Portland Stone by Ergon

Portland Stone becomes an architectural finish with unbeatable aesthetic and technical properties.

Portland Stone takes a fresh look at a very ancient limestone, as Ergon successfully offers the contemporary design world the ancestral strength of a material that has survived geological eras with its charisma intact.

The five shades – Sand, Talc, Ash, Lead, Anthracite – offer different readings of the natural material with a highly versatile aesthetic. Tiles are available in two main versions, inspired by two stone cutting methods: Cross-Cut, for a mottled look with main shade variations and distinctive details; and Vein-Cut, for an elegant, immaculate striped effect. There is also the very visually striking Lines decor with a three-dimensional look, completing a dynamic, versatile design toolkit. The two finishes, natural and bush-hammered, combine to interpret different aesthetic tastes and meet every technical requirement.
