Red and brown smooth

It is distinguished by its color - red with brown shading. It was created for investors who follow the tradition of building from red bricks, but they are looking for such color variants that will also bring a breath of freshness to the building’s appearance.

That’s why it will be especially useful in projects combining tradition and modernity. An interesting idea is to use it in projects reminiscent of industrial buildings - the red-brown facade will become a great complement to the raw, post-industrial solid. 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 finishing the space around the fireplace.
