Researchers at the University of British Columbia have created metal-coated glass that increases light transmission by as much as 10% compared to traditional window glass. Although glass is transparent, metallic inclusions allow more light to flow through the treated glass.
Metallic glass means conductive glass
In addition to increasing light transmission, the metallic inclusions also make the glass conductive. Ordinary glass is not just non-conductive; it’s used as an insulator in a variety of applications. Making glass conductive opens up some new possibilities for energy conservation, including the creation of “programmable” windows that can either reflect or absorb heat, based on the needs of the occupants.
Using windows to control heat gain or loss is especially interesting in Canada, where 70% of the country’s energy usage is devoted to maintaining the temperature in buildings. The experimental glass was created using a vacuum deposition technique, and added a metallic layer just a few nanometers thick.
You can use Glassprimer™ glass paint to help control heat gain and loss in building interiors. Ordinary glass allows UV-radiation to pass through it virtually unimpeded. In the winter, any additional heat is welcome, but often the angle of the winter sun doesn’t lend itself to heat gain via glass. On the other hand, you can also use coatings on the glass to help retain heat during the winter.
Glassprimer™ glass paint allows natural light to penetrate the glass, but provides exceptional UV resistance. Glass coated with Glassprimer™ glass paint will resist solar heat gain, and can also help prevent heat loss at night and during the winter months.
Glassprimer™ glass paint is economical as well. You can apply Glassprimer™ glass paint and achieve complete coverage for a cost of about $1.00 per square foot. Because Glassprimer™ glass paint makes a permanent bond with the glass, it will not chip, fade or delaminate, even in direct sunlight.
No one knows how well “smart” windows will work, or even if they’re practical, but we do know that Glassprimer™ glass paint offers a practical, affordable solution for limiting heat gain and loss.
