The frameless window system are placed on one or both sides of the balcony or terrace and opened by folding them parallel to the inner side of the wall. This way the room is fully open. Depending on the height of the structure, we use tempered glass of 8, 10 mm of thickness. There is a gap of 3-4 mm between the glasses, which allows air to circulate even when the balcony is closed, preventing misting of windows.
The frameless window system is more expensive, yet more aesthetically attractive. It works best when you want to preserve the image beyond the window, a beautiful natural scenery.
