Kafka Starlight Black Granite Irregular Thermal Flagstone

A Premium, Natural Stone Alternative

Kafka Granite’s Thermal Flagstone provides a premium natural stone alternative to manufactured hardscapes. Available either as irregular-edged flagstone or as a repeating pattern of sawn flagstone, each stone has a sawn height with 1/2″ tolerance to cut down on sorting and installation time and virtually eliminate shimming and re-leveling.

Kafka Granite Thermal Flagstone is the perfect option for incorporating a sophisticated look into your hardscape project. Even better, the beauty of natural stone hardscapes now comes with enhanced performance: the top surface of each unit also has a thermal finish to provide additional traction and accentuate the unique character of the natural stone.


Kafka’s natural Thermal Flagstone has sawn tops and bottoms for a streamlined installation, virtually eliminating the need for shimming and re-leveling. These hardscapes will maintain their integrity for decades, and pair seamlessly with many of our other product lines.

Another advantage of working with Kafka is the ability to source your entire project from complementary categories of our natural stone products.

Frequently Asked Questions

Kafka’s Thermal Flagstone has a thermal finish. The process of creating this type of 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.

Traditional flagstone is typically rough on all sides, which requires extra care and time during the installation process. When developing Kafka’s natural stone hardscapes, we wanted to create a natural stone product line that stood apart from other options in terms of performance and ease of installation. To that end, our Thermal Flagstone is sawn on the top and bottom to streamline installation.

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 natural flagstone that is not sawn to height. The end result is a more efficient installation, a quicker setup process, and potentially a lower final project cost.

Natural stone is a high-end alternative to cultured or manufactured stone. At the same time, this beautiful material can actually save you money in the long run. Just consider the longevity of your project—manufactured stone and other cheaper materials will typically degrade and become discolored when exposed to the elements. Natural stone, on the other hand, wears beautifully, maintaining both its look and integrity in an outdoor installation. With Kafka Granite’s natural stone hardscapes, you can rest assured that your retaining wall, stone steps, or other landscaping project will continue to perform throughout the years.
