Why Choose Pella Defender Series?

Simplified storm protection.

Designed to weather the storm with exceptional durability, Pella Defender Series impact resistant windows protect your home and everything inside. To prep for the storm, just close and lock your windows. It's that simple.

Reliable, Everyday Performance.

Pella Defender Series windows not only stand up to the storm, they provide noise reduction, excellent energy efficiency and protection against intruders. Keep your home quiet, more comfortable and protected year-round. Laminated, insulated glass blocks 99.7% of UV rays, helping protect your carpet and window treatments from fading.

Easy Installation.

When it comes to performance, installation matters. That's why Pella Defender Series products are equipped with an easy-installation frame design. With holes pre-drilled into the frame, your home is secured quicker and easier.

Improved energy efficiency.

You don't have to sacrifice how comfortable you are in your home for storm protection. Every Pella Defender Series window and patio door comes with insulating Argon gas in between the panes of glass to act like a blanket and reduce heat transfer. A multi chambered frame with up to 18 insulating air chambers helps reduce the transfer of heat, keeping your home more comfortable.

Tested to endure with accelerated environmental testing.

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.
