Windows, from a functional point of view, are elements that provides us with lighting and ventilation, but what do they contribute to us at the design level?The material, whether wood, PVC or aluminum, will influence the decoration. The way in which the windows are opened also offers different ambience. Size, on the other hand, is a characteristic that must be taken into account. The large windows offer sensations that open us to the outside but the smaller windows transmit warmth and intimacy. The secret is to adapt each material, size and shape of the window to the space it occupies, use the best materials and that the installation is completely correct.
