Insulating the chimney in the attic. Insulation of a metal chimney pipe: materials, nuances and methods. How to insulate a chimney pipe with your own hands: basic design parameters

Having built a bathhouse, you need to take care of the safety of your loved ones. The main danger is live fire. If you do not properly insulate the chimney, stove, ceiling and walls, the ceiling may catch fire. According to fire department statistics, in 2014, 70% of bathhouse fires occurred due to improper pipe insulation. We care about our readers and will tell you how to insulate a pipe in a bathhouse with your own hands, what materials exist to protect wooden structures from fire.

The pipe in the bathhouse should be safe and retain heat well.

The chimney and stove heat up quickly. Traditionally, bathhouses are made of wood and they are easily flammable. To insulate walls, ceilings, chimneys and stoves, back in the old days they used a layer of clay, asbestos and other available materials. The main thing is that the material is a poor conductor of heat and does not ignite from high temperatures. It is necessary to protect the chimney not only for the purpose of fire safety. Condensation will not form inside the insulated structure, the chimney will cool down more slowly and will serve the owners longer.

Insulation of the furnace and pipe using foil-coated isolon.

Some people think that it is enough to cover the ceiling around the chimney with metal sheets, and the bathhouse will be completely isolated from fire. The metal heats up in the same way; it will not save you from fire. It is also not suitable as a heat insulator for a chimney.

You can line the pipe with red brick, but not every bathhouse has a similar design and size.

Modern manufacturers offer several options for insulation material chimney in the bath:

• foil insulation.

Let's look briefly at each type.

Teploizol for chimney insulation

Teploizol comparatively new material. You can insulate the material yourself. Made from polyethylene foam, which is hidden between two sheets of foil.

Teploizol withstands high temperatures well and is suitable for insulating bath pipes.

Manufacturers offer Teploizol thickness from 2 to 10 mm. The thicker the material, the higher the temperature it can withstand. For an easier presentation, consider the table:

The top foil layer will protect the chimney from strong heat. The material is easy to work with. It is wrapped around the chimney, secured with special metallized tape or wire.

Folgoizol to protect the chimney

Folgoizol consists of two layers: foil and heat insulator. Foil plays a reflective role and retains 90% of the heat in the bath. In terms of environmental friendliness, the material ranks first among similar ones, since thick food grade foil is used for production. The material is not afraid of ultraviolet radiation and high temperatures from -65 to +175 °C. Is a good insulator.

Folgoizol is coated with food foil, so it is harmless.

Often, foil insulation is used to cover not only the chimney, but also the walls and ceiling of the steam room. It is an excellent insulation, steam and water insulator for a sauna or bathhouse.

The sauna, decorated inside with foil insulation, resembles a thermos in design. The heat does not escape, the bathhouse quickly warms up and takes a long time to cool down.

Sandwich pipe - a godsend for a bathhouse

Modern manufacturers offer to install a safe sandwich pipe in a bathhouse or sauna. By choosing a sandwich chimney, you don’t have to worry about insulation. The chimney consists of several sections that are easily inserted into each other. It will be easy to assemble the structure with your own hands. A sandwich pipe is suitable for a bath or sauna with an iron stove.

The sandwich pipe immediately has built-in insulation and insulation.

The sandwich tube design resembles a multi-layer cake. The inside is a layer of stainless steel, then insulation (basalt or mineral wool) is laid, and the outside is galvanized steel. The design is modern method built-in ready-made chimney insulation. The design is designed to perform two functions at once: soot does not accumulate inside, and the outside does not overheat.

But iron stove to which the sandwich pipe is intended is mainly used in the sauna. What to do if you have a traditional Russian bathhouse with a brick stove, how to insulate it? We'll talk about this below.

How to insulate a pipe in a traditional Russian bathhouse?

To build a pipe in a bathhouse with a stone stove, red brick is used. It is not afraid of high temperatures and retains heat for a long time.

Design brick pipe must be folded correctly. How long the structure will last will depend on the quality of the masonry. When making a pipe for your bathhouse, you should not save money, since renovation work may cost more.

The pipe at the intersection with the roof, ceiling and other parts of the roof structure must be insulated with metal sheets.

The pipe outlet on the ceiling and through the roof must be insulated from high temperatures using asbestos sheets. And the walls near the inside of the pipe are lined with galvanized metal sheets. You should not use simple iron sheets, as they are susceptible to corrosion. You can make a box around the pipe in the places where it passes through the ceiling and fill it with expanded clay. It will additionally retain heat and protect wooden floors from fire.

Properly insulating a pipe is only half the battle. It is also necessary to take care of the stove, ceiling and walls of the bathhouse.

Protective insulation of the sauna stove

Modern metal stoves are simply installed on a foundation; the walls are sheathed with metal sheets on the back and sides. A stove made from metal with your own hands looks unsightly; it can be lined with red brick. It will be an additional insulator and will help maintain heat in the bathhouse.

Scheme of insulation of a stove in a bathhouse.

Previously, the stove was insulated with asbestos sheets, but at high temperatures it releases harmful substances. Therefore, we do not recommend using asbestos in a steam room.

It is more environmentally friendly to insulate the stove with natural felt. The material is expensive, but is a good insulator. The felt will not burn, but if a spark hits it, it will begin to smolder. The smell when smoldering is specific, it’s hard not to notice.

When installing the stove directly on a wooden floor, we recommend laying felt first in two layers, then making a brick cushion in three rows. The walls and floor around are insulated with metal sheets 50–70 cm high.

Proper insulation of a chimney or stove will extend the life of the chimney and heat generator, as well as protect wooden structure from fire. And after reading the article, there will be no questions about how to insulate a pipe in a bathhouse.

In this article we will talk about the best way to wrap a metal chimney pipe in order to insulate it from fire and at the same time insulate it. In general, in order to isolate a chimney duct you need to know certain rules. In general, insulation helps extend the life of the chimney.

After building a house, carrying out work on roof insulation, and insulating it, it’s time to start waterproofing the channels. There are several positive aspects to such work, which we will look at later. So, insulating a chimney pipe allows you to:

1. Reduce thermal energy consumption, it is noticeably reduced.
2. Preserve and secure the passage through the roof itself.
3. Ensure high wear resistance of the structure.
4. Create a certain interior style without relying on a pipe.

In principle, there are no special difficulties this work should not cause, but it is still worth understanding that in order to properly insulate, you need to choose the type of insulation that is suitable specifically for your home and performs the functions assigned to it.

Selection of material for thermal insulation

There is no particular difference between insulating the chimney in the house or insulating the chimney in the bathhouse. The choice of insulation must be approached extremely responsibly and under no circumstances should you purchase cheap materials that will not last the required period. The main requirements for insulation must be based on two factors:

• non-flammable;
• non-toxic.

The choice can be made from basalt, stone or mineral wool (glass wool). Due to their characteristics, these types of insulation can withstand quite serious temperature changes; in addition, such material can withstand even direct exposure to fire. In addition, the presence of pores allows you to retain heat.

There are also so-called multifunctional types of insulation - teploizol and folgoizol. They are excellent for insulating a chimney in a bathhouse, since the temperature there rarely exceeds 150-200 degrees.

Basalt insulation

Given its spread and popularity, we need to talk a little more about it. So, as already mentioned, it tolerates high temperatures and even direct exposure to fire. Therefore, it is possible to “cover” and insulate the channel along its entire length, even at the junction with the heat source. In addition, for a chimney on the roof, the use of such wool is simply necessary, because it is recommended to make a thermal “layer” between the ceilings from it. After all, it is non-flammable and is perfect for a chimney.

Basalt thermal insulation shell for chimneys

However, despite such wide opportunities and positive aspects, it also has disadvantages:

• There is no sufficient tightness, and all because of the presence of technological seams.
• High cost.
• Harm to health during installation may result if you tear off a piece of the material and gut it; the resulting dust will not have a positive effect on the respiratory tract.
• The ability to pass steam does not allow its use in some cases.

Stainless steel casing

The casing parts are fastened together using self-tapping screws. The casing itself must be formed from metal profiles, if you use metal sheets, then in principle you can use wood, but judging from experience, it is better to install a base of profiles.

Pipe insulation using stone wool and metal sheet

To make a box in the ceiling, you need to use a stainless steel sheet. Four identical U-shaped sheets of metal with prepared holes are cut out of it. They are connected to each other using self-tapping screws and screwed to the ceiling. After this, you need to prepare the bottom for this casing; use a similar material for it. A square is cut out according to the dimensions, and a hole is made in it for a pipe of the required diameter. After this, we fasten the bottom, insert the pipe and lay insulation.

For this kind of work on thermal insulation of chimney pipes, wood can also be used. Often taken as a basis wooden blocks, which are sheathed with OSB panels. Also, after installing the pipe in a specially cut hole, the voids are filled with insulation.

Shields made of wood and metal, expanded clay inside

Slag-reinforced concrete insulation slabs

Specifics concrete slabs has some differences, namely, using cotton wool in this case is not recommended. You can insulate using bricks or tiles. In the absence of bricks, you can use glass wool for a slag concrete slab. Also, do not forget about the finishing features; in this case, it is even recommended to use special solutions that can insulate just as well and are resistant to temperature changes.

Specifics of insulation work

The specifics include a certain stage, which depends on what insulation material was chosen and what the ceiling consists of. Pay attention to the manufacture of the chimney itself. If it is metal, then you will not have any serious problems; it will be enough to use the above plan. But the main thing is to choose the right insulation for the chimney.

Regulatory requirements for installation of thermal insulation

Regulatory rules include compliance with safety standards during work. This includes the use of special protective equipment:

• Glasses.
• Gloves.
• Respirator.

Also, take care of your tools. When working with insulation you will need various devices, without which you simply won’t be able to do anything.

Basic methods of insulation

We have already discussed the insulation of a metal chimney in particular above. Determine what the casing in the ceiling and on the roof will be made of. Special attention Pay attention to places of insulation near the outlet of the pipe, in those places the greatest temperature difference is observed.

Method of insulating a steel chimney

There is no particular difference between the insulation of a stainless steel channel and the like. Also pay attention to the transition directly in the house, as well as in the insulated part of the roof. Often, many owners are careless about arranging a channel in the attic, but in most cases it is from there that the fire begins to spread. According to the advice of many experts, it is better to completely thermally insulate the channel in an unheated room.

Gas boiler flue insulation

In this case, the same places that were discussed above need to be insulated. You can use the same materials for this as for solid fuel boilers. That is, opt for basalt or asbestos-cement slabs, with a layer of “stainless steel” covered on top.

• Stove heating is not at all uncommon in private construction, because gas pipelines do not always reach places quite remote from the city, not to mention centralized heating. But even if you have a heating system with gas or solid fuel boiler Many homeowners do not deny themselves the pleasure of making a fireplace. This work involves the need to remove the chimney through the roof and install a pipe.

  To ensure that a stove or fireplace does not create problems during operation, insulation of the chimney (stove pipe) is necessary.

  Why is chimney insulation necessary?

  The smoke exhaust system is constantly exposed to high temperatures. It is also influenced by chemically active substances and various external factors. As a result, the integrity of the chimney is threatened, the efficiency of its operation decreases, and prerequisites for shrinkage of the walls of the house appear.

  Cracks or gaps formed on the surface can cause poor traction and, as a result, cases of poisoning are possible carbon monoxide. Cases of fires due to soot combustion are also not uncommon.

  To operate the chimney safely and efficiently, as well as to extend its service life, several operations must be performed. One of them is chimney insulation.

  What you need to know before insulating your chimney pipe

  

  • To begin with, it is important to determine optimal place outlet and chimney height – two important conditions good traction.
  • For roofs made of flammable materials such as ondulin or roofing felt, it is necessary to take care of a spark arrester made of fine-mesh metal mesh.
  • In places where a brick chimney passes through the ceiling, when installing it, it is necessary to make a fluff with a thickness of one or one and a half bricks.
  • To avoid fire hazards between rafter system, ceiling or other combustible structures and chimney, leave a gap of at least 25 cm.
  • The ceiling and upper ceiling of a fireplace or stove are also separated by space for fire safety purposes:
  • for metal ones - the minimum gap is 1.5 m;
  • brick, having a two-row ceiling - maintain a distance of at least 0.5 m;
  • for products equipped with a three-row ceiling, the minimum distance is 0.25 m if the ceiling above the heating equipment is finished with non-combustible chimney materials.

  Insulation methods

  

  Chimney insulation allows you to protect it from two main destructive influences:

  • overheating of structures;
  • leaks through joints.

  That's why we'll focus on

  • insulating the chimney on the roof from water;
  • fireproof thermal insulation of a chimney.

  As a rule, complex isolation is carried out. In fact, in addition to solving only the main problems, the operating conditions of the smoke exhaust system are also improved. For example,

  • protecting the chimney from rain will prevent rotting wooden elements truss structure, ceilings, to avoid damage when wet;
  • Non-combustible chimney materials used to thermally insulate a smoke duct that runs through a cold attic not only reduce the likelihood of overheating of fire-hazardous wood elements, but also minimize the risk of condensation. And this is fraught with many complications: excessive soot deposition, corrosion or even its destruction.

  In modern construction, brick or metal chimneys are most often installed. The choice of insulation method is mainly determined by the material of the chimneys.

  How to insulate chimneys

  

  Fire insulation

  • The most effective and simple, although perhaps not entirely cheap option– installation of a ceramic or steel sandwich chimney. Internal channel this structure, through which smoke is removed, is made of heat-resistant material and insulated with basalt, stone or mineral wool, providing completely non-flammable insulation for the pipes. For the outer layer of the prefabricated structure, heat-resistant material was also used - steel or ready-made expanded clay concrete blocks. It is equipped with additional elements necessary for installation, inspection and maintenance of the chimney.
  • Another thermal insulation option is brick chimney. This material has low thermal conductivity, so walls made from it do not overheat to a dangerous state. For such a channel there is no need for additional events on insulation. It is enough to competently carry out fireproof cutting of the chimney, as well as the ceilings.

  Note

  The design of the chimney can be made easier by finishing the brick structure with a metal or ceramic pipe. Then, for their thermal insulation, a technology is used that will be described below. This approach also allows you to save money.

  Waterproofing

  Waterproofing technology is mainly selected depending on the shape chimney and material roofing. For example, for products round section roof trim made of metal or polymers is required, with rectangular cross-section use a metal apron, as well as abutment strips.

  It must be taken into account that the larger the cross-section of the pipe and the distance to ridge beam, the more difficult the operating conditions will be. The larger volume of water from precipitation and the excessive load from accumulated snow in winter create an increased risk of leaks. Accordingly, increased demands are placed on waterproofing in this case.

  How to properly insulate chimneys

  Let's sort it out various options insulation for chimneys, how and with what to insulate.

  Plastering a brick pipe

  

  Most affordable option insulating pipes through the roof , Let's say, in the bathhouse - plastering. To do this, use solutions of cement or cement with the addition of lime. As an option for a solution, take from 1 bag (25 kg) of cement following materials(in buckets):

  • water (5),
  • slaked lime (2),
  • sand, it can also be mixed with slag chips (10).

  The resulting composition at high outside temperature sets within one to two hours, in cool weather – in 5 hours. Therefore, it is recommended to prepare the plastering solution in parts.

  To ensure that the layer of plaster is not too thick, you first need to seal the cracks. Then, after leveling the differences on the surface, the walls are covered with a reinforcing mesh.

  The plaster is applied in 2 layers.

  • For the first, the solution is more liquid and resembles sour cream in consistency. The first layer is applied by spraying:

1. The surface of the wall is cleaned of dust, then slightly moistened.
2. The solution is taken onto a trowel (spatula), then poured onto the prepared surface. The resulting layer is uneven, and this is precisely what is necessary for better adhesion between the layers.

• The second layer is thicker. It is applied using a trowel over the entire surface of the canal, from the very beginning to the end.

Sheathing with asbestos cement sheets

This method allows you to save twice more heat. The essence of it is in the decoration brick walls channel with asbestos cement slabs. Gluing is carried out on a plastering solution, which is prepared using the above technology.

• After surface reinforcement metal mesh The first layer of plaster is applied using the spray method.
• The second layer is applied to the dried first layer and asbestos-cement sheets, cut to appropriate sizes, are glued onto it.

Note

Considering the lack of environmental friendliness of asbestos, this method of chimney insulation is more suitable for cold attics. It allows you to partially balance the thermal conditions inside and outside the pipe, which significantly reduces the formation of condensation, as well as improves fire protection.

For finishing brick structures You can use sheet iron. This type of cladding is done over a layer of insulation.

Creating an insulating casing

A single metal pipe not protected by insulation is the most dangerous option from a fire point of view. In addition, it does not conserve heat well, given the high thermal conductivity of the metal. Between it and structures made of wood and plastic, you need to maintain a distance of at least 60 cm. But even then you can get burned if you accidentally touch it. Therefore, the issue of isolation still remains relevant.

The simplest insulation method in such a case is to create a multilayer sandwich structure.

• The chimney is overlapped and wrapped in mats made of basalt non-combustible wool, which are thinner than 50 mm. Melting point this insulation close to 1000˚, which is much higher than the temperature of the smoke.
• A knitting steel wire is laid over the thermal insulation and secured.

• Then plaster is applied according to the technology described above, using cement-lime or clay-sand mortar.
• Instead of plaster, you can use a casing made of thin sheet iron. The sheet must have a width of at least 1 m. The metal blank is rolled along the diameter of the pipe with a layer of insulation and riveted along the edge connection line. The corners are rounded manually or using rolling rollers.

When arranging smoke exhaust ducts, you need to take into account many details. Including solving the issue of high-quality insulation. Its absence can lead to premature destruction of the chimney.

In this article you will learn what and how to isolate iron pipe for a chimney in a garage, bathhouse, private house or any other room. We'll look at everything important aspects solutions to this problem.

Why does the gas duct deteriorate?

Lack of insulation negatively affects the condition of chimneys. To avoid premature failure of the smoke exhaust system, it is necessary to resolve this issue.

The main causes of breakdowns are related to:

1. Exposure to aggressive substances. When fuel burns, a large volume of elements appears that negatively affect the metal.
   First of all, these include acids. During downtime of the smoke exhaust duct, aggressive substances settle on the walls of the chimney. This leads to the destruction of metal structures.
2. Humidity. Present in the flue high humidity. Although water vapor comes out along with smoke, a fairly large volume of condensate still remains on the walls of the structures.

Insulating the gas duct can prevent the occurrence of negative chemical processes that lead to the destruction of the system. If measures are not taken, condensate containing acids will damage the walls of the structure over time. The most dangerous period is the period of thawing of the gas duct after winter.

The importance of insulation

Creating high-quality insulation for stoves or other round flue pipes is an important preventative process. Of course this procedure will not protect the structure 100% from the negative effects of rain and other precipitation. However, insulation of metal flue ducts can significantly extend the service life of all systems.

This operation must be carried out in order to:

1. Eliminate the possibility of condensate, which contains hazardous substances, getting on the walls of pipes. chemical elements. The presence of an insulating layer will ensure their complete evaporation along with the rest of the smoke.
2. Reduce the likelihood of temperature changes in the system.
3. Create an energy-saving effect. Installing insulation reduces energy losses. The presence of this layer reduces the fuel consumption of boilers or furnaces.
4. Increasing the strength of the gas duct. Creating insulation for steel pipes helps strengthen. The frame becomes more resistant to wind loads.

It is important to choose the right material for insulation. Only in this case can the system’s resistance to low temperatures. It can also be used to eliminate the negative impact on the roof in the form of corrugated sheets or slate. These preventive measures will extend the life of the chimney.

Which material to choose?

In order to isolate steel pipe The flue must be taken into account that its heating temperature can reach three hundred degrees or more. To do this, you need to use a material that is completely devoid of flammability. For this purpose, as a rule, mineral wool, slag concrete slabs or other analogues are used. In addition, the insulation process can be carried out through the use of plaster mortar.

It is important that the weight of the insulating material is comparable to the supporting capacity of the roof. Because elements that are too heavy can damage it.

Most experts prefer mineral wool. It is lightweight and therefore ideal for this task.

You can also purchase special cylindrical insulation. They create a sufficient level of protection for the chimney. Since their design has protective layer foil. The sizes of the products in question vary. Therefore, you can easily choose an option for a pipe of the required diameter.

How to insulate a flue with your own hands?

To insulate a steel pipe, the chimney must be installed correctly. The design must comply with existing technological standards.

The following requirements apply to gas ducts:

1. A sufficient level of traction occurs only with pipes five meters or more in length.
2. The distance between the smoke exhaust structure and the roof must be at least 25 cm.
3. If the roof is made of flammable materials such as ondulin, roofing felt or slate, the pipes must be equipped with a spark arrester. Its design consists of a mesh plate that encircles the flue from above. To prevent particles of debris from getting into the spark arrester, it is covered with a special cap.

To install a gas duct, be sure to observe the fire distance between the ceiling of the room and the stove ceiling. For stainless steel structures, a distance of 1.5 meters is required.

To carry out winding of metal chimney pipes, a system diagnostic stage is required. If there are no malfunctions, then you can begin to solve the problem. Use exclusively non-flammable insulation.

Winding of stove and fireplace pipes

To equip decorative stoves that do not serve as a source of heat. It's easy to isolate them. For this purpose it will be sufficient to use a plaster solution.

The required mixture is prepared using a certain technology. First, water is poured into a special container. Then add the previously prepared dry mixture. Next, you need to mix these ingredients until a homogeneous mass is obtained.

This solution must be used to isolate the surface of the structure using a spatula.

It is distributed evenly along the entire length of the channel. Then you need to create a fiberglass reinforcing mesh. This is the only way the protective layer can last a long time.

Next, plaster is applied to the reinforcing frame. After this, the operation is repeated. This way the pipe receives reliable protection. As an alternative, mineral wool can be used. It is secured with masking tape.

The main thing is that moisture does not get on the surface of the insulation. Otherwise, the material will lose its protective properties.

Gas boiler chimney insulation

Various technologies are used to create a protective layer for chimneys. To create insulation for a gas boiler, it is best. They are considered the most effective. The design of these products consists of external and inner pipe, between which the insulation is located. These products are fireproof. They can even be used to insulate pipes from wood and other flammable materials.

To create a sandwich chimney:

• holes are created in the ceilings and the roof itself, which should be 250 mm larger than the structure itself;
• the thickness of basalt wool insulation must be at least five centimeters;
• the protective layer is fixed using wire;
• a larger size tubular product is placed on the resulting structure;
• the casing of the upper metal layer must be iron.

Next, you need to put the insulated pipes onto the furnace or boiler pipe through a hole in the ceiling or roof. After installation is complete, you need to fill out a special non-flammable material metal sheet around the riser. To solve this problem, use clay or expanded clay.

During the heating process, the liquid, which is used as a coolant, circulates throughout the system. In order not to lose useful heat and avoid excessive overheating of the room, heating pipelines are insulated.

Such work is necessary in country houses, if the heating pipelines run along the street from the boiler room, or when the boiler is located in the far wing of the building, and the pipes are stretched along cold corridors. This helps deliver more heat into the room, retaining it along the entire route: from the boiler room to the heating radiators.

Several types of insulation are used as materials; they differ in thermal conductivity and installation methods, and when choosing a material you need to know at least a little about its qualities.

Foamed polyethylene

This is a flexible insulation that is produced in the form of pipes various sizes, with a cut in the middle (this is made for ease of installation).

Installation

When insulating a pipeline with this material, pieces of insulation are applied to the pipes along the entire length and secured with construction tape. The joints or pipe connections must be covered with insulation of a thicker diameter. Therefore, before starting work you need to approximately calculate required quantity insulation different sizes.

This brand of insulation is very convenient; it can be easily cut, and the remaining pieces can be used elsewhere, making one long part from several pieces.

Fiberglass insulation

This type of insulation is most in demand among builders. This material is relatively light in weight and is not at all susceptible to rotting. That is why it is often used to insulate pipes located on the street.

Installation

During installation, the pipes are wrapped with insulation and secured with binding wire. For additional protection from moisture, the outside is tied with roofing felt or construction foil.

Basalt wool

These are shaped insulation elements, which are made in the form of plates and cylinders. Such insulation is fireproof, has good strength and does not allow moisture to pass through. Its installation is quite simple, as in the case of fiberglass insulation, it is additionally protected aluminum foil or roofing felt.

Expanded polystyrene

This insulation is made in the form of two shells of different sizes; they are fastened together using special grooves, but for a reliable connection they must be additionally secured special glue or tape.

Installation

When connecting on pipes, the halves of the insulation are connected to each other and the two parts are shifted in different directions by several centimeters. The next link is also connected, and the remaining ends are joined together, resulting in a kind of “overlap” of one connection onto another, which provides a better bond.

To insulate awkward areas and corners, shaped shells that have unequal dimensions are used.

In order to carry out high-quality insulation with this material, you need to calculate in advance the length of the pipeline, the number of joints and bends. This is necessary to purchase the required number of connecting parts.

Polyurethane foam

This insulation is applied by spraying. A specially prepared composition is sprayed onto the installed pipeline. It reliably adheres to the surface and, when foaming, forms a dense protective mass with high strength.

Due to the fact that this insulation does not withstand exposure sun rays insulation of pipes located in the open air with it must be accompanied by their protection: winding with roofing felt or aluminum foil.

For high-quality insulation of pipes, insulation materials can be combined. For example, in the boiler room and outside they can be covered with mineral wool or basalt insulation. And in the house, the connections to the heating radiators are made of foamed polyethylene, which looks more aesthetically pleasing.

This material, which is used to insulate heating pipelines, will eliminate some of the difficulties that arise during the installation of other insulation materials.

More the better…

This slogan refers to the installation of such insulation. It is applied with a spray or a regular brush, and the more layers are applied to the pipe, the better the heat will be retained. And the process itself is much easier than installing other types of insulation. It can be applied without any problems both to a smooth pipe located in good accessibility, and to hidden, inconvenient areas.

When to take care of pipeline insulation

It is best to install insulation while laying pipes and branches in the room. At this stage, it will be easier for you to select sizes (when choosing roll or tubular insulation), and in the end there will be less waste, and this, accordingly, will save money.

Insulation repair

In front of everyone positive qualities For all types of materials, it would be useful to carry out a preventive inspection of the entire heating line before the onset of the winter season. In order to avoid troubles in the future, areas of insulation that have become unusable due to some circumstances must be replaced.
