Viracon is pleased to introduce ExtremEdge™, a new warm edge spacer designed to improve edge of glass u-value by as much as 13% over an aluminum spacer.
When energy codes focus on edge of glass u-value the intent is to decrease thermal heat loss of the window while improving the energy efficiency of a building.To meet these requirements, ExtremEdge is constructed with a lower thermal conductivity biopolymer material which is encapsulated in stainless steel.
In addition to improved u-values, the increased surface temperature of the bottom edge will improve the relative humidity (RH) value, thus minimizing the opportunity for condensation.
