The Pella® 350 Series from Pella of Scottsdale consists of remarkably 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 high standards as other Pella® replacement windows and patio doors.
Developed 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 practically invisible. Adding to their lasting beauty, our DuraColor™ exterior finish exceeds industry standards for fade resistance2, so you can count on beautiful, vivid colors for the foreseeable future.
In addition to being beautiful and enduring, Pella 350 Series replacement windows and patio doors are the most energy efficient that we carry. The feature 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 improve your energy efficiency even further with triple-pane glass, which also helps reduce the amount of outdoor noise that comes into your house.3
