The BE-25 is a modern aluminum system designed for external terrace and balcony constructions. A characteristic feature of the system is the ability to move the leaves in both directions on a four-track guide and set them "one behind the other", which gives us maximum open space. The tightness of the construction is ensured by properly designed vertical profiles of the window leaves, which allow for hooking the adjacent windows together while they are being extended. The system is sealed and protected against weather conditions by seals.
The BE-25 system is dedicated to enclosure spaces that do not require heating. The constructions are ideal for the implementation of entire buildings, as well as individual rooms.
