The Pella® 350 Series from Pella of Davenport consists of 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 match the same demanding standards as other Pella® replacement windows and patio doors.
Created with a reinforced frame that’s 83 percent tougher than ordinary vinyl1, Pella 350 Series windows and sliding patio doors also feature precision corner welding to help prevent warping and twisting over the years. Plus, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their enduring looks, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can count on beautiful, enduring colors for the foreseeable future.
In addition to being beautiful and dependable, Pella 350 Series replacement windows and patio doors tout our highest energy efficiency standards. The feature used to create energy efficiency is InsulShield® Advanced Low-E double-pane glass. Filled with argon gas, InsulShield glass options not only shield against extreme temperatures, but also block the sun’s UV rays. You can improve your energy efficiency even further with triple-pane glass, which also helps decrease the amount of outdoor noise that comes into your house.3
