Solar control glass vs. low-emissivity glass for curtain walls
For curtain wall applications, selecting solar control glass optimizes energy efficiency in warm regions, whereas Low-E glass improves comfort and energy savings in cooler environments.
No, the BIPV photovoltaic glass structurally does not differ from other types of conventional glazing. Therefore, it is integrated into the building envelope (curtain wall, façade, or skylight) like any construction material. What solar control and comfort advantages does photovoltaic glass offer in a curtain wall?
They enhance thermal comfort and help prevent the greenhouse effect. A standard curtain wall offers no return on investment. In contrast, a photovoltaic curtain wall not only insulates the building but also generates power for over 30 years. This reduces monthly electricity bills and ultimately pays for itself over time.
There are 2 main categories of glass curtain wall if we look at their fabrication and installation methods: stick systems and unitized (or modular) systems. A frame is assembled on-site using mullions, transoms, and glass or opaque panels (potentially glass spandrels), which are designed to fit together as a unitized system.
The curtain wall glass is used in large uninterrupted areas, creating attractive looking facades where higher light transmission and lower reflection are desirable.
