Zen Nirvana double hung window in Soft-lite White with contoured grids
Fusion welded sashes and frame are built to be exceptionally strong and durable, which helps prevent air and water infiltration. Exterior beveled mainframe with drip cap provides contemporary beauty and style. Integral lift rail features comfortable, ergonomic design and is significantly stronger and more durable than snap-in lift rails. Intercept® warm-edge spacer and sealant system is fully automated for condensation resistance and seal integrity. Certa-Force balance system provides smooth and easy operation of double hungs—and never requires lubrication or adjustment. Heavy-duty vent lock allows window to remain partially open for ventilation. Special reinforcement in the meeting rail ensures maximum structural performance and enhances the security of the window. Comfort Foam in the frame is an excellent insulator that improves the window’s thermal effectiveness.
