Pella® 350 Series Windows and Doors

The Pella® 350 Series from Pella of Boise features remarkably constructed 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.

Developed with a reinforced frame that’s 83 percent sturdier than ordinary vinyl1, Pella 350 Series windows and sliding patio doors also include precision corner welding to help resist warping and twisting over time. Plus, our exclusive SmoothSeamTM interior welded corners are practically invisible. Adding to their enduring style, our DuraColor™ exterior finish tops industry standards for fade resistance2, so you can rely on beautiful, enduring colors for years to come.

In addition to being good-looking and dependable, Pella 350 Series replacement windows and patio doors tout our highest energy efficiency standards. 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 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 decrease the amount of outside noise that enters your room.3
