The Pella® 350 Series from Pella of Greenfield features well 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 match the same demanding 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 include precision corner welding to help withstand warping and twisting over the seasons. Also, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their lasting beauty, our DuraColor™ exterior finish exceeds industry standards for fade resistance2, so you can expect beautiful, vibrant colors for the foreseeable future.
In addition to being beautiful and durable, 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 extreme temperatures, but also block the sun’s UV rays. You can improve your energy efficiency even higher with triple-pane glass, which also helps reduce the amount of outside noise that comes inside your room.3
