When children first learn to draw a house, there are four basic components they illustrate: a wall, a pitched roof, a door and one or more windows. Along with the common structural elements, windows have always been considered to be indispensable architectural features for their multiple functions. While providing views, daylight and natural ventilation, these insulate from cold and heat, protect from external threats and enhance a facade’s appearance. They are also associated with a strong poetic or symbolic value; it is through them that we are able to connect with and enjoy our surroundings, be it a beautiful natural landscape or a dense urban environment. An expressive part of any building, windows serve as a visual bridge between the inside and outside, acting somewhat as a refreshing escape from our everyday routine.
