Frequently Asked Questions

The process of creating a thermal finish involves exposing the wet surface of a stone to intense heat. This results in a skid and slip-resistant surface, perfect for commercial or residential landscaping projects. The high temperature also serves to further reveal the unique look of each natural stone product.

Typical outcropping stone is rough on all sides, which requires extra time and effort during installation. When developing Kafka Granite’s Natural Stone Hardscapes, such as Thermal Flagstone, we wanted to create a natural stone product line that performs better and installs more easily. Our Thermal Flagstone is sawn on the top and bottom, streamlining the installation process. While professional installation is still necessary, it will proceed more quickly and smoothly than it would with traditional outcropping stone.

Our Thermal Flagstone is sawn to height, which effectively eliminates the need for shimming and re-leveling during installation. This provides a significant advantage over other natural stone products with uneven surfaces. The end result is a quicker setup process and more efficient installation, with the potential for a lower final project cost.

Natural stone is a high-end alternative to cultured or manufactured stone. Despite its higher price point, our natural flagstone — along with other natural stone hardscapes — offers superior value in the long run. Just consider the longevity of your project — manufactured stone and other cheaper materials tend to degrade and discolor after repeated exposure to the elements. Natural stone, on the other hand, wears beautifully, maintaining its look and integrity in nearly any environment.

Make the choice you’ll feel good about for years to come. Turn to Kafka Granite’s natural stone hardscapes for your next retaining wall, stone steps, or other landscaping projects.
