The Pella 350 Series includes energy-efficient vinyl windows and a patio door, which are up to 83% more energy efficient than wood and fiberglass alternatives. The 350 Series includes a full line of two-, three-, or four-panel configurations for patio doors and single-hung, double-hung, sliding, casement, awning, fixed-frame, and special-shape windows. Three frame colors (white, almond, and white interior–brown exterior) are available, including a dual-color option, and the series offers five hardware finishes: white, almond, bright brass, satin nickel, and oil-rubbed bronze. pellaadm.com
