Pella® 350 Series Windows and Doors

The Pella® 350 Series from Pella of Norwalk features remarkably constructed vinyl replacement windows and patio doors that are energy efficient and priced to suit any budget. All of these windows and patio doors mirror the same demanding standards as other Pella® replacement windows and patio doors.

Created with a reinforced frame that’s 83 percent stronger 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 virtually invisible. Adding to their enduring style, our DuraColor™ exterior finish exceeds industry standards for fade resistance2, so you can expect beautiful, vivid colors for the foreseeable future.

In addition to being good-looking and durable, 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 extreme temperatures, but also deflect the sun’s UV rays. You can improve your energy efficiency even higher with triple-pane glass, which also helps reduce the amount of exterior noise that comes into your room.3
