Renewal by Andersen® of Northeast PA is excited to announce the introduction of SmartSun™ with HeatLock™ Glass, the most energy-efficient glass we have ever offered. This new glazing system was specifically designed to meet the more stringent ENERGY STAR® requirements for windows in the Northern Zone. With this new glass offering, you get near triple-pane performance in a dual-pane window!
Why HeatLock™ Glass?
Updated ENERGY STAR requirements for windows and doors took effect on January 1, 2015, with updated requirements for the Northern region going into effect on January 1, 2016. As ENERGY STAR requirements increase, Renewal by Andersen is working hard to develop products that are more energy-efficient.
In northern climates with high altitude requirements, not all High Performance glazing systems can perform at the more stringent 2016 levels. However, Renewal by Andersen’s SmartSun with HeatLock will meet and exceed compliance in all areas.
How HeatLock™ Works
While other glazing systems are designed to reflect heat off windows in warm climates, High Performance SmartSun Low-E4® HeatLock Glass is also engineered to keep heat inside the home. The advanced Low-E coating is applied to the roomside surface of the glass unit, in addition to the soft coat Low-E coating (a.k.a. SmartSun™) on the exterior surface of the glass unit. This additional roomside energy barrier is highly durable and reflects heat back into the interior, increasing insulating properties during colder times of the year.
In addition, HeatLock allows in virtually as much natural daylight as our standard High Performance™ SmartSun™ glass. SmartSun™ with HeatLock™ glass is available to order on all Renewal by Andersen windows and patio doors, plus all grille options are compatible with this glass.
