The Pella® 350 Series from Pella of Annapolis features 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 match the same rigorous 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 offer precision corner welding to help prevent 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 tops industry standards for fade resistance2, so you can rely on beautiful, enduring colors for the foreseeable future.
In addition to being beautiful and durable, Pella 350 Series replacement windows and patio doors tout our highest energy efficiency standards. The detail 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 deflect the sun’s UV rays. You can improve your energy efficiency even further with triple-pane glass, which also helps lessen the amount of exterior noise that comes inside your room.3
