Pella® 350 Series Windows and Doors

The Pella® 350 Series from Pella of Denver features well designed 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 high standards as other Pella® replacement windows and patio doors.

Created with a reinforced frame that’s 83 percent stronger than regular vinyl1, Pella 350 Series windows and sliding patio doors also offer precision corner welding to help prevent warping and twisting over the seasons. Plus, our exclusive SmoothSeamTM interior welded corners are nearly invisible. Adding to their continuing looks, our DuraColor™ exterior finish tops industry standards for fade resistance2, so you can count on beautiful, vibrant colors for the foreseeable future.

In addition to being beautiful and durable, 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 shield against intense temperatures, but also repel the sun’s UV rays. You can boost your energy efficiency even further with triple-pane glass, which also helps decrease the amount of outdoor noise that enters your home.3
