Pella® 350 Series Windows and Doors

The Pella® 350 Series from Pella of Baltimore consists of impressively crafted 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.

Engineered with a reinforced frame that’s 83 percent stronger than ordinary 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 enduring looks, 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 durable, 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 defend against extreme temperatures, but also repel the sun’s UV rays. You can increase your energy efficiency even more with triple-pane glass, which also helps lessen the amount of outdoor noise that enters your house.3
