Pella 150 Series 35-1/2-in x 35-1/2-in White Exterior Vinyl New Construction Single Hung Window Dual-pane Double Pane Glass (Half Screen Included)

150 Series 35-1/2-in x 35-1/2-in White Exterior Vinyl New Construction Single Hung Window Dual-pane Double Pane Glass (Half Screen Included). Pella 150 Series vinyl single-hung windows deliver a classic look with a bottom sash that opens for increased ventilation. Dual-pane NaturalSun Low-E insulating glass provides insulation from the cold, while letting the sun's heat warm your home. The bottom sash slides up and down to provide ventilation with a stationary top sash. Pella’s vinyl uses a fade-resistant formula that is performance-tested for excellent weathering, durability and color retention. All-metal cam-action locks are anchored to the sash, ensuring long-lasting, dependable operation, with a hardware design that complements the window. A cam action lock reengages the sashes and pulls them against the weatherstripping to ensure a superior weathertight seal. Pella 150 Series double-hung windows with high altitude glass are designed for installation between 3,500 feet and 6,500 feet; for installation between 6,500 feet and 8,500 feet, please reference special order. A quick installation frame design helps reduce installation time. Backed by Pella’s limited lifetime warranty, one of the strongest warranties in the industry
