Kentucky's climate attacks residential windows through the combination of mechanisms that the state's position at the intersection of the Ohio River valley humidity corridor, the central Appalachian moisture belt, and the Ohio Valley severe storm corridor produces simultaneously — the 50-to-60 freeze-thaw cycles per heating season that Louisville and central Kentucky average deposit condensation moisture at window balance hardware, lock cam contacts, casement operator gears, and frame seal connections through each Kentucky winter; the ice storms that make Kentucky one of the most ice-storm-prone states in the US load window sashes, screens, and frame seals with freezing rain adhesion that prevents operable windows from opening through the thaw period and drives moisture infiltration through any compromised glazing or frame seal; the Ohio River valley humidity that Louisville, Covington, Paducah, and the communities along Kentucky's river corridors sustain through spring, summer, and early fall drives wood sill deterioration, wood sash summer swelling, and IGU edge seal moisture infiltration faster than Kentucky's inland communities produce at the same hardware specification; and Kentucky's April-through-June severe storm season delivers hail impact and wind-driven debris to residential glass across the state's storm-active western and central communities.
