Step by Step: Building a False Chimney Breast for Your Fire

A chimney breast can add a stunning focal point to any room, creating a cozy and charming atmosphere. But what if your home doesn’t have a real chimney? Don’t worry! You can build a false chimney breast that looks authentic and allows you to enjoy the warmth of a fire. Here’s a step by step guide to help you create a false chimney breast for your fireplace.

Why Build a False Chimney Breast?

Building a false chimney breast has several benefits:

Aesthetic Appeal: Adds a classic and elegant touch to your room.
Versatility: Works with electric, gas, log burners, or even some bioethanol fires.
Cost-Effective: Less expensive than installing a real chimney.
Customization: You can design it to suit your style and space requirements.

Materials and Tools You’ll Need

Before you start, gather the necessary materials and tools:

Materials:

Timber or metal studs
Plasterboard (drywall)
Screws and wall plugs
Fireplace (electric, gas, log burner, or bioethanol)
Fire-resistant board (if using a gas, log burner, or bioethanol fire)
Twinwall flue system (if using a log burner)
Paint or wallpaper for finishing

Tools:

Measuring tape
Spirit level
Drill
Screwdriver
Saw
Trowel and plaster

Step by Step Guide

Step 1: Plan and Measure

Start by planning the size and shape of your false chimney breast. Measure the area where you want to install it, considering the dimensions of your fireplace. Mark the outline on the wall with a pencil.

Step 2: Build the Frame

Construct a sturdy frame using timber or metal studs. This frame will support the plasterboard and the weight of the fireplace. Ensure the frame is securely attached to the wall and floor. Use a spirit level to make sure everything is straight and level.

Step 3: Install the Fireplace

Position your fireplace within the frame according to the manufacturer’s instructions. If you’re using a gas, log burner, or bioethanol fire, make sure to install fire resistant board around the firebox area for safety. For a log burner, ensure you have space for the twinwall flue system.

Step 4: Install the Twinwall Flue System (For Log Burners)

If you're installing a log burner, you will need a twinwall flue system to safely vent the smoke outside. This system consists of double-walled pipes that provide insulation to keep the outer wall cool while the inner pipe carries the hot gases. Follow the manufacturer’s guidelines to properly install the flue system, ensuring it passes through the ceiling and roof or an external wall safely.

Step 5: Attach Plasterboard

Cut plasterboard to fit the frame and screw it into place. Make sure to leave an opening for the fireplace. Use joint tape and plaster to cover the seams and screw holes, creating a smooth surface.

Step 6: Finish the Surface

Once the plaster is dry, you can paint or wallpaper the false chimney breast to match your room’s decor. Consider adding a mantelpiece or decorative elements to enhance the look.

Step 7: Connect the Fireplace

For electric or gas fireplaces, connect the unit to the power or gas supply as per the manufacturer’s instructions. Ensure all connections are secure and safe. For bioethanol fires, follow the setup guidelines provided by the manufacturer. For log burners, ensure the twinwall flue system is securely connected and venting properly.

Safety Tips

Ventilation: Ensure proper ventilation, especially for gas, log burners, and bioethanol fires.
Fire-Resistant Materials: Always use fire-resistant materials around the fireplace.
Professional Help: If you’re unsure about any step, especially the installation of gas lines, electrical connections, or the flue system for a log burner, seek professional assistance.

Building a false chimney breast is a fantastic way to add character and warmth to your home without the need for a real chimney. By following these steps, you can create a beautiful and functional focal point that enhances your living space. Whether you choose an electric, gas, log burner, or bioethanol fire, a false chimney breast can accommodate your needs.
