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.
glazing: The Latest Architecture and News
Windows serve multiple essential functions in any project, from framing views to providing daylight and natural ventilation. As human needs have shifted and technology has advanced significantly throughout the years, these have evolved in character, shape, and use of materials. What began as small arrow loops used for defense in medieval fortifications later transformed into wider openings that exemplified status and wealth. The Romans were the first to use glass, but it was considered a precious commodity for centuries. Intricate stained-glass panels adorned countless of medieval churches and cathedrals, while most home dwellers had to settle for covering their “windows” with wood, fur and other materials.
The total energy demand from buildings has risen dramatically in recent years. Driven by improved access in developing countries, greater ownership of energy-consuming devices and increasing urban densities, today it accounts for over one-third of global energy consumption and nearly 15% of direct CO2 emissions. As the climate crisis aggravates and its consequences are more visible than ever, the architecture and construction industry must respond accordingly. It must take responsibility for its environmental impact and give priority to reducing energy consumption, whether through design decisions, construction techniques or innovative products. The key lies, however, in not sacrificing aesthetics and comfort in the process.
Like a beautiful painting, windows showcase interiors and frame landscapes that connect users to the outside world, directing our eyes to what really matters. But besides framing views and facilitating visual communication, windows serve multiple essential functions that make them vital components in any project. They illuminate homes with sunrays, provide natural ventilation, filter light, insulate from cold and heat, block water and ensure protection. As most design professionals would agree, glazing also plays a crucial aesthetic role; its materials, style and dimensions certainly make a significant difference in the appearance of facades and spaces.
Glazing has always been employed in architecture to convey and complement aesthetics. Its use exemplifies spaces, transitions between indoor and outdoor volumes, and modulates the amount of light penetration. With this in mind, glazing manufacturers are continually innovating new products to resolve the ever increasing demands imposed by designers. Whether it is curvilinear, textured, colored, laminated, etc., the increasing variety available is growing at an increasing rate.
