Transparency is now essential in commercial and residential construction, with many high-rise projects featuring vast glass expanses and curtain walls.
Fremont, CA: Humans have been working with glass for millennia, but it has become a luxury item for most of that period. It was not getting manufactured on a large scale until the 17th century when producers in England and Venice realized the advantages of lead in glassmaking. However, this mainly got confined to creating beautiful crystal glassware rather than glazing. Although the approach preceded the first noteworthy architectural projects utilizing big panel glazing by about two hundred years, lead glass became a vital stepping stone technology to using glass in architecture.
Transparency is now essential in commercial and residential construction, with many high-rise projects featuring vast glass expanses and curtain walls. Although glass is ubiquitous in a modern building, the underlying technologies are still the focus of research and development (R&D), intending to unlock new useful qualities from the material. Almost two hundred years have gone by since the industrialization of glazing, and new technologies are poised to disrupt the sector once more.
What is Architectural Glass Coating?
Architectural glass coatings are transparent layers put on the surface of glass panels to improve their thermal or optical qualities or enable some other advanced functionality. Changing the emissivity of glass in different settings is one of the underlying causes for the usage of architectural glass coatings. Glass rapidly allows heat to propagate, which may be an issue in maintaining appropriate ambient temperatures. It also has financial and environmental implications since heat escapes through the glass during the chilly winter months. Heat loss via windows alone costs the United States 40 billion dollars each year.
The first architectural glass treatments were created to reduce emissivity and retain heat inside or outside as needed. It is known as low emissivity (Low-E) glass, which uses a clear, architectural glass coating designed to reflect short- or long-wave radiation to reduce the amount of ultraviolet (UV) or infrared (IR) light that may pass through. The heat from the sun gets reflected out, while the heat from within gets reflected in. It is comparable to the technique used in lasers with internal mirrors.
