and a fire resistance coefficient of EI 360. This material will ensure maximum safety for the room and people in the event of a fire - the hardened foam does not support combustion and self-extinguishes after the fire source is removed.
The applied foam polymerizes at normal humidity 60% for 2 hours at a layer of 30 mm.
Advantages of this insulator:
- High degree of protection;
- Effective consumption (from 33 to 45 liters of foam is obtained from a liter cylinder);
- High filling capacity;
- Increased adhesion to different surfaces;
- Stable layer without shrinkage and cracking;
- Available in different cylinders (with a tube or for a pistol).
Fire-resistant polyurethane foam DKC
A budget but practical foam insulator of the Italian brand, originally from China. The material is used for instant insulation and fixation of window and door openings, electrical equipment.
Fire resistance temperature +150°C. Such foam can only be used in walk-through areas with a small flow of people or in utility rooms of private houses. Operating temperature range -5…+40°С. Suitable for indoor use only.
Not everyone got houses that were built according to their own designs, taking into account all fire safety rules in the heating system. Many people have inherited houses or bought them that have already been built, where they have to remodel and maintain the chimney system.
Why a chimney system, and if the chimney is offset and when installing several stoves, basically the chimneys from them converge into one central pipe. At the same time, part of the horizontal pipes, from the outlet of the stove chimney to the central chimney, which is popularly called the “boar”, is subject to the greatest temperature changes, humidity and subsidence of structures - therefore it often cracks.
The cracks can be quite large, up to one and a half centimeters, which creates a risk of fire in the attic floor. In some regions, such chimneys are prohibited by firefighters, but in Belarus they are available, especially in village houses.
It is extremely difficult to repair a crack if the chimney constantly shifts during the heating season and summer due to temperature changes and due to incorrect installation, since fragile fireproof materials are used: clay, putty, plasters.
Scope of application and characteristics of fire-resistant foam
At the same time, the use of elastic materials based on rubber and bitumen is difficult, since they cannot withstand high temperatures and can ignite.
It is in this case that construction, fire-resistant polyurethane foam is most suitable, which, due to its elasticity, can seal moving cracks, compensating for the displacement of the horizontal chimney structure.
The heat-resistant polyurethane foam produced does not belong to the category of non-combustible foam, so it can only be used away from the firebox. So, for example, in the upper masonry of a chimney, namely, where it goes into a horizontal position. The appearance of open fire there is excluded, but if this happens, this phenomenon will be short-lived.
I would like to say right away that all foam, although it is considered fire-resistant, but according to various classifications, to the most non-combustible class EN 13501-2:205 - the fire resistance limit of the material reaches 240 minutes, you are unlikely to find foam.
The fireproof class will be indicated on the cylinder: B1 - fire-resistant or B2 - flammable but capable of extinction.

Fireproof polyurethane foam, question.
AlexKa 03-10-2017 14:31
Yesterday I saw this very foam in a construction store. The question arose, has anyone come across this or done it, is it possible to foam the space around the pipe along with the exit of the latter from the roof with this very foam. Because there are cracks through which it blows. The foam will likely touch the pipe. The outlet pipe is ordinary, not a sandwich.
Thank you in advance for your consultation. Please don't send it to Google. Was. I couldn't find a clear answer to the question. As usual there is a lot of garbage and water...
Abar 03-10-2017 14:45
I have it foamed with this foam, only in the attic, where the pipe comes out of the ceiling, but the foam comes into contact with the pipe. The pipe is a sandwich. At the point where it comes out of the roof there is a masterflash, a special rubber band.
AlexKa 03-10-2017 15:07
The rubber band is worth it. Sealed with fire-resistant sealant. A tree was chosen with reserve around the pipe. The metal remained. It's siphoning from somewhere at the joints. But the pipe coming out of the roof is ordinary. Next is the sandwich. When I was assembling it, one knee was missing, so I installed it temporarily.
Abar 03-10-2017 16:01
It’s not very clear, can you be more specific? Foam is possible if there is no hot iron there.
AlexKa 03-10-2017 16:45
Actually here it is. It was done clumsily because it was temporary because it was planned to cover the roof and bring out the sandwich through the roof. Plans changed and it remains as is. On the sides of the pipe there are gaps in the roofing sheet. It's blowing from there. If it’s just the wind, it’s not particularly strong, but when the stove is heated, it sometimes sucks in smoke. Well, sometimes it leaks when it’s raining, but it’s rare. So I wanted to foam everything around the pipe. Today I will heat the fire and feel the pipe. Does it get very hot? The sandwich, of course, doesn’t get hot...
Abar 03-10-2017 16:49
If the temperature is not too high, you can fill it with silicone, but foam, will it hold water?
AlexKa 03-10-2017 16:52
Masterflash is mounted on a temperature-resistant sealant. There is no problem there. There are gaps on the sides, one is decent. You're tired of filling it with sealant. Yes, and don’t bring a pistol to crawl up.
Abar 03-10-2017 17:12
I also had a problem with the flush, water flowed under it and flowed straight down the pipe onto the stove. As a result, another sheet of metal was placed on top of the ridge, overlapping the flash, and the entire flash was removed and placed completely on silicone. Naturally, I had to do it from the roof; there was no other way. In your case, you can put it on a fireproof sealant. You won’t get bored there, you just have to climb onto the roof and not everyone can do that. If you fill the inside with foam, water may leak over time. It may stop blowing, although I don’t really understand, well, it blows and blows, it’s not like you have an attic? Or is this not the attic in the photo?
AlexKa 03-10-2017 17:24
The photo shows the attic. There is an attic underneath. The fact that it’s blowing generally doesn’t matter, but when a strong wind pulls smoke from the chimney into the crack. And through the cracks it pulls you into the room. The house is old, frame. From the outside, the flush is placed on sealant and secured with roofing screws. Despite the fact that the iron is not smooth, nothing flows under the flush. The pipe is also coated with sealant. Of course, I did all this outside. The roofing sheets are short, the roof is made from them. It is in the area of the pipe that there are cracks in the roof itself. I used self-tapping screws, but it didn't do much good. There’s actually some kind of wild iron sandwich piled up there... In general, it’s difficult to explain with your fingers. You need a pipe properly.
Fireproof foams for ovens
Dismantle. Disassemble the roof. Cut a straighter hole. The roof in this place needs to be re-covered. Drive a sheet with an oval under the ridge. Place a pipe through it and a new masterflash also on the sealant, plus you can tighten the masterflash on top with a clamp. But this is troublesome and, well, unreasonably labor-intensive. Well, it’s not a problem to climb the fish.
Abar 03-10-2017 17:48quote: It is in the area of the pipe that there are cracks in the roof itself.
So are there gaps in the roof or between the pipe and the roof? I still don’t understand where it’s blowing? If, as you say, the sandwich is sealed and sits tightly on the sealant with self-tapping screws, and on the pipe it is coated with fire-resistant sealant, then where does the smoke go?
Can't you just deliver a sandwich? Won't this solve the problem? AlexKa 03-10-2017 18:07
I don’t know how else to explain it.. In the photo you can see iron around the pipe. On one side further and on the other closer to the pipe. This iron is there in layers. Previously there was an asbestos-cement, or whatever it is called, pipe of smaller diameter. After buying a house, I removed it. I brought a sandwich to the roof and made the exit out of ordinary stainless steel because there wasn’t enough sandwich. But it was necessary to drown. I did it temporarily. Then I planned to re-roof. It is in the layers of this metal that there are cracks. I wrote above that when there is wind, smoke blows through them. And we often have winds in the fall. Well, with heavy slanting rain, sometimes water gets in. A little. How to do it wisely is described above. Because it’s not convenient to crawl there with sealant. I saw the foam and thought that this might be a simple solution. There is a place to the left of the pipe, on the right, perhaps, the foam will touch the pipe. Or be as close as possible. This is where the question arose.

Glad if I helped - best regards.
Abar 03-10-2017 18:47
Now it’s more or less clear...I don’t think foam will help here. Maybe put a sheet of metal on top, carefully cutting a hole for the pipe? The main thing is that one edge goes under the ridge. You can even use a strip rather than a sheet and place it on sealant or mastic. Tighten with self-tapping screws. The foam may help for a while, but not for long and water will flow through it. What are the holes that are so strong that they can’t be covered with sealant? It’s okay that you can’t crawl up with a pistol, but you can use your hands carefully.
AlexKa 03-10-2017 19:24
On the left you can. On the right only if you remove the pipe. Not an option. And from the outside you won’t understand where they are, these cracks. The roof is broken, making it not very convenient to climb. Foam, in theory, will fit into any crack. And it’s not protection from water, but from blowing out. I'm drowning now. I'll check the pipe later. Although, I think, of course it’s very hot.
Regarding the sheet, I repeat, we need to take everything apart. Remove the flush, remove the pipe. And there everything is planted tightly, everything is covered. This was done in dry weather, in the summer. Now disassembling is not an option. And anyway, why redo something that works? If foam is not an option, then I won’t consider it. I just thought that this was it, a simple way to deal with a minor irritating factor.
Abar 04-10-2017 10:41
Why remove the pipe? Apply the same red sealant carefully with your hand or some kind of brush. If you can use foam, you can use sealant. Sealant is better for the roof than foam, it is more elastic, the roof heats up in the summer, cools down in the winter, moves back and forth. And the foam, if light hits it, will then begin to crumble.

Thank you very much for the consultation!
Today, the scope of application of classic fire-resistant foam has increased significantly; from now on it is used not only in the construction of window and door openings or when sealing cracks, but also as a “bridge” in places where high temperatures are expected, and this could even be a chimney. Often these are stoves or chimneys, where the temperature regime, as a rule, is constantly on the edge and as insulation, using modern means and components is much more effective and safer. In principle, there are no common characteristics between the varieties, as such, but there are significant differences in the level of fire resistance, which we will get to know a little later. In addition, we will study the features of choosing fireproof foam for a chimney.
When choosing components for construction, one should proceed from the practice of focusing not on cost, but on the specific characteristics of the product itself. In addition, pay attention to the type of chimney itself; for example, products suitable for brick trunks will not be successful for metal or combined ducts. To select polyurethane foam, you need to distinguish between the following product features:
- Resistant to moisture and mold formation and other side effects.
- Ability to withstand significant temperature deviations, ranging from -60 to +150 degrees.
- If we take the sealant as a basis for comparison, then fireproof foam has significantly greater qualities of reliability and strength.
- Properties imply delayed combustion.
- Self-extinguishing. That is, the material was used in such a classification that, when hit by direct fire, it will not flow down in burning drops, but, on the contrary, will gradually fade out.
- But, do not forget that foams, even of such characteristics as we are considering today, are quite demanding on the sun’s rays, keep in mind when processing in an open space.
Which foam is better to prefer, choice by cost?
Polyurethane foam for chimneys. Manufacturer FireBreak
Heat-resistant characteristics partly influence the cost; as a rule, if we take the average cost on the market, then one bottle will cost 400 rubles. subject to standard volume. The purchase orientation should be focused on the number of minutes of hardening, as well as the characteristics of the level of fire resistance. But, remember that the price may well exceed the mark of 500 - 600 rubles. After all, this is partly influenced by the manufacturer and his brand. You can also use cheaper heat-resistant polyurethane foam; as a rule, there are few people making counterfeits these days; at this price range it is not profitable.
Selecting foam based on fire resistance
Abesco FP200 chimney foam is EI marked
When choosing polyurethane foam, pay attention to the so-called coefficient; it indicates the level of fire resistance. On the tube itself you can find not only the basic methods for application, but also the characteristics, but also the level of fire resistance. EI marking, so:
- A value of 30 means there is a restriction on indoor use where there are gatherings of 16 to 299 people. This is subject to possible evacuation. In this case, the properties are retained for 30 minutes.
- 60 and 90 means that when heated to 1000 degrees, the properties are maintained and it is able to withstand the load. Can be used in shopping centers and large stores.
- 120 and 150 are the maximum level, they are best used to create “belts of fire” for chimneys and boilers. Sealing chimney joints can also be done using this category.
Foam selection by area of use
Heat-resistant foam should also be divided according to the scope of application, distinguishing between several main factors that were listed in the subparagraph above. So, keep in mind when working in these areas and be guided by the classification above.
- For filling joints in fire barriers.
- For reliable sealing of window and door units, including protection from fire and smoke.
- Sealing cracks in chimneys.
- As an adhesive base for insulation and insulation.
- For thermal insulation in chimneys, ventilation and air conditioning systems.
Keep in mind that when used as sealing seams in smoke exhaust ducts, you need to use a seam of at least 30 - 100 mm.
Fire-resistant fire-resistant foam, fire-resistant - a type of fire-fighting foam, which has special fire resistance characteristics and properties, is used mainly in facilities that have special fire-fighting requirements.
The high fire resistance and fire resistance of the foam allows you to maintain all the functional properties of the material even when exposed to open flames and high temperatures. The use of fire-resistant, fire-resistant foam allows not only to carry out installation and insulation work with high quality, but also to significantly save on the installation of various fire hatches and exits.
Fire-resistant fire-resistant foam is a unique material: expanding several times when sprayed, it is capable of filling a large number of voids and objects, and then, instantly hardening, securely fastening and fixing them. The use of fire-resistant, fire-resistant and fire-resistant foam to fill openings and cracks allows you to avoid the penetration of smoke and gas into the room, while at the same time combining sound and thermal insulation of the building.
Having good adhesion to various materials, fireproof foam can be easily fixed on a particular object, and its neutral color will allow all necessary finishing work to be carried out in the future. On the market you can find both household fire-fighting foam and professional fire-fighting foam, which is very convenient when choosing a material for large construction or household projects.
Before you buy fire-resistant fire-resistant foam, it is a good idea to make sure that the product has certificates of conformity confirming its unique and fire-fighting properties. The fireproof foam sold by our company has all the necessary documents that allow us to fully verify the quality and reliability of the building material.
In the event that purchasing fire-resistant foam in bulk is required for the construction of large projects, in our company you can buy fire-resistant fire-resistant foam in small and large wholesale, since these products are always in stock and will be delivered to the client as soon as possible.
Fire-resistant foam, fire-resistant in questions and answers
1. Polyurethane foam is one of the most common and popular types of sealants today, made on the basis of polyurethane with the addition of catalysts (to increase the reaction rate), foaming agents (for the cellular structure of the material), stabilizers (to form stable reactions) and other chemical elements, improving foam properties. Also, in the cylinders in which polyurethane foam is produced, there is a propellant gas, which is a mixture of gases dissolved in the polymer mass, which performs the function of pushing the foam out of the cylinder and forming air cells in the material.
2. Polyurethane foams come in one-component and two-component types. Single-component foams harden when exposed to moisture from the material and the environment. Two-component foams contain another component, thanks to which the sealant hardens in 25 - 30 minutes, and unnecessary areas can be removed in just 5 minutes.
3. Fire-fighting foam is a type of assembly sealant that has special characteristics, the main of which are fire resistance and fire resistance of the material, thanks to which it can be used in the construction or repair of objects with increased fire safety requirements.
4. Since the fire resistance of a material is its ability to maintain its functional qualities under short-term exposure to high temperatures, fire-resistant foams can withstand exposure to open fire for a long time without destruction.
5. Fire-resistant foam is classified according to flammability, or more precisely, according to flammability, which is designated on the packaging as class “B”. Thus, there are three flammability groups: B1 - the highest level of protection from exposure to open fire, B2 and B3.
6. Flammability class B1, or self-extinguishing flammability, is the ability to self-extinguish when exposed to open fire. This means that the foam mass is difficult to ignite and begins to flow in hot drops. At the same time, if you remove the source of fire, the foam itself extinguishes.
7. Depending on the fire resistance class, fire-resistant foam is excellent for:
8. When purchasing such an important material as fire-resistant foam, you need to inquire about the availability of a fire safety certificate for it, which must be present when selling goods with declared fire-resistant properties. In addition to the main document guaranteeing the fire-fighting properties of the foam, it is desirable that the documentation set include: a certificate of compliance with Russian quality standards, as well as an expert opinion, which further confirm the safety of the product and its reliability.
11. Fireproof polyurethane foam has the same characteristics as conventional polyurethane foams: excellent adhesion and cohesion, heat and sound insulation, ultimate elasticity and initial and final expansion, etc. Also, these polyurethane foams are more durable and reliable.
