The Pella® 350 Series from Pella of Mt. Pleasant features impressively 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 mirror the same high standards as other Pella® replacement windows and patio doors.
Engineered with a reinforced frame that’s 83 percent tougher than ordinary vinyl1, Pella 350 Series windows and sliding patio doors also feature precision corner welding to help withstand warping and twisting over time. Plus, our exclusive SmoothSeamTM interior welded corners are nearly invisible. Adding to their enduring style, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can count on beautiful, vivid colors for years down the road.
In addition to being beautiful and durable, Pella 350 Series replacement windows and patio doors are our most energy efficient. The feature 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 repel the sun’s UV rays. You can boost your energy efficiency even more with triple-pane glass, which also helps decrease the amount of outdoor noise that comes into your house.3
