  • Easy to clean, with no obstruction on the interior or exterior of the glass unit

  • Aluminum bars are sealed within the "airspace" of insulating glass units*

  • The bars allow air-flow throughout the insulating glass unit, creating an unobstructed thermal break, maintaining an energy efficiency not possible with true divided lites

  2. Flat, aluminum bars (finishes below)

  3. "Pencil-shaped" brass bars

  4. "Pencil-shaped" pewter bars
