Because parallel slide & tilt doors can be configured with up to four sashes, they can be used to create very large glass areas. However, it is not just the number of sashes that is decisive for the overall size of the door, but also whether the elements are fixed or movable. In principle, the individual sash can have different widths, but experience has shown that 80 to 100 cm is ideal, while a height of approx. 200 cm has proven to be the ideal size. The potential minimum and maximum sizes that can be used are shown in the configuration tool.
