Pella® 350 Series Windows and Doors

The Pella® 350 Series from Pella of Haverhill consists of 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 mirror the same high standards as other Pella® replacement windows and patio doors.

Developed with a reinforced frame that’s 83 percent stronger than regular vinyl1, Pella 350 Series windows and sliding patio doors also offer precision corner welding to help resist warping and twisting over the years. Also, our exclusive SmoothSeamTM interior welded corners are nearly invisible. Adding to their lasting beauty, our DuraColor™ exterior finish surpasses industry standards for fade resistance2, so you can expect beautiful, vivid colors for years down the road.

In addition to being appealing 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 defend 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 outside noise that comes into your room.3
