Do-it-yourself chimney from a profiled sheet. How to bypass the pipe on the roof with corrugated board? Sealing masonry pipes on the roof

Chimney lining can be made with any modern finishing materials. Their choice depends on what functions this design performs.

Today there are two types of chimneys:

• Operating.
• Decorative.

Let's take a closer look:

• The first design option can only be if the house has a fireplace or a stove (see Decorative lining of stoves: choice of material). It serves for normal ventilation so that the smoke freely escapes.
• A decorative chimney serves as a simple decoration of the building and does not carry any functional properties. For that and for that type of construction, similar finishing materials are used.

Advice. The operating chimney is constructed from refractory red brick, decorative - from drywall or other similar material.

Finishing materials for the chimney structure

Lining of chimneys above the roof can be carried out:

• Ceramic tiles.
• Decking.
• Plaster.
• Decorative or natural stone.

See photo of the chimney design.

Advice. When choosing a method for finishing chimneys, special attention should be paid to the properties and characteristics of materials.

Porcelain tiles for finishing the chimney

Such chimney tiling is performed both on the existing and on the decorative structure. Porcelain stoneware is the most suitable material for such a finish.
So:

• Forms of porcelain stoneware can be different. The sizes are also varied.
  There are very small tiles that have a parameter of 10x20 cm, and there are also large ones 90x60 cm, but they are not used in finishing work on the chimney.

The surface of ceramic granite tiles can be:

• Smooth and structural, embossed.
• Glossy, matte or glazed.

More:

• The material is made from several types of clays and feldspar, which provides high strength porcelain stoneware. The tile is subjected to double firing, which makes it more reliable and practical.
• During the first exposure to high temperature, the clay dough is hardened, and during the second, a decorative surface design and protective layers are applied.
• There is a wide range of porcelain tiles and due to this, you can create a unique design for any design.

The main properties of the material are:

• Moisture resistance, which makes it possible to use porcelain stoneware in any climatic and weather conditions.
• Its surface does not absorb dirt and is quite easy to clean. You can use any detergent for this.
• Fire resistance, since the material does not burn and does not deform under the influence of high temperatures. This technical indicator is especially important for existing chimneys (see Finishing the chimney outside and inside the house).
• Frost resistance, as it can withstand very low temperatures.
• Wear resistance and durability. Throughout the entire service life of ceramic tiles, it does not lose its external design and technical properties.

At the same time, the price of porcelain stoneware tiles is quite low, which makes the material even more popular. It is also worth considering that porcelain stoneware has a rather significant weight, which must be taken into account when choosing its masonry on the surface.

Installation of porcelain tiles

For lining chimneys with porcelain tiles, a concrete solution or a special adhesive is used, which is intended for use in outdoor finishing work.
You will also need:

• A tile cutter used to cut material.
• Building level for a more even finish of the chimney.
• Roulette and decorative putty.

Advice. It is worth considering that porcelain stoneware tiles can only be fixed on a flat surface.

The surface of the operating chimney must be leveled with asbestos cement mortar. After it dries, the surface is primed. The video shows the process of installing porcelain tiles.

Decking for finishing the chimney

Facing the chimney pipe with corrugated board began to be performed quite often. The surface of the material can be glossy and have a different design.
There are imitations of modern finishing products. As a rule, the surface of the corrugated board is covered with a polymer, which reliably protects it from weather and climatic conditions.
The corrugated board is made of stainless steel, which does not corrode under the influence of a humid environment.
Decking:

• Does not burn or melt.
• Waterproof and practical.
• Frost-resistant and wear-resistant.
• Withstands high and low temperatures.

Proper operation of the heater is possible only if there is a system for removing combustion products. But it involves the arrangement of a pipe passing through the ceiling and roof.

Moreover, the junction of the channel to the roof must be airtight, not have gaps, and to maintain the style of the building, it must be lined with the most suitable material.

The process of performing all these works or finishing the chimney must comply with fire safety rules, since the gases passing through it heat the structural elements to a temperature that can cause a fire.

What needs to be done during the installation of the chimney so that the equipment works efficiently and is safe for others?

The sealing of the chimney on the roof requires the following conditions:

The passage of the chimney can be made on a ridge or a roof slope, while each of the methods has its own characteristics.

The first option may lead to the need for a partial change in the rafter system, and the second one can become a pocket for snow. But these shortcomings can be easily solved by adding an element under the ridge bar, which will avoid leaks.

After the pipe passes through the roof, it is sealed. Market building materials offers a wide range of units that can be used in various conditions.

Of the traditional options, this is a salary of metal strips corresponding to the dimensions of the pipe.

For a roof made of tiles or a corrugated plate, the elements are fastened with a lying seam, and on pitched structures with a slope of more than 30 °. Behind the chimney, a special beam is installed. It serves as protection against rain water.

Waterproofing the chimney on the roof involves the arrangement of a protective apron. It can be made of flexible tape or metal coated with a polymer composition.

An elastic apron is installed along the perimeter of the pipe in two layers, leading the lower one under the roofing, and mounting the upper one from above and closing it with metal profiles.

Insulation from steel sheets is placed on the roofing insulated with roofing material. Its individual elements are attached along the perimeter of the channel, starting from the bottom. The grooves are filled with silicone or polymer sealant.

Chimney lining and materials for it

Finishing work on the exhaust gas system is carried out before the roof is laid, which avoids damage or contamination. There are enough cladding options to make the right choice. Usually, the finish on the roof of the chimney pipe depends on the material from which the structure itself is made.

It could be:

• Clinker tiles or bricks
• Plaster
• Fiber cement boards

Consider the features of each material. Clinker bricks are durable, resistant to temperature changes and atmospheric precipitation. As a facing material, only solid brick is used, the laying of which is carried out on a special mortar. To fill the seams, grout compositions are used.

Watch the video, what material to line the chimney:

Clinker tiles are light, thin, and have excellent aesthetic properties. It is used when facing high chimneys.

Plastering is a simple and cheap way of finishing, but with a limited service life. The screed is made of cement mortar, sometimes with the addition of lime. But such a lining on top should have a decorative layer, for example, made of silicone paint.

Small-format plates are one of the most durable and resistant to aggressive environment materials. They are attractive and non-flammable.

Finishing the pipe with slate: stages of work

Facing the chimney on the roof is necessary not only for better preservation of the chimney structure, but also as a decorative finish, so it is customary to make it from materials that are most suitable for roofing. One of the most durable, durable, and also very aesthetic is the stanets.

Its color depends on the deposit and can be:

• Purple
• Green
• Graphite

It can be in the form of tiles or panels. Slate can be fastened with copper nails with a wide head with a diameter of 2.5 mm and a length of 40 mm.

When performing work, it should be borne in mind that deformation of materials is possible during temperature changes. Therefore, the nails are not nailed to the end; a small gap must be left between the cap and the tile.

The installation of tiles is carried out on the crate, the bars are fixed at the corners of the chimney, and if it is more than 60 cm wide, one more additional bar will be required.

Finishing the chimney on the roof is carried out in several stages:

1. The extreme guides are set according to their level, the rope is pulled (from above, below and in the middle - at a height of more than 2 m), and then intermediate bars are set
2. If necessary, the smoke channel is insulated
3. Plywood sheets are laid on the guides
4. Tiles are being laid (its installation is carried out in such a way that one overlaps the other within 1.2, and the angle is not less than 22 °

There are several ways to lay slate - from the standard rectangular to resembling fish scales. They are selected taking into account the pattern of the roofing.

Chimney plaster

The simplest and cheapest way of facing is to cover the surface of the smoke channel with a cement composition. But such a lining has an unpresentable appearance and, moreover, is short-lived. Therefore, it is recommended to apply marble or Venetian plaster on top of it.

The first is performed on a pre-primed surface. To do this, the dry mixture is diluted in a bucket with water in the proportions indicated on the package. Please note that it is usually sold in white, and color is added to obtain a color coating.

The diluted composition is applied in a thin layer and left to dry, and then cleaned with a steel brush. Then a second layer is applied - if necessary, but experts still recommend limiting themselves to one. The final touch is surface treatment with a grinder and grouting with an iron spatula.

Venetian plaster, unlike marble, is considered expensive, but it looks amazing. Moreover, if you do everything yourself, you can save a certain amount of money.

It is also sold in bags, has a white color and is diluted with water with the addition of color for application. Apply with a spatula or trowel. But to obtain a high-quality coating of Venetian plaster, the use of forced drying technology with a building dryer is required. The cracks that appear are treated with paint or varnish and, after drying, polished with a grinder.

Wild stone as a facing material

Another option for finishing the chimney can be the use of natural materials. In this role, a wild stone has proven itself well. It is laid on cement using a plaster mesh fixed to the surface for adhesion rigidity. The seams are sealed with cement with the addition of color to it.

And last step work related to the arrangement of the exhaust gas system is the finishing of the chimney inside the house. It can be made of various materials, the choice of which depends on the interior of the room.

The importance of chimney trim

In this article, we looked at the assembly, insulation, and cladding of a combustion exhaust system. Each of these stages is mandatory for the efficient operation of heating equipment, but can be performed using various materials. Which one is the best is up to you. After all, it depends both on the design features of the chimney and on the architectural style of the entire building.

Roof pipe

According to professionals, the exit of the pipe through the roof is best done through the ridge, since in this place it is perhaps the easiest to arrange the junction of the roofing to the pipe, and also thanks to this it is possible to avoid the formation of snow pockets and, therefore, reduce the likelihood of leaks to a minimum .

However, the downside to this case is the need to create a roof truss system without a load-bearing ridge beam, or to break the beam at the place where the chimney passes with the installation of additional supports at the break points.

Another nuance is that for round pipes, manufacturers, as a rule, do not produce components with which it would be possible to pass the pipe through the roof.

Therefore, we are talking only about chimney pipes of rectangular and square sections.

Another successful method of positioning the relative roof pipe is its placement near the ridge, on the slope, which will also avoid the formation of a snow bag and, from a technical point of view, will be relatively easy to implement.

Pipe height above roof

The height of the pipe above the roof, depending on its location

The pipe through the roof should not be mounted, where the valleys are located - the junction of two slopes that form an internal corner.

It is very difficult to achieve a high-quality adjoining of the coating to the pipe here, while an additional load on the chimney (including from the point of view of its sealing) will be created by the water flow collected from the adjacent slopes, and in winter an extensive snow pocket will form above it

Roof pipe sealing

As a rule, the process of sealing the joint between the pipe body and the roof plane is carried out using ready-made kits purchased together with the roofing material. Moreover, one set is used for square chimneys, and a completely different one for round pipes.

The roof joint and the pipe are sealed using a special part - an apron, spherical or rectangular in shape. Such an apron is worn over the pipe in such a way that its edges extend beyond the boundaries of the box in which the chimney was mounted. Moreover, an apron is simply overlapped on the roofing material, and it is attached to the pipe with self-tapping screws. The joint between the pipe and the apron is sealed with a heat-resistant sealant.

The sealing of round chimney pipes can be implemented using an apron-cap worn over the pipe. The conical protrusion of the cap, at the same time, is cut to the desired diameter.

The process of sealing the top of the pipe, in a simplified form, is as follows:

• At the very beginning, the remnants of the roofing material that cover the box are removed.
• Next, a layer of elastic waterproofing is glued to the edge of the roof.
• An apron is mounted on top of the waterproofing layer, the lower edge of which is laid on the roof, and the upper edge on the pipe.
• The points of contact between the apron and the roof are fixed on self-tapping screws with wide rounded “hats” (roofing option).
• The apron is fixed to the pipe with an elastic sealant. After that, the joint of the apron pipe is pressed with a clamp.

Types of chimneys

Chimneys according to the material from which they are built are divided into brick, metal, asbestos-cement, pipes - sandwiches and modular.

At the place of installation, chimneys are:

• Wall - when the pipe is located in the main wall of the building, internal or external; mounted, when the pipe is installed directly on the furnace;
• Suspended - the chimney is attached to the outer wall of the building;
• Indigenous - when the chimney looks like a free-standing structure next to the stove

Types of chimneys and requirements for them

In order for the chimney to reliably remove flue gases, provide draft and at the same time be fireproof, it must meet certain requirements.

Chimney height. It is believed that the higher the pipe, the better the traction. On the one hand, this statement is correct, but has certain limitations. Passing through the pipe, the gases are cooled, and the higher the pipe, the stronger. And this, in turn, leads to a decrease in traction, smoke and the appearance of condensate on the inner walls of the pipe. It accumulates and flows into the furnace.

Cross section of a chimney. In addition to the height of the chimney, there is another important parameter - the size of the section. It must correspond to the power of the firebox: the larger it is, the greater the clearance in the pipe. Reducing the cross section leads to the fact that the flue gases do not have time to be removed from the furnace and it begins to smoke. If the clearance is too high, the flue gases begin to move slowly and cool down. This also leads to a decrease in traction and the appearance of condensate.

Heat dissipation of the chimney. The increased heat transfer of the pipe also leads to the same result. Only here for a different reason: not by reducing the speed of smoke, but because of its rapid cooling.

Heat resistance of the chimney. When choosing a pipe, its heat resistance plays an important role. despite the fact that the temperature of the exhaust gases is usually below 300 degrees, the internal surfaces of the pipe must withstand higher temperatures - up to 500 degrees for a long time and up to 1000 degrees for 30 minutes. The last requirement is related to the possibility of ignition of soot in the chimney, the combustion of which takes place at a high temperature. Outside, the pipe should not heat up above 90 degrees, and at the junction with combustible structures - above 65 degrees.

Mechanical strength of the chimney. Chimneys must be made of materials that provide high mechanical strength. For example, in case of fire, the pipe must maintain structural rigidity for 90 minutes. The inner surface of the pipe must be chemical resistant. Since flue gases and condensate have properties with increased chemical activity and can destroy the pipe from the inside. And from the part of the pipe that rises on the roof of the house, frost resistance is also required.

brick pipes

Properly built from high-quality ceramic bricks, pipes usually meet all the requirements listed above and are distinguished by solidity and durability. The disadvantages of such pipes include the complexity of their construction and heavy weight.

But the widespread construction of closed fireplaces in country houses led to some changes in the requirements for brick pipes. The fact is that the flue gases coming out of the fireplace insert have a temperature of 400 degrees (in traditional brick ovens - 250 degrees). Therefore, it is recommended to build a chimney from a special ceramic brick, horizontal seams should be no more than 5 mm thick, and the pipe walls should be 250 mm (at 120 mm, the pipe warms up to 150 degrees, which is unacceptable). Following these requirements significantly increases the cost of the pipe and its weight.

Asbestos-cement pipes

AT cottage construction, in the construction of small houses, baths and summer kitchens, asbestos-cement pipes have long been used. They are cheap, lighter than brick and quickly mounted. However, sometimes when heated too much, they crack, which can lead to a fire. Usually the outer surface of such pipes is very hot.

Steel pipes

Steel pipes are usually used for stoves, sauna stoves, gas boilers. The main disadvantage of these pipes is that they burn out in a short time. The smoke in them, as in asbestos-cement pipes, cools quickly and at the same time causes abundant condensate. And the high surface temperature of a metal pipe makes it a fire hazard. From the point of view of modern requirements, single-layer steel pipes are unacceptable. They must be enclosed in an additional fireproof shell (steel can be used).

Modern types of pipes

Basically, modern chimneys are assembled from prefabricated elements or sections made in the factory. The task of the stove maker is reduced only to the connection of these sections. Such pipes are well insulated, fireproof, acid-resistant and adapted for the removal of low temperature smoke.

The most widespread are the so-called sandwiches - chimneys, consisting of three layers: an inner one made of stainless steel, a middle one - a heater, and an outer casing made of galvanized iron or stainless steel. the pipe is assembled from sections about a meter long. At the same time, the sections come in different diameters, which makes it easy to choose the pipe necessary for the furnace.

The advantages of sandwiches are ease of installation and low weight. They do not require a separate foundation, which reduces the cost of pipe installation. But, as far as I know, the price of the sandwich elements themselves is still quite high and, in general, such a pipe will cost more than the same brick pipe of equal height. In addition, when heated and cooled, the individual elements of the sandwich can move relative to each other, which leads to loss of tightness of the entire system and the occurrence of fire hazards. The shelf life of such pipes is about 10 years.

Modular pipes assembled from ready-made factory elements are gaining more and more popularity in furnace construction. These are multilayer structures consisting of a refractory inner core (stainless steel or fireclay pipes), basalt insulation and a durable body made of lightweight concrete. Such chimneys have increased fire resistance, chemical resistance and rigidity. The external temperature of the pipe with intensive fire is only 40-60 degrees, which allows you to use any materials for finishing pipes. Such pipes can adjoin combustible structures.

Chimneys are easy to install both inside the house and outside. The cost of modular pipes is comparable to the cost of a steel three-layer chimney. Service life - up to 30 years. A running meter of such a pipe weighs about 120 kg (a brick meter is 2-3 times heavier).

Chimney pipe lining: material characteristics

The chimney is finished before laying the roofing material, which avoids possible damage or contamination of the coating and greatly facilitates the work.

There are many options for lining the chimney and choose it depending on the type of material used to make the chimney.

A fairly practical solution is the use of clinker tiles or bricks. Dirt is not visible on them, they are in good harmony with any type of roofing.

Clinker bricks are distinguished by their strength and resistance to sudden temperature changes and the aggressive influence of the atmosphere. When facing, only full-bodied bricks are used. It is placed on a special masonry mortar, and the seams are filled with special grouting compounds.

Clinker tiles are lighter and thinner than bricks, but they look just as good.

Clinker tiles are more suitable for lining very high chimneys.

The chimney can also be finished with plaster. This is a relatively easy and affordable way to finish the chimney with plaster, but, unfortunately, not particularly durable. For finishing work, a screed made of cement or lime-cement mortar is used. To increase the endurance of the finish, respectively, and its service life, the screed is coated with, say, silicone paint.

Mineral, acrylic, silicate and silicone types of plaster are considered stronger than traditional ones.

Small-format fibre-cement boards are durable, resistant to moisture, UV radiation and sudden changes in temperature. They are non-combustible and environmentally friendly, outwardly quite attractive. Plates have a wide range of colors and light weight. Their surface is absolutely smooth or structured.

slate roofing The chimney and roof are also lined with an extremely strong and durable natural material - slate. Depending on the deposit, shale is purple, green or graphite in color. Plates of this material have a different shape - a rectangle, an arc, a scale, an octagon.

Chimney lining inside the house

The choice of material for lining the chimney inside the house largely depends on the style of the room. You can lay it out of clinker bricks, fit it into a brutal interior without additional decoration.

The most ancient way of finishing is plastering. Suitable for interior in the style of "village hut". The chimney can be whitewashed or painted with heat-resistant acrylic paint.

Facing the fireplace and chimney with refractory tiles, tiles, majolica tiles, clinker tiles or natural stone will help decorate any interior, since the modern market is rich in a variety of materials. The choice depends on the style, financial capabilities and taste preferences.

The main thing to remember is that the finish must be safe for the life and health of people living in the house.

Rooftop chimney trim

Around the chimney along its entire perimeter, at the point where the pipe exits to the roof, a two-layer protective apron is arranged. The first layer is placed under the roofing, the second is placed on top of the roofing.

Such an apron is called a salary or collar, made of metal (galvanized or steel sheet). Currently, ready-made salaries can be purchased on the construction market. The places where the apron adjoins the pipe must be sealed.

The need for additional finishing of the chimney on the roof is determined by the following factors:

• pipe laying is made of low-quality material (brick);
• there is no traction, it is necessary to perform additional insulation of the pipe;
• the appearance of the pipe does not match the appearance of the house; decoration is required.

How to close the chimney? Any material must be resistant to precipitation and any influences (wind, sun, temperature difference).

Under any pipe lining, it is necessary to make a frame for attaching the finishing material. The frame is made of antiseptic timber or metal guides. The chimney lining is arranged only on a metal frame.

The lining of the chimney and ventilation pipes on the roof can be galvanized metal coated with a polymer. In appearance, it can be smooth or profiled (profiled). This is perhaps the most inexpensive finishing option.

The most practical solution is a chimney made of clinker bricks. But you can simply line the pipe with clinker tiles, which are combined with many roofing materials.

Finishing the chimney with artificial or natural stone, which is also used in facade decoration.

The material of the finishing material must be non-combustible; lime-cement plaster can be used as a finish. In this case, the plastered pipes will be combined with the plastered facades, the building will look solid.

Double-walled (double-circuit) sandwich pipes are also applicable for chimneys. You can read about this in a separate article dedicated to this topic.

The chimney can be lined with cement-fiber boards. This non-combustible material has an attractive appearance, is available in various colors.

The use of siding is suitable only for lining ventilation ducts facing the roof.

The choice of material here is much wider, up to the roofing material used for roofing (metal tiles, soft roofing).

However, a lined chimney of a completely unconventional shape can become the main decoration of the house.

Types and installation of chimneys in a private house

Such a chimney does not require additional finishing.

Where is the best place on the roof to place the pipe

The higher the better. The ideal place is the ridge, the highest point. Firstly, traction is maximum, and secondly, waterproofing is simpler and more reliable. You also need to consider that the farther from the ridge the chimney is located, the higher it should be. This does not paint the roof and complicates its construction. The roof of the masterpiece of the Renaissance, the castle of Chambord on the Loire is crowned with many chimneys of a very intricate shape. Now they don’t even know how to do this in France.

Chimneys are easily exposed to various negative influences. It can be temperature fluctuations or aggressive weather conditions. During combustion, the condensate formed in the chimney destroys it. And the formation of condensate is caused by the temperature difference between the operating pipe and the air. Various impurities formed in the chimney lead to its destruction. To avoid such moments, it is necessary to carry out the insulation of the chimney with the help of lining. How to sheathe the chimney with corrugated board or other material, which option is cheaper and which is more reliable, what is the chimney lining made of?

Decking is a coating that can be used in the construction of buildings.

You will find answers to all these questions by reading the article to the end.

The choice of facing material

The chimney, or rather, its part protruding above the roof, is most exposed to negative environmental influences. Another important point is the aesthetic side of the chimney, as this element is quite catchy, and, in addition to technical conditions, must match the style and color scheme of your home. Simply put, the chimney should not spoil the appearance of the roof, but contribute to its decoration.

The lining of the protruding part of the chimney involves the use of various materials. The main thing is that they are resistant to the effects of precipitation, wind, low temperatures, ultraviolet radiation and temperature extremes. It meets almost all of these qualities. Not the last factor when choosing is the appearance and color range of the material intended for facing work. The chimney should look harmonious with the roof covering and match the style of the whole house. The chimney, that is, its lining, is performed before the roofing material is laid. In this case, you will not damage the roof and avoid contamination of the roof surface.

Chimney. Facing methods

The lining of the chimney, or rather, its methods, are quite diverse. The choice depends on what material you have chosen for the chimney device.

P-20 professional flooring is the most popular and universal profile.

Quite a practical way is the use of clinker bricks or tiles. On a chimney lined with such material, dirt will not be noticeable. Another advantage of its use is the absolute combination with any roofing. The positive properties of clinker bricks include strength, resistance to temperature extremes and weather conditions. Only full-bodied clinker bricks laid on a special clinker mortar are used.

Another way with which you can veneer the chimney is plaster. Its advantages include a fairly low price, lightness, durability and versatility. Pipes are plastered in the same way as facade walls are plastered. To increase the durability and wear resistance of such a cladding, you can apply silicone paint over the plaster.

As another option, the lining of the chimney pipe is used with the help of a ready-made structure. It is produced in the factory and is part of a chimney pipe equipped with a steel channel. Such structures can be lined with brick or other material, painted, plastered or reinforced with mesh (for subsequent plastering). The appearance of such structures is quite effective. The cladding is made of the same material as the roofing. It can be cement-fiber boards, profile sheet (cladding with corrugated board), slate and so on. All these materials look quite aesthetically pleasing and practical in their application.

Cladding with corrugated board. Advantages of using a profile sheet

The profile sheet is considered one of the most popular in modern construction.

Another name for it is corrugated board. Scopes of a profile leaf are various enough. The most popular areas are the construction of walls, the manufacture of fences, roofing and, of course, use as a material for cladding. The advantages of profile flooring include such qualities as:

• quick and easy installation;
• easy maintenance;
• durability;
• low cost;
• light weight;
• resistance to high temperatures.

There are a large number of varieties of profile sheet. Here is a short list of the main types:

Installation of the profiled sheet is carried out in one direction: from corner to corner.

• combined type profile sheet (used in various designs);
• galvanized profile sheet (used as a roofing material);
• painted profile sheet (to cover roofs and other structures);
• aluminum profile sheet (possesses the properties of durability and high resistance to a humid environment);
• profile sheet of the supporting type (possesses the qualities of increased strength, can withstand heavy weight);
• roofing profile sheet (used for roofing, as well as a facing material);
• a profile sheet of a facing type (to protect various structures from negative impacts, including a chimney).

A profile sheet in modern construction is a fairly demanded material for cladding. It is a steel sheet of a profile nature, produced from galvanized steel (galvanized profile sheet) or from steel with a polymer coating.

Cladding with corrugated board gives the structure a complete look. Such qualities of a profile sheet as incombustibility, environmental friendliness, reliability, durability, resistance to mechanical stress make it indispensable when lining a chimney pipe.

The nuances of performing installation work with corrugated board

Advantages of a professional flooring: ease of installation, durability, quality of production.

Before carrying out installation work with corrugated board, it is necessary to comply with the conditions for its storage. The room in which the profile sheet is stored must be dry and well ventilated. The profiled sheet must be stored in a horizontal position on a plane. If it is impossible to store indoors, the profile sheet is covered with a film with waterproof properties, since moisture ingress is undesirable.

To cut a profile sheet, you will need a circular saw in which a special blade is fixed, or an electric jigsaw. It is considered undesirable to use a grinder for, since when heated, the sheet coating (polymer or zinc) is damaged. Before performing the installation of profile sheets, it is necessary to study their geometry.

If there are any errors, then they will need to be corrected during the installation process using additional components. Parts of the sheets along the bottom edge should form a single line. You will also need construction gloves or mittens to protect your hands. When installing a profiled sheet, the strength of the manufactured structure is very important, since strong gusts of wind can disrupt the cladding elements. Self-tapping screws are used to connect the profile sheets to each other. Accuracy when joining sheets is a guarantee of an aesthetic appearance.

Knowing the features and nuances of the upcoming installation, you will avoid unforeseen situations during work. Good luck building!

A chimney is necessary in any house where a heating boiler or stove is installed, even after installing a boiler, it will be necessary to resolve the issue of removing combustion products. In addition, there are decorative chimneys that do not have any functional properties, but are an important element in the design of the roof. Chimney decorative finishes can be made using a wide variety of materials, and the choice is constantly expanding.

Options and features of exterior finishes

Finishing the chimney on the roof performs a decorative role. To avoid maximum smoke removal and prevent the formation of condensate, the outer part of the pipe must be insulated, and insulation materials need mandatory external protection. The finish of the chimney pipe should be in harmony with the design of the roof, and it will make the smoke exhaust structure a full-fledged decorative element.

!!! Important. It is strictly forbidden to use as a chimney pipe asbestos pipes or asbestos cement!

There are a lot of finishing options, we can name the most relevant of them:

Finishing the chimney with a metal profile from the outside

Finishing the chimney on the roof with corrugated board is one of the simple options, even a novice home master will cope with such work. A galvanized sheet provided with an anti-corrosion coating will become a strong and durable solution: it does not burn, does not collapse under the influence of high temperature or strong vibrations, and the installation of such a cladding does not take much time. However, this is a cold material, so the chimney will have to be insulated.

Finishing the chimney with a metal profile is carried out after construction metal frame. Metal sheets are overlapped on it to ensure the most durable connection. To ensure that the sheets are evenly positioned, a building level is used when attaching them.

The metal profile is attached with self-tapping screws; this work is more convenient to carry out with a screwdriver. Between the metal sheet and the chimney there is a layer of non-combustible insulation.

Finishing the chimney inside the building

A fireplace or stove is usually mounted in a living room or study, so it becomes necessary to draw smoke paths through the second floor and the attic or attic room. Finishing the chimney inside the house can be very diverse in appearance, but in any case, it is installed on a common basis. The interior of the chimney is carried out as follows:

1. For lining the chimney, a metal profile frame is constructed around it, which is sheathed with special plasterboard sheets. They must be fire resistant, this will ensure the fire safety of the house. Such sheets are designated by the special abbreviation GKLO.
2. The frame is insulated: a layer of mineral wool or other non-combustible insulation materials is laid around the chimney.
3. Smooth plasterboard sheets are finished with any selected materials: it can be ordinary wallpaper, ceramic tile, plaster and much more. This finish of the fireplace chimney allows you to harmoniously integrate it into the space of the room, and the choice of material depends on the style of interior design.

The interior trim of the chimneys can have a wide variety of colors, so you can choose it for every taste. However, in any case, it is recommended to choose non-flammable materials so as not to increase the risk of fire. This is especially important in a wooden house: the walls located near the chimney, and especially all sections of the bend, must be treated with flame retardants.

External and internal finishing of the chimney will turn it into a full-fledged decorative element: the choice of materials depends on the design features of the building and on the financial capabilities of the owner. Self installation cladding will save a lot, but it must be carried out with strict observance of all technological requirements.

The stove is folded, and the chimney proudly rises above the roof of the house. Do you think the work is done? Not at all - it's time to think about how to insulate the chimney pipe and protect the house from fire, and the roof from leaks. Well, if you thought about this issue even in the process of designing the furnace - in this case, the insulation of the chimney will be reliable and safe. It is more difficult to isolate an already built chimney, sometimes this work entails a change in the design of floors and roofs. However, the costs will be compensated by a sense of security and comfort.

It is necessary to isolate the chimney from two negative destructive factors: from overheating of the structures and from leakage at the joints. Therefore, in the article we will consider two types of chimney insulation:

• Fireproof thermal insulation;
• Waterproofing.

It is recommended to immediately carry out complex insulation, solving not only the main problems, but also improving the operating conditions of the furnace. For example, insulating a pipe running through an unheated attic reduces the risk of overheating wood roofing and reduces the risk of condensation, which can lead to excessive soot deposits, corrosion, or pipe failure. Waterproofing the pipe will help to avoid rotting of the truss system and ceilings, as well as the destruction of the pipe if it gets wet.

Ways of fire insulation of chimneys

The easiest and most reliable, but not always the cheapest way is to install a ceramic or metal sandwich chimney. In such chimneys, the inner pipe, which performs the function of removing smoke, is made of heat-resistant steel or ceramic and is thermally insulated with non-combustible heaters: mineral, stone or basalt wool. The outer layer of the sandwich chimney is made of steel or ready-made expanded clay concrete blocks.

Prefabricated ceramic chimney - a safe solution to the problem

Prefabricated chimneys are equipped with elements for fastening, revision, maintenance, as well as for connecting several heaters. Installation of such a chimney is not difficult, but requires compliance with the instructions, only then it will be completely safe.

Another insulation method used in the construction of the furnace is a brick chimney. Due to the low thermal conductivity of the brick, its walls do not heat up to dangerously high temperatures, so no additional measures to insulate such a chimney are required, except for the correct implementation of fire-prevention cutting of floors and roofs. To save money and facilitate construction, a brick chimney is sometimes finished with a metal or ceramic pipe. In this case, they are thermally insulated according to the technology described below.

Thermal insulation of metal and ceramic single pipes is possible using ducts made of non-combustible materials and mineral non-combustible thermal insulation - stone or basalt wool. It is possible to operate such chimneys without thermal insulation, but the implementation of fire cutting according to all the rules is mandatory in any case.

Methods for waterproofing chimneys

Chimney waterproofing is installed at the point of its exit to the roof. The larger the pipe and the farther from the ridge it is located, the more difficult operating conditions await it: when it rains, more abundant water flows, in winter - increased snow load. Rain and melt water with insufficient waterproofing penetrates inside the house, leading to leaks, rotting of wood and destruction of concrete and brick structures, including the chimney itself.

The method of waterproofing depends largely on the shape of the pipe and the type of roofing. For round pipes, metal or polymer grooves are used, for rectangular pipes, metal aprons and junction strips are used. How to waterproof the pipe is described in detail in the article, and then we will talk about the technology of thermal insulation of the chimney.

Chimney pipe insulation

Before proceeding with the insulation of the chimney pipe, it is necessary to check compliance with the requirements of SNiP 2.04.05-91 and, if necessary, correct the shortcomings:

• The height of the pipe to ensure good draft and allowable flue gas temperature at the outlet should be 5 meters or more;
• If the roofing refers to combustible materials - slate, ondulin, roofing material - a spark arrestor - a fine-meshed metal mesh - must be placed on top of the pipe;
• The distance between the chimney pipe and combustible structures - floors, walls, truss system - must be at least 250 mm;
• A fire-prevention distance must be maintained between the upper ceiling of the furnace and the ceiling. For metal furnaces it is at least 1.5 meters, for brick with a two-row overlap - 0.5 meters, with a three-row overlap - 0.25 meters, provided that the ceiling above the stove is finished with non-combustible materials;
• In places where a brick chimney passes through the ceiling, fluffing is performed - thickening the pipe. Fluff thickness - 1-1.5 bricks.

Plastering a brick pipe

The brick pipe does not heat up much from the outside, so it must be insulated as soon as possible in order to improve operating conditions and extend the service life. The most affordable way to insulate a brick chimney is to plaster with cement mortar or a mortar based on cement and lime. Instead of sand, you can add sifted slag chips to it.

The composition of the solution:

• 1 bag of cement (25 kg);
• 2 buckets of slaked lime;
• 10 buckets of sand or a mixture of sand with slag chips;
• 5 buckets of water.

1. To prepare the solution, 3.5-4 buckets of water are mixed with a bag of cement and 2 buckets of slaked lime - fluff. After thorough mixing, sand and slag chips are added in parts, as well as the remaining rate of water. The resulting composition should be used in cool weather for 5 hours, and in hot weather - for 1-2 hours, so you can cook it in parts.
2. With large irregularities in the pipe, the plaster layer turns out to be quite thick, so it is recommended that you first close up all the cracks and differences with the indicated solution, and then wrap the pipe with a reinforcing mesh.
3. Plastering is carried out in two layers. For the first layer, the solution is diluted somewhat stronger, to a creamy state, and applied by spraying: a certain amount of mortar is taken on a trowel or spatula and sprinkled on a brick surface cleaned of dust and slightly moistened. The first layer is not leveled.
4. For the second layer, a thicker solution is needed. It is applied with a trowel and rubbed to a smooth surface. It is necessary to plaster the entire pipe from the floor to the ceiling or roof.

Sheathing of brick pipes with asbestos-cement sheets

This method exceeds plastering in terms of heat saving by 2-2.5 times and consists in gluing asbestos-cement boards on cement-lime mortar on the outer walls of the pipe.

1. According to the above technology, a plastering solution is prepared.
2. The pipe is reinforced with mesh and the first layer of mortar is sprayed on. Dry it up.
3. Cut asbestos-cement sheets to the size of the pipe. A second layer of mortar is applied to asbestos cement sheets and glued to the surface of the chimney.

The disadvantages of this method include the low environmental friendliness of asbestos - it releases carcinogens, so it is impossible to use this method of isolation in living rooms. In a non-residential attic, thermal insulation of the chimney with asbestos will reduce the temperature difference between the inside and outside of the chimney and significantly reduce the formation of condensate, as well as improve its fire protection.

In addition, a brick pipe can be sewn up with sheet iron using a layer of insulation. How to do this, you can learn from the video.

Insulation of metal single pipes

The most dangerous version of the chimney in terms of fire protection is a metal pipe that is not protected by a heat insulator. The distance from such pipes to wooden and plastic structures should not be less than 0.6 meters. But even observing this distance will not protect you from burns if accidentally touched, so it is better to insulate the pipe without waiting for problems.

Uninsulated metal pipe - common cause fires

The easiest way to insulate a single pipe is to wrap it with a layer of non-combustible insulation, such as basalt wool, and protect it from above with metal or plaster. The melting point of this material approaches 1000 degrees, which is much higher than the temperature of the smoke.

1. Basalt wool mats with a thickness of at least 5 cm are wrapped around the pipe with an overlap and fastened by wrapping steel wire over it.
2. They wrap the heat-insulated pipe with a reinforcing mesh, fix it, and plaster it according to the technology described above in two layers with a cement-lime composition.
3. Plaster can be replaced with thin sheet iron by rolling it along the diameter of the insulated pipe and riveting it at the junction of the edges.

Insulation of passages through floors and roofs

The most critical sections of the chimney insulation are passages through the floors, so they are given special attention. It is obligatory to isolate the passages when using any chimney: both a sandwich pipe, and brick, and metal in isolation.

Passes are carried out subject to the following conditions:

• In the ceilings and roof, holes are made for the passage of the pipe in such a way that there is a distance of at least 25-35 cm from its edges to the walls of the pipe.
• The edges of the hole are treated with asbestos-cement or metal sheets, and a box is arranged for thermal insulation.
• The space around the pipe is filled with stone or basalt wool without the formation of voids and gaps.
• Wooden structures located in the immediate vicinity of the chimney passages are treated with flame retardant compounds.

Insulation of passages through floors with basalt wool

Having figured out how to insulate the chimney pipe, you can easily do this work, but remember that even an insulated chimney pipe requires proper operation: clean soot at least three times a year, remove ash from the furnace in a timely manner, do not burn in it not intended for the firebox materials and objects (garbage). All this is the key to a long and safe service of the chimney.
