Guardian’s new vacuum insulating product delivers 10 times the R-value of single-pane glass
Guardian Vacuum IG™ will debut at the American Institute of Architects Convention in New York City 21-23 June, where it will be on show to give visitors an idea of how this new insulating product uses a vacuum between two panes of glass that prevents heat from escaping to the outside, and thus insulating like a wall. The product provides transformative thermal insulation with an R-value of up to 12 for 8-mm thickness, compared to single pane glass at R-1. Because Guardian Vacuum IG uses tempered glass, the product is suitable for use in commercial buildings.
VIG performance is enhanced by pairing Guardian Vacuum IG with Guardian SunGuard® coated glass to create a hybrid, low-E VIG glass product that delivers the light transmission, reflectivity and colour they need for new construction or retrofits. All this with noise reduction that exceeds that of a typical insulating glass unit.
“At R-14, Guardian Vacuum IG hybrids with low-E glass coatings have an R-value three times the value of a standard insulating glass unit or a double IGU with low-E,” explains Chad Simkins, director of sales and marketing, Guardian Glass Fabrication. “Our tempered glass VIG can go into any application to bring value to projects by helping them meet stringent building codes.”
According to the National Fenestration Rating Council, about one third of a building’s heating and cooling passes through (fenestration), Guardian Vacuum IG helps break through those old expectations for glass performan...
