Bonded boat windows are directly stuck into the vessels’ structure, meaning that there is no frame. For aesthetic reasons and to protect the adhesive material from UV degradation, the edge of the glass is screen-printed with a solid black band that is fired into the glass. As mentioned, an important benefit of this type of window is the sleek look. Another benefit is that the glazing can be cut in divergent shapes, allowing more design opportunities than a framed window.
