The Pella® 350 Series from Pella of Tysons Corner includes impressively crafted vinyl replacement windows and patio doors that are energy efficient and priced to fit any budget. All of these windows and patio doors mirror the same rigorous standards as other Pella® replacement windows and patio doors.
Created with a reinforced frame that’s 83 percent sturdier than ordinary vinyl1, Pella 350 Series windows and sliding patio doors also offer precision corner welding to help resist warping and twisting over time. Plus, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their continuing looks, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can rely on beautiful, enduring colors for years to come.
In addition to being good-looking and dependable, Pella 350 Series replacement windows and patio doors are the most energy efficient that we carry. The feature used to create energy efficiency is InsulShield® Advanced Low-E double-pane glass. Filled with argon gas, InsulShield glass options not only protect against extreme temperatures, but also deflect the sun’s UV rays. You can boost your energy efficiency even more with triple-pane glass, which also helps lessen the amount of outdoor noise that comes into your room.3
