The Pella® 350 Series from Pella of Peoria features remarkably crafted vinyl replacement windows and patio doors that are energy efficient and priced to fit any budget. All of these windows and patio doors mirror the same rigorous standards as other Pella® replacement windows and patio doors.
Developed with a reinforced frame that’s 83 percent sturdier than regular vinyl1, Pella 350 Series windows and sliding patio doors also include precision corner welding to help withstand warping and twisting over the seasons. Plus, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their continuing beauty, our DuraColor™ exterior finish tops industry standards for fade resistance2, so you can expect beautiful, vivid colors for years down the road.
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 defend against intense temperatures, but also block the sun’s UV rays. You can boost your energy efficiency even more with triple-pane glass, which also helps reduce the amount of outside noise that enters your house.3
