The Pella® 350 Series from Pella of Northern Virginia consists of 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 high standards as other Pella® replacement windows and patio doors.
Created with a reinforced frame that’s 83 percent sturdier than regular vinyl1, Pella 350 Series windows and sliding patio doors also feature precision corner welding to help resist warping and twisting over time. Also, our exclusive SmoothSeamTM interior welded corners are practically invisible. Adding to their continuing style, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can expect beautiful, vibrant 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 shield against high temperatures, but also block the sun’s UV rays. You can increase your energy efficiency even further with triple-pane glass, which also helps lessen the amount of outside noise that enters your house.3
