Generally speaking, bay windows are mostly floor-to-ceiling windows or windows with low height. From the perspective of geomantic omen, such a large window will drain the geomantic omen of the house from the source, which is an unlucky architectural design. Even if there is window glass as isolation, it is only useless decoration.
Bay window itself is not solid insulation, installed in your bedroom, of course, beautiful, but not very easy to use; Optical isolation is also inconvenient. So to sum up, bay windows are not suitable for ordinary family houses in most cases, but they are especially suitable for high-rise buildings.
