What is a Warm Edge spacer?
Warm edge refers to the type of spacer material used to separate the panes of glass in an insulated window unit. If the material conducts less heat or cold than a conventional aluminum spacer at the edge of the glass, it is said to be ‘warm edge.’ The warm edge spacer affects heat retention and loss, condensation on the windows, and the amount of noise that is transmitted. Best of all, the warm edge spacer reduces your energy costs.
