Pella® 350 Series Windows and Doors

The Pella® 350 Series from Pella of Washington DC consists of impressively constructed vinyl replacement windows and patio doors that are energy efficient and priced to suit any budget. All of these windows and patio doors reflect the same high standards as other Pella® replacement windows and patio doors.

Created with a reinforced frame that’s 83 percent stronger than regular vinyl1, Pella 350 Series windows and sliding patio doors also include precision corner welding to help withstand warping and twisting over the seasons. Plus, our exclusive SmoothSeamTM interior welded corners are nearly invisible. Adding to their lasting style, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can expect beautiful, vibrant colors for years to come.

In addition to being appealing and dependable, Pella 350 Series replacement windows and patio doors are the most energy efficient that we carry. 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 intense temperatures, but also deflect the sun’s UV rays. You can improve your energy efficiency even more with triple-pane glass, which also helps lessen the amount of outdoor noise that enters your room.3
