The Pella® 350 Series from Pella of Bloomington, IN includes remarkably designed 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 high standards as other Pella® replacement windows and patio doors.
Engineered with a reinforced frame that’s 83 percent stronger than normal vinyl1, Pella 350 Series windows and sliding patio doors also feature precision corner welding to help withstand warping and twisting over the seasons. Also, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their lasting beauty, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can count on beautiful, vivid colors for the foreseeable future.
In addition to being appealing and durable, 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 shield against high temperatures, but also block the sun’s UV rays. You can increase your energy efficiency even further with triple-pane glass, which also helps reduce the amount of outdoor noise that comes inside your home.3
