Conclusion
We are now experiencing an unprecedented influx of highly innovative building materials and systems. Among them, ventilated glass façades with superior performance and unique daylighting capabilities are quickly becoming a preferred choice for building professionals. The sophistication and aesthetic appeal of these systems can easily elevate the appearance and prestige of buildings (new or old), right from parking structures and mass transit stations to luxury high-rises.
| A VENTILATED GLASS FACADE PROVIDES MULTIPLE BENEFITS |
| Performance It protects from the elements, provides passive ventilation, and offers fire safety through the use of non-combustible system components. A glass rainscreen assembly can also improve the façade’s thermal insulation properties through the addition of either rigid insulation or insulated metal panels (IMPs) behind the glass cladding. Colors, frits, decorative interlayers, and digital patterns and designs on the glass provide improved shading and solar radiation control. Even monolithic, ultra-clear (low-iron) glass blocks more than 10 percent of solar energy and 15 percent of ultraviolet (UV) energy. In laminated form, the glass can block over 99 percent of UV radiation, protecting materials behind the cladding layer against fading and discoloration.Aesthetics Transforms and elevates the building’s appearance, and the nonporous, low-maintenance glass surfaces require minimal effort for upkeep.Daylighting and visibility It preserves daylighting advantages and views through the use of transparent or translucent decorative glass cladding over openings. The material allows occupants to see and be seen for added safety and comfort, and reduces energy costs by reducing the need for artificial interior lighting.Durability Ventilated glass façades withstand punishing climates and environments better than porous façade materials, and resist permanent staining, fading, and corrosion.
