UBLO, The world’s first
personalized ventilation window





UBLO is a circular window  installed directly into glass without linear operating frames. The title 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 Dutch architect and Co-founder of VS-A façade engineering group Robert-Jan van SANTEN.
