Pella® 350 Series Windows and Doors

The Pella® 350 Series from Pella of Champaign includes 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 match the same rigorous standards as other Pella® replacement windows and patio doors.

Engineered 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 resist warping and twisting over the seasons. And, our exclusive SmoothSeamTM interior welded corners are nearly invisible. Adding to their lasting style, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can expect beautiful, vibrant colors for years down the road.

In addition to being good-looking and enduring, Pella 350 Series replacement windows and patio doors are our most energy efficient. The detail 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 block the sun’s UV rays. You can boost your energy efficiency even further with triple-pane glass, which also helps lessen the amount of outdoor noise that enters your home.3
