What Energy STAR Window Ratings Mean for Louisiana Homeowners

Between the heat, moisture, and wind that define our climate, Louisiana homes need windows that do more than look good. That is where ENERGY STAR window labels earn their keep, giving you a simple way to compare performance that translates directly into comfort, utility savings, and durability.

Understanding the Energy STAR Label

The label is a performance stamp, not a brand, meaning a window has been third-party tested and meets minimum requirements tailored to climate.

Every ENERGY STAR window carries NFRC ratings. These are the numbers that drive real-world performance.

• U-factor is the insulation value. The smaller the number, the better the window resists heat moving through it.
• SHGC tells you how much solar energy a window admits. In Louisiana, look for a low number to cut AC load.
• You can get plenty of light without the heat if the glass uses a selective low-e coating that keeps SHGC low while VT stays moderate.
• Air Leakage (AL) estimates how much air slips around the sash and frame under pressure. Lower means tighter, less drafty windows.
• CR hints at how prone the interior glass or frame will be to sweating when the AC is running. The higher, the better.

Given our climate, target low U-factor and SHGC together, then make AL as tight as your budget allows. That trio delivers real savings and comfort.
