The presence of CE certificates and compliance with European standards confirm the high quality and safety of our products.
What do the CE marking and main EN standards mean? [+]
These are key European standards and markings that confirm our products meet the strictest requirements for safety, quality, and compatibility. For you, this is a guarantee that you are buying a reliable and certified product.
CE Marking:
This is a mandatory mark for products sold in the EU. Its presence confirms that the product has undergone a safety assessment. Our production is certified under System 2+, which implies strict Factory Production Control (FPC) and regular product testing.
Main standards for our products:
EN 1856 (for chimneys): This standard regulates all requirements for metal chimneys — from steel grade and heat resistance to fire safety.
EN 1090 (for load-bearing structures): This construction standard guarantees that all structural and support elements (masts, brackets, platforms) are manufactured in compliance with strict strength and safety norms.
EN 1505 and EN 1506 (for ventilation): These standards define the exact dimensions and tolerances for rectangular (EN 1505) and circular (EN 1506) ducts and fittings. Compliance ensures that all elements of your ventilation system will be perfectly compatible and airtight.
You can view all documents in the "Certificates" section.
What is the difference between standards EN 1856-1 and EN 1856-2? [+]
Both standards apply to metal chimneys but regulate different types of products. EN 1856-1 is the standard for insulated system chimneys (our IZOKOMPAKT), while EN 1856-2 is for single-wall components and liners (our RENOFAST). The fact that our products are certified under both standards guarantees you receive a safe and tested solution.
How to decode the full chimney marking? (T600, P1, W, L50, G50) [+]
Every certified chimney has a mandatory marking — a product passport that encodes all its key performance characteristics. Here is a breakdown of each parameter:
Applicable Standard (EN 1856-1): Indicates which standard the product is certified under (EN 1856-1 for systems, EN 1856-2 for liners).
Temperature Class (T600): The maximum continuous operating temperature (e.g., T600 = 600°C).
Pressure Class (P1): N1 — for natural draft (fireplaces), P1 — for positive pressure (pellet boilers with a fan).
Condensate Resistance (W/D):
W (Wet): Designed for wet operating conditions. This class is mandatory for appliances that constantly and actively produce condensate, such as condensing gas boilers.
D (Dry): Designed for dry operating conditions where condensate formation is minimal. Suitable for classic wood-burning stoves, fireplaces, and most modern pellet boilers, provided the system is installed and operated correctly.
Corrosion Resistance (V2): The corrosion resistance class (V2, V3 — enhanced).
Liner Specification (L50060): The material (L50 = AISI 316L steel, L20 = AISI 304 steel) and thickness (060 = 0.6 mm).
Sootfire Resistance and Distance (G50): G — resistant to sootfire (for wood), O — not resistant (for gas). The number is the safe distance in mm to combustible materials.
What is the EN 1090 standard and why is it important? [+]
EN 1090 is a key European construction standard that regulates the manufacturing of load-bearing steel and aluminum structures. It's important to understand that it applies not to the chimney pipes themselves (which are covered by EN 1856), but to all structural, support, and load-bearing elements.
What exactly does EN 1090 cover:
Load-bearing masts and trusses for free-standing chimneys.
Support platforms and service decks.
Structural wall brackets and other elements that bear the weight of the structure and withstand wind loads.
Why is this critically important for the client?
A manufacturer's EN 1090 certification is your guarantee of safety and reliability. It confirms that:
Strict Factory Production Control (FPC) is implemented.
All load-bearing elements are designed for specific loads.
Only certified, traceable materials are used.
Welding and manufacturing processes meet strict European norms.
This standard is mandatory for industrial chimney systems and complex projects where the strength of the supporting structures directly affects the safety of people and property.
Section 3: Chimney Systems
3.1. Choosing a Chimney and Materials
Which chimney to choose for a private house? [+]
The choice of a chimney for a house depends on two main factors: the presence of an existing chimney channel and the type of heating appliance.
If you are building a new chimney from scratch (inside or outside the house): Your definitive choice is an insulated sandwich chimney system like IZOKOMPAKT. It ensures maximum fire safety when passing through wooden floors and roofs. For modern interiors, its premium version NordicPipe with a matte black finish is ideal.
If there is already a brick chimney in the house: The best solution is to protect and upgrade it by installing a single-wall RENOFAST system (lining). This will protect the brickwork from deterioration and improve the draft.
In any case, the type of your boiler or fireplace must also be considered to select the correct steel grade.
Which chimney is best for a sauna? [+]
A chimney for a sauna operates under extreme high-temperature conditions, so it has special strength and safety requirements. The optimal solution is a combined system:
The starting section in the steam room: To connect the stove, it is best to use pipes made of 2 mm thick black steel. They can withstand extreme heat, and their walls radiate additional warmth, quickly heating the room.
Passing through the ceiling and roof: For fire safety, it is mandatory to switch to an insulated sandwich chimney system like IZOKOMPAKT T600. Its insulation will protect wooden structures from overheating.
Important recommendation: for maximum durability and reliability, depending on your requirements and budget, we can manufacture a sandwich chimney for a sauna with an inner pipe made of thicker steel (0.8 mm or 1.0 mm). This provides an additional margin of safety for intensive use.
Using a single-wall stainless steel pipe to pass through ceilings in a sauna is strictly forbidden.
Which chimney to choose for a solid fuel boiler or fireplace? [+]
Appliances that run on wood or coal are characterized by high flue gas temperatures and soot formation. Therefore, the chimney must meet two main criteria:
High heat resistance (T600 class): The chimney must be rated for a continuous operating temperature of up to 600°C.
Sootfire resistance (G-rated): The construction must withstand a short-term temperature spike during a sootfire event in the flue.
Our IZOKOMPAKT T600 (for new chimneys) and RENOFAST T600 (for lining) systems meet these requirements. As a standard, we use reliable heat-resistant AISI 304 steel, which is ideal for these applications. At the client's request, for maximum durability, it is also possible to manufacture it from acid-resistant AISI 316L steel.
Which chimney to choose for a gas boiler? [+]
For modern appliances operating with active condensation (especially condensing gas boilers) and under pressure (pellet boilers), the key factors are acid condensate resistance and airtightness.
A chimney for such equipment must meet the following requirements:
Material: The inner pipe must be made exclusively of acid-resistant steel grade AISI 316L (EN 1.4404). Regular stainless steel is quickly destroyed in an aggressive, wet environment.
Airtightness (Pressure class P1): Since many modern boilers use a fan that creates positive pressure, the chimney must be completely airtight (class P1). Such systems use special heat-resistant sealing gaskets at the joints to prevent flue gas leakage.
Alternative for low-temperature boilers:
For some models of gas boilers with very low flue gas temperatures, it is also possible to use special plastic flue systems. They are completely resistant to acids but are not designed for high temperatures.
Our specialists will help you choose the correct and safe solution depending on your boiler model.
What are black steel chimneys used for? [+]
Black steel chimneys are a classic solution for connecting wood-burning stoves and fireplaces to the main chimney shaft inside a room. They are chosen for three main reasons:
High heat radiation: The thick pipe walls intensely radiate heat into the room, acting as an additional radiator and increasing the overall efficiency of the heating appliance.
Aesthetic appearance: Unlike stainless steel, which can change color from high temperatures, black steel pipes are coated with heat-resistant matte paint. Their color harmoniously matches the design of most stoves and fireplaces, creating a finished and authentic look.
Maximum durability: We use thick-walled steel (2 mm), which provides the highest resistance to burnout and deformation even under very intensive use.
Why is a special chimney (SPNP) needed for a pellet boiler? [+]
Pellet boilers use a fan that creates positive pressure. The special airtight SPNP system with silicone gaskets ensures that flue gases do not leak into the room through the joints.
What steel grades do you use for chimneys and what is the difference? [+]
Choosing the right steel grade is fundamental to the safety and longevity of a chimney. We use several types of certified steel, each intended for its own purpose.
AISI 304 (EN 1.4301) – Our standard: optimal heat-resistant steel
Key feature: This is our standard and most popular choice. AISI 304 steel provides excellent heat resistance and durability at an optimal cost, making it the ideal solution for most applications.
Where it's used: Ideal for the inner pipes of chimneys for wood-burning stoves, fireplaces, and solid fuel boilers.
AISI 316L (EN 1.4404) – Specialized acid-resistant steel
Key feature: Contains molybdenum, which gives it maximum resistance to acids and corrosion, especially in a high-humidity environment.
Where it's used: Its use is mandatory for chimneys operating with gas, diesel, and pellet boilers that produce aggressive condensate. It is also available as a premium option for solid fuel equipment for those who want maximum durability.
AISI 430 (EN 1.4016) – Stainless steel for outer casings
Key feature: Has sufficient corrosion resistance for protection against atmospheric conditions but is not intended for direct contact with flue gases.
Where it's used: Used for the outer casing of insulated sandwich chimneys.
Black and carbon steel (e.g., DC01)
Key feature: Increased wall thickness (from 1.2 to 2.0 mm). It has high strength and excellent heat radiation.
Where it's used: For manufacturing thick-walled pipes for connecting wood-burning stoves and for airtight SPNP systems for pellet boilers.
Galvanized steel (DX51+Z275)
Key feature: Structural steel with a dense zinc coating for reliable protection against corrosion.
Where it's used: Used for manufacturing the practical and durable outer casing of sandwich chimneys, often as a base for powder coating.
3.2. Installation, Components, and Safety
What are the main components of a chimney system? [+]
Although every system is unique, there are a number of key components that ensure its proper and safe operation:
Tee-piece — a component for connecting the heating appliance to the main vertical chimney stack. It also provides access to the flue for cleaning and condensate drainage.
Inspection hatch (Clean-out) — a special door in the chimney that provides access for inspecting and cleaning the inner flue.
Condensate collector — an element, usually located at the bottom of the system, designed to collect and drain moisture (condensate) formed in the chimney.
Brackets and fasteners — structural elements for securely fastening the chimney to the wall or other load-bearing structures.
Roof flashing and storm collar — a unit that ensures a sealed and safe passage of the pipe through the roof, protecting it from precipitation.
Chimney terminal — the top element that protects the flue from rain and snow. Depending on the task, this can be a deflector (to enhance draft) or a spark arrester (to increase safety).
How to correctly calculate the chimney diameter? [+]
Proper selection of the chimney diameter is a key factor for stable draft, safety, and efficient operation of your heating appliance. There is one main rule and several important nuances.
The main rule:
The chimney diameter must not be SMALLER than the diameter of the flue outlet of your boiler, stove, or fireplace. This is the starting point for any calculation.
Important nuances affecting the calculation:
Chimney height: A very tall and straight chimney can create excessive draft, which sometimes needs to be adjusted.
Number of bends: Each elbow in the system creates additional resistance and reduces draft, which may require a calculation adjustment.
Expert recommendation:
Since an accurate aerodynamic calculation requires taking into account all system parameters, the safest and most reliable method is to consult with a specialist. Contact our engineers, provide them with the model of your heating appliance and the approximate height of the chimney, and we will perform an accurate calculation and select the optimal set of components for you free of charge.
Yes, self-installation is possible. We are always ready to provide you with full support: we will assemble all the necessary materials for installation and promptly provide a detailed manual.
What is "assembly by condensate" and "by smoke"? [+]
These are two fundamental principles for connecting chimney elements that ensure its airtightness and durability. The correct application of both methods is mandatory.
Assembly "by condensate"
This method is used for all vertical sections of the chimney. The principle is that the upper pipe is inserted inside the lower one. This is necessary so that condensate and precipitation flowing down the inner wall cannot leak out through the joint and remain inside the flue.
Assembly "by smoke"
This method is used for horizontal sections (e.g., from the boiler to the tee-piece). Here, conversely, the next pipe is fitted over the previous one. This assembly prevents flue gases from leaking through the joints, especially during ignition when the draft has not yet stabilized.
The correct alternation of these two methods guarantees a complete seal of the system against both moisture and smoke.
What is the required safe distance from the chimney to combustible materials? [+]
The minimum fire safety distance is the clearance from the outer surface of the chimney to any combustible structures. For our insulated chimney systems IZOKOMPAKT T450 and T600, this distance is at least 100 mm. For single-wall pipes RENOFAST T600, it is at least 500 mm.
How high should the chimney be above the roof? [+]
The correct height of the chimney above the roof ensures good draft. The height depends on the pipe's location relative to the roof ridge:
If the pipe is within 1.5 m of the ridge, it must be at least 0.5 m higher than the ridge.
If the pipe is between 1.5 m and 3 m from the ridge, its top must not be lower than the ridge level.
If the pipe is more than 3 m from the ridge, its top must not be lower than a line drawn downwards from the ridge at an angle of 10° to the horizontal.
What does the cost of chimney installation depend on? [+]
The exact price is always calculated individually, as the final cost depends on many factors:
The height and diameter of the chimney.
The number of passes through walls, floors, and the roof.
The type of roofing material (to ensure a proper seal).
The need to dismantle an old chimney.
The complexity of the work (e.g., the need for custom brackets).
The distance of the site from Riga.
To get an accurate estimate, please request a free consultation with our specialist.
Is a permit required to install a chimney? [+]
For most private houses in Latvia, a separate permit for installing or replacing a chimney is not required. However, its installation must strictly comply with all current building regulations of the Republic of Latvia (LBN) and fire safety requirements. We take full responsibility for ensuring that all our work meets these standards.
What needs to be prepared on-site before the installers arrive? [+]
For high-quality and efficient work, please ensure clear access to the installation area (both inside and outside, including access to the roof). If work is being done in a residential area, we recommend removing or covering furniture and interior items with protective film to shield them from construction dust.
3.3. Operation and Maintenance
What is condensate in a chimney and why is it dangerous? [+]
Condensate is moisture that forms in a chimney when flue gases cool. Its danger strongly depends on the type of fuel.
For wood-burning stoves and boilers:
Here, condensate mixes with soot to form creosote — a black, tar-like, and extremely flammable substance. The accumulation of creosote is the main cause of soot ignition and chimney fires. Our standard stainless steel AISI 304 perfectly withstands these conditions with proper chimney operation (using dry wood, regular cleaning).
For gas, diesel, and pellet boilers:
In this case, the condensate is a weak acid that is very aggressive in destroying brickwork and certain steel grades. Therefore, for such heating appliances, the use of acid-resistant steel AISI 316L is a mandatory requirement for the long and safe service of the chimney. If a client wants maximum protection for a wood-burning boiler as well, they can also choose the more expensive system made of AISI 316L.
What is reverse draft and why is smoke coming into the room? [+]
Reverse draft is a dangerous phenomenon where smoke enters the room instead of being exhausted outside. The main causes are:
Insufficient chimney height;
Blockage in the flue (soot, debris, bird nests);
Lack of make-up air in an airtight house (plastic windows);
Incorrectly sized pipe diameter.
How to combat reverse draft? (Main solutions)
Increasing the chimney height: If the pipe is in a wind downdraft zone, it must be extended to the correct height relative to the roof ridge.
Professional flue cleaning: Regular cleaning removes soot and any blockages, restoring normal passage for flue gases.
Providing make-up air: Installing a wall or window air inlet valve provides the fireplace or stove with the necessary air for combustion.
Installing a special terminal: To protect against wind downdrafts, a deflector or a rotary cowl (turbo-deflector) is installed on the chimney top. We manufacture and sell such devices. They use wind power to create additional suction (draft) in the flue and effectively prevent wind from blowing down the chimney.
Important: only a specialist can determine the correct cause of the problem and the optimal solution after an inspection. If you experience reverse draft, stop using the appliance immediately and contact us for a consultation. We will help diagnose the issue and propose an effective solution.
How often and how should a chimney be cleaned? [+]
The frequency of chimney cleaning in Latvia is regulated by the Cabinet of Ministers Regulation No. 238 on Fire Safety. The requirements depend on the intensity of use.
Legal minimum for private houses: For solid fuel boilers, stoves, and fireplaces, mandatory cleaning and technical condition checks must be carried out at least once a year, before the start of the heating season.
Recommendation for intensive use: If you use the heating appliance constantly throughout the season, for maximum safety, we and many experts recommend cleaning it twice: before the season starts and once in the middle of it.
Important rules:
To clean stainless steel chimneys, you should only use special non-metallic (plastic or nylon) brushes to avoid damaging or scratching the inner surface of the pipe.
We remind you that to maintain the 10-year warranty on our systems, it is necessary to have reports from a certified chimney sweep confirming annual maintenance.
Thanks to our modern equipment, we are ready to implement almost any technical or design solution, including:
Hoods for mangals and grills: Specialized hoods for the effective removal of smoke, which can be equipped with spark-arresting meshes and painted in any color.
Industrial hoods: Local exhaust systems for welding stations, laboratories (made from chemical-resistant AISI 316L steel), and other production processes.
Hoods of any configuration: We can manufacture a hood of almost any shape and size based on your sketches or technical specifications.
You can choose not only the shape but also a wide range of materials, from various grades of stainless and galvanized steel to copper. To receive a price quote, please send us a drawing or sketch.
What is the difference between a wall-mounted and an island hood? [+]
The main difference lies in their location and installation method:
Wall-mounted hoods (Article: AFS) are installed against a wall, directly above the line of cooking equipment (stoves, fryers, grills) located along the wall.
Island hoods (Article: AFC) are mounted to the ceiling above equipment located in the center of the room, forming an "island".
A supply-exhaust hood (Article: AFP) is a more complex system that not only removes hot and contaminated air but also simultaneously supplies fresh air locally to the work area. This is necessary to create a balanced microclimate and compensate for the negative pressure created by a powerful exhaust system, which prevents drafts and reverse draft issues.
A hood with or without a filter (steam hood)? Which to choose? [+]
The choice depends on the type of emissions that need to be removed:
Hoods with grease filters (Articles: AFS, AFC, AFP) are mandatory for installation above cooking equipment where grease aerosols are produced (kitchens, grill areas). Their main task is to capture grease particles, reducing the risk of fire.
Hoods without filters, or steam hoods (Article: BFN), are designed to extract water vapor, hot air, or non-greasy fumes. They are installed above dishwashing equipment, in bakeries, or in industrial settings—for example, over welding stations to remove smoke or in laboratories to remove chemical fumes.
What steel is best for a kitchen hood? [+]
For professional kitchens and food production facilities, we exclusively use certified stainless steel as it meets all sanitary standards. The choice of a specific grade depends on the intensity of use and the type of equipment:
AISI 430: A practical and budget-friendly option for standard conditions.
AISI 304: The most popular choice, offering enhanced corrosion resistance. Recommended for most professional kitchens.
AISI 316L: Acid-resistant steel, necessary for facilities with particularly aggressive environments (e.g., constant use of harsh cleaning agents or proximity to the sea).
Can the hood be painted in a different color? [+]
Yes, of course. For projects where interior design is important (e.g., open kitchens in restaurants), we offer galvanized steel hoods with a powder-coated finish in any color from the RAL catalog. This allows the equipment to be perfectly integrated into the overall style of the room.
4.2. Technical Details and Installation
Labyrinth or mesh filter — what's the difference? [+]
We produce and equip our hoods with both types, but we always recommend choosing labyrinth filters as the professional standard for kitchens.
In a labyrinth filter, the air stream repeatedly changes direction, causing heavy grease particles to impact the metal plates and drain into a collection channel. Mesh filters are simpler but less effective.
Key advantages of labyrinth filters:
High efficiency and fire safety.
Durability: We manufacture them from stainless steel (AISI 430 or 304), and they are designed to last for the entire service life of the hood.
Easy maintenance: They can be easily removed and cleaned by hand or in a dishwasher.
How to correctly calculate the size of an exhaust hood? [+]
To effectively capture all emissions, the exhaust hood must be larger than the equipment area and overhang it with the following clearances:
On the sides: 150-200 mm on each open side.
At the back (for wall-mounted hoods): 50-100 mm.
At the front: 200-300 mm.
Example: for a 1000×600 mm stove, the optimal size for a wall-mounted hood would be 1300-1400 mm (width) by 800-900 mm (depth).
At what height should an exhaust hood be installed? [+]
The recommended installation height is 1800-2000 mm from the floor to the bottom edge of the hood. Installing it lower may interfere with staff, while installing it higher will significantly reduce its capture efficiency.
What kind of fan (motor) is needed for an exhaust hood? [+]
The fan's performance is selected based on an aerodynamic calculation that considers the hood size, duct length, and diameter. We offer reliable and quiet CK series duct fans from the Swedish manufacturer H. Östberg AB.
At your choice, they can be equipped with a standard AC motor or a more modern and energy-efficient EC motor, which consumes significantly less electricity and allows for precise speed control.
Can lighting be installed in an exhaust hood? [+]
Yes, at your request, we can equip the hood with built-in lighting. We install sealed LED lamps with a high protection class (IP65), designed for safe operation in the high humidity and temperature conditions of a professional kitchen.
Is it necessary for the hood's body to be welded? [+]
We manufacture our hoods with a welded body. Unlike cheaper, riveted alternatives, a welded construction has fewer seams. This is critically important as it reduces the risk of grease and condensate leaks and increases the overall strength and hygiene of the structure.
How to calculate the required performance of an exhaust hood (air flow rate, m³/h)? [+]
The correct calculation of performance (the required air flow rate, measured in m³/h) is a key condition for effective ventilation. The calculation depends on many factors:
The size of the hood and its open area.
The type and power of the cooking equipment under the hood.
- The installation height of the hood. - The length, diameter, and complexity of the duct run.
While there are engineering formulas for calculating the required air flow, to guarantee a correct result, we strongly recommend entrusting this calculation to specialists. Contact our engineers, and we will perform an accurate aerodynamic calculation for your facility free of charge.
4.3. Operation and Regulations
How often should grease filters and the entire system be cleaned? [+]
Regular cleaning is a critical safety requirement. The recommended cleaning frequency for ductwork depends on the intensity of use:
High (more than 12 hours/day): Once every 3 months.
Moderate (6-12 hours/day): Once every 6 months.
Low (up to 6 hours/day): Once a year.
Grease filters need to be washed much more frequently, depending on the kitchen's workload.
What standards do your exhaust hoods meet? [+]
As an EU-based manufacturer, we design our systems to meet stringent European and local regulations. For example, in our home market of Latvia, our professional kitchen hoods must comply with strict requirements from multiple authorities, ensuring the highest level of safety and hygiene.
Fire Safety (based on VUGD requirements): Our hoods are built using non-combustible materials like stainless steel with sealed welded seams. They are equipped with certified grease filters (with at least 95% efficiency) to prevent the accumulation of flammable grease and reduce fire hazards in the ductwork.
Sanitary Hygiene (based on PVD requirements): Our hoods are designed for professional food environments, using smooth, easy-to-clean, and corrosion-resistant materials (like AISI 304/316 steel). The construction prevents dirt accumulation and allows for easy cleaning and disinfection.
This commitment to meeting specific, demanding local standards ensures that all our products are built to a high level of safety, reliability, and quality, no matter where they are installed.
