The MET design innovation provides the complete blend of frame, door leaf and wall. With this revolutionary wall-fitting frame system Josko is also following the trend towards simple optics with its interior doors. The corner piece of the door system is a special aluminium frame which can be plastered or painted, thus becoming “invisible”. This effect is particularly attractive on smooth doors which are painted to tone in with the wall. And because perfection at Josko lines in the detail, even the doorknobs fit the design perfectly.
