The NSG Group is fast tracking its research into producing glass with an antiviral coating, as it looks to help specifiers find new ways of reducing the transmission of viruses within buildings and transport.
The company’s research into anti-microbial glass was already at an advanced stage prior to the COVID-19 pandemic, but the outbreak has made it a key priority for the business’ UK research and development team based in Lathom, Lancashire.
Its work has been supported by a grant from Innovate UK, as part of its nearly $51.5 million of funding to help drive forward technological advances which address new challenges from COVID-19.
The team is studying how coatings can effectively reduce viral loads on a glass surface. According to the World Health Organization, coronaviruses can live on surfaces anywhere from two hours to nine days. The survival time depends on a number of factors, including the type of surface, temperature, relative humidity and specific strain of the virus.
A glass with antiviral properties is expected to help control viruses in areas like shopping centers, hospitals, care homes, schools and public transport. It will also help to make touch screen devices safer, according to the company. As part of the research, NSG Group is looking at how an antiviral layer can be combined with other functionality glass, such as solar control to further extend its applications.
“Curbing the transmission of viruses will be a priority for those who design and manage buildings and transportation for years to come, not least until a vaccine for COVID-19 is found,” says Dr. Neil McSporran, global portfolio manager at NSG Group. “Reducing infection via surfaces that the virus lives on will be an important part of any strategy organizations have to control the virus. This is where antiviral glass would play an important role in reducing the spread of a virus—limiting viral load on high-touch surfaces, like the inside of a bus window or a shopping center door.”
