The Pella® 350 Series from Pella of Roanoke features impressively crafted vinyl replacement windows and patio doors that are energy efficient and priced to fit any budget. All of these windows and patio doors match the same high standards as other Pella® replacement windows and patio doors.
Developed with a reinforced frame that’s 83 percent tougher than regular vinyl1, Pella 350 Series windows and sliding patio doors also offer precision corner welding to help withstand warping and twisting over the years. Plus, our exclusive SmoothSeamTM interior welded corners are nearly invisible. Adding to their enduring looks, our DuraColor™ exterior finish tops industry standards for fade resistance2, so you can expect beautiful, vivid 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 protect against high temperatures, but also block the sun’s UV rays. You can boost your energy efficiency even more with triple-pane glass, which also helps lessen the amount of exterior noise that comes into your house.3
