Switchable glass, also called smart glass, is a type of glass that can change its properties, such as transparency and colour, when voltage, light or heat is applied. This technology has gained popularity in recent years due to its many benefits. These include improved energy efficiency, more privacy and greater design flexibility.
Intelligent glass has the potential to revolutionise the way we interact with our environment. Imagine windows that can change from clear to opaque at the touch of a button, or walls that change colour depending on the time of day. However, as with any new technology, there are always questions about durability and longevity. Can switchable glass stand the test of time? Will it last forever? In this blog post, we address these questions and more.
The Lifespan of Switchable Glass
The lifespan of switchable glass depends on several factors, including the quality of the glass, the manufacturing process and the conditions under which the glass is used. According to a study by Cambridge University, tests with smart glass switched between opaque and transparent more than 27 million times, switching once a second for several years, promising a lifespan of decades. However, this lifespan can vary depending on the type of activity for which they were used. Switchable glass used in high traffic areas such as airports or shopping malls may have a shorter lifespan due to constant wear and tear. Similarly, switchable glass used in outdoor installations may be susceptible to weathering and sunlight.
Durability Depends on the Type of Activity for Which They Were Used
As mentioned earlier, the durability of switchable glass depends on the type of activity for which it was used. A study conducted by the National Institute of Standards and Technology (NIST) found that switchable glass used in laboratory environments such as clean rooms has a shorter lifespan due to the aggressive chemicals and cleaning agents used there. On the other hand, switchable glass used in residential or commercial buildings can last longer because it is not exposed to the same stress.
Solar Radiation
Solar radiation can also affect the durability of switchable glass. According to a study by the Fraunhofer Institute for Solar Energy Systems (ISE), switchable glass can lose up to 10% of its light transmission after 10 years of exposure to sunlight. This can be attributed to the deterioration of the electrochromic layer, which is responsible for the glass's ability to change colour. To mitigate this effect, manufacturers have developed new materials and coatings that can protect the electrochromic layer from sun damage.
The Use
The way the switchable glass is used can also affect its longevity. For example, a switchable glass that constantly changes from clear to opaque may wear more than a glass that is used in a solid state. Similarly, a switchable glass that is subjected to frequent load changes can put more stress on the electrochromic layer, which can lead to premature failure.
Maintenance
Proper maintenance is critical to the longevity of switchable glass. Regular cleaning and inspection can help identify problems before they develop into major issues. Switchable glass that is cleaned regularly can last up to 20 years, while glass that is not cleaned can fail after just a few years. In addition, manufacturers may offer warranties or maintenance plans that can help ensure the longevity of the glass.
Research on the Longevity of Switchable Glass
Several studies have been conducted on the durability of switchable glass. These studies have looked at factors such as sunlight exposure, use and maintenance and have provided valuable insights into the durability of this technology. However, further research is needed to fully understand the long-term impact of these factors on the durability of switchable glass.
Advances in the Technology of Switchable Glass
Like any other technology, switchable glass has made some advances in recent years. Manufacturers have developed new materials, coatings and manufacturing processes that can improve the durability and longevity of this technology. For example, some manufacturers have developed self-cleaning switchable glass that can reduce the need for regular maintenance. In addition, new materials and coatings can help protect the electrochromic layer from sun damage and other environmental effects.
Smart Glass is Safe and Durable
The durability and life of switchable glass depends on several factors, including the quality of the glass, the manufacturing process and the conditions under which the glass is used. Sun exposure, use and care are also important factors to consider. While research has provided valuable insight into the lifespan of switchable glass, more research is needed to fully understand the long-term impact of these factors.
