Last week I wrote about the early strategies window manufacturers employed to improve energy performance: adding extra layers of glass and increasing the thickness of the airspace between the layers ...

Energy-efficient windows often feature multiple glass panes, gas fills, low-e coatings, and well-insulated frames. Proper installation is crucial to ensure a window's energy efficiency benefits are ...

Last week I identified the four energy bands that determined the effectiveness of windows: visible, solar near IR, re-radiated mid IR and thermal convection. Each energy band requires its own ...

HOUSTON – (July 10, 2025) – A new coating for glass developed by Rice University researchers and collaborators could help reduce energy bills, especially during the cold season, by preventing ...

A new coating for glass developed by Rice University researchers and collaborators could help reduce energy bills, especially during the cold season, by preventing heat-loss from leaky windows. The ...

Heat gain or loss through windows accounts for 25% to 30% of our home’s heating and cooling energy use. Drafty windows are another common issue that leads to high utility bills and inconsistent indoor ...
