How to build a corner fireplace

A fireplace can add coziness, warmth, and atmosphere to any room in your house. However, if you’re thinking about installing a fireplace, why not choose something special and endearing like a corner fireplace? In addition to providing useful heat, corner fireplaces become focal points that give your house personality and flair. We’ll go over every step of creating your own corner fireplace in this guide, from installation and finishing touches to planning and preparation.

It’s crucial to measure your area and choose the best spot for your corner fireplace before starting construction. Take into account the room’s design, traffic patterns, and the fireplace’s compatibility with the current furnishings. Corner fireplaces work especially well in smaller spaces or places where making the most of available space is important. After deciding on the ideal location, get your supplies and equipment ready.

Effective planning and preparation are essential for any fireplace construction project to be successful. Using chalk or masking tape, start by drawing the dimensions of your corner fireplace on the wall and floor. Next, assemble the required building supplies, such as cement board, mortar, bricks, stone, or prefabricated fireplace parts, along with an appropriate firebox insert. Make sure you also have on the proper protective gear, such as dust masks, safety glasses, and gloves.

Now that you have your plans set and your materials prepared, it’s time to start building. Building the fireplace’s base should come first. Make sure it is level and firmly fastened to the ground. Next, build the fireplace’s walls by stacking bricks or stone and caulking the spaces between them. To make sure that everything fits snugly in the room’s corner, pay close attention to the angles and measurements. Keep an eye out for plumb and level as you build upwards to ensure a straight and sturdy structure.

It’s time to install the firebox insert once the fireplace’s basic framework is in place. As the combustion chamber where the fire will burn, this part needs to be carefully placed and fastened in accordance with the manufacturer’s instructions. After the firebox is in position, build around it by putting in more brick or stone layers until the height that you want is achieved. To add the final touch, cover the fireplace’s top with a mantle or other decorative trim that fits the space.

After the building process is finished, take some time to check your corner fireplace for any cracks or imperfections. For a polished finish, smooth out any sharp edges and fill in any gaps with caulk or mortar. After everything is set up, it’s time to start your first fire and take in the coziness and warmth of your freshly constructed corner fireplace. Your corner fireplace will quickly become a cherished focal point in your house, whether you’re spending a cozy night in with loved ones or curling up with a book on a chilly evening.

Where to start the construction of the fireplace?

These heat sources use infrared radiation to heat the room within visible range and have similar efficiency levels (15%). Modern fireplaces featuring an integrated metal fire are an exception. Actually, this is actually the same wood stove that looks like a fireplace; it has an efficiency of 45–50%.

There are many corner fireplace projects available, so you should first determine which one is best for you. Sources: specialized websites, technical publications, and even this article, in which we’ll outline a few straightforward schemes for your perusal. The following is the action algorithm:

  • Calculation of the corner fireplace in accordance with the size of the room:
  • selection of the project and, if necessary, its adjustment for your area;
  • preparation of tools and materials;
  • foundation device;
  • the construction of the hearth itself;
  • Trinous clan.

Note: It is sometimes done to face the fireplace’s walls with different materials from the room’s interior.

Calculation of the size of the fireplace

The fireplace device below the figure illustrates the main components that will help you understand what we will be discussing later:

It is calculated what the combustion chamber and chimney section sizes are. It will smoke inside or provide very little heat if it is too big or, on the other hand, too small for your room. Thus, certain guidelines are followed in the construction of fireplaces:

  • The area of the open part of the furnace (otherwise – the portal, the mouth) is no more than 2% of the square of the room. Moreover, its height does not exceed the depth of the fuel more than 2 times;
  • The throat of the furnace has a size equal to the area of the mouth multiplied by a coefficient of 0.7;
  • The width of the fuel is 20-40% more than its height. The depth is determined by multiplying the value of the height by the coefficient of 0.5-0.7;
  • The chimney in the lower part has a cross section that is 10-15% of the portal area. In this case, it is recommended to observe the conical shape of the passage section of the chimney;
  • the height of the chimney from the fireplace to the cut of the pipe – at least 5 m. Minimum section – 140 x 270 mm;
  • In the presence of a blowing channel in the design, its cross section must be kept in size of at least 200 cm2.

The size of each component of the corner fireplace is displayed in the table below for rooms of varying areas, making it easier to calculate the fireplace’s dimensions:

The choice of a corner fireplace project

Consider a few projects that seem interesting in terms of how simple the work is. The first is a standard fireplace suitable for a 15 m2 small room. If the dimensions of your room are large, you will need to recalculate the project using the updated information.

You will find it challenging to select a shame for new sizes, so you will need the assistance of an expert stove maker. Below is a regrettable example of a basic design corner fireplace:

Although the next project is a little more involved, both the heat transfer efficiency and the visual appeal of it make it more intriguing. This fireplace, measuring 62 by 52 cm, is intended for rooms that are between 15 and 20 square meters in size. This focus’s device not only has lower air intake holes, but also upper openings, or stuffy openings, from which heated air exits, intensifying the heating of the space. To construct this corner fireplace stove, the following supplies and furnace equipment will be needed:

  • Brick red ceramic size 250 x 120 x 65 mm – 320 pcs.;
  • Clay – 0.1 m3;
  • Sand – 0.1 m3;
  • door with dimensions 130 x 140 mm – 1 pcs.;
  • grate is grate 250 x 250 mm;
  • Steel sheet (stainless steel) 2-3 mm thick – 0.3 m2;
  • Steel sheet with thickness 2-3 mm – 1.15 m2;
  • corner 32 x 32 x 4 mm – 0.7 m;
  • Ruberoid – 2 m2;
  • Asbestos in sheets – 1.5 m2.

Note: The materials required to construct a brick corner next to the chimney are specified. Depending on the height of the ceiling and roof, an additional 120 to 180 pieces of red brick will be required for the masonry.

The design calls for using 2 mm diameter soft structure steel wire to reinforce masonry. Furthermore, the chimney’s internal passage is constructed from standard sheet steel and covered with a 60 mm-separated brick; the internal section’s dimensions should be 130 x 260 mm. Stainless steel is also used to make the reflecting screen that is mounted inside the firebox. drawings of the ash box and other details in the figure:

The order and drawings of the corner fireplace with increased heat transfer can be seen in the following figure:

This post will explain how to construct a corner fireplace, which is a useful and attractive addition to any house. A corner fireplace is a great option for both practicality and style since it enhances room layout options while simultaneously adding warmth and coziness to your area. We’ll go over the fundamental processes of building a corner fireplace, from design and setup to installation and touch-ups. This guide will give you all the information you need to build a gorgeous and useful corner fireplace that improves the atmosphere and comfort of your house, regardless of your level of experience with do-it-yourself projects.

Preparatory stage

Purchasing the required tools and building materials is one step in the preparation process. The primary component is ceramic brick, which should have smooth side surfaces, be full-bodied, and be free of visible damage and cracks.

Note: The same stringent requirements apply if the project calls for masonry using fuel from chamotis (refractory) brick.

A basic set of tools is required, even for building a small fireplace, and includes:

  • measuring devices (level, roulette, plumb);
  • pantries (cell, trowel, grater);
  • Cutting tool or stones (chirus, grinder).

The foundation of every corner classic brick fireplace is typically a 1:1 clay-sand solution. The ready-made dry form is available for purchase in retail stores, or you can use the grandfather’s method, which involves digging clay, soaking it in water for three days, and then straining it through a sieve. Water is added to the mixture just enough so that the solution slides off the trowel without being overly wet.

The foundation device

The foundation in the form of a slab of reinforced concrete is the simplest and most dependable. In order to accomplish this, you must dig 30 cm into the ground, compact it, and then pour a 100 mm-high pillow of crushed stone. Install the formwork from the boards after pulling back 50 mm from the existing walls, and cover it with a plate covered in plastic wrap. It will keep milk from leaking out of concrete and act as waterproofing.

Vital. The foundation’s measurements must be at least 5 centimeters larger in both directions than the fireplace’s measurements. Associating it with the building’s base is forbidden.

Laying a mesh tied from reinforcement with a diameter of 10–12 mm on little stands inside doesn’t harm anything. The mesh cells are between 100 and 150 mm in size. The following is the concrete’s composition when stirred by hand: One part M400 cement, three parts sand, and seven parts medium-sized medium-sized. After ready concrete is poured into the formwork over the film, it is leveled out with a grater and allowed to cure for three weeks.

The construction of the corner fireplace

The construction of brick furnaces and the laying of a fireplace are essentially the same process. After covering the base with roofing material, the order is followed when creating the masonry. Prior to construction, asbestos sheets are used to cover the surface of the walls next to the fireplace. It is then advised to apply a layer of aluminum foil that reflects heat. The following guidelines must be followed when performing panting work:

  • Each row is laid out “on dry”, adjusted stones, and then put on the solution;
  • Bricks before laying are necessarily immersed in the water for a couple of minutes;
  • The solution is applied with a trowel on the previous row, and not on a new brick;
  • Brick in place is fixed with a strong press or light lashing;
  • The most smooth side of the stone should be turned inside the fireplace;
  • The remains of the broken solution are removed, and the wall is wiped dry every 3-4 rows.
  • Compliance with horizontal and vertical is checked on each row of masonry.

Suggestions. It is advised not to notify the front portion of the wall during the masonry process if corner fireplace designs are not intended. After that, a lovely slit-like seam appears.

Hypsum-plane

The market introduction of numerous contemporary products and materials has resulted in a significant simplification of fireplace construction. Electric firewood in decorative designs and metal fireplaces with glass doors gained popularity. Actually, a sandwich pipe chimney is attached to a metal firebox, which is the same furnace itself. The exterior of the building is constructed to resemble a fireplace. Drastic sheeting is used for this, as the diagram illustrates:

Vital. For fire safety, you must use fireproof drywall when installing a metal firebox by hand and setting it up as a corner fireplace.

As you can see, the chimney pipe is sewn with drywall sheets, and the masonry, whether brick or stone, is only constructed to the height of the fireplace. They have ventilation grilles integrated into them for air circulation. You can install an electric fake fireplace and cover it with drywall using galvanized profiles, which is even simpler and doesn’t require a foundation.

Note: Although the picture depicts the assembly of a traditional wall fireplace, the installation concept is still the same.

There are many options for contacting GCL, including artificial stone, wallpaper, and other materials. Although a similar drywall corner fireplace won’t provide much heat for the home, it will look fantastic as a light feature.

Constructing a corner fireplace can add charm and warmth to any house, serving as a gathering place and source of warmth. You can make your living area more aesthetically pleasing and functional by adhering to a few essential steps and creating a warm and inviting space.

First and foremost, you must carefully consider where to put your corner fireplace. Take into account elements like traffic flow, room layout, and closeness to combustible materials. Selecting the ideal location enhances the fireplace’s aesthetic value and guarantees safety.

Choosing premium materials for construction is essential for longevity and effectiveness. When choosing a material for your fireplace, be it stone, brick, or tile, give special consideration to materials that are resistant to heat. Moreover, making an investment in fireproofing and adequate insulation will help reduce the risk of fire hazards and prevent heat loss.

Ensuring the safety and efficacy of your corner fireplace requires proper installation. If you’re not sure you can do it yourself, it’s best to work with a licensed contractor with fireplace installation experience. They can guarantee that the fireplace complies with building codes and regulations, is constructed securely, and is appropriately vented.

Remember to maintain your corner fireplace after it is installed.
