What Energy STAR Window Ratings Mean for Louisiana Homeowners

In Louisiana, windows live in a tough environment, with months of air conditioning, high moisture, and storm risk pressing on every frame.

What the Energy STAR Label Actually Tells You

Think of ENERGY STAR as a pass-fail overlay on lab-tested metrics. You still need to read the numbers to match a window to your home.

The core numbers come from the National Fenestration Rating Council label that rides with the ENERGY STAR mark.

• Focus on a low U-factor to keep conditioned air inside and outdoor heat out.
• Pick a low SHGC to tame west and south exposures where solar gain drives up indoor temperatures.
• Visible Transmittance (VT) is the fraction of visible light that passes through. Higher is brighter, but pairing bright glass with low SHGC requires selective coatings.
• A tighter AL reduces dust, humidity creep, and noise - a plus near high-traffic corridors like Highway 190 in Mandeville.
• CR hints at how prone the interior glass or frame will be to sweating when the AC is running. The higher, the better.
