The Pella® 350 Series from Pella of El Paso includes 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 mirror the same rigorous standards as other Pella® replacement windows and patio doors.
Engineered 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. Plus, our exclusive SmoothSeamTM interior welded corners are practically invisible. Adding to their lasting looks, our DuraColor™ exterior finish tops industry standards for fade resistance2, so you can rely on beautiful, vivid colors for the foreseeable future.
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 defend against high temperatures, but also deflect the sun’s UV rays. You can increase your energy efficiency even further with triple-pane glass, which also helps decrease the amount of outdoor noise that comes inside your room.3
