Buy fire-resistant, fire-resistant foam in bulk. Fireproof foam for stoves Heat-resistant foam for chimneys

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. The best price among others is for the 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.

The cost of all other options remains approximately the same. An example is SOUDAFOAM FR foam, which is sold at a price of 360 rubles. DBS 9802-PUR B1 has the same price as TYTAN B1 products from a well-known 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:

  • protection of window units;
  • sealing seams between floors and ceilings;
  • to fill voids.

The depth of the cavity can reach 100 mm.

The surface temperature when applying foam can vary from +5 to +35°C. As for the foam, before use it must be kept in a room where the temperature varies from +10 to +30°C.

Conclusion

The building materials market today offers a wide range of polyurethane foam. 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 different names to products - 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 when exposed to a 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 no changes occur inside the foam for a long time.

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.

Key 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, fill the space between window and door openings, and treat 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 of the 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:

  1. Catalysts. Necessary to accelerate the expansion of the composition after application. Allows the use of the material in the cold season.
  2. Stabilizers. They are responsible for the foaming properties and uniform application of the material.
  3. Foaming agents. They play an important role in the composition because they affect the expansion coefficient and consumption of heat-resistant polyurethane foam.
  4. 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 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 is different for all manufacturers, which affects the performance characteristics of the compositions.

Additional properties:

  1. In the high temperature range from -60 to +100 degrees, the beneficial properties of polyurethane foam are fully preserved.
  2. Absolutely inert to moisture, fungus and mold formation, which are not retained by the hardened sealant.
  3. It has increased strength characteristics compared to conventional foam.
  4. 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 with cement mortar or putty, and 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 using 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 location 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 and 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 container was brought in from the cold, you need to let the tube remain warm, but do not use forced heating, which destroys the useful 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 of manufacturers:

  1. 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 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 labeling, which reflects 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-resistant polyurethane foam is used when there is a need to produce insulation that will be exposed to fire during operation.

Characteristics of fire-resistant foam

The mentioned mounting foam is a one-component sealant made on the basis of polyurethane foam. Once purchased, you can use it immediately. During the application process, its components polymerize, interacting with moisture particles contained in the external environment. Fire-resistant polyurethane foam has among its ingredients special substances that guarantee excellent acoustic and thermal properties. The resulting layer is completely impenetrable to gas and smoke.

Foam Features

Fire-resistant polyurethane foam does not burn when exposed to direct fire for the time specified by the manufacturer. After application it does not flow down, even if it ends up on a vertical surface. Among its positive characteristics is the ability to completely fill spaces of any shape. It adheres well to brick surfaces and bases made of wood, polymers, cement, steel and glass.

The material resists the effects of water and mold well, and has the ability to withstand temperature changes ranging from -60 to +100 o C. Quite often, builders and home craftsmen compare the described material with analogues that have traditional qualities. In this fight, the first version of foam emerges as the winner; it is more durable and reliable.

Fire-resistant polyurethane foam can have a different period until the moment of ignition. For example, Soudal brand material will not burn for 360 minutes when exposed to direct flame. Foam has the ability to self-extinguish. This indicates that the foam is not flammable and will not produce hot droplets if exposed to direct fire. When the flame is eliminated, the foam will go out on its own. One drawback is sensitivity to impact. This is why the foam requires protection after hardening.

Application rules

Fire-resistant polyurethane foam must be applied to a surface whose temperature is in the range from +5 to +30 o C. The operating temperature of the internal contents of the cylinder should not go beyond +10 to +30 o C. In order to prepare the foam for use, it must be kept at room temperature, but cannot be heated. It is recommended to store cylinders indoors with the neck facing up.

Fire-resistant polyurethane foam should be shaken well before application. Then you need to analyze how well it comes out of the balloon. After the output has stabilized, it is permissible to start working. In order to achieve better adhesion, it is necessary to moisten the working surface with water. However, there should be no drops on the surface. The cavities do not need to be filled more than 1/3. After a day, the foam should gain its final strength. It is recommended to cover it with plaster or sealant that has fire resistance properties.

Foam cost

Depending on the manufacturer and special additives, fire-resistant foam B1 can cost differently. The region of sale also affects the price. So, a bottle containing 750 ml of the composition can be purchased for 350 rubles.

Foam should not be applied in excess. First of all, this will lead to excess consumption of material and entail labor costs aimed at eliminating the excess after hardening. After all, the material increases in size. Therefore, before starting work, it would be good to try applying foam to a small area.

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.

  1. For filling joints in fire barriers.
  2. For reliable sealing of window and door units, including protection from fire and smoke.
  3. Sealing cracks in chimneys.
  4. As an adhesive base for insulation and insulation.
  5. 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.

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:

  • processing seams, joints and filling free space when installing or repairing stoves and fireplaces, as well as their individual components;
  • filling gaps between window or door blocks and wall elements in rooms with increased fire safety requirements;
  • filling the space between door or window blocks and walls in baths, saunas;
  • filling the space between door frames and walls in fire-fighting structures, etc.

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.

12. Fireproof foams, like all other polyurethane foams, are destroyed by ultraviolet rays.

13. Modern construction markets have a rich assortment of mounting foams from various manufacturers, including fireproof foams and foams. Which fireproof foam is best to choose depends on the preferences of the buyer, his financial capabilities and the tasks that this material must perform (meaning the fire resistance class).
