The Pella® 350 Series from Pella of Lafayette includes impressively designed vinyl replacement windows and patio doors that are energy efficient and priced to suit any budget. All of these windows and patio doors mirror the same demanding standards as other Pella® replacement windows and patio doors.
Engineered with a reinforced frame that’s 83 percent sturdier than normal vinyl1, Pella 350 Series windows and sliding patio doors also feature precision corner welding to help prevent warping and twisting over time. Also, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their enduring beauty, our DuraColor™ exterior finish exceeds industry standards for fade resistance2, so you can rely on beautiful, enduring colors for years down the road.
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 intense temperatures, but also deflect the sun’s UV rays. You can increase your energy efficiency even higher with triple-pane glass, which also helps reduce the amount of outdoor noise that comes into your home.3
