Imagine a roof that combines the nobility of historic architecture with cutting-edge solar technology. This is the eTile Karo system — an innovative solution created in cooperation with Rheinzink, one of the most renowned German titanium-zinc manufacturers with a tradition dating back to the 19th century. Let's see what makes it a unique solution for the most demanding architectural projects.

The essence of the eTile Karo system

The eTile Karo system is no ordinary solar roof. It is a precisely designed system that pays homage to traditional architecture, using the highest quality materials. Elements made of titanium-zinc from Rheinzink guarantee not only durability, but above all the prestige of the solution. In place of the classic rhombuses, you will now find integrated photovoltaic modules that maintain the characteristic pattern, adding new functionality to it.

Why choose the eTile Karo system?

If you own a historic townhouse or are planning to build a house inspired by historic architecture, the eTile Karo system may be exactly what you are looking for. This roofing system is distinguished by several key advantages.

First of all, titanium-zinc Rheinzink is a material with proven durability and exceptional resistance to mechanical damage. Unlike many other roofing materials, it does not require painting or special maintenance for the entire service life. Moreover, the natural patina that forms on the surface not only protects the material, but also gives it a noble appearance that goes well with both traditional materials such as wood or sandstone, as well as with modern glass or steel.

Technical aspects of the system

The eTile Karo system is designed to optimize weight while maintaining the highest technical parameters. Inactive parts weigh only 6.5 kg/m², while active parts with photovoltaic modules - 15 kg/m². It is still a relatively light solution, especially compared to traditional ceramic coverings, which is important when renovating older buildings.

The eTile Karo system shells have specially designed upper and lower bends in the form of flat edges. This is a key feature, inherited from Rheinzink's many years of experience, which distinguishes them from ordinary slabs or shingles of similar shape. Thanks to these bends, the system not only retains full tightness, but also allows you to safely perform both simple slopes and complex curvatures with a slope of as little as 35 degrees.

Integration with gutter system

One of the most innovative elements of the eTile Karo system is the possibility of using a hidden gutter system. This solution, using Rheinzink components, allows you to maintain a clean, uninterrupted roofline. The system is designed so that horizontal elements are covered with a special grille, and vertical elements can be elegantly hidden in the facade layer.

Universal use

What is particularly interesting is that the eTile Karo system works not only as a roofing material. You can also use it successfully as a facade system. In this case, you get a consistent, expressive finish of different parts of the building, using the same system. It is not only a matter of aesthetics - this solution also simplifies the process of assembly and subsequent servicing.

Assembly process and maintenance

The eTile Karo system is designed for ease of installation. It uses a proven fastening system, familiar to roofers working with traditional Rheinzink coverings. Moreover, the self-cleaning patina significantly reduces maintenance needs. In practice, this means that apart from standard inspections of the photovoltaic installation, the system does not require special attention.

Summary: Who is eTile Karo for?

The eTile Karo system is ideal for:

  • owners of historic tenement houses planning modernization with preservation of the historical character of the building
  • investors looking for prestigious, design solutions for modern buildings
  • projects requiring consistent finishing of the roof and facade
  • Buildings with complex roof geometry

If you are looking for a roofing system that combines the classic aesthetics of the German roofing school with modern energy solutions, eTile Karo may be exactly what you need.
