The Pella® 350 Series from Pella of Newport includes impressively 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.
Engineered with a reinforced frame that’s 83 percent sturdier than ordinary vinyl1, Pella 350 Series windows and sliding patio doors also feature precision corner welding to help withstand warping and twisting over the seasons. Plus, our exclusive SmoothSeamTM interior welded corners are practically invisible. Adding to their lasting looks, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can expect beautiful, enduring colors for the foreseeable future.
In addition to being good-looking and durable, Pella 350 Series replacement windows and patio doors are our most energy efficient. The technology used to create energy efficiency is InsulShield® Advanced Low-E double-pane glass. Filled with argon gas, InsulShield glass options not only shield against intense temperatures, but also block the sun’s UV rays. You can boost your energy efficiency even higher with triple-pane glass, which also helps decrease the amount of outside noise that enters your room.3
