Key Energy Considerations for Gulf South Patio Doors

You want a low U-factor, a moderate to low SHGC that windows Mandeville LA suits your sun exposure, a tight air leakage rating, and a design pressure that meets local wind zones.

U-factor tells you how fast heat moves through the door, so a lower number holds the AC you are paying for.

Dial SHGC to orientation: low for afternoons on the water side, moderate for shaded or north exposures.

Air leakage ratings matter year round here because wind driven rain will find gaps.

DP ratings tell you how the door handles wind loads, which rise near open water and during hurricane season.
