The Pella® 350 Series from Pella of Salt Lake City 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 reflect the same rigorous 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 prevent warping and twisting over time. Also, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their enduring style, our DuraColor™ exterior finish tops industry standards for fade resistance2, so you can expect beautiful, enduring colors for the foreseeable future.
In addition to being appealing and dependable, Pella 350 Series replacement windows and patio doors tout our highest energy efficiency standards. The feature 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 block the sun’s UV rays. You can boost your energy efficiency even further with triple-pane glass, which also helps reduce the amount of exterior noise that comes into your room.3
