The Pella® 350 Series from Pella of Raleigh 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 reflect the same high standards as other Pella® replacement windows and patio doors.
Engineered with a reinforced frame that’s 83 percent stronger than ordinary vinyl1, Pella 350 Series windows and sliding patio doors also offer precision corner welding to help resist warping and twisting over the seasons. And, 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 count on beautiful, enduring colors for years to come.
In addition to being good-looking and durable, Pella 350 Series replacement windows and patio doors tout our highest energy efficiency standards. The technology 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 boost your energy efficiency even more with triple-pane glass, which also helps decrease the amount of outdoor noise that comes into your room.3
