Pella® 350 Series Windows and Doors

The Pella® 350 Series from Pella of Ketchum consists of well designed vinyl replacement windows and patio doors that are energy efficient and priced to appeal to any budget. All of these windows and patio doors reflect the same demanding standards as other Pella® replacement windows and patio doors.

Created with a reinforced frame that’s 83 percent sturdier than normal vinyl1, Pella 350 Series windows and sliding patio doors also include precision corner welding to help prevent warping and twisting over time. Plus, our exclusive SmoothSeamTM interior welded corners are practically invisible. Adding to their enduring looks, our DuraColor™ exterior finish tops 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 our most energy efficient. 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 intense 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 outdoor noise that enters your room.3
