Smooth red

Clinker brick with a traditional red color of baked clay - classic in brick construction and in the assortment of our company. Like other clinker bricks, it is durable, resistant to mechanical damage as well as durable.

It is an excellent material, among others, for facades of single-family houses, large urban projects (especially in the vicinity of stone monuments) and objects with post-industrial style. It has been applied in many important projects, such as shopping centers (e.g. Focus Park Mall in Bydgoszcz, Gala in Lublin), waterworks (e.g. Water Treatment Facility for the city of Wrocław at Na Grobli Street, Building of Intermediate Ozone and Carbon Filters MPWiK in Warsaw) and hotels (including Fahrenheit in Gdańsk, Blue Diamond in Rzeszów).

  1. Classic color
  2. Used in many large projects
  3. Excellent technical parameters of bricks
  4. Resistant to mechanical damage
