We have succeeded in designing the most beautiful window with a floating mullion. We have named it bluVISIO, and its central module is only 14 cm thick. Small glazing in comparison to the whole construction and an unhandy lever - these factors have always discouraged purchases of windows with a floating mullion. Now, such factors are finally irrelevant. Top-quality fittings in the form of modern, curved handles improve the
window's ergonomics, which translates to easy operation.
