Pella® 450 Series Windows and Doors

Pella® 450 Series aluminum-clad wood windows and patio doors present the natural appeal of wood and unique Pella features at a modest price. Available in a variety of styles, these top notch windows and patio doors are built to improve performance and energy efficiency.

Pella of Gaithersburg offers the Pella 450 Series with common details like window and patio door trim that we can prefinish for you. They can be personalized with multiple grilles and low-maintenance, aluminum-clad exteriors in a variety of colors to match your home’s style.

The exterior of Pella 450 Series windows include a tough, EnduraClad® finish that prevents fading and chalking. Inside your home, your skillfully-designed wood windows will be covered by Pella EnduraGuard® wood protection. This special treatment provides added security against the effects of moisture and decay, marks from mold and mildew, and termite damage.

The InsulShield® energy-efficient glass collection brings some of our most state-of-the-art options, and many Pella glass choices are ENERGY STAR® certified in the United States and Canada. That means you could improve the environment and could even save money on your heating and cooling costs.
