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:
Ergoldsbacher E 58 RS roof tile offers protection against driving rain from an angle of 10°. In cooperation with ERLUS, an innovative water supply system has been developed for this purpose, which eliminates the need for complex additional rain-protection measures for the substructure of the roof. This includes the triple head and side fold as well as particularly high webs.
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 (water flow, four-brick corner, stacking points, ribbing, sliding paths) 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.
