A black-toned Onyx option is the latest introduction to the NovikStone Dry Stack Stone and Premium Hand-Cut lines. The manufacturer says Dry Stack stone siding offers the detail of precision-laid dry-stack stone and helps achieve the look of traditional masonry, while Premium Hand-Cut siding mimics the look of hand-chiseled stone. The stone siding is impervious to moisture and resistant to warping, expansion, contraction, and cracking, according to the manufacturer. The siding is suited for foundation covers and knee-wall cladding and can be installed without mortar or adhesives. novik.com
