150 Series West 35-1/2-in x 59-1/2-in White Exterior Vinyl New Construction Single Hung Window Low-E argon Double Pane Glass with Grids, (Half Screen Included). Pella 150 Series vinyl single-hung windows deliver a classic look with a bottom sash that opens for increased ventilation. SunDefenseTM Low-E glass lets in light while helping to block heat, keeping homes cooler in the summer and warmer in the winter. 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 performancetested 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. Color-matched grilles are permanently sealed between the panes of insulating glass to create a smooth glass surface while giving the look of traditional panes. A quick installation frame design helps reduce installation time. Backed by Pella’s limited lifetime warranty, one of the strongest warranties in the industry
