What are Warm Edged Spacer Bars?

Often we see condensation and even frost on windows, typically around the edges of window glass. The edge is where the panes of the sealed units are held apart by highly conductive aluminum spacer bars. Condensation is the No. 1 reason for window-related callbacks. Non-conductive warm edges spacer bars reduce transmission of hear and reduces the chance of condensation forming. The material the spacer is made from affects the rate that heat travels through a window’s edge. Warm edge spacers can improve the U-value of a window by 10% and boost the edge temperature by around 5°F, thereby reducing condensation.
