The first model of the successful Ergoldsbacher E58 family was created in 1958. In the following decades, four variants were added to the series. With them ERLUS reacted to new demands of the market.
The reason for the latest revision is the trend towards flat roof pitches:
Starting from a minimum roof pitch of 10°, Ergoldsbacher E 58 RS roof tiles offer protection against driving rain. In cooperation with ERLUS, an innovative water drainage system has been developed for this purpose. The marked profile of the interlocking joints on all sides with triple head and side locks and the direct water channelling ensure that the substructure stays dry. This means that no laborious extra measures are necessary to ensure raintightness.
The challenge in designing the youngest member of the E58 family was to highlight the typical optical features and at the same time sensitively modernize the appearance. The proportions have been slightly modified. Precise graphic contours form a contrast to the gently curved visible surface. Finally, the complex functional areas areas (water chanelling, four-brick corner, stacking points, ribbing, sliding and gauge ranges) should form a harmonious but exciting unity with the visible surface.
Important components of the work of speziell® were also the digitalisation of the development process, the mould making in the prototype stage and the digital preparation of the moulds with demoulding chamfers and crowning. Also the adaptation of the geometry to existing drying support and kiln furniture in the production was taken over.
