The Pella® 350 Series from Pella of Indianapolis includes impressively constructed vinyl replacement windows and patio doors that are energy efficient and priced to appeal to any budget. All of these windows and patio doors match the same high standards as other Pella® replacement windows and patio doors.
Created with a reinforced frame that’s 83 percent stronger than ordinary vinyl1, Pella 350 Series windows and sliding patio doors also feature precision corner welding to help resist warping and twisting over the years. Also, our exclusive SmoothSeamTM interior welded corners are nearly invisible. Adding to their lasting style, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can count on beautiful, enduring colors for years down the road.
In addition to being beautiful and durable, Pella 350 Series replacement windows and patio doors are our most energy efficient. The technology used to create energy efficiency is InsulShield® Advanced Low-E double-pane glass. Filled with argon gas, InsulShield glass options not only defend against extreme temperatures, but also deflect the sun’s UV rays. You can boost your energy efficiency even further with triple-pane glass, which also helps decrease the amount of exterior noise that enters your room.3
