The Pella® 350 Series from Pella of Springfield consists of well constructed vinyl replacement windows and patio doors that are energy efficient and priced to appeal to any budget. All of these windows and patio doors reflect the same demanding standards as other Pella® replacement windows and patio doors.
Engineered with a reinforced frame that’s 83 percent tougher than regular vinyl1, Pella 350 Series windows and sliding patio doors also include precision corner welding to help resist warping and twisting over the years. And, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their continuing style, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can rely on beautiful, vibrant colors for years to come.
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 protect against high temperatures, but also block the sun’s UV rays. You can increase your energy efficiency even more with triple-pane glass, which also helps decrease the amount of outside noise that comes into your home.3
