The Pella® 350 Series from Pella of Sheridan includes remarkably crafted vinyl replacement windows and patio doors that are energy efficient and priced to fit any budget. All of these windows and patio doors match the same high standards as other Pella® replacement windows and patio doors.
Created with a reinforced frame that’s 83 percent sturdier than ordinary vinyl1, Pella 350 Series windows and sliding patio doors also feature precision corner welding to help withstand warping and twisting over the years. 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, enduring colors for the foreseeable future.
In addition to being beautiful and enduring, 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 deflect the sun’s UV rays. You can increase your energy efficiency even more with triple-pane glass, which also helps lessen the amount of outdoor noise that comes into your house.3
