Röben Perth XLDF Brown Smooth Clinker Brick

Roben Perth XLDF Brown Smooth Clinker Brick is a high-quality clinker brick with a deep, rich brown shade. Its bold yet versatile colour makes it suitable for facades of single-family houses, public buildings, and landscaping elements such as benches, summerhouses, or garden grills. Dyed in mass, it ensures colour durability and allows cutting without revealing a different shade. It also offers excellent technical performance, including low absorbability, frost and fire resistance, and long-lasting durability.

Properties

• Remarkable and original brown coloration
