Thanks to its construction depth of 67mm for the Ecoline and 84mm for the Highline, this accordion bay system offers a low apparent width of 99 mm at the end of the leaf. This is due to the heart of the accordion bay, the bionicTURTLE®: a multifunctional insulating core that combines various technical details.
Its shape makes it possible to have extremely thin profiles, even in the presence of leaves of large dimensions and heavy weight. In addition, it accommodates the lock and fittings and guarantees optimum insulation.
