Roben Portland Anthracite Smooth Clinker Brick

Röben Portland Anthracite Smooth Clinker Brick

Röben Portland Anthracite Smooth Clinker Brick is distinguished by its smooth face surface and muted black tone, achieved through engobing. It complements modern buildings and minimalist designs, while also inspiring creative use in other architectural styles. This brick is also an excellent material for clinker chimneys, especially when paired with dark roof coverings such as black or grey. Like all Röben bricks, it is characterised by longevity, durability, and resistance to external factors including water, frost, wind, and fire.
