| Glaverbel invests in Italian production of superinsulating glass ![]() The investment is a new step by Glaverbel towards sustainable development. "Replacing ordinary single glazing with coated superinsulating double glazing cuts CO2 emissions by 91 kg per square metre per year, " points out Jean-François Heris, President and CEO of Glaverbel. To cover the European demand Glaverbel will be able to call on four plants, all equipped with specialised magnetron low-E coating units: Tiel (Netherlands), Teplice (Czech Republic), Klin (Russia) and Cuneo. The coatings are almost invisible layers of metal oxide deposited on the surface of the glass, giving it greater thermal insulation against cold and/or heat. They can be applied in-line on the hot float glass, or they can be deposited under vacuum in a magnetron. Depending on the composition of the coatings, superinsulating glass (also known as "low emissivity" or "low-E" glass) can have its U value (level of heat loss) reduced to 1.1, compared with 2.8 for ordinary double glazing and 5.8 for single glazing. In other words, superinsulating double glazing has more than twice the insulating power of ordinary double glazing. For this reason it is strongly encouraged by governments in numerous countries. write your comments about the article :: © 2007 Construction News :: home page |
