For over a century, Theis-Böger has been dealing with construction activities using slate as a natural product. Construction styles and the various types of roofing are constantly changing. What has remained is the calming effect that a natural product such as slate has on people in our times.
It is our goal to bring the customer closer to the long-term benefits of natural stone in the roofing market. The wishes and needs of our partners are our first priority.
Ecology
Slate, quartzite and sandstone from Theis-Böger are pure natural products that contain no harmful substances. The low-energy mining and processing methods are environmentally friendly. And when these materials are finally disposed of after many generations, the ecological cycle is completed, as they simply return to nature.
Economic efficiency
The long life-span of our natural stone products in combination with their low purchasing costs results in a unique price-performance ratio.
Beauty and Individuality
Our slate comes in a great variety of different forms and natural colours to meet individual specifications. Whether you like it stylish or functionally modern, our natural stone products give each building a personal touch.
