Low-E (low-emissivity) glass features a microscopically thin, virtually clear coating that reduces infrared heat transfer. This coating helps keep unwanted heat out in warmer climates and retains warmth indoors during colder periods, significantly improving a window's thermal efficiency. It's often used within double glazed units to enhance overall energy performance for Australian homes and projects.
