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.
Choosing Your Window
Create a signature look with solid- or dual-color frames. Made with our performance-tested, exclusive vinyl formula, you won’t have to paint, stain or refinish your windows.
Styling Your Window
Automatically locking hardware comes standard on your single-hung windows. When you close the window, they automatically lock to help keep your home more secure.
Choose between different grille applications to add design interest to your home.
InView™ window screens let in 14% more light and are 8% more open for improved airflow compared to conventional screens.5
