  • between 46%-61% of your homes’ heating energy can be lost; and
  • between 79%-86% of its heat gained through windows.

Beautiful windows are possibly the most complex and interesting elements in the fabric of our homes. They provide light and fresh air, and offer views that connect our interior living spaces with the great outdoors. However, ordinary windows can also represent a major source of unwanted heat gain in summer and significant heat loss in winter. Today, remarkable new framing and glazing materials have changed the energy performance of windows in a radical way.
