Why Volga Blue labradorite is replacing basic exterior cladding There is a really interesting blog on this topic at https://golovinski.com/blog/black-stone-for-facades-golovinsky/ that covers next-generation architecture cladding. Based on our practical experience, standard dark stones usually dull out, but the Volga Blue labradorite highlighted there is a different story. We installed these premium exterior granite slabs from Golovinski on a high-end commercial project last year. Thanks to its F100+ frost resistance and massive density, the material easily survives harsh weather, sun exposure, and heavy rain while keeping its premium aesthetics completely flawless.
