For the Rynkevang School in Kalundborg Art Andersen produced 13 big movable shutter frames positioned in 2 levels. The shutter frames are made of galvanized and perforated expanded metal, and they can be operated manually from inside.

The shutter frames screen from the sun and the light – and give a pleasant indoor climate. Yet they also allow outlook for the pupils and the teachers, even when they are totally closed.
