Glass is an important aspect for managing the energy efficiency of your home. Our standard glazing is dual pane: two panes of glass with Low E coatings and argon insulating gas. We offer variations to help meet climate and code requirements across the country, described in more detail on our glass page.
The look of multiple, individual panes of glass in a window panel is popular in a wide range of architectural styles. Grilles between the glass, available in a number of different styles, mimic the look of these individual panes of glass without sacrificing energy efficiency.
Grilles are permanently installed between the glass panes for low-maintenance and easy cleaning. Choose from 6 exterior colors and 3 interior colors.
