Low-E Glass and SHGC Ratings for Hot-Humid Climates Like Brandon, FL

For hot-humid homes, the difference between a decent window and the right window often comes down to low-E coatings and SHGC ratings.

Why Glass Performance Matters In A Florida Cooling Climate

In a hot-humid climate, the goal is usually not to trap heat from the sun, it is to keep unwanted solar heat out while still letting in useful daylight.

The lower the SHGC, the less solar heat enters the house.

In Florida, a lower SHGC is usually helpful because the air conditioning is already fighting high outdoor temperatures and high humidity.

Low-E, short for low emissivity, uses a thin coating that reduces radiant heat transfer through the glass.
