The Pella® 350 Series from Pella of Syracuse includes remarkably crafted vinyl replacement windows and patio doors that are energy efficient and priced to suit any budget. All of these windows and patio doors mirror the same high standards as other Pella® replacement windows and patio doors.
Created with a reinforced frame that’s 83 percent sturdier than normal vinyl1, Pella 350 Series windows and sliding patio doors also offer precision corner welding to help resist warping and twisting over the years. Plus, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their lasting beauty, our DuraColor™ exterior finish tops industry standards for fade resistance2, so you can rely on beautiful, vibrant colors for years down the road.
In addition to being beautiful and enduring, Pella 350 Series replacement windows and patio doors are the most energy efficient that we carry. 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 block the sun’s UV rays. You can increase your energy efficiency even further with triple-pane glass, which also helps reduce the amount of outside noise that comes inside your home.3
