The Pella® 350 Series from Pella of Lewes features remarkably constructed vinyl replacement windows and patio doors that are energy efficient and priced to appeal to any budget. All of these windows and patio doors match the same high standards as other Pella® replacement windows and patio doors.
Engineered 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 resist warping and twisting over the years. And, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their lasting looks, our DuraColor™ exterior finish exceeds industry standards for fade resistance2, so you can rely on beautiful, vivid colors for years down the road.
In addition to being good-looking and enduring, Pella 350 Series replacement windows and patio doors tout our highest energy efficiency standards. The detail used to create energy efficiency is InsulShield® Advanced Low-E double-pane glass. Filled with argon gas, InsulShield glass options not only shield against high temperatures, but also repel the sun’s UV rays. You can boost your energy efficiency even further with triple-pane glass, which also helps reduce the amount of outside noise that comes into your room.3
