New EnergyVue vinyl windows, with insulated glass and multichambered frames, meet or exceed Energy Star standards in all climate zones. An aluminum interlock design provides added strength for larger window sizes, says the company. The line includes proprietary features such as SecureConnect Technology, which integrates corner keys into the sash of each window, and ComfortLift Handles and TrueHold Hinges for smooth operation. Twenty-five standard shapes are available, as are a variety of frame colors, hardware finishes, and glass tints.

For expansive views, the SL80/81 Folding Series offers the thinnest and most energy-efficient glass wall on the market, according to the company. The use of thermally broken aluminum frames and a triple-insulated core ensures premium performance. Panels can be up to 10 feet tall and 3 feet wide. The SL80 features a rounded frame profile, while the SL81 is more angular. Various configuration options, including inward or outward opening, are available for both models.
