The Low-Emissivity (Low-E) Glass Difference Low-e glass helps your home be more energy efficient and comfortable thanks to an almost invisible, microscopically thin coating that blocks out solar energy and keeps in furnace heat. As you can see from the thermography image below, you can feel the dramatic difference this thin coating can make. The window with low-e glass transmits far less heat than the clear glass window. All that heat is being blocked by the low-e coating. Choose low-e glass windows to feel more comfortable year-round, and for years to come.
