The Pella® 350 Series from Pella of Birmingham includes remarkably constructed vinyl replacement windows and patio doors that are energy efficient and priced to suit any budget. All of these windows and patio doors reflect the same rigorous 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 include precision corner welding to help withstand warping and twisting over the years. Plus, our exclusive SmoothSeamTM interior welded corners are nearly invisible. Adding to their enduring style, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can rely on beautiful, enduring colors for years to come.
In addition to being appealing and enduring, 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 defend against extreme temperatures, but also repel the sun’s UV rays. You can boost your energy efficiency even more with triple-pane glass, which also helps lessen the amount of exterior noise that comes inside your home.3
