Evolve Stone is the first stone cladding that can be face nailed in the same fashion as traditional siding, reducing installation complexity and time dramatically. Like real stone, it is colored throughout, allowing it to be cut to fit on-site while maintaining the highest appearance standards. The ease and workability of the product is unprecedented. No specialty tools and training are needed to install Evolve Stone. Easily manipulate, cut, and texture the product with your standard woodworking tools. This stone is lightweight, at just 2 lbs. per square foot, but extremely durable, standing up to impossible wind speeds, salt spray, UV exposure, and freeze-thaw cycles. Each box is pre-portioned with engineered shapes allowing the pattern to appear naturally as you install. No need to sort and lay out the stones beforehand. We offer a class B fire rated product in each style and color. Coverage: Flats (loose stones) cover 14.25 sq. ft.; Sills cover 25 lin. ft.
