The Pella® 350 Series from Pella of Charlotte 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 reflect the same rigorous standards as other Pella® replacement windows and patio doors.
Developed with a reinforced frame that’s 83 percent sturdier than normal vinyl1, Pella 350 Series windows and sliding patio doors also offer precision corner welding to help prevent warping and twisting over time. Plus, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their continuing style, our DuraColor™ exterior finish exceeds industry standards for fade resistance2, so you can rely on beautiful, vivid colors for the foreseeable future.
In addition to being appealing and enduring, Pella 350 Series replacement windows and patio doors are our most energy efficient. 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 deflect the sun’s UV rays. You can improve your energy efficiency even more with triple-pane glass, which also helps reduce the amount of outdoor noise that enters your room.3
