The Pella® 350 Series from Pella of Kingston 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 reflect the same rigorous standards as other Pella® replacement windows and patio doors.
Developed with a reinforced frame that’s 83 percent tougher than ordinary vinyl1, Pella 350 Series windows and sliding patio doors also offer precision corner welding to help prevent warping and twisting over the years. And, our exclusive SmoothSeamTM interior welded corners are nearly invisible. Adding to their continuing looks, our DuraColor™ exterior finish exceeds industry standards for fade resistance2, so you can count on beautiful, enduring 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 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 high temperatures, but also deflect the sun’s UV rays. You can increase your energy efficiency even further with triple-pane glass, which also helps reduce the amount of outside noise that enters your house.3
