The Pella® 350 Series from Pella of Tucson features remarkably designed 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 tougher than regular vinyl1, Pella 350 Series windows and sliding patio doors also offer precision corner welding to help prevent warping and twisting over the years. And, our exclusive SmoothSeamTM interior welded corners are nearly invisible. Adding to their continuing beauty, our DuraColor™ exterior finish exceeds industry standards for fade resistance2, so you can expect beautiful, vibrant colors for years to come.
In addition to being good-looking and durable, Pella 350 Series replacement windows and patio doors are our most energy efficient. The detail used to create energy efficiency is InsulShield® Advanced Low-E double-pane glass. Filled with argon gas, InsulShield glass options not only shield against high temperatures, but also block the sun’s UV rays. You can boost your energy efficiency even more with triple-pane glass, which also helps decrease the amount of outdoor noise that comes into your house.3
