At Pella, we have a history of sustainability, and we’re dedicated to protecting the environment, including locally in Washington DC. Whether that’s through our own business practices or making energy-saving products, we make every effort to be green. Our ENERGY STAR®-certified windows and doors will help enhance the energy efficiency of your home, and you’ll feel the benefits all year long.
Our InsulShield® glass collection1 provides the most innovative and energy-saving choices, with selections based on specific climates. The options below give our best energy efficiency and protection from the elements year-round.
Advanced Low-E Insulating Triple-Pane Glass with Argon2 features three panes of glass and up to three layers of Low-E thermal protection, with argon between the glass panes.
Our Advanced Low-E Insulating Double-Pane Glass with Argon2 uses insulating double-pane glass with dual coats of Low-E thermal protection. This glass also includes argon inserted between the panes of glass to add energy efficiency.
Pella’s SunDefense™ Low-E Insulating Double-Pane Glass with Argon2 also offers insulating double-pane glass with a Low-E coating formed from three layers of Low-E solar protection to keep your home cooler when it’s hot outside. This option blocks 95 percent of the sun’s ultraviolet rays and has argon inserted into the space between the glass to add energy efficiency.
Consult your Washington DC Pella Showroom to learn about more insulating glass options or our recommended glass for the Washington DC region.
What’s Your Energy Efficiency?
You can figure out your energy efficiency by looking for three primary features:
- Multiple panes of glass – two or three layers of glass equals more layers of protection between the outdoors and your home.
- Argon is a colorless, non-toxic gas that’s denser than air. Pella inserts it between two or more glass panes to give increased insulation.
- Low-Emissivity (Low-E) glass coating reflects heat away from your home during the summer months and inside the room when it’s cold; and it blocks harmful UV rays.
Our Innovation for Washington DC Area Home
We’ve provided features to help our products improve your energy efficiency, including:
- Various combinations of glass
- Thermal breaks
- One-of-a-kind snap-in between-the-glass blinds and shades
