Online StoreMasonry Chimneys are a Proven Solution for New Builds and Traditional Homes
Masonry chimneys are suitable for all types of heating appliances, regardless of fuel type – wood, pellets, oil, or gas. If you are building a new house from the ground up and want a traditional look for your chimney, masonry chimneys are the right choice for you.
Why Do We Still Swear by Masonry Chimneys?
Ideal for Masonry Houses
A masonry chimney is the best choice for classic new builds where the foundation is already being laid – it allows for optimal integration into the building's architecture.
Stainless Steel Flue for Better Draft
Inside, we use stainless steel (inox/rostfrei) pipes, which allow for a rapid temperature increase and reliable draft – less soot, better combustion, and greater safety.
Fire Safety
Rock wool insulation and cement bricks ensure resistance to high temperatures, mechanical stability, and protection of surrounding structures.
Free Inspection and Consultation
Our expert will visit your site anywhere in Slovenia and advise you on the most optimal solution – no obligation, no hidden costs.
Lower Cost for New Construction
Karodi masonry chimneys are typically 10–20% cheaper than prefabricated ones for comparable performance – without compromising quality or safety.

There are 3 Main Types of Masonry Chimneys
Chimneys have changed considerably over the years. Classic solutions without flues have been replaced by modern systems, which seal better, provide better draft, and are a safer choice for your home.
Classic Masonry Chimneys
are built from brick without inner flues. Due to leakage, they are no longer built today.
Masonry Chimneys with Fireclay Flues
are resistant to high temperatures and have a longer lifespan, but they heat up slower, which can cause condensation of flue gases.
Masonry Chimneys with Stainless Steel Flues
are a modern solution where a stainless steel (inox) flue is used instead of a fireclay one.
- They provide better and faster draft.
- They are lighter, reach operating temperature faster, and are more resistant to acids and temperature changes.
- Stainless steel pipes have a smooth inner surface, which facilitates cleaning and reduces soot buildup (lower risk of chimney fires).
How to Choose the Right Masonry Chimney?
Single Chimney
- One chimney flue
- Suitable for one heat source (e.g., one fireplace, stove, or boiler), under special conditions multiple appliances
- Used in smaller houses or buildings with a single heating system
Double Chimney
- Two separate chimney flues
- Allows connection of two separate heating appliances, which can be for the same or different fuels
- Greater heating flexibility – for example, you can have a fireplace in the living room and a central heating stove in the basement
Single / Double Chimney with Ventilation Shaft
The ventilation shaft, or fresh air supply, is a special channel (separate from the chimney flues) that can be used for:
- External air supply for the heating appliance
- Ventilation shaft
- Range hood exhaust or similar
How is a Modern Masonry Chimney Constructed?
Modern masonry chimneys are composed of several layers that ensure efficient draft, safety, and a long lifespan.
Inner Pipe
Made of high-quality stainless steel, resistant to corrosion and high temperatures.
Insulation Layer
High-density rock wool, resistant to high temperatures and designed to reduce heat loss and prevent condensation.
Outer Casing
Made of aluminum or stainless steel, resistant to weather conditions, light, and mechanical stress.
Chimney Top Section
The chimney top section is crucial for protection against weather influences and ensuring long-term stability.
At Karodi, we offer several solutions for protecting the chimney above the roof:
- Metal finishing covers – made of aluminum
- Finishing elements – imitation masonry
Top sections are available in various RAL shades, allowing for aesthetic coordination with the building.
White (RAL 9010)
Black (RAL 9005)
Brick Red (RAL 8004)
Silver (RAL 9006)
Dark Red (RAL 3009)
Dark Brown (RAL 8017)
Anthracite (RAL 7016)
Which Chimney is Best for your Home?
In addition to masonry chimneys with an internal stainless steel pipe, you can also opt for prefabricated triple-layer chimneys.

Masonry Chimney
Modular (Triple-Layer) Chimney
Masonry Chimney
Building type: Masonry new builds
Price: 10–20% lower price
Flexibility: Less flexibility (requires a foundation due to load-bearing capacity)
Construction time: More time
After installation: After installation, requires drying and finishing (plaster, final facade layer, etc.)
Modular (Triple-Layer)
Chimney
Building type: Prefabricated new builds Existing and occupied buildings.
Price: Higher price than masonry chimneys
Flexibility: Starts at any height Has axial offset option.
Construction time: Less time.
After installation: Immediate use.
Do You Already Have a Dilapidated Chimney?
Renovation is often the best solution if you already have an existing masonry chimney that is:
- Dilapidated or cracked, but still structurally stable
- Unsuitable dimensions for a new stove (too small diameter)
- Leaking condensate or flue gases, which is dangerous
- No longer compliant with modern heating appliances.
- Karodi Masonry Chimneys
Why Choose Karodi Masonry Chimneys?
At Karodi, we provide certified and tested chimney systems that are adapted to the needs of modern buildings and heating appliances.

Better Performance
Compared to similar chimneys with fireclay flues, masonry chimneys with stainless steel flues provide:
- Less condensation – higher flue gas temperature reduces the risk of condensation and corrosion.
- Better chimney draft – more stable flue gas extraction improves stove performance and increases safety.
- Greater energy efficiency – reduced heat loss allows for lower fuel consumption.
- Long lifespan.

Frequently Asked Questions from our Customers
Are Masonry Chimneys Still a Good Choice Today?
Of course – especially for classic, masonry new builds. Masonry chimneys are a proven, safe, and durable solution. In combination with an internal stainless steel flue, they provide excellent draft, robustness (high resistance to high temperatures, weather influences, etc.), and a long lifespan for the chimney system.
What Types of Masonry Chimneys Exist?
There are four basic designs of masonry chimneys:
- Single chimney – contains one chimney flue.
- Single chimney with ventilation shaft – in addition to the chimney flue, it has an additional air duct.
- Double chimney – contains two separate chimney flues.
- Double chimney with ventilation shaft – includes two chimney flues and one air duct.
The ventilation shaft allows for fresh air supply (e.g., for a fireplace stove) or air extraction from rooms (e.g., for a kitchen hood).
What is the Purpose of the Air Duct Next to the Chimney?
The air duct (ventilation shaft) is not intended for exhausting flue gases. It can serve as a fresh air supply (most commonly for a fireplace stove or other heating appliance, as air supply in modern sealed buildings is crucial for safe burning) or as air extraction from rooms (e.g., for a kitchen hood).
What is the Difference between Fireclay and Stainless Steel Flues?
Does a Masonry Chimney Require Additional Finishing?
What is the Lifespan of a Masonry Chimney?
A masonry chimney with proper construction and a stainless steel flue has a lifespan of 30 years or more. With the use of certified materials and professional installation, we guarantee long-term reliability – which is why we also offer a 10-year warranty on the chimney system and all performed installation work.
Is a Masonry Chimney also Suitable for a Pellet or Gas Stove?
Can I Relocate or Offset a Masonry Chimney?
When is it Better to Choose a Prefabricated Chimney?
A prefabricated (triple-layer) chimney is an ideal choice if:
- you are building a prefabricated house,
- the building is already constructed (or even occupied) and a chimney was not planned,
- you need an offset due to windows, beams, or other obstacles.
Masonry chimneys are more suitable for classic new builds where sufficient space is available and static load-bearing capacity is ensured.
