Pella® 350 Series Windows and Doors

The Pella® 350 Series from Pella of Plattsburgh includes remarkably designed vinyl replacement windows and patio doors that are energy efficient and priced to appeal to any budget. All of these windows and patio doors reflect the same high standards as other Pella® replacement windows and patio doors.

Developed with a reinforced frame that’s 83 percent stronger than ordinary vinyl1, Pella 350 Series windows and sliding patio doors also feature precision corner welding to help prevent warping and twisting over the years. And, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their enduring beauty, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can count on beautiful, enduring colors for the foreseeable future.

In addition to being good-looking and dependable, Pella 350 Series replacement windows and patio doors are the most energy efficient that we carry. The technology used to create energy efficiency is InsulShield® Advanced Low-E double-pane glass. Filled with argon gas, InsulShield glass options not only protect against intense temperatures, but also repel the sun’s UV rays. You can improve your energy efficiency even further with triple-pane glass, which also helps decrease the amount of exterior noise that comes inside your room.3
