Pella® 350 Series Windows and Doors

The Pella® 350 Series from Pella of Wilmington features well constructed vinyl replacement windows and patio doors that are energy efficient and priced to fit 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 normal vinyl1, Pella 350 Series windows and sliding patio doors also feature precision corner welding to help resist warping and twisting over time. And, 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, vibrant 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 technology used to create energy efficiency is InsulShield® Advanced Low-E double-pane glass. Filled with argon gas, InsulShield glass options not only protect against extreme 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 exterior noise that enters your room.3
