The Pella® 350 Series from Pella of Fargo features well designed vinyl replacement windows and patio doors that are energy efficient and priced to fit any budget. All of these windows and patio doors reflect the same high standards as other Pella® replacement windows and patio doors.
Developed with a reinforced frame that’s 83 percent sturdier than normal vinyl1, Pella 350 Series windows and sliding patio doors also include precision corner welding to help prevent warping and twisting over the seasons. And, our exclusive SmoothSeamTM interior welded corners are practically invisible. Adding to their continuing style, 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 enduring, Pella 350 Series replacement windows and patio doors are our most energy efficient. 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 repel the sun’s UV rays. You can boost your energy efficiency even higher with triple-pane glass, which also helps reduce the amount of outdoor noise that enters your home.3
