Pella® 350 Series Windows and Doors

The Pella® 350 Series from Pella of Hunt Valley features impressively crafted vinyl replacement windows and patio doors that are energy efficient and priced to appeal to any budget. All of these windows and patio doors mirror the same high standards as other Pella® replacement windows and patio doors.

Engineered with a reinforced frame that’s 83 percent sturdier than regular vinyl1, Pella 350 Series windows and sliding patio doors also include precision corner welding to help withstand warping and twisting over time. And, 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, vibrant colors for the foreseeable future.

In addition to being beautiful and enduring, 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 high temperatures, but also repel the sun’s UV rays. You can boost your energy efficiency even more with triple-pane glass, which also helps lessen the amount of outdoor noise that enters your house.3
