Pella® 350 Series Windows and Doors

The Pella® 350 Series from Pella of West Springfield consists of remarkably constructed vinyl replacement windows and patio doors that are energy efficient and priced to appeal to any budget. All of these windows and patio doors mirror the same high 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 prevent warping and twisting over the seasons. Plus, our exclusive SmoothSeamTM interior welded corners are nearly invisible. Adding to their continuing style, 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 good-looking and enduring, Pella 350 Series replacement windows and patio doors are the most energy efficient that we carry. The feature 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 increase your energy efficiency even more with triple-pane glass, which also helps lessen the amount of exterior noise that enters your home.3
