Every brick wall should be covered or protected from rainwater or snow. Wall crowns can be made from roof tiles, from sheet metal or from glazed, hard-fired clinker bricks. Special shaped clay bricks for wall coverings are always shaped with slopes or curves. Beveled or rounded edges allow water to drain quickly. Bricks for wall cover should be particularly durable. That’s why our customer decided on hard-fired, brown salt glazed clinker bricks. Salt glazed surface is waterproof and extreme durable.
