How to isolate an iron chimney from the ceiling. How and than isolate the chimney pipe - the best solutions tested by time

And its insulation is a mandatory process when building, which pursues two goals: fire safety and corrosion protection.

If you do not make thermal insulation, then under the action of temperature drops, condensate will be formed, gradually flowing inside and promoting the destruction of the structure itself.

Warmed flue channels warm up faster, thereby working much more efficiently.

Depending on which the chimney of the bath is made, various materials are used for heat insulation.

There are several varieties of already insulated chimneys for bath FurnaceThe most common of which are stainless metal. A good option - Ceramic sections that are already installed in ceramzite-concrete modules.

What to warm the chimney

In the process of operation of the bath furnace, its chimney is repent, and the inevitable close arrangement to combustible materials can lead to a fire.

If the chimney pipe is composed of bricks - it is heated less, and if the chimney from the metal, then much more.

Metal pipes are split over 600 s °, and their neighborhood with wooden trim Parling is very dangerous, especially if the bath.

The second, no less important problem is the appearance of condensate in chimney. Condensate is the main enemy of all smoke-performance systems.

It is not easy moisture formed on the walls of the chimney, and water solution Sulfuric acid, which is able to destroy any almost any material. It appears as a result of the underwear of heated air in another cold chimney.

As a result of the effects of condensate on a laptile masonry, it is destroyed, as it has properties penetrate into brick microcracks, and freezing - expand. Metal chimneys also suffer from condensate.

The metal of ordinary marks is not racks to acids, therefore, from the effects of condensate, it is very quickly coming in disrepair.

The only way to combat the appearance of condensate is the isolation of smoke paths, in which the pipe will be less cool, and the bath furnace will go faster to operating the combustion mode.

Materials for insulation

Warming of chimneys can be produced various methods, with non-combustible materials.

The most common are:

  1. Heat insulation of chimney basalt cotton and glass. Heaters used for both large surfaces of brick chimneys and pipes of a relatively small diameter. Produced as a filler, in rolls or in the form of mats. It is recommended to manufacture additional casing.
  2. Method backfilling space around chimney Heat insulating material: clay, slag, brick fighting, special thermal insulation granules. This method involves the manufacture of additional chimney casing.
  3. . This is the most common, until recently, the method of insulation of brick chimneys. To this end, a slag-celastic solution applied with a layer of 5-7 cm on the reinforcing grid. After drying, a sand-cement solution was applied to it, the same thickness. But when heated and cooled the smoke system, such a insulation tried and demanded annual repairs, therefore such a method is considered unnecessary, in terms of labor costs and efficiency.
  4. Insulation chimney modern materials from foamed polyethylene. "Thermalization" or "folotosis" is produced in rolls, has low weight and good elasticity, it is well cutting, which makes it accessible to work with it even non-professional. This is the easiest and most inexpensive way to insulate the chimney, which is universally used today.

Selection of insulation

To the choice of insulation, for the isolation of the chimney, it is necessary to approach carefully and seriously. Do not purchase the cheapest, because it should have good thermal insulation properties, be convenient in work, do not require additional strengthening carrier structures Roofs and overlaps, to be non-toxic and non-combustible.

Stone or basalt wool is wonderful thermal insulation made from basalt rocks.

This insulation is withstanding the long exposure to sufficiently high temperatures and does not burn, even when contact with open fire. When heated, it does not allocate any toxic or unpleasant odors. Such a heater can be safely called an environmentally friendly material.

Glasswater is a kind of mineral wool insulation made on the basis of glass industries. Between its fibers contain a large amount of emptiness, so it retains warmth well.

The glass gamble is not lit and does not absorb moisture, is not susceptible to rotting and rodents. It is not a road and easy to use. Most often produced in plates and rolls.

Heat insole or pholoisol - these are multifunctional types of insulation, made of foamed polyethylene and aluminum foil sheet covered. It is produced in rolls and has a thickness of 2 to 10 mm. They can be wonderful to isolate the chimney of the bath, since these insulation are withstanding the heating to 150s ° -170c °.

Installation of insulation with your own hands

The chimney isolation with mineral, basalt or glass gamble can be performed in two ways: insulation under the casing or heating of chimney without casing.

In order to isolate chimney with the help of mineral wool mats, you need to cut several segments of the slab, which will fit the sides of the pipe from the outside.

After that, with the help of a wire firmware, fasten them on the chimney.

Important! There should be no emptiness between the heat insulation layer, otherwise the insulation will lose its effectiveness.

For insulation metal pipe It is necessary to wrap it with basalt cotton wool and secure the wire all over the perimeter. After that, put on the chimney the second pipe of the larger diameter, so that it turned out a kind of sandwich.

This method of thermal insulation of chimneys is the most efficient and simple, but allowing to reduce heat loss more than twice, as well as significantly reduce fire hazard and education in condensate chimping systems and protect them from destruction.

Thus, thermal insulation contributes to an increase in thermal efficiency and safe application of furnaces. At the same time, it gives the building and the design itself a more aesthetic appearance.

The flow of chimney through the overlap between the floors is the ceiling cutting - one of the most responsible stages of the construction of the bath. This is due to the high frequency of fires due to the fire of wooden structures near the chimney, namely, there are overlaps and ceiling in the baths.

Security rules dictate the need to exclude unprotected contact between hot tube and easily flammable materials. For their observance when installing the chimney in the bath, you need to build a special node for the passage of the ceiling in the form of a box using fire retardant materials, and execute it in accurately according to the standards.

Any developer can familiarize themselves with what kind of chimney equipment is considered safe, on SNIP 41-01-2003.

We are interested in paragraph 6.6.22, which dictates an indentation of 130 mm in the field of passage through the floors for the wood-made brick pipe. It is known that brick and concrete pipes have lower heat transfer than modern metal, which are most often used in the baths. This means that it is equipping the cutting of a single-alone metal pipe without heat shields, you should focus on other digits of the descendments that are specified in the "K" application:

  • 500 mm before the tree without thermal protection;
  • 380 mm from the heated pipe to the flammable layer of thermal insulation.

These numbers should be considered as distances from smoke inside the pipe to the tree.

Manufacturers of furnaces and chimneys provide documentation in which the possible value of the distance to overlaps is indicated. different materials. They should be guided by independent constructions Passage of a bath tube through the ceiling.


What materials can be used for fire protection during the PPU device?

And brick, and ceramic, and metal parts of the inter-storey cutting nodes are heated to temperatures causing the risk of wood fire. For reliable insulation, combustible elements of the ceiling cake need to perform a gasket from protective materials.

MaterialDescription

Platular fire-based material based on cement with limestone, mica and cellulose. Withstands constant heating to 150 ° C. Upon exposure to higher temperatures, the organic filler minito flashes, and it becomes fragile.

Under this common name implies a fibrous insulation consisting of molten threads of various inorganic nature. This can be like minerals (basalt, dolomite, etc.) and waste of domain production, slags. Slotovat does not lose properties to temperatures of 300 ° C, the fibers are sintering in a hotter medium - binders and hydrophobic additives are not so resistant to fire like a mineral component. As a result, thermal conductivity increases dramatically. Like fire-resistant material, the rigid mineral plate of the PJ-175 brand is positioned. It is capable of keeping insulating properties up to 1000 ° C.

Produced thickness from 2 to 10 mm. This is a material that protects perfectly from the fire, it is not only not lit, but not smoldering. The restriction on its use can be considered harm - the asbestos pair are undesirable in the bath. All gaskets from asbestos from the steam side need to close the metal.

Highly efficient and absolutely eco-friendly heat insulator, which refers to the group of non-combustible materials. Its thickness is 5 mm, the coefficient of thermal conductivity slightly grows with an increase in temperature, it works reliably at temperatures up to 900 ° C.

These are materials capable of protecting wooden parts from charring and fire at high temperatures in the zone of strong heating. But the primary cladding of the ends of the overlap, if the necessary indents are met, can be carried out not only by them. For these purposes, the use of materials having a combustible class G1 (weaklyor) is allowed.

MaterialDescription

It has GKLO designation, gray sheets with red marking. From the usual distinguished by availability internal reinforcement With a denser clutch of the layers. This prevents the penetration of oxygen into the thickness of the material, the combustion is not supported and even in open fire the material is not destroyed for 20 minutes.

The refractory properties of the degree of NG has only a marking product related to the premium class. A class sheet standard that is not labeled, it is impossible to use to protect the tree.

The selection of the heat insulator can play a decisive role. It should be remembered that the usual mineral wool, which is sometimes recommended to be used to pack the passage of the passage, it sinches and quickly loses flame retardant properties.

The high temperature leads to a change in its structure - remaining unchanged in appearance, it can heat up significantly and no longer copes with thermal insulation. For confidence in reliable thermal insulation of the chimney, it is necessary to use basalt Watu.designed for operation at temperatures 800-1000 ° C.

It is also safe to lay mineritis, asbestos or basalt cardboard. There is also a time-tested a budget option Heat shields - for her used sand (they covered the passage box) and clay. For example, sufficient thermal insulation of the part of the ceiling, to which the box is mounted, is achieved by applying a metal sheet with a flip of a smooth clay layer with a thickness of about 2 cm.

Features of using the chimney "Sandwich" when the ceiling canoe

Modern metal bath furnaces are very often complemented by steel pipes from black or stainless metal. Wanting to reduce hard IR radiation and make a safer contact of the chimney and ceiling above the furnace, the owners of the bath apply "sandwich" - a double tube with a gasket of the thermal insulating layer.






Important! The connection of chimney elements in no case should fall on the level of the passage of the ceiling overlap.

In contrast to the established opinion, the outer casing of the stainless steel sandwich is not much colder than the main chimney. This design of the pipe in principle is not to protect the bath from the fire - the sandwich provides best conditions For stable thrust, it is its main task. Considering the measures of flame retardants, it is not necessary to hope that the use of sandwich in the position of the passage makes it possible to reduce the distances of the indents.

It is known that due to the caring of the volatile compounds in the pipe itself, the temperature in it increases for some time as height increases. If at the level of outlet of the furnace gases have a temperature of 800 ° C, at the level of 1.5-2 m, the measurements will be shown already 850 ° C. The outer casing in these conditions is heated to 300 ° C, as evidenced by the colors of running on its surface.



Wanting faster to heat the bath, overheating oven, it is easy to exceed the optimal mode of passing combustion products by pipe. According to the Ministry of Emergency Situations, the temperature in stainless steel chimneys should not exceed 400 ° C, tests for certification are carried out on these values. Most couples are much higher than these parameters. From overheating, the metal quickly burns, and it is necessary to understand that the sandwich at any time can turn into a one-way. The insulation, which is clogged with a sandwich, also does not serve panacea from the fire. If you collect the chimney "on the smoke", and not "on moisture", the thermal insulator is spinning during the furnace, and after cooling it is drilled by condensate - as a result, it loses useful properties.

All of the above leads to a certain conclusion - it is not necessary to lightly reduce the recommended indents, hoping on protective casing Sandwich.

Important: when used metal stoves And stainless steel chimneys when the ceiling passage is the optimal indentation from smoke to wooden structures is 380 mm!

Stages of the ceiling cutting device

The main tasks that stand in front of the builder when arranging the passage of the chimney through the ceiling of the bath is protected from overlapping and smooth vertical installation of the pipe. Works pass in three stages:

  • definition and arrangement of the location of the cutting node;
  • installation of finished or self-made protective casing;
  • the finish gasket of heat shields.

it general rulesAnd specific methods of work depend on many factors - the allocated budget, preferences in the choice of materials, even whether technologies were observed in the construction of a bath.

The pipe passage center is determined by a plumb. The cutout is made on the markup, slightly reduce the sizes of the parties so that the future decorative panel is completely closed.

Self-made pass, as a rule, on the side of the steam room decorated with a metal sheet - galvanized or stainless steel, which simultaneously serves as a thermal screen. Sheet sizes must exceed the size of the cutout under the pipe.

  1. The vertically located chimney will pass through the ceiling overlap, and through the roof. Performing marking for chimney, you should start from the top point and use the plumb.
  2. Using ready-made PPU designs, focus on the holes recommended by the manufacturer.
  3. Changing the chimney through the overlap itself, without an industrially manufactured node, produce a preliminary calculation of the passing box. Strictly above the passage of the pipe in the ceiling cake, it is necessary to make a pass-through hole, on the dimensions allowing the required indents. They calculate them like this: for example, the diameter of the pipe is 120 mm, a sandwich with a heater is 50 mm through the overlap. The resulting external size is 230 mm. The permissible distance will be found by folding two distances of indents with an inner diameter, to smoke. According to safety standards, it is 2 * 380 + 120 \u003d 880 mm.

Important! Well, if the exact location of the bath furnace and chimney is thought out during the preparation of the project. In this case, it is easy to calculate such an installation of carrier beams of overlapping to provide the necessary space for a safe passage of the pipe between them.

Otherwise, the first thing to start work is to change the design of the overlap over the furnace. A part of the beam, too closely located to hot chimney, is cut and strengthen the installation of firmly attached to the resulting jumpers. Then overlap the ceiling.

Installation of the finished node of the cutting - passing nozzle

The advantages of using the factory construction in ease of installation and knowing the ceiling in steam room.



It is assumed that sandwich will be used as a chimney when bookmarking in the finished PPU. The dimensions of standard devices are small to ensure reliable isolation of a single chimney.

On sale there are nodes of the passage of the ceiling of various configurations. At the heart of the design is a rectangular box or round cross section, rigidly connected to a sheet that serves both to protect against heat from the bottom and for decorative finish. The center has a cutout for the pipe, the node is selected by its diameter. The finished passage structures are made of metal, most often from stainless steel, and minorite, with a laying of a thermal insulator and without it. The best in their properties are combined, having an internal metal box and an external minitite with an airflower interlayer between them.



Install the overlap pass node in this way.

  1. The holes cut into the ceiling are covered with a layer of heat insulator, turning it the tree around the perimeter.
  2. The lower sheet of the device and all the places of possible contact metal with a tree are paved with a layer of non-combustible sheet material. Here are good: minit, asbestos and foil basalt cardboard.
  3. On the knee, which will be in the node of the passage, put on the finished design and bring it to the hole carved into the ceiling. From the room the steam room, the finished node is fixed in the ceiling by self-draws, usually the holes are usually provided for the manufacturer.
  4. The diameter of the hole of the passage nozzle is always larger than the pipe diameter. The rigid binding is unacceptable due to thermal deformations, a clearance is required at least 5 mm. Based on how the material will be used as fire protection near the pipe, decide on the feasibility of isolation of the gap. If necessary, the pipe at the place of the joint is watched asbestos cord.
  5. From above, at the overlap the attic is carried out additional thermal insulation. The box is filled with clay and fire-resistant mineral wool.
  6. IN an attic room The cutting knot is left without exterior decoration. If the upper floor of the residential, the construct of the passage is decorated with a metal sheet.

Homemade Pipe Pipes through Bath Ceiling - Step-by-step instructions with photos

Necessary materials:

  • tin for the manufacture of cutting box;
  • mineritis;
  • stainless steel sheet;
  • gKLO or Basalt Carton
  • Material for filling the box - clamzit, but dry clay can come.

Pipe passage in this example is performed on the stage before finishing the ceiling. This is not fundamentally, the sequence of operations does not change.

IllustrationDescription
A tin box is made - a board is taken for the fold pattern, the edges fastened with rivets. The size of the box corresponds to the distance between the ceiling beams, if their location was thought out, taking into account the future of the chimney mounting. Indents are calculated by norms, 380 * 2 + diameter inner pipe Sandwich.
With the help of a plumbing, the center of passing the pipe is determined. Where the cargo lowered from the ceiling falls into the center of the hole for the pipe, mark the point. This will be the chimney center and the overlap pass node. Over the pipe rolls the hole. With its markup, a layer of mineritis is taken into account, which will pass around the perimeter. After its laying, the box should freely sit on the ceiling.

Stripes of Minister are laid ends of the hole, it is enough to provide thermal insulation on the edge, where the metal will come into contact with the design of the overlap.

The tin box does not have sufficient stiffness, and struts from a galvanized profile are installed to preserve its shape.
Stainless steel sheet is reproduced. Prior to the removal of the protective film, the exact location of the hole under the pipe is fixed. The cutout diameter leaves the gap between the pipe and the hole. Additionally prepare a decorative flap from the same material that covers the place of the joint. With the help of scissors for metal, the center of the received circle is cut into the sectors.
Getting started to cut the heat insulating gasket under the sheet. The template for it is the finished sheet of metal. From the tools you will need a jigsaw.
Getting started to cut the heat insulating gasket under the sheet. The template for it is the finished sheet of metal. From the tools you will need a jigsaw.

Insert the box in your place and closes the hole with a sheet of stainless steel. For confidence that in a place adjacent to the box, the ceiling is not charging and will not light up, it is done through a sheet of heat shields. Decorative pad fixes to the sheet. As a result, a reliable and beautiful screen is obtained above the oven.

The last step of work on the passage through the ceiling of the bath will be thermal insulation of the pipe in the box. For this, the refractory material will fall asleep into it until the top. Experience shows that both the sand, and the clay successfully applied for these purposes. But since the size of the box is not too small, preference should be given to a easier clay.

Mounting chimney in the bath

Chimney in the bath must be made detachable, that is, from two parts: lower and top. Not only because it will be easier to mount it, but in order to achieve the best efficiency.

Firstly, steel pipe Inside the bath will give heat, faster heating space in the steam room.

Secondly, it can be replaced, without disturbing the heat-insulating layer.

The bottom tube, departing directly from the source of fire - ovens, is heated stronger and roasts, so it needs a periodic replacement.

The connection of the parts of the riser must be produced in the middle of the attic bath. This will allow proper thermal insulation of the top of the chimney. Both pipes tend to have the same cross sectionbecause they are segments one.

The top of the riser should be insulated according to the following instruction. First of all, it is necessary to wrap it with insulation, then the diameter of the resulting structure should be measured. This size will be needed in order to determine the width of the galvanized steel sheet, from which the casing will be made for the outer tube.

Furnace installation scheme for the foundation for additional isolation.

Having received the initial data, proceed to isolation:

  • cut the two rectangles from the galvanized steel sheet and turn them around the circle, connecting the edges of the rolling;
  • cut off the same sheet of a strip of 20 cm and the length of the corresponding circumference of the riser, adding 30 mm, - we get the clamp, which we connect the lower and upper parts of the chimney;
  • on the same size, four more rings make four rings in order to close the insulation in the upper and lower ends;
  • to the end of the top of the chimney from the bottom we weld the metal strip of 4 cm wide and a thickness of 2 mm to form a pipe on which the top pipe will hold.

In the ceiling above the passing stand, you should cut the square hole in 40 cm so that the chimney is located exactly through its center. A similar hole is made in the outer roof of the bath. Then you should cut two squares from the thick sheet of metal with dimensions of 50x50 cm. They need to be fixed on the ceiling and on the roof. In the corners of the billets you need to drill holes for the subsequent fastener. In the center of metal squares should make holes equal to the diameter of the riser. On the workpiece that will be attached to the roof, the hole must be done not round, and oval, because it will need to be used to the roof slope.

Production of sandwich chimney

Further action on the installation of sandwich chimney are manufactured in the following order:

  • we wear a casing made from galvanizing, insulated with mineral wool, the ends of the segments of which should be pre-drown in the rings, bending the edge of the outer pipes to fix them;
  • the top, the warmed end of the lower riser is saturated into the round hole on the ceiling, the lower one-connecting segment of the chimney is put on the oven pipe;
  • making sure that the chimney passes exactly in the center of the hole in the ceiling, the metal sheet should be screwed to the overlap;
  • the upper part of the chimney is soaked through the hole in the roof, then just as planning it on the lower part of the riser, the finishing to the welded knives. Both parts connect the clamp;
  • screw the upper sheet of metal to the inside of the roof;
  • on the metal sheet, located around the riser, fed the ceramzite or fill it with clay or asbestos.

Scheme of the device of the sandwich tube with isolation.

However, isolation is possible by another method - by putting on the top pipe of finished segments of thermal insoles, which is able to withstand temperatures up to 1500 ° C. The heat insol is a layer of foamed polyethylene, which is covered with aluminum foil. It also carved rectangular segments that turn around the chimney to isolate it.

The material is a similar property, the material is pholoisol, the outer shell of which is made of food aluminum.

Any of these materials turns around the upper part of the chimney: from the junction from the bottom to the exit of the roofing hole. Metal clamps are used for the insulation attachment.

Before turning to wrapping the pipe with minvat, heat insoles or philisol, the outer surface of the chimney should be treated with a special heat-resistant sealant, which can withstand temperatures up to 1000 ° C. This is necessary so that the outer layer of the sandwich chimney does not slide on the surface of the metal pipe.

After the warming of the chimney should take care of sufficient waterproofing. At the point of passage of the pipe in the roof of the bath you need to install a seal using the factory sealant. To the top should be aware of a tin cap protecting the chimney from atmospheric precipitation.

  • The furnace heating is not at all uncommon in private construction, because it is not always in places, quite distant from the city, it comes to a gas pipeline, not to mention centralized heating. But even in the presence of a heating system with a gas or solid fuel boiler, many homeowners do not refuse themselves to make a fireplace. These works are associated with the need to output the chimney through the roof and the tube device.

    In order for the furnace or fireplace during operation, it is necessary to have a chimney insulation (chimney).

    What is needed isolation of flue pipes

    The smoke system is constantly experiencing high temperatures. Chemically active substances and various external factors also affect it. As a result, the integrity of the chimney is under threat, the efficiency of its work is reduced, the prerequisites for shrinkage of the walls of the house appear.

    Formed on the surface of cracks or gaps can cause bad thrust and, as a result, cases of carbon monoxide poisoning are possible. Not uncommon and cases of fires due to soot fire.

    To safely and efficiently exploit the chimney, as well as extend the service life of its service, you must perform several operations. One of them is the insulation of the chimney.

    What you need to know before isolate the chimney pipe

    • To begin with, it is important to determine the optimal output place and height of the chimney - two important conditions for good thrust.
    • For roofs from combustible materials of the Ondulin type or rubberoid, it is necessary to take care of the sparkling agent of fine metal mesh.
    • In places of passage of a brick chimney through the ceiling when it is necessary to perform a thickness of a thickness into one or a half of the brick.
    • In order to avoid fire hazardous situations between sling system, overlapping or other combustable structures and chimneys, leave the gap at least 25 cm.
    • The ceiling and the upper overlap of the fireplace or the furnace in fire for fires are also separated by space:
    • For metal - the minimum clearance is 1.5 m;
    • bricks having a two-row overlap - retain a distance of at least 0.5 m;
    • for products equipped with three-row overlap, the minimum distance is 0.25 m, if the ceiling above heating equipment Departed with non-combustible materials for chimney.

    Methods of isolation

    The isolation of the chimney allows it to protect it from two main destructive impacts:

    • overheating designs;
    • leaks through joints.

    That's why we will focus on

    • isolation of chimney on the roof of water;
    • Fireproof thermal insulation of the chimney.

    As a rule, a comprehensive isolation is carried out. At the same time, in fact, in addition to solving only the main problems, the conditions of exploitation of the smoke system are also improved. For instance,

    • The protection of the chimney from the rain will prevent the rotting of the wooden elements stropile design, overlaps, avoid its damage during wetting;
    • The non-combustible materials for the chimney used during the thermal insulation of the smoke channel, which passes through the cold attic, not only reduce the likelihood of overheating fire hazardous elements, but also minimize the risk of condensate. And this is fraught with many complications: excess deposition of soot, corrosion or even its destruction.

    IN modern construction most often installed brick or metal chimneys. The choice of isolation method is mainly determined by the material of chimneys.

    How to isolate chimneys

    Fire isolation

    • The most efficient and simple, though, perhaps, not quite a cheap option is the installation of a ceramic or steel sandwich chimney. The inner channel of this design, through which smoke is given, is made of heat-resistant material and is insulated basalt, stone or mineral wool, fully providing non-flammable insulation for pipes. For the device of the external layer of the prefabricated design, heat-resistant material - steel or ready-made ceramzit concrete blocks. It is equipped with voluntary elements needed when installing, revision and smoking service.
    • Another case of thermal insulation - brick chimney. This material has a low thermal conductivity, so the walls laid out of it are not overheated to a dangerous state. For such a channel there is no need for additional events on insulation. It is enough to competently perform the fire cutting of the chimney, as well as overlaps.

    On a note

    The design of the chimney can be facilitated, if you finish the brick design with a metal or ceramic pipe. Then, for their thermal insulation, they use the technology that will be described below. This approach also allows you to save finances.

    Waterproofing

    The waterproofing technology is predominantly choosing depending on the shape of the chimney and material roofing. For example, for round-section products, a roof cutter is needed from a metal or polymers, a metal apron is used with a rectangular cross section, as well as adjoining strips.

    It should be borne in mind that the more the cross section of the pipe and the distance to the skate bar, the more difficult the operating conditions will be. A larger amount of water from precipitation and excessive load from the accumulated snow in winter create increased risk of leaks. Accordingly, the waterproofing in this case is presented with increased requirements.

    How to isolate chimneys

    We will understand various options Insulation for chimneys, like isolate.

    Watching a brick pipe

    Most affordable option Pipe isolation through the roof , Let's say in the bath - shuttering. To do this, use solutions from cement or cement with the addition of lime. As an option for a solution of 1 bag (25 kg) cement, the following materials are taken (in buckets):

    • water (5),
    • haired lime (2),
    • sand, it can also be mixed with a slag crumb (10).

    The resulting composition at a high outer temperature is grasped for one or two hours, in the cool weather - in 5 hours. Therefore, it is recommended to prepare a solution for plastering in parts.

    In order for the layer of plaster, it is not too thick, you need to start dressing the gaps. Then after aligning the drops on the wall surface, it is tightened by the reinforcing grid.

    Plaster is applied in 2 layers.

    • For the first solution, the liquid and reminds the consistency of the sour cream. The first layer is applied by spraying method:
  1. The surface of the wall is purified from dust, then slightly moistened.
  2. The solution is taken to the trowel (spatula), then pounce on the prepared surface. The layer as a result is uneven, and this is precisely necessary for better adhesion between the layers.
  • The second layer is more dense. It is applied with the help of a trowel over the entire surface of the channel, from the very beginning to the end.

Oppression asbetic sheets

This method allows you to save twice as much heat. The essence of it in the finish brick walls Channel asbetic plates. Sticking is performed on a plaster solution that is prepared by the above technology.

  • After the surface reinforcement metal mesh Sprinkle is applied by the first layer of plaster.
  • On the dried first layer apply the second and stick to it asbestos-cement lists, cut according to the appropriate sizes.

On a note

Given the insufficient environmental friendliness of asbestos, this method of chimney thermal insulation is more suitable for cold attics. It allows partially to balance the thermal regime inside and outside the pipe, which significantly reduces the formation of condensate, as improves fire protection.

For decoration of brick structures, you can use leaf iron. Such a trim is performed on a layer of insulation.

Creating an insulating casing

A single metal pipe that is not protected by insulation is the most dangerous option, from the point of view of fire. In addition, it is badly saved by heat, given the high thermal conductivity of the metal. Between it and the structures made of wood and plastic you need to save a distance of at least 60 cm. But even then you can burn with an inadvertent touch. Therefore, the issue of isolation still remains relevant.

The easiest method of isolation in a similar case is the creation of a multi-layer sandwich design.

  • The chimney of the mustache is wrapped with mats from basalt nonsense wool, which are thinner than 50 mm. The melting point of this insulation is close to 1000˚, and this is much higher than smoke temperature.
  • On top of the heat insulation, the knitted steel wire is fixed and fixed.

  • Then the plaster on the above technology is applied using cement-limestone or clay-sandy solution.
  • Instead of plaster, you can use a casing of thin-leaf iron. The sheet must have a width of at least 1 m. The metal blank is folded over the diameter of the pipe with a layer of insulation and rushing along the line of the edge connection. Angles curl manually either use rolling rollers for this.

Buing a bath, you need to take care of the safety of your loved ones. The main danger is a live fire. If you do not perform high-quality isolation of chimney, stoves, ceiling and walls, then the overlap can catch fire. According to firefighters, for 2014, 70% of the balloons have occurred due to improper insulation of the pipe. We care about our readers and tell how to isolate the pipe in the bath with your own hands, what materials exist to protect against the fire design from the tree.

The tube in the bath should be safe and well to restrain the heat.

Chimney and stove quickly heat up. Traditionally, the baths are made out of the wood and they are easily ignited. For insulation of walls, ceiling, chimneys and stoves, a layer of clay, asbestos and other available materials was used in the old days. The main thing is that the material be a bad heat conductor and did not spare from high temperatures. Protect chimney not only for purposes fire safety. Condensate will not be formed inside the isolated design, the chimney will be slowed down and serves the owners longer.


Insulation of the furnace and pipes with the help of foil isolon.

Some people think that it is enough to cut the ceiling around the chimney with metal sheets, and the bath is completely isolated from the fire. The metal is heated in the same way, he will not save from fire. As the heat insulator for the chimney, it is also not suitable.

You can cut the pipe with red bricks, but not any bath provides for design and size similar design.

Modern manufacturers offer several variants of the material to insulate the chimney in the bath:

  • foloisol.

Let's focus briefly on each form.

Heat insulation for chimney insulation

Heat insole comparatively new Material. You can perform insulation with your own hands. Move from foamed polyethylene, which is hidden between two sheets of foil.


The heat insol is well withstanding high temperatures and is suitable for the bath pipe insulation.

Manufacturers offer heat source from 2 to 10 mm thick. The thicker material, the higher the temperature is withstanding. For easier presentation, consider the table:

The upper foil layer will protect the chimney from severe heating. Work with the material simply. It is wrapped around the chimney, fixing with a special metallized scotch or wire.

Folgoisol for protecting the chimney

Foloisol consists of two layers: foil and heat insulator. Foil plays a reflective role and retains 90% of heat in the bath. By environmental friendliness, the material is in the first place from the like, since the foil for manufacture is used thick food. The material is not afraid of ultraviolet and high temperatures from -65 to +175 ° C. It is a good insulator.


Foloisol has a coating of food foil, so it is harmless.

Often, folgic is covered not only the chimney, but also walls, ceiling steam. It is an excellent insulation, steam and waterproofer for a sauna or bath.

The sauna, trimmed in the philicia, resembles a thermos design. Heat does not leave, the bath quickly warms up and is cooling for a long time.

Sandwich Pipe - Find for Bath

Modern manufacturers are offered to install in a bath or sauna safe sandwich tube. By choosing a sandwich chimney, you can not worry about isolation. The chimney of several sections, which are easily inserted into each other. Collect design will be easily with your own hands. Sandwich tube for bath or sauna with iron stove.

Sandwich tube immediately has built-in isolation and insulation.

The design of the sandwich tube resembles a multilayer pie. From the inside a layer of stainless steel, then the insulation (basalt or mineral wool), Outside galvanized steel. The design is a modern method of built-in finished isolation of chimney. The design is intended to perform two functions at once: the soot does not accumulate inside, it does not overheat outside.

But iron stove To which the sandwich tube is essentially used in the sauna. What to do if you have traditionally russian sauna with brick stoveHow to perform isolation? Talk about it below.

How to isolate a pipe in a traditional Russian bath?

To build a pipe in a bath with a stone stove use a red brick. It is not afraid of high temperatures, it is holding warm long enough.

The design of the brick tube must be properly folded. From high-quality masonry will depend how much the design will last. Making a pipe for your bath, do not save, because repair work Can do it more expensive.

The pipe in the places of intersection with the roof, the ceiling and other parts of the roof design are used to isolate with metal sheets.

The output of the pipe on the ceiling and through the roof it is necessary to isolate from high temperatures with asbestos sheets. And the walls in the inside of the pipe are protected by metal galvanized sheets. You should not use simple iron sheets, as they are subject to corrosion. Around the pipe in places where it passes through the ceiling you can make a box and fall asleep inside the clay. It will further restrain heat and protect wooden overlaps From fire.

Properly isolate the pipe only half. It is also necessary to take care of the furnace, ceiling and bath walls.

Protective insulation furnace in the bath

Modern metal furnaces are simply installed on the foundation, with the posterior and side of the walls are cut by metal sheets. The stove made of metal with your own hands looks unsightly, it can be chosen by red bricks. It will be an additional insulator and will help keep warm in the bath.


Scheme of insulation furnace in the bath.

Previously, the stove was isolated asbestos sheets, but high temperatures It highlights harmful substances. Therefore, use asbestos in the steam room is not recommended.

Ecologularly isolate the stove with natural felt. The material is expensive, but is a good insulator. There will be no fire felt, and when I hit the spark, it will start to smooth. The smell is adjusted to be specific, not to notice so difficult.

When installing the furnace directly on the floor of the tree, we recommend paving the felt first in two layers, then make a brick pillow in three rows. Walls and floors around isolated with metal sheets with a height of 50-70 cm.

The correct insulation of the chimney or stove will extend the service life of the chimney and heat generator, and also lock wooden design From fire. And after reading the article will not arise, how to isolate the pipe in the bath.
