The Pella® 350 Series from Pella of Memphis consists of impressively crafted vinyl replacement windows and patio doors that are energy efficient and priced to suit 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 include precision corner welding to help withstand warping and twisting over the seasons. Also, 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, enduring colors for the foreseeable future.
In addition to being good-looking and dependable, 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 high temperatures, but also block the sun’s UV rays. You can improve your energy efficiency even further with triple-pane glass, which also helps decrease the amount of outside noise that comes inside your house.3
