Röben Darwin LDF Red and Brown Smooth Clinker Brick

Red clinker brick with brown shading. It was created for investors who appreciate traditional red brick, but they are looking for a color variant that will bring a breath of freshness to the building’s appearance.

The Darwin shade is particularly suited to projects combining tradition and modernity. Used in interior architecture, it will create an original atmosphere, and thanks to its strength and fire resistance it is also a good material for surface finishing, which is susceptible to damage.

Main characteristics:

1. The smooth surface of the face and heterogeneous coloring
2. Perfect for projects combining tradition and modernity
3. High technical parameters of bricks
4. Extended LDF format (290 x 115 x 52 mm)
