Atrium Series 8100 windows are engineered with state-of-the-art glass technology to give you outstanding thermal efï¬ciency. It all starts with premium insulated glass: two sturdy panes separated by an optimal air space to create a wide thermal barrier. Between the glass panes is a special insulated spacer designed to flex with the glass in hot or cold temperatures to resist sealant failure. The insulated spacer also helps keep the edges of the glass warmer, dramatically reducing condensation while keeping cold air out and warm air in.
