Casement windows open by rotating horizontally to the left and right from the center, taking either the left or right edge as an axis. Some open into the interior, while others open onto the exterior. Both the left and right panels have the same dimensions: those that only open in one direction are called kannon-biraki (“goddess of mercy”), while those where one side is larger than the other are called oyako-biraki (“parent-and-child”). The ones opening in only one direction used in France since the 16th century are known as French windows.
Index of Window Sounds and Movements
For this project, we sought to extract and observe the sounds and movements associated with the opening and closing of windows, in order to shed more light on how we perceive a
“window” through our ears and eyes. A Glossary of Window Sounds and Movements is the first research project of “Windows Products Inside,” carried out as a collaboration between the Window Research Institute and product designer Yoh Komiyama, with video imagery created by Tomohiro Okazaki.
