The collection is also available in a variety of plank widths. The combination of planks and the 30 x 60 and 60 x 60 centimeters tile sizes has prompted Mosa to advise nine laying patterns with this collection. The subtlety of the different shades in the Greys collection makes it possible to create a pattern that draws optimum attention to the combination of tile sizes. These Cradle to Cradle® Silver certified tiles are ideal for use in sustainable construction projects. Wear and scratch resistant quality and problem-free maintenance guarantee that the tiles will retain their appearance for a long time, even in the case of very intensive use.
