The Pella® 350 Series from Pella of Providence consists of well designed 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 tougher than ordinary 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 continuing beauty, our DuraColor™ exterior finish exceeds industry standards for fade resistance2, so you can rely on beautiful, enduring colors for the foreseeable future.
In addition to being appealing and dependable, Pella 350 Series replacement windows and patio doors are the most energy efficient that we carry. 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 block the sun’s UV rays. You can boost your energy efficiency even further with triple-pane glass, which also helps decrease the amount of exterior noise that enters your house.3
