The Pella® 350 Series from Pella of Monroe consists of well crafted vinyl replacement windows and patio doors that are energy efficient and priced to suit any budget. All of these windows and patio doors match the same rigorous standards as other Pella® replacement windows and patio doors.
Engineered with a reinforced frame that’s 83 percent sturdier than normal vinyl1, Pella 350 Series windows and sliding patio doors also feature precision corner welding to help withstand warping and twisting over time. Also, 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, enduring colors for years down the road.
In addition to being beautiful 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 protect against extreme temperatures, but also block the sun’s UV rays. You can boost your energy efficiency even more with triple-pane glass, which also helps reduce the amount of outdoor noise that comes into your room.3
