POSTAER SANDSTONE -Bh-

POSTAER SANDSTEIN -Bh- (sculpting material) is a medium-grained, silica-bound Elbe sandstone of selected gray to yellowish-brown color and texture. It is as free as possible from inclusions.

POSTAER SANDSTONE is absolutely frost and weather resistant and due to its special hardness and environmental resistance it is used especially for demanding, highly stressed and splash water endangered architectural parts. Due to its special and flawless appearance, it is mainly used in exclusive villa construction - exterior as well as interior. For example, load-bearing columns, floor slabs, profiled steps and balustrades in the foyers of castles, villas and stately homes are among the preferred applications for this material.
