Inside Pella Defender Series
Pella Defender Series windows are created to endure harsh weather conditions. Our exclusive vinyl formula uses high-grade resins and additives for excellent weathering, durability and color retention. And we test samples of our materials and components of our products by placing them in conditions to mimic the intensity of Florida’s sun, coastal salt spray and above average humidity.
