Harmonica system Harmonia

A system of aluminium sections with a thermal break designed for external applications. It enables constructing sliding concertina doors. The three-chamber sections with a frame depth of 72 mm provide the optimal thermal insulation. The concertina door system enables making large-size glazing and, at the same time, optimizing the occupied space after opening. Available in a version with a low doorstep as a convenience to the disabled. The system was tested when constructing partitions in single-family houses and commercial facilities.
