The Pella® 350 Series from Pella of Westerly consists of impressively crafted vinyl replacement windows and patio doors that are energy efficient and priced to fit any budget. All of these windows and patio doors mirror the same high standards as other Pella® replacement windows and patio doors.
Created 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 the years. And, our exclusive SmoothSeamTM interior welded corners are practically invisible. Adding to their continuing beauty, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can expect beautiful, enduring colors for years down the road.
In addition to being appealing and enduring, Pella 350 Series replacement windows and patio doors are the most energy efficient that we carry. The feature used to create energy efficiency is InsulShield® Advanced Low-E double-pane glass. Filled with argon gas, InsulShield glass options not only shield against extreme temperatures, but also block the sun’s UV rays. You can increase your energy efficiency even more with triple-pane glass, which also helps lessen the amount of outside noise that comes inside your room.3
