The Pella® 350 Series from Pella of Shrewsbury includes remarkably designed 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.
Engineered with a reinforced frame that’s 83 percent stronger than normal vinyl1, Pella 350 Series windows and sliding patio doors also offer precision corner welding to help prevent warping and twisting over time. Plus, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their lasting beauty, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can count on beautiful, vibrant colors for years to come.
In addition to being appealing and durable, Pella 350 Series replacement windows and patio doors tout our highest energy efficiency standards. 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 intense 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 room.3
