ExtremEdge™ Decreases Windows’ Thermal Heat Loss and
Increases Energy Efficiency
OWATONNA, MN…Viracon, the nation’s leading single-source architectural glass fabricator, has added a warm edge spacer to its product offering. ExtremEdge™ is designed to improve edge of glass u-value.
ExtremEdge decreases thermal heat loss of windows, satisfying ever-more stringent energy codes and standards of sustainable design. To meet these requirements, the spacer is constructed with a biopolymer material and encapsulated in stainless steel. These materials reduce the edge’s conductivity and heat transfer into the building.
In addition to improving u-values, ExtremEdge also results in a higher interior surface temperature than aluminum or stainless steel spacers when measured at the bottom edge of the glazing unit. The increased temperature improves relative humidity values, minimizing interior condensation.
“We developed ExtremEdge to address increasing energy requirements and stricter energy codes,” says Kevin Anez, Director of Marketing and Product Management at Viracon. “We’re proud to meet, and often exceed, the industry’s growing demand for sustainable design options.”
Spacers are placed between two or more lites of glass to provide an insulating glass unit. Viracon offers glass spacers in a variety of materials, finishes, and thicknesses.
