Ehret adorns the Kesselhaus in Leverkusen with a custom-designed contemporary facade

As part of the rehabilitation of this historic site in Munich, EHRET supplied 228 folding sliding shutter panels configured from its standard catalogue.

Custom-configured shutters from the EHRET standard catalog

The folding sliding shutters open at 90° to the facade and fit snugly against the building envelope when closed. "Thanks to our standard range, we were able to configure 228 panels with Matrico expanded metal infill, the SL 12 profile system and the necessary accessories, all from the EHRET catalog," says Klaus Wipfler, Sales Director for Germany.

The range of available references also allowed for a precise color match with Corten steel. The powder coating with a "rust – brown patina" effect recreates the appearance of aged metal, virtually indistinguishable from real oxidation.

Only the ground floor grating, sized for accessibility, required a specific drainage detail: the large elements are connected to the network, while the smaller ones flow away by direct infiltration.

For Klaus Wipfler: « This project perfectly illustrates the harmony between function, design, and material concept. The folding sliding shutters not only provide sun protection but also become a striking architectural element in themselves. »

Through this project, EHRET demonstrates its ability to combine heritage preservation, industrial precision, and architectural expression. By utilizing solutions from its standard catalog (SL 12 profiles, accessories, Matrico expanded metal infill) and appropriate finishes (Corten patina powder coating), the brand delivers a coherent, high-performance, and durable facade, perfectly integrated with the historic building and the contemporary extension.

Furthermore, the folding sliding shutter transcends its function of sun protection: it becomes a design element, contributing to user comfort and a distinctive architectural aesthetic. EHRET thus confirms its role as a leading partner for projects where context, technology, and design must interact with equal rigor.
