The Pella® 350 Series from Pella of Danville features well designed vinyl replacement windows and patio doors that are energy efficient and priced to suit 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 normal vinyl1, Pella 350 Series windows and sliding patio doors also include precision corner welding to help withstand warping and twisting over time. And, 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 rely on beautiful, vibrant colors for years to come.
In addition to being appealing and enduring, 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 defend against extreme temperatures, but also deflect the sun’s UV rays. You can improve your energy efficiency even higher with triple-pane glass, which also helps lessen the amount of outside noise that comes into your home.3
