Pella® 350 Series Windows and Doors

The Pella® 350 Series from Pella of South Burlington features well 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 demanding standards as other Pella® replacement windows and patio doors.

Developed with a reinforced frame that’s 83 percent stronger than ordinary vinyl1, Pella 350 Series windows and sliding patio doors also include precision corner welding to help withstand warping and twisting over the years. Also, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their continuing style, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can count on beautiful, enduring colors for years down the road.

In addition to being good-looking and durable, Pella 350 Series replacement windows and patio doors are our most energy efficient. The detail 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 block the sun’s UV rays. You can increase your energy efficiency even further with triple-pane glass, which also helps reduce the amount of outside noise that comes inside your house.3
