The KeraTwin rear ventilated curtain wall Facade System gives designers, engineers, architects, and developers practically unlimited aesthetic and industrial versatility and massive design freedom. The high-quality Stoneware Ceramic Panels are available in a wide variety of surface colours, formats, and profiles. 

Keratwin Comes in Both Glazed and Unglazed Terracotta Finishes

KeraTwin offers over 100 different colour choices, including a range of glazed stain matt, gloss colours, unglazed colours, concrete, stone, metallic, and timber finishes. The Natura series resembles the classic colours of the terracotta panels but is a more durable and maintenance-free ceramic stoneware material. 

The KeraTwin terracotta collection is perfect for those who want to achieve the terracotta finish without the disadvantage of a terracotta panel (terracotta absorbs water making it denser).

The Design Unglazed series completes the unglazed options across the range. It is a specially manufactured set of 4-panel colours with a slightly heavier surface texture.

Hydrotect: The Revolutionary Surface Coating

One of the most urgent responsibilities we have today is environmental protection, and Agrob Buchtal, the manufacturer of KeraTwin, feels the need to contribute to this call as much as they can, hence hydrotect was created. Hydrotect is a ceramic facade coating that offers three key environmental and economical advantages: 

  • It is remarkably easy to clean/self-washing effect that guarantees to last a long time.
  • It has an antibacterial property without the need for chemical products.*
  • Exhaust fumes produced by cars and industry are decomposed: 1,000 m² of the facade ceramics with TiO produce the same results as 70 medium-sized transitory trees.
