Fire-resistant polyurethane foam is used for fire insulation. This is a one-component polyurethane foam sealant, completely ready for use and polymerizing under the influence of moisture in the atmosphere.
Special substances introduced into the formulation provide excellent acoustic and thermal effects. This insulating layer does not allow smoke and gases to pass through.
Features of fire-resistant polyurethane foam
Non-flammable polyurethane foam is new material in a range of building mixtures from various manufacturers. The sealant does not flow down when processing vertical surfaces and perfectly fills any cavities. Plus excellent adhesion to brick and wood, cement and metal, glass and polymers.
Features of fire-retardant polyurethane foam:
- resistance to moisture and mold;
- ability to withstand temperature changes within the range of -60 - +100 degrees;
- higher strength and reliability (when compared with conventional foams);
- delayed ignition (the number of minutes is indicated in the characteristics of each foam; for example, for Soudal fire-resistant polyurethane foam - up to 360 minutes);
- self-extinguishing flammability - B1 according to DIN 4102 classification (this means that the product is difficult to ignite; under the influence of an open fire it does not begin to flow in hot drops, it extinguishes itself if the flame source is removed);
- Like all foams, fire-resistant foams are sensitive to ultraviolet rays and therefore require protection.
Application of fire-resistant installation sealants
Fire-resistant mounting foams are used in places where it is important to strictly comply with fire safety requirements:
Rules for using fire-resistant foams:
1. Optimal temperature the surface on which the foam will be applied - from five to thirty-five degrees.
2. Operating temperature the contents of the cylinder are ten to thirty degrees. To make the foam warm, it is kept indoors, but not heated.
3. Cylinders with polyurethane foam should be stored when room temperature neck up.
4. Before use, shake the aerosol package well. Then they check the quality of the foam coming out of the cylinder. When the output stabilizes, you can start working.
5. For better adhesion, it is advisable to spray the working surface with water. But droplets cannot be allowed to form.
6. The cavities are filled no more than a third.
7. After a day, the foam completely hardens. It can be covered with plaster or fire-resistant sealant.
Manufacturers of fire-retardant foams
When purchasing, look at the foam manufacturer. It's good if it's a trusted brand. For “newbies”, check their fire resistance certificates.
Here are a few more secrets of choice:
1. Cylinder weight.
The cheaper the foam, the less volume of material inside the aerosol package. For comparison, take two cylinders of the same volume, but different in price. And evaluate their weight in your hands.
2. Name of the foam.
Read carefully, rather than recognizing individual letters. There are craftsmen who copy the names of famous brands. Compare: fire-resistant mounting foam Souda Foam FR from a Belgian manufacturer and fire-resistant sealant Soda Pu Foam from a Chinese manufacturer. Their prices, of course, are different.
3. Fire resistance.
How many minutes can the foam withstand open fire (60, 120, 180, 230, 240 minutes). The higher the fire safety requirements for a room, the higher the fire resistance ratings should be.
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 can withstand high temperature melting and protect from 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-resistant polyurethane foam is used for fire insulation. Basically the material is a one-component polyurethane foam sealant that is ready to use. The composition polymerizes under the influence of moisture in the atmosphere. Among the ingredients there are special substances that provide thermal effect and acoustic properties. The insulating layer does not allow gases and dust to pass through.
Features of choice
Fire-resistant polyurethane foam is a material that does not flow down when applied to vertical surfaces and has the ability to fill any cavities. When choosing such a product, you should pay attention to its resistance to mold and moisture, if such requirements are imposed on the insulation. Among the main characteristics is the ability to endure temperature changes. Typically this range varies from -60 to +100°C.
The foam must be reliable and durable, especially when compared with conventional analogues. Manufacturers mention delayed ignition of the material. After reviewing the characteristics, you can find out how many minutes the polyurethane foam can undergo direct exposure to fire. Some materials are self-extinguishing. This indicates that the foam is not flammable and does not drip when exposed to open fire. If you remove the flame source, the layer simply goes out. Fire-resistant polyurethane foam has unique characteristics, but, like regular foam, it is not resistant to ultraviolet rays, and therefore requires protection.
Which foam is better to prefer: choice by cost
When choosing fire protection foam, you should pay attention to its cost. Best price Among others, it has a product of the brand RUSH FIRESTOP FLEX 65. You will have to pay 257 rubles for one can of foam. Professional foam DBS 9802-NBS B1 has a slightly higher price. You will have to pay 344 rubles for it. For 345 rub. You can purchase Nullifire FF 197 foam, it comes in 750 ml bottles.

DBS 9802-PUR B1 has the same cost as TYTAN B1 products from famous manufacturer. You can purchase professional mounting foam SOUDAFOAM FR GUN at the same price. It is manufactured in Belgium and has a volume of 750 ml. More expensive in cost is FOME PRO Premium FIRE BLOCK Gun Foam, which will cost the consumer 430 rubles. The volume of the cylinder remains the same.
Selecting foam based on fire resistance
If you need fire-resistant polyurethane foam, then it is important to pay attention to its main characteristics, among others, fire resistance should be highlighted. It is indicated by the manufacturer in minutes. This parameter is sometimes decisive when choosing a consumer. For example, RUSH FIRESTOP FLEX 65 and SOUDAFOAM FR exhibit fire resistance of 240 minutes. SOUDAFOAM FR CLICK & FIX is ready to last more than 360 minutes. Nullifire FF 197 is exposed to direct fire for 4 hours.
240 minutes ready to fight foam DBS 9802-PUR B1 and DBS 9802-NBS B1. Products under the SOUDAFOAM FR GUN brand have a fire resistance of up to 360 minutes. If there are not too great demands placed on the insulation conditions, then experts do not recommend overpaying for high fire resistance.
Foam selection by area of use
If you need professional fire-resistant foam, then you should pay attention to RUSH FIRESTOP FLEX 65. It is suitable for structures that are subject to increased fire resistance requirements during operation. You can use SOUDAFOAM FR to seal voids. This foam can be used for:

Conclusion
On the market building materials Today, polyurethane foam is available in a wide range. Among the huge variety, you can find fire-resistant foam, which is used when increased fire safety requirements are imposed on an object. Such compositions are able to withstand high temperatures and protect from burning and smoke.
Manufacturers assign products different names– fire-resistant, fire-resistant, fire-resistant, fire-resistant foam. But all these names mean one thing - the foam contains fire retardants, which provide the material with fire protection. Numerous tests and experiments upon exposure gas burner show that fire-resistant polyurethane foam does not melt, does not smolder or burn. When directly exposed to a fire source, it may become covered with a black crust on the surface, but inside the foam for a long time no changes occur.
When applying polyurethane foam, the composition does not flow down vertical surfaces and can penetrate into any voids and cavities, which is the main advantage of the material. When choosing a brand, you need to pay attention to the resistance of the sealant to moisture and mold.
Main features:
- Ability to withstand high temperature changes.
- Optimal level of reliability and strength of the material.
- Delayed ignition when exposed to direct fire.
- Self-extinguishing characteristics in the event of a fire.
- Fire-resistant polyurethane foam increases significantly in volume.
- Has pronounced adhesive properties.
Attention: According to the requirements of SNiP, pink and red fire-resistant foam is used to fill installation voids, seal seams when installing fireplaces, stoves, heating equipment, filling the space between window and door openings, processing cable communication channels. To prevent the foam from collapsing from direct exposure to sunlight, it must be covered.
Foam composition
To protect the house from fire and to ensure high fire safety of buildings, fire-resistant foam is used during the construction phase, which improves the characteristics of any building. Non-combustible building components serve to insulate buildings from fire in the event of a fire. Most materials are one-component polyurethane compounds, immediately ready for use. Special substances provide reliable fire protection, thermal effect and optimal sound-absorbing properties.
The material includes:
- Catalysts. Necessary to accelerate the expansion of the composition after application. Allows the use of the material in the cold season.
- Stabilizers. Responsible for foaming properties and uniform application of the material.
- Foaming agents. Execute important role in the composition, since they affect the expansion coefficient and consumption of heat-resistant polyurethane foam.
- Gas. It is necessary that when using foam it is pushed out of the container.
Dyes included in the composition are used to color fire retardant insulation bright pink or red. After application, the sealant increases in volume, but in terms of foam formation it is inferior to conventional polyurethane foam.
According to safety regulations, non-flammable polyurethane foam is recommended for use in all places with large or constant crowds of people. The choice of material depends on the level of fire hazard of the room. All types of sealants are divided into several classes according to fire resistance:
- B1 – does not support combustion, self-extinguishes if the source of fire is eliminated, retains its fire-resistant properties for a long time.
- B2 – fire-resistant mounting foam melts, releasing a small amount of toxins, the insulation self-extinguishes.
- B3 - polyurethane foam is rarely used as fire insulation, low fire resistance coefficient.
You can “read” the characteristics of the foam by the markings on the tube. Index 30 means that the sealant will retain its shape and properties for half an hour when exposed to fire; this material can be used to insulate buildings with a capacity of up to three hundred people. If 60 and EI 90 are indicated on the tube, this means that the fire-retardant polyurethane foam effectively resists fire for an hour and an hour and a half, respectively. The sealant can be used in public spaces with high traffic volumes.
When marking 120 and EI 150, the resistance is indicated as 120 and 150 minutes, so the material is suitable for insulating equipment and rooms with high temperatures - chimneys, furnaces, production workshops.
Performance characteristics
It is important to understand that fire resistance does not mean the complete impossibility of fire. The sealant resists fire for a certain time, but will catch fire if exposed for a long time. The resistance period for all manufacturers is different, which affects the performance characteristics of the compositions.
Additional properties:
- In the high temperature range from -60 to +100 degrees they are completely preserved beneficial properties polyurethane foam.
- Absolutely inert to moisture, fungus and mold formation, which are not retained by the hardened sealant.
- It has increased strength characteristics compared to conventional foam.
- When heated, it does not melt, does not drip, and has pronounced self-extinguishing properties.
The only drawback is the inability to withstand sunlight, since ultraviolet rays destroy the sealant and its properties. To protect the insulation, the foam is treated cement mortar or putty, in some cases painted.
Fire-resistant foam is presented on the market in several types, which differ in component composition, performance properties and time of resistance to an open flame. Fire-resistant polyurethane foam is classified depending on its purpose and description of its properties and fire resistance characteristics. Manufacturers produce sealants using their own technologies, adding various components to the compositions in unequal proportions, therefore fire-resistant sealants have different properties:
- According to seasonality – all-season and winter.
- In terms of composition - one-component and two-component.
- Depending on the area of use, the sealant can be either household or professional construction.
It is necessary to follow the manufacturer's recommendations for applying assembly joints and work with sealant in the specified temperature range. The type of composition is selected depending on the purpose of using the insulation for passages of various traffic areas. The fire hazard category of buildings, equipment, and communication channels is taken into account.
Area of use
Fire-resistant foam has gained wide popularity due to its good properties and characteristics. The versatility of the sealant allows it to be used in different areas of construction. Heat-resistant pink foam or red polyurethane foam is used to solve the following problems:
- Insulation of equipment for baths and saunas.
- Treatment of stoves, fireplaces, boilers.
- Foaming of heating devices.
- Rooms with high temperatures.
- Sealing of window and door openings.
- Increased fire safety conditions.
Fire-resistant materials can be used in any place if fire safety regulations require it. The sealant is used to fill assembly seams and gaps, fire partitions, and any voids in the wall space and floor slabs. The use of insulation is justified around electrical wires, sockets, switches and other areas prone to spontaneous combustion.
Important: Mounting fireproof foam for chimney pipes serves as good insulation from fire, absorbs extraneous sounds. In order for the material to provide the proper level of protection, the sealant is applied in a layer of at least 3-10 cm. For foaming the composition, the optimal temperature is 5-30 degrees, and if the cylinder was brought in from the cold, you need to let the tube remain warm, but do not use forced heating, which destroys the beneficial properties. properties of the sealant.
Many companies are involved in the production of sealants, so consumers are offered a wide selection of products. All sealants differ in composition, class, and fire resistance. Foam cylinders have different volumes and yields. To choose the right fire-resistant insulation, you need to evaluate the labeling and characteristics of the foam. Brief overview by manufacturer:
- DF is a flammable sealant, the fire resistance limit is 150 minutes. The foam is pink in color, packaged in a 0.74 liter tube, and yields 25 liters of insulating mixture.
2. CP 620 – thermally expanding foam of a two-component composition. It has improved characteristics for protection against water, steam and smoke, but produces 1.9 liters of sealant.
3. Penosil - sealant is best suited for insulating tile roofs. Effectively resists fire for 3 hours, can be used to install fireproof doors
used for domestic purposes and by professional builders. It is an all-season material; the composition can be applied at temperatures down to -15°C.
has a high threshold of fire resistance. It is imperative to apply a protective treatment to the installation. The output from the cylinder reaches 65 liters.
Russian-made - high-quality sealant that can be applied at temperatures of +5...+35°C. Available in 935 g cylinders, yields 45 liters of polyurethane foam.
7. Makroflex FR77 is a popular European quality sealant that has a wide range of uses. Used for sealing panel houses.
Professional builders often use Soudal sealant with an increased operating temperature range, budget Italian-made DKC sealant for instant insulation, and products from other well-known brands. The market offers a wide range of products.

Correct calculation of consumption
Proper sealing of installation seams, gaps and voids must be carried out taking into account the correct consumption of material. When applied, sealants form different amounts of insulation, which depends on the component composition and the size of the space being filled.
The average material consumption per 1 sq.m of treated surface is indicated by the manufacturer on the tube. But there are various nuances of work that require increasing the volume or thickness of the sealed layer. Not all foams fit equally evenly into the grooves and seams; some of the material remains around the processed gaps. Craftsmen recommend purchasing material with a reserve, and when calculating consumption, take into account several factors:
- Component composition.
- Area of space.
- Foam application option.
- Humidity of the working area.
- Volume regulating dispenser.
In specialized construction companies, when calculating the consumption of fire-resistant insulation, they take into account that the voids are filled in normal temperature conditions using professional equipment. If you need to process a window opening, lay a seam thickness of 3.5-4 cm. When installing block insulation, the average consumption of sealant is ten liters. The data indicated by the manufacturer on the container can be taken for approximate calculations, but always take into account the minimum supply of sealant, since its consumption is affected by the depth and width of the seam and the uniformity of application.
To choose high-quality foam with fire-resistant properties, you need to give preference to proven, reliable brands. You should definitely pay attention to the manufacturer’s markings, which reflect the fire resistance class, flammability of the polyurethane foam, fire resistance time and composition yield taking into account the thermal expansion coefficient. Tips from experts on using installation fire-resistant sealants:
- The quality of the material depends on the duration of resistance to an open flame.
- Before use, the can must be shaken several times to activate the catalysts.
- Be sure to clean and moisten the work surface before using sealant.
- For better adhesion of the composition, the treated area can be primed.
- Foam cans should be stored upright and shaken before use.
- For uniform application of the composition, the tube must be held to the surface at an angle of 90 degrees.
The gap is filled to a third, the rest of the volume is gained as the sealant expands.
The optimal temperature for using the material is +20+23 degrees. Unless absolutely necessary, you should not perform work in the cold season. Fire-resistant insulation provides reliable sealing of voids and seams, resists open fire well, and is an order of magnitude stronger than conventional sealants. It is recommended to use the material in all places and rooms where there is overheating of equipment, open flames and the possibility of fire cannot be excluded.
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 additives flame retardants.
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 - 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 heating systems;
- for insulating heat pipes and chimneys of stoves and fireplaces;
- when insulating internal structures (wall and roof assemblies, ceilings);
- when conducting roofing works with all types of roofs.
Fire-resistant polyurethane foam for chimneys has a corresponding 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
Polyurethane fireproof foam in its application method 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.
