“Low-E” Windows Maximize Buildings’ Energy Efficiency

“Low-E” Windows Maximize Buildings’ Energy Efficiency (photo: EWC)

Low-E stands for low emissivity, and these windows are constructed to minimize heat transfer through the glass. Since windows are essentially huge holes in the walls of a building, choosing a low-E window design that’s appropriate for local climate and architecture can greatly increase a structure’s thermal efficiency, while reducing energy use and utility costs.
