Best Windows for Louisiana
Recommended: Double-pane Low-E with very low SHGC (≤0.22)
Louisiana's extreme heat and humidity mean solar heat gain control is paramount. SHGC ≤ 0.22 dramatically reduces AC loads. In hurricane-risk areas, impact-resistant glass is strongly recommended. Salt air in coastal areas requires vinyl or fiberglass frames.
