Sliding window systems is another solution for the balcony window opening. It is a system which is very popular in south-european countries. In the sliding windows systmes the sashes can be moved in the parallel planes in respect to each other. For sealing of sashes brush seals are used. This is not only interesting, but very convenient solution, especially for those who like big, glazed surfaces. The additional advantage is the fact, that the windows do not take space after being opened.

Above shown, the pictures of the three available system solutions within the sliding windows systems:

First: Dual-rail (60mm) - glazing up to 19 mm

Second: Multi-sliding - glazing to 33 mm, featuring the possibility of adding another parallel tracks. Several wings, placed on separate tracks after opening slide independently of each other, revealing a large openings. Useful also for the construction of doors.

Third: Mono-rail - only a single pane glazing, a fixed-glazing casement located directly in the frame, without the need to install the fixed sash.
