The Pella® 350 Series from Pella of Muncie consists of 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 match the same rigorous standards as other Pella® replacement windows and patio doors.
Engineered with a reinforced frame that’s 83 percent tougher than normal vinyl1, Pella 350 Series windows and sliding patio doors also include precision corner welding to help resist warping and twisting over the years. Plus, our exclusive SmoothSeamTM interior welded corners are nearly invisible. Adding to their lasting beauty, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can rely on beautiful, vivid colors for years down the road.
In addition to being beautiful and dependable, Pella 350 Series replacement windows and patio doors tout our highest energy efficiency standards. The feature used to create energy efficiency is InsulShield® Advanced Low-E double-pane glass. Filled with argon gas, InsulShield glass options not only protect against intense temperatures, but also block the sun’s UV rays. You can increase your energy efficiency even more with triple-pane glass, which also helps reduce the amount of outdoor noise that comes into your home.3
