Our ENERGY STAR®-certified windows and doors will help strengthen the energy efficiency of your home, and you’ll see the benefits no matter the season.

Our Glass 

Our InsulShield® glass collection1 features the most innovative and energy-saving choices, with selections based on specific climates. The options below give our best energy efficiency and protection from weather year-round.

Advanced Low-E Insulating Triple-Pane Glass with Argon2 offers 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 offers insulating double-pane glass with dual coats of Low-E thermal protection. This selection also includes argon inserted between the panes of glass to improve energy efficiency.

Pella’s SunDefense™ Low-E Insulating Double-Pane Glass with Argon2 also uses insulating double-pane glass with a Low-E coating made using three layers of Low-E solar protection to keep your home cooler during the hottest months. This option blocks 95 percent of the sun’s ultraviolet rays and has argon inserted between the glass to improve your energy efficiency.

Determining Energy Efficiency

You can determine 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 includes it between our glass panes to offer extra insulation.
  • Low-Emissivity (Low-E) glass coating reflects heat away from your home when it’s hot and inside the room when it’s cold; plus it blocks harmful UV rays.

Pella Innovation for Gaithersburg Area Home

We’ve engineered features to help our products improve your energy efficiency, including:

  • Various combinations of glass
  • Thermal breaks
  • Unique snap-in between-the-glass blinds and shades
  • Low-E coating removed from the glass edge to prevent the possibility of seal failure
