The Pella® 350 Series from Pella of Greensboro consists of remarkably crafted 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 rigorous standards as other Pella® replacement windows and patio doors.
Created with a reinforced frame that’s 83 percent stronger 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. Also, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their continuing looks, our DuraColor™ exterior finish tops industry standards for fade resistance2, so you can rely on beautiful, vivid colors for years down the road.
In addition to being appealing and enduring, Pella 350 Series replacement windows and patio doors tout our highest energy efficiency standards. The detail used to create energy efficiency is InsulShield® Advanced Low-E double-pane glass. Filled with argon gas, InsulShield glass options not only defend against intense temperatures, but also deflect the sun’s UV rays. You can increase your energy efficiency even more with triple-pane glass, which also helps decrease the amount of outside noise that comes inside your house.3
