The Pella® 350 Series from Pella of Vancouver features impressively crafted 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 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 include precision corner welding to help resist warping and twisting over the seasons. And, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their lasting style, our DuraColor™ exterior finish exceeds industry standards for fade resistance2, so you can expect 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 protect against high temperatures, but also block the sun’s UV rays. You can improve your energy efficiency even more with triple-pane glass, which also helps reduce the amount of outside noise that comes inside your house.3
