Our ENERGY STAR®-certified windows and doors will help you increase the energy efficiency of your home, and you’ll feel the benefits in every season.

Glass Options  

Our InsulShield® glass collection1 features the most innovative and energy-saving choices, with options based on your climate. The styles below offer our best energy efficiency and protection from the sun and temperatures 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.

Our Advanced Low-E Insulating Double-Pane Glass with Argon2 features insulating double-pane glass with two coats of Low-E thermal protection. This glass 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 features insulating double-pane glass with a Low-E coating formed from 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 add energy efficiency.

Consult your Raleigh Pella Showroom to learn about more insulating glass styles or our recommended glass for the Raleigh region.

Determining Energy Efficiency

You can determine energy efficiency by looking for three primary features:

  • Multiple panes of glass – two or three layers of glass provides 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 our glass panes to provide 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; plus it blocks harmful UV rays.

Pella Innovation for Raleigh Area Home

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

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