PORRATH lightweight refractory bricks are porous bricks with low thermal conductivity and excellent hot properties, covering the complete range of applications from 1200°C bis 1800°C. The chemical and physical properties of PORRATH bricks make it possible to optimally meet a wide variety of requirements.

Depending on the area of application and process temperature, RATH lightweight refractory bricks are made of various raw materials and can be manufactured with very small dimensional tolerances in complex shapes.
