Pella® 350 Series Windows and Doors

The Pella® 350 Series from Pella of San Antonio consists of well 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.

Developed with a reinforced frame that’s 83 percent tougher than regular 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 nearly invisible. Adding to their continuing style, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can expect beautiful, vibrant colors for years down the road.

In addition to being good-looking and dependable, 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 shield against intense temperatures, but also block the sun’s UV rays. You can improve your energy efficiency even higher with triple-pane glass, which also helps lessen the amount of outside noise that enters your house.3
