Thornbury is similar to Beacon Hill Flagstone in its resemblance to natural cut stone, but is more dramatic in its surface texture and smaller in scale. A larger joint space between units adds to a more rugged look and allows for traditional or permeable installations, making it ideal for managing water runoff. Thornbury is a popular choice for driveways as its scale makes it capable of handling vehicular loads, and its permeability can significantly reduce puddling and ice build up in winter.
