Clay or concrete tiles?

It is a question often raised by customers who are facing the choice to use Clay tiles or Concrete tiles. MONIER operates both clay tile factories and concrete tile factories and we are convinced each product has its own benefits.

In India, few investments have been done in the clay tile industry recently and the quality of the average clay tiles does not reach the usual international standard of this industry. At MONIER, we have invested in the latest available technology in Bangalore to produce a high quality concrete tile and in Calicut for the glazing process of our clay tiles.

Here is a quick benchmark we present you, based on our knowledge of the Indian roof tile industry :
