Gaia Coevo´s external windows and doors are made of Cortizo´s aluminum frames, one of the best window frames in Europe (https://www.cortizo.com). We chose the minimalist hidden frame, reducing the thickness of the aluminum frame and maximizing the glass area. The frames are white on the inside and gray on the outside. All windows and doors are tilt-turn, they can open inwards, which allows a thermo-acoustic seal much better than a sliding window, and they are tilting, it is able to open only the superior part.
