Thank you to the amazing Window Source installation crews! This project consists of replacing 100+ inefficient windows with our 6000 Series Picture Windows with Double LowE. Low-E, meaning “low emissivity,” is an extremely thin layer of metallic particles, or more commonly, several layers, applied to the glass that, in simple terms, allows the glass to act as a sieve. This energy-efficient upgrade will keep everyone warm this winter inside the Newton County Library. Interested in energy-efficient replacement windows? Stop by the Newton County Library in Covington, cozy up with a good book, and feel the different energy-efficient windows can make in your home.
