glazing: The Latest Architecture and News

When we talk about the building envelope, we often make the analogy of a skin that protects and wraps the structure, creating a transition in the physical environment. This concept is interesting as it identifies that, similar to its function in humans, the skin plays a role in protecting and regulating the interior setting, besides contributing to the aesthetics of the building. In this way, both the human skin and the building envelope act as elements that respond to the stimuli of the surroundings and the life that develops within them. More than just protective barriers, they are experienced as means of active interaction with the context.

While envelopes evolve within diverse contexts, materials, and systems, minimalist windows distinguish themselves through their aesthetic qualities by being transparent and fluid skins. These windows excel with their functionality and visual lightness, standing out in the architectural landscape. In addition, they are noteworthy thanks to their versatility across different systems that connect life within the interior and exterior. Considering Swiss and Pritzker Prize-winning architect Peter Zumthor's statement that "architecture is exposed to life,” windows play a vital role in expressing that connection, becoming a significant part of the building's identity and essence.

In the context of WWI and to address the massive housing shortage resulting from the conflict, the Dom-Ino modular structure, one of the most significant contributions of functionalism and designed by the Swiss designers Le Corbusier and Max Dubois, established concrete premises for a new vision of a lightweight structural model that optimizes the construction process. Thanks to the use of a reinforced concrete slab and column system, the Dom-Ino structure allowed for the flexible arrangement of elements in the floor plan and freed the facade from the limitations imposed by load-bearing walls.

This condition prompted the creation of architectural designs that not only integrated windows as functional elements but also as compositional. Thanks to technological innovations, windows with slender framings and wider openings were achieved, as exemplified in works such as Villa Savoye and Farnsworth House. While these proposals redefined the aesthetics of architecture, the technological limitations of the time presented challenges. Nowadays, the continuous development of windows with improved technical characteristics has led to the concept of the minimalist window, which has inspired three fundamental principles derived from this concept, conceived by Vitrocsa. These principles —transparency, functional variations, and advanced mechanisms— incorporate technological innovations while simultaneously blurring spatial boundaries. Each of them plays a key role in the design of spaces and together they significantly redefine the aesthetics of buildings and interiors.

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.

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.
