The mosque combines modernity and authentic design Ductal® was chosen for the facades around the minaret, the roofing of the dome of the prayer hall, the inner courtyard and the covering of the other buildings.

This architectural masterpiece was designed by Krebs und Kiefer and managed by Anargema (the agency under Algeria’s Ministry of Housing which is responsible for construction and management of the mosque) and built by CSCEC. Its successful execution depended on high-quality materials - especially for the facades.

Description

The roof of the prayer hall of the Great Mosque of Algeria (Djamaa el Djazaïr) rises to a height of 45 meters. The dome it supports is 50 meters wide and 25 meters tall. Not far from this dome the highest minaret in the world towers at a height of 265 meters, containing 43 floors served by panoramic elevators. With a built area of 400,000 m² and more than 23,000 m² of Ductal® facades, our materials help bring an architectural masterpiece to life

Challenge

The minaret facades employ an element of traditional Arabic architecture called mashrabiya that has been used since the Middle Ages. Mashrabiya involves intricate latticework, and its motif both respects Islamic traditions and lends a unique identity to the mosque. These complex patterns require a delicate touch in both design and manufacturing: the mashrabiya could weigh no more than 65 kg/m²

Aesthetics

Thanks to Ductal® Spray solution, it was possible to design very thin panels without passive reinforcement that also met the artist's expectations. Beyond the aesthetic constraint of the design, Ductal® assures the durability of the brise-soleil even when installed several hundred meters high, where it can be exposed to intense winds and sea salt spray in an area with high seismic activity.
