How good air can ventilate the room is determined by air pressure difference rather than the window opening size. By examining the relevant conditions, the location and quantity of UBLO openings can be decided in order to achive an optimal situation for the best results.
There is no bisecting frame blocking the full view as other operating windows do. Ublos can ensure a panoramic view while still allowing fresh breezes.
The small size of each Ublo opening ensures safety from potential falling hazards, especially in high-rise buildings.
Risk of falls is eliminated
Outsiders cannot trespass through the window
Protection from extreme weather conditions such as typhoons
