The frameless fully opening balcony glazing system began to be used in Scandinavia and is rapidly gaining popularity in Lithuania. In balconies glazed with this principle, no vertical profiles are used between the glass, so the balcony looks aesthetic both from the inside and outside and does not spoil the facade side of the building. This gives the system an undeniable advantage. All moving glass parts are made using tempered glass, slide easily in one plane, and can open inward to the balcony like book pages. For these reasons, not only the operation of the frameless glazing system is convenient, but also maintenance – to clean the glass, it is enough to open them and perform cleaning work conveniently and safely. A balcony glazed this way can be opened 100 percent!!!
