The idea of this circular ventilation window was initiated in 2017
by the founder of VS-A façade engineering group Robert-Jan
van SANTEN. Soon, Ublo.Inc was established in Korea with Naree Kim in 2018. Ublo, natural ventilation window series have developed through R&D of Ublo Inc. and VS-A Group
Ublo derives from the word hublot, or the round window of ships and airplanes.
The idea of this circular ventilation window was initiated in 2017 by
Director Robert-Jan, the founder of the VS-A Group. This is a round window
installed into glass, different from the existing window market where frames
become thicker as performance develops. The larger the glass in which Ublo
windows are installed, the more efficient the cost and ventilation are in
comparison to existing windows.
Ublo 3.0 opening is standardized to be the ideal size safe for the human
body’s proportions. The circular opening, or the wind passage, is designed and
positioned on the glass to the users’ tastes. Ublo covers can become customized
objects floating on the glass window to suit the interior atmosphere.
