How to Build Brick Chimney

In winter, there is nothing more enjoyable than enjoying a good fire around the fireplace and as I am from town and I love the warmth of the fireplace we have decided to make one in the cottage.

As the house is very small inside, the chimney we will guide it all to the outside of the house, so that the interior does not occupy anything and even in the summer-spring season, when not used can be hidden.

Well, as I mentioned both the hood and the smoke pipe I have built them from the outside. We started raising the desired measures for the chimney which at first are 80 centimeters deep by 100 centimeters but then with the inner lining of refractory bricks these measures will be reduced.

Iron rods are placed on the base where the walls will be mounted to reinforce the start, although the base is already concrete and is a stable surface.

For the first row, bricks of different sizes are used to save the unevenness of the concrete floor.

Now we have the base level and it is easier to go placing the next rows of bricks. I have used bricks 7 centimeters thick forming a double wall with a small air chamber to avoid, as much as possible, the loss of heat and since the budget I have is not very high and I cannot use special materials too expensive.

We reach the desired height with the first brick wall, then the smoke pipe will take a pyramidal shape to the headboard or chimney cap.

The first brick wall is cemented to make it stronger, faster and cover possible holes.

The air chamber remaining between the two walls can be filled with expanded clay, for example, to increase the insulation.

The opening of the chimney is proceeded from the inside, so the debris will fall directly to the base and serve as a fill to increase to reach the desired level.

The area of ​​the fireplace that houses the fire is called “home”, is one of the fundamental parts of the chimney and therefore is very important the choice of materials to be made. In this case I have chosen refractory brick. It can also be; Refractory ceramics, cast iron or steel sheet. After we have paved the rubble we have covered them with dry gravel and then we have added another layer of concrete.

The mission of the bard 1 is to prevent the direct descent of the cold air, which weighs more than the hot one and therefore goes down and could produce smoke plasters into the interior of the house, which is why the bard 2 must of being below 1 and to the same perpendicular vertically speaking so that the cold air does not go down directly. In this way the cold air, let’s say it is entertaining and leaves the warm air that is produced in the “home” that goes up through the smoke ducts. To make this design I have based on the fireplace that I have at home that has a very similar system. I will try to put a video when I turn it on for the first time to see how the fumes come out.

The interior walls are covered with refractory brick 3 centimeters thick.

Once finished outside the “home” we are preparing to build what will be the chimney which in turn does the function of the smoke ducts, since the chimney does not have any metal tube to expel the fumes.

While in the interior, we are covering and finishing the edges of the walls with refractory brick.

Also in the fire zone are placed the refractory bricks.

Top between the fire zone and the front that is slightly higher than the inside.

Before plugging the chimney with the chimney, we will put insulating material on top of the bards to better withstand the heat, then proceed to cover the cork with a good layer of plaster so that there is no danger of burning.

We go with the elaboration of the bell. At the top of the roof we have helped two rods to place the wire, which will guide us, at the appropriate distance, that is, in order to leave, in this case, a smoke outlet of 30×30 centimeters more or less.

In the image you can get to appreciate the wires as they will help to form the bell in pyramidal form.

While the inside is already practically finished.

When it is completely in line with the wall, the chimney is a bit bland, as it does not have the typical wood over it nor some pillars on the sides. So we decided to decorate it a bit by placing a cement frame around it.

The desired contour is marked with a pencil and then the paint is bitten so that the cement grabs the wall.

It is filled with cement (a thickness of about 2 centimeters) around the contour, or to the eye, or we can help with slats of the desired thickness as a guide.

In the image you can see the thickness of the layer of cement applied to make the frame of the chimney.

If you do not like it to be just a straight line frame, you can help with some tool such as a knife, spoon, etc. to mold the cement.

In this case I carry a tool that is used in the plaster.

You have to work the cement when it is firm but before it completely shrinks.

This is the way more or less, failing to clean the remains of cement and re-paint the parts that previously had cement.

While, on the outside, we continue with the construction of the bell and placing the bricks with the proper inclination marked by the wires and the wall guides.

As I go up the rows of brick I am wearing plaster on the inside of the bell. Gypsum withstands heat better than cement.

I had to break part of the roof to continue with the chimney. Normally it is recommended that the chimney overhang the roof, as long as they are reasonable measures.

We have finished with the bell, it is time to start with the cap, cap or headboard, whose purpose is to facilitate the exit of fumes and prevent rainwater from entering. I have cut 110mm diameter pvc tubes and filled them with concrete to be used as pillars of this mini-roof. As a base I have used two pieces of porcelain left over from a friend.

Slopes are formed to place the slanted tile with a blown brick to prevent water from soaking the walls of the headboard.

The tiles are distributed and placed seated in cement they do not move .

This is the finished interior and a side view of the fireplace in which you can appreciate that it does not occupy space inside the dwelling.

Here are the photos of the bards from within. One of the bards is superimposed on the bards that start from the fire zone, maintaining a hole 10cm high by 90cm long for the smoke to rise upwards.

How to build an outdoor fireplace, step by step

Now that the cold seasons begin many of us start dreaming of chimneys, which serve to warm up, to create atmosphere, to cook … there is no doubt that both inside and outside the houses, chimneys are an important part of the homes that can afford them. There are chimneys that are bought ready-made and installed, but we can also make them by ourselves, especially outdoor ones.

An outdoor fireplace is ideal to enjoy more of the patio or the garden during the fall and winter, as it provides the necessary warmth to make the fresh atmosphere more pleasant. The construction of a chimney not as complicated as it may seem at first glance, is simple and can be done by following some basic rules, we will see how to build a simple fireplace in a few steps .

  1. The first thing is to choose the place where we want to place the fireplace, it must be away from things that can burn, cables and pipes, in the fireplace we are going to make fire, we must be very aware of this and always avoid the risk of fire.
  2. Once the place has been chosen, we clean it and mark the area, we can paint with chalk, for example, what the chimney will occupy, and then excavate a bit in that area and thus be able to place a solid base.
  3. Once the excavation in the ground, which does not have to be too deep, we must build the base , which can be made with cement or other resistant material, taking care that it is smooth and even in level.
  4. The following is the construction of the walls , we will make them with bricks, each brick should be placed next to another without leaving space between them, using high temperature resistant cement to join them together, we are placing rows of bricks, on them cement and more bricks and with the same cement we cover the holes that may remain.
  5. There are different ways for chimneys, if we want something simple we go directly to step 7, if we want the most conventional way, we should pay special attention to the front of the chimney. When building the walls in the front , we must leave an open space about two feet wide or so, depending on the size of the fireplace, that area must be covered with material of great resistance to fire, there are special bricks for that.
  6. Something fundamental in the traditional chimneys is also the exit of fumes, to solve it a pipe is inserted in the opening of the chimney in the superior part, when placing the bricks of the walls, we narrow the cabin, until we reach the upper part, the narrowest part in which we will fix the tube with cement, once the tube is fixed, we continue placing the bricks around it.
  7. Now, if we look for something simpler, we can forget the two previous steps to do something like what we see in the image of this article, a chimney of the simplest , its advantage is that it is easier to build and same time is just as functional as the others, but the smoke outlet is not as controlled, that is its drawback, here there is no front hole or tube to place, only walls with space in the center to place the wood and light the fire , on top of it you can place a grill if you want to cook over coals ..
  8. Once the structure is finished, in any of the cases, it is only necessary to decorate the exterior of the chimney to the taste, that is already a matter of the imagination of each one, for example, we can place some stone around, finally there is to take the wood, light the fire and check if the smoke outlet works properly.
  9. Finally, those who are not very handy, do not despair, if this seems too complicated or you are not for the work … I remind you that you can also buy the fireplace already made and simply limit to install it.

How to build a fireplace

There are many types of chimneys, but the ones that we associate universally with that name are the French chimneys. These chimneys require a complex masonry job that not everyone is able to tackle. Therefore we recommend that you consult a builder before undertaking this type of work if you do not have previous experience.

These chimneys are available in various sizes and formats, we can choose the one that best suits the room in which we are going to locate it.

We can use different materials to build the chimney: stone, slab or refractory brick, block, etc. These chimneys are regularized and their interior shape is not necessarily reflected on the outside, as the finish can hide the masonry behind wooden or plastered partitions.

Prefabricated draft regulators can be used, which are lined with refractory brick. At the top of the shot is a ledge that deflects the descending shots of the chimney.

When the exposed masonry is left, it is saved in finish and this allows to leave the brick wall completely seen. To harmonize, the remaining walls of the room will be revoked or covered, in this way the fireplace takes center stage.

How to make the fireplace:

First of all, we must define the location of the chimney, since its optimal functioning depends on it. It must be placed on a wall from which the heat is dispersed over as large a surface as possible.

If the chimney is located on an interior wall, we can also see the brick on the other side of the wall, creating a rustic decorative effect and also, the heat is better used.

For a French fireplace to function properly, the height of the fireplace opening must not exceed 84cm. It is usual to use prefabricated draft regulators with metallic grooves, which have better draft because they are smoother than those made of brick.

The smoke shelf of the draft regulator should be between 15 and 30cm deep with a smooth and concave surface. The chimney of the chimney should have a size according to the size of the chimney.

To build the chimney, we mark the area where it will be located on the ground and begin to place the bricks, forming the chimney box.

The floor is formed on a layer of refractory mortar, where the bricks or slabs are applied. It is possible to give it any shape you want. The placement of the floor is done from the outside inwards so that the cuts are at the bottom.

When the floor is dry, we lined the interior walls with refractory brick.

The extractor hood will be made with partition brick or tongue and groove. The wall of the hood is inclined at 45º and has a cone shape, up to the height where it connects with the chimney pipe. The hood is left to dry at least one day before applying the coating.

How to build a fireplace in the patio of the house

Thinking about a chimney when looking for a solution to counteract the cold during the winter season is an excellent option, since these in addition to maintaining the air conditioning inside the home perfectly, also comes to offer a striking style as this fills of beauty, elegance and originality to the space where it is installed, rapidly increasing its purchasing and aesthetic value.

Anyone can have a fireplace because they can even be made by the same people, mainly those directed to the patio or the garden, because they offer a much more pleasant fresh environment. To build one of these structures does not require much work or materials, the only thing that is required is to follow each of the steps that will allow creating a simple and at the same time beautiful outdoor fireplace.

The first step is the space where the chimney will be located, avoiding being near pipes, cables and things that may burn. After having the perfect space you should draw with a chalk the dimensions that the fireplace will occupy to take it as a reference when carrying out the excavations.

Subsequently the base must be built, for this you can make use of cement or a super resistant material, taking into account that it must be level and completely smooth. Then you must build the walls for it must use bricks, where each must be placed next to each other, the cement to be used must be very resistant, and must be at high temperature so that it can join each. The placement of the bricks should be in rows, where between one row and another should be placed cement and at the same time should be covering the gaps that may remain.

It should be made four walls that carry a space in the center, to decorate this structure you can use your imagination and interact with different materials such as decoration with stones that is spectacular.

How to build a construction chimney

When the house exists and you want to build a construction chimney, it will have to be located under a smoke outlet, shunt, that allows the smoke and carbon monoxide to go outside and that the outside oxygen enters to help combustion and that the indoor air is not contaminated, in the case that that smoke outlet does not exist, it will have to be located with the proper licenses and permits.

Resolved the location of the shunt, the draft of the chimney should have the appropriate section, proportional and calculated to the volume where combustion is going to be carried out and the length to be traversed until the exit of the gases and in addition the shunt should have a cusp that allows the air to come in clean and smoke out smoothly, so that it does not allow the dirty air to come back in through the draft and thus have a gas inhalation problem.

The fireplace can be installed free of wall or attached to it. The material with which the chimney forms must be refractory, that is to say that it supports the high temperatures that are formed and to which all the materials in contact are going to be submitted.

The materials usually have an RF card, usually come as RF-index, it will be a number that indicates the average fire resistance of the material or training in concrete, in minutes, for example RF-120. The hearth will be installed and over it the cladding and the hood, the rock wool will help to isolate the walls of the hood and then attach to the outside plasterboard plates, the joints will be treated and the whole chimney will form a perfect and unique composition. All the areas to which the chimney is attached should be perfectly insulated and conditioned for heat and fire.

The chimneys can be of open or closed home, the closed home is less romantic and aesthetic, but it is certainly safer and with greater calorific and distribution power.

Fundamentals for the construction of a fireplace

A fireplace is a nice addition for any home. It is an attractive center for a main hall and can add value to the house. The construction of a fireplace in the home is a great DIY project, and knowing the basics for its construction can save you time and money.


Find an ideal location for the fireplace in your house. If you are using generic plans for the construction of the fireplace make sure it will fit in the location you have chosen. Mark the place of the fireplace on the wall. You will have three main components: the home, the combustion chamber and the hood. The home protects the floor from the heat of the fire, the combustion chamber will surround the fire and the hood is a decorative piece that is built around the chimney.

Size of the fireplace

When taking initial measurements, it is essential that the depth of the chimney from front to back be two thirds of the height of the chimney. Therefore, a chimney that is 60 inches (152.4 cm) high must be 40 inches (101.6 cm) deep. This is to ensure that the smoke from the fire can be expelled through the flue, the pipe that carries the smoke outside the house. Make sure the area where the home will be located is level and check it constantly during construction.


Choose a hood design that complements the design of your home. There are many prefabricated homes that you can buy and you are free to make your own design. There are several styles that include rectangular openings, arched openings, corners (when a chimney is built in a corner and can be accessed from two sides), and a U-shaped opening, where the chimney is exposed on three sides. Choose the right hood for your design.

The Benefits of a Rustic Fireplace

There is nothing better than being cold and being able to curl up next to a fire with a good blanket and the company of loved ones. If you want to integrate a chimney into the decoration of your home, do not hesitate to do so because the warmth and the feeling of well-being that they bring will be unmatched.

In addition to these two advantages is a heat source allowing you to use natural heat in addition to the radiators in the room that you install. To ensure heat for a few hours or days, you will need a place to leave logs or coal next to the fireplace so you don’t have to go outside to find material to source the heat.

Enhancing a room with chimneys therefore has an endless number of advantages. A rustic type is a decorative option depending on the style of your house. In rural homes or those located in the mountains this choice is the perfect solution. In addition, you can make the chimney the size you want and with features to your liking.

You must install a protective glass to prevent the flames from going outside. This glass will be of a special type that does not allow the material to overheat avoiding contact burns. In addition, it allows to remove the heat in such a way to create a pleasant and well-heated room.

Construction and installation of chimney duct

Finally we need to communicate the chimney flue with the outside but first let’s review some parts of this manual:

Construction of the base: Explain how the coil chamber is built to take advantage of the heat of the home’s floor

Construction of the reflecting walls and Lung: These are the ones that give form to the combustion chamber and serve to reflect the radiation of the flames to the outside of the mouth.

Installation of the oven and bell closing: Here the lung was closed by means of a bell and on the

The same oven was installed that will serve in this example for the smoking of porcine products Identification of shooting problems: This is an annex which has a video describing how to solve problems of excessive or inefficient shooting, for the latter it is advisable to raise the shot or the installation of a weather vane.

Finally in this manual we will give construction of the smoke flue and provide a plan of measures of the stove, but this is only for guidance, our desire is not for the user to build a replica as is, so we give measurement relationships and suggestions and possible defects to be taken into account, in any case the plan as it was built this barbecue chimney contains the measurements and has been proven by identifying a defect of excessive draft, for which a record or valve of shot will be installed also known as balance.

In the above image, the oven can be seen, which is optionally constructed and the mouth of the oven can be closed with bricks located on the edge. Now the construction of the pipeline that will transport the combustion gases is not complicated, you only need to raise the 33 x 33 cm square to the ceiling.

They may choose other ways to take the duct outside, in this case we prefer the straightway, and it is to cross the earthenware or roof plate as is the case directly on the duct.

When we have a second plant or a complex fall, this is that if we make the hole could be at risk of large water leaks, we will choose to install an elbow and take the exit by the wall instead of the roof. In our case the slope of the roof is 7% and long to the chimney of 2.5 meters, although there may be a risk that the chimney represents rainwater and occasional leak, we expect that the zinc plate we cut has no joints, then we crossed the same medium of the sheet of 1.10 meters generating a hole of 33 x 33 we left enough space for the water to evacuate the sides.

At the time we lift the pipe we will the inside and outside this will allow us in the future a comfortable cleaning of the soot, because like any stove is very advisable to call the chimney sweep before the winter period begins, fire may occur in the shot if this It contains a lot of carbon crust adhering.

To prevent the water from entering the interior, in metal ceilings the sheet is bent as shown in the drawing in such a way that it acts as a dam. In this way, before falling inward, it discards the channels towards the ends. To cut the hole we use an angle grinder without removing the sheet from the ceiling, but keep in mind that it must coincide perfectly with the rise of the shot. To mark the edges of the square we drill with drill from below, helping with a level so that the hole serves as a guide for where to cut.

When the roof is made of concrete, we will proceed in the same way, marking with a drill and making a cut in the lower part of the tile with grinder and Widia disc. in the center, where the conduit will pass, we will make a hole with a drill, and then from the roof with allude of a short cold and we will enlarge the first hole created by the drill hole. We will leave the cut of the earthenware irons for the end, for safety reasons.

To elevate the pipe to lead with the help of a lapis we will draw its contour on the wall and this will serve as a guide, as usual we will the exterior while growing the courses, as seen in the part where the sky created a brick flange, this is to hide the juncture of same with the chimney and we avoid the installation of joint or half pipe, because the plaster sheet supports the eyelash that remains in sight.

The upper part seems very obvious to dealer, because it consists of elevating the pipe to the outside and it is completely different for each roof, vastly recommended to exceed 70 cm any wall or parapet that could repair the perfect evacuation of gases of combustion, in this installation metal stoves are better explained.

Brick industrial chimney

The industrial chimneys executed on the basis of a brick factory were one of the most emblematic elements of industrial architecture. Its construction derived from the need for the extraction of fumes from steam engines and the circulation of air that facilitated combustion, strongly marking the landscape that surrounded them.

The industrial chimneys executed on the basis of a brick factory were one of the most emblematic elements of industrial architecture. Its construction derived from the need for the extraction of fumes from steam engines and the circulation of air that facilitated combustion, strongly marking the landscape that surrounded them.

Currently, many of the examples of industrial architecture existing in Portugal are abandoned, given to a degradation accentuated by years of neglect. In spite of everything, there are still several industrial complexes where some emblematic fireplaces resist to the caprices of the abandonment and lack of maintenance.

The study fireplace was part of a ceramic elements factory founded in 1910 and represents an excellent example of the industrial architecture of the early s. XX. Its environment, which has undergone a deep development in the last ten years, has become a cultural and recreational area, turning the chimney into a singular construction to conserve. Like many other specimens of the same period, the chimney is built of solid bricks bound with lime mortar, with a maximum height of about 40 m.

The intervention of NCREP in the chimney consisted in the realization of a geometric survey through Laser Scanning technology, in the visual inspection in all its height, with registration of the points with damages and the intensity of these in own maps, and in the conducting a campaign of dynamic identification tests in situ, studying the environmental vibration. Finally, all the results collected served as the basis for the development of a numerical model of finite elements, with non-linear behavior, with the aim of evaluating their structural safety considering the usual acting actions.

How to Build an External Fireplace – Part 2

Determine the size of the chimney. Size must match the surroundings. Consider whether you want the fireplace to be the center point of the backyard or a complement to an already impressive view.

Try to design the chimney with proportions in mind. It is not recommended that the fireplace completely opacity the size of the house or be reduced by the size of the house.

Choose between firewood or gas. What kind of fireplace is best for you? Many outside fireplaces are either wood or gas. Each method offers advantages and disadvantages:

A wood-burning fireplace provides a natural view and emits a smell that gas fireplaces cannot match. A traditional fireplace also produces a significant amount of smoke, so you must have an exhaust built to strict specifications.

The most important consideration when constructing a gas fireplace is to connect the fireplace to an existing gas line. Gas fireplaces offer many advantages over wood-burning stoves: they do not produce ashes or embers, they do not need an exhaust and rarely require building permits. However, they do not burn so much and lack the rustic charm of a wood-burning unit.

If you are going to build a wood burning fireplace, get a building permit. Most firewood units require permits. Contact the municipal government about restrictions and other requirements. You can begin construction after obtaining the building permit.

The city must inspect the chimney before it can be used.

Find the gas line if you want a gas fireplace. The gas company can help you locate the line closest to the fireplace location.
