Coming soon: The Exploded View Beyond Building

Kerloc facade tiles

Martens keramiek b.v.

Kerloc is a cold ceramic material that is produced without any additional heating. The material is made of residual materials (Such as natural fibers coming from agriculture, horticulture and / or forestry), minerals and fertilizers. Kerloc is used in the outer shell of a building as facade panels and is 100% circular: it is fully reusable in its own production process.

Cold ground ceramics

The Kerloc facade tiles are made of:

  • Natural fibers coming from residual plant materials from agriculture, horticulture and forestry
  • Natural minerals
  • Fertilizers

Production process

  • The residual materials are processed into the right size. The raw materials are mixed in several steps until a homogeneous and usable mixture is obtained.
  • This ceramic sheet material is produced at normal temperatures through an exothermic reaction: no additional heating is necessary during this process, ensuring low energy consumption.
  • The fiber materials are petrified during this process.


Kerloc is applied in the outer shell of a building as facade tile

Environmental impact

  • Raw materials are locally sourced as much as possible: most come from The Netherlands or adjacent countries
  • All raw materials come from natural (residual) flows
  • Kerloc tiles have a long lifespan (over 50 years) and are therefore suited for reassembling
  • Fully recyclable in its own production process

Growth opportunities

Parties have a conservative attitude. The material does not yet have a proven track record and certifications, which is why some parties are taking a wait-and-see approach.
