The A81 series is an innovative shutter making system, which brings the essence of the old wooden shutter to modern aluminium constructions. Its design combines technological excellence with classic aesthetic perfection and provides all the features for a shutter construction of timeless value.


The system has the appropriate infrastructure for installing a window net. It is possible to build a shutter for all construction types. A special additional profile for the frame allows the folding and securing of the sheets vertically inside the masonry.
