The Pella® 350 Series from Pella of Minneapolis features remarkably constructed vinyl replacement windows and patio doors that are energy efficient and priced to fit any budget. All of these windows and patio doors reflect the same high standards as other Pella® replacement windows and patio doors.
Developed 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 withstand warping and twisting over the years. Also, our exclusive SmoothSeamTM interior welded corners are practically invisible. Adding to their enduring looks, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can rely on beautiful, vibrant colors for the foreseeable future.
In addition to being appealing 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 repel the sun’s UV rays. You can increase your energy efficiency even higher with triple-pane glass, which also helps reduce the amount of outdoor noise that comes into your house.3
