The Pella® 350 Series from Pella of Decatur includes remarkably crafted vinyl replacement windows and patio doors that are energy efficient and priced to appeal to any budget. All of these windows and patio doors mirror the same demanding standards as other Pella® replacement windows and patio doors.
Developed with a reinforced frame that’s 83 percent stronger than ordinary vinyl1, Pella 350 Series windows and sliding patio doors also feature precision corner welding to help prevent warping and twisting over time. And, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their continuing style, our DuraColor™ exterior finish tops industry standards for fade resistance2, so you can rely on beautiful, vibrant colors for years down the road.
In addition to being good-looking and durable, Pella 350 Series replacement windows and patio doors are the most energy efficient that we carry. The technology used to create energy efficiency is InsulShield® Advanced Low-E double-pane glass. Filled with argon gas, InsulShield glass options not only defend against high temperatures, but also block the sun’s UV rays. You can increase your energy efficiency even higher with triple-pane glass, which also helps decrease the amount of outside noise that comes inside your room.3
