What Low-E Coatings Actually Do
Low-E means low emissivity, which sounds technical but is pretty straightforward. The coating reduces heat transfer through the window while still allowing natural light into the room.
That matters on a long Houston summer afternoon, when direct sun can make a room feel several degrees warmer than the thermostat says. Low-E coatings help reduce that solar gain, so windows do less to add heat to the house.
The comfort improvement is often noticeable before the savings show up. A room with coated glass usually feels more balanced, with fewer hot zones near the windows and less of that blast-and-recover cycle from the AC.
