Natural Stone-Veneer sheet is a Natural Product. Natural stone veneer is a unique technique which allows conserving the natural resources. Natural stone veneer made by a unique working process and by this process thin layers of natural stones approximately 0.5 to 2.0 mm are split from big, sized natural stone mostly from slate as it is a fine-grained, homogeneous, metamorphic rock derived from original shale-type sedimentary rock composed of clay or volcanic ash through low grade regional metamorphism. The result is a foliated rock in which the foliation may not correspond to the original sedimentary layering. Thickness of natural stone Veneer is approx. 1,0-2,5mm
