heroal rs hybrid in flush-mounting box FMB 90°

Perfect retention of existing façade appearance

Thanks to its invisible integration in the ETICS or in the window reveal, the flush-mounted box FMB 90° represents the ideal means of installing a heroal rs hybrid in the existing façade architecture without changing its visual appearance. A large selection of plaster base profiles ensures secure installation in all current ETICS systems, while the special two-part guide rail guarantees simple and safe assembly in the window reveal. The minimum thickness of the exterior insulation depends on the exact position of the window. Made from roll-formed and extruded aluminium profiles, the flushmounted box features a highly space-saving design with a height of just 125 mm. The 90 mm inspection opening enables simple and convenient system maintenance.
