Technical Information

Technical Characteristics:

Stone Type Solnhofen Slabs:
limestone with a very high density and homogeneity


  • floor coverings
  • wall coverings
  • staircases
  • window sills
  • hygienic work surfaces
  • gardens
  • walls and paths (because they can be walked and driven on!)
  • indoor (bathrooms, showers, saunas and hygienic work surfaces in kitchens!)
  • outdoor areas in private and public spaces
  • also ideally suited for individual artistic design!

Basic Applications:

  • light- and colour-fast
  • step-resistant and non-slip R13 (thanks to its natural split rough surface)
  • very abrasion resistant
  • extremely hard-wearing (therefore ideally suited for both private and public areas)
  • simple and inexpensive care only with water and/or green soap

Building Biological Properties:

  • excellent building biology properties, 100% radiation-free! (in contrast to some granites and slates!)
  • no evaporation (fogging) like some artificial stones!
  • the nature makes the difference!

Colours: warm colours in the natural interplay of light cream over yellow, beige, light brown to gray

Chemical Composition: ca. 98% CaCO3, ca. 0.5 to 2% MgCO3

Gross Weight:                   2.55 kg / dm ³

Compressive Strength:  215 N / mm ² (according to DIN 52105)

Flexural Strength:          28.6 N / mm ²

Thermal Conductivity:  2.3 W / m × K

Water Absorption:         1.4% by weight

Surface:                             natural split rough R13
Regulation:                       inside at least R9, outside at least R11

for laying in a thick, medium or thin bed, depending on the panel thickness and substrate, panels are delivered in the tolerance grading of your choice, given by nature. The height adjustment takes place in the mortar bed. Please note the installation instructions!

Underfloor heating:
Solnhofen Natural Stone is very suitable as a covering over underfloor heating due to its high density and homogeneity.

Frost resistance:
in the case of limestones, perfect frost resistance cannot be guaranteed, but thanks to the asymmetry of polygonal slabs, it does not matter optically.

Please note that these are natural products that may differ in their colour, shape and texture from the representation. Colour and the structure fluctuations are given by nature. They can neither be influenced nor avoided and are within the colour shade and the stone structure are permissible according to DIN 18332. This also includes typical oxidations of iron-manganese containing inclusions (dendrites), which can lead to colour changes.
