The Pella® 350 Series from Pella of Terre Haute consists of impressively crafted 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.
Developed with a reinforced frame that’s 83 percent sturdier than regular vinyl1, Pella 350 Series windows and sliding patio doors also feature precision corner welding to help prevent warping and twisting over the seasons. Plus, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their lasting looks, our DuraColor™ exterior finish exceeds industry standards for fade resistance2, so you can rely on beautiful, enduring colors for the foreseeable future.
In addition to being appealing and durable, Pella 350 Series replacement windows and patio doors are the most energy efficient that we carry. The technology used to create energy efficiency is InsulShield® Advanced Low-E double-pane glass. Filled with argon gas, InsulShield glass options not only defend against intense temperatures, but also repel the sun’s UV rays. You can increase your energy efficiency even more with triple-pane glass, which also helps lessen the amount of exterior noise that comes into your room.3
