The Pella® 350 Series from Pella of Rochester consists of 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 mirror the same demanding standards as other Pella® replacement windows and patio doors.
Developed with a reinforced frame that’s 83 percent sturdier than ordinary 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 looks, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can expect beautiful, vivid colors for years to come.
In addition to being appealing 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 shield against high temperatures, but also block the sun’s UV rays. You can increase your energy efficiency even more with triple-pane glass, which also helps reduce the amount of outside noise that comes inside your house.3
