Insulated Sandwich Chimneys: IZOKOMPAKT and NordicPipe Premium Series
Insulated (double-walled) chimneys are modern, safe, and efficient systems for venting combustion products from any heating equipment. Their triple-layer design, also known as a "sandwich" or "twin-wall" structure, ensures maximum fire safety and stable operation of heating appliances.
All our systems are manufactured at our facility in Riga, using certified European materials and advanced technologies, such as laser metal cutting and robotic TIG welding, which guarantees perfect geometry and airtightness for every component.
IZOKOMPAKT Universal System
IZOKOMPAKT is our standard and most popular series of insulated chimneys. It is the ideal choice for most applications, from private homes and saunas to commercial premises. A key advantage of the system is its flexibility: you can choose the outer casing from classic stainless steel, practical galvanized steel, or order an elegant powder coating in any RAL color.
NordicPipe Premium System
NordicPipe is our flagship series, designed for projects with the highest aesthetic requirements. Its key features are a perfectly smooth outer casing with a welded seam and a durable black matte powder coating, which makes the chimney a full-fledged element of interior design. For maximum longevity, the inner flue pipe can also be made from thicker steel (up to 1.0 mm).
Key Advantages of Both Systems
- Exceptional Fire Safety: A dense layer of non-combustible basalt wool (100 kg/m³) with a thickness of 50 mm effectively reduces the temperature of the chimney's outer surface. This is a key factor for safe passage through wooden walls, floors, and roofs.
- Stable Heating Performance: Thanks to high-quality insulation, the inner pipe heats up quickly and maintains a high temperature for the flue gases along the entire channel. This ensures stable draft and helps heating appliances (boilers, fireplaces, stoves) operate with maximum efficiency.
- Condensate and Soot Protection: The rapid heating of the inner pipe allows it to quickly pass the "dew point," which minimizes the formation of aggressive condensate and soot. As a result, the chimney lasts longer and requires less frequent maintenance.
- Versatility and Compatibility: Both systems are suitable for all types of heating appliances that run on wood, gas, coal, pellets, or diesel fuel.
- Durability and Warranty: We use only acid-resistant and heat-resistant stainless steel grades AISI 316L and AISI 304. Both systems come with an official 10-year warranty.
- Photos from Real Projects: See how our chimneys look in real life in our photo gallery.
- EU Standard Certification: Full compliance with the European safety standard EN 1856-1, confirmed by CE marking. Learn more about our quality guarantees.

Frequently Asked Questions (FAQ)
Both systems have the same internal construction and safety level. The key difference is in their external appearance and finish:
- IZOKOMPAKT is a versatile system with a flexible choice of outer casing (stainless steel, galvanized steel, or any RAL color).
- NordicPipe is a premium, design-focused system. Its outer casing has a perfectly smooth welded seam and is covered with a durable black matte powder coating, making it a part of modern interior design.
The main advantage is maximum fire safety and versatility. Unlike single-wall pipes, an insulated chimney is a fully self-contained and ready-to-use twin-wall chimney system that can be safely run through wooden floors and installed where there was no flue channel initially.
The basic rule is that the internal diameter of the chimney should not be smaller than the diameter of the outlet pipe of the boiler, stove, or fireplace. If you are in doubt, our specialists can help perform an accurate calculation to ensure stable draft and safe operation.
We are confident in the quality of our products and provide a 10-year manufacturer's warranty on all components of the IZOKOMPAKT and NordicPipe systems. The estimated service life of a sandwich chimney is over 20 years, provided it is properly installed and maintained.
