The Pella® 350 Series from Pella of Kelowna consists of well designed vinyl replacement windows and patio doors that are energy efficient and priced to suit any budget. All of these windows and patio doors mirror the same rigorous 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 include precision corner welding to help resist warping and twisting over the seasons. And, our exclusive SmoothSeamTM interior welded corners are virtually invisible. Adding to their continuing beauty, our DuraColor™ exterior finish tops industry standards for fade resistance2, so you can expect beautiful, vivid colors for years to come.
In addition to being appealing and durable, Pella 350 Series replacement windows and patio doors tout our highest energy efficiency standards. The detail 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 deflect the sun’s UV rays. You can improve your energy efficiency even higher with triple-pane glass, which also helps decrease the amount of outside noise that enters your house.3
