Weight optimization of a roofing tile based on FEM calculations

After the successful revamp of the Alegra 12 (formerly FD) flat tile and its accessories, the flagship model in the Wienerberger product range in Holland, it was the turn of OVH tile to undergo a restyling. Reaffirming its confidence in Bongioanni, Wienerberger continued the collaboration between the two companies.

The usual optimizations included improved tiling comfort thanks to an increase in the interlocking clearance and higher strength, without, however, changing the aesthetics of this historical tile. The decision was taken to perform a specific study to reduce the weight of the tile to the minimum allowed.

The consequences of this reduction are well-known: lower clay consumption, lower energy consumption for drying and firing, reduction of the pallet weight and the roof weight per m² in the roof covering.

Following modelling of the roofing tile, the tile structures were examined based on FEM calculations to determine the best solution. This not only enabled an improvement of the mechanical strength compared to the previous model, but a substantial reduction of the weight per m² too.
