Windsor Light Grey Flagstone

These impressive Windsor grey flagstones make a simple yet elegant statement. Each individual tile has been softly tumbled to create a gently worn look, reminiscent of a centuries old floor. This aging process gives an almost slate like finish to this limestone creating a floor of timeless beauty enhanced by the shimmering quartz fleck abundant in this natural stone. The grey colour palette is quite unique with very soft greys, very pale green-greys through to a taupey almost pale purple-grey. Windsor limestones flags are extremely versatile and hard-wearing. Use indoors and outdoors for a truly seamless look that blends house and garden. Large in format, they come in mixed lengths up to 90 cm long, so each floor will be completely unique.
