Kentucky's climate attacks exterior doors through the full combination of mechanisms that the state's Ohio River valley humidity corridor, Northern climate zone freeze-thaw cycling, ice storm frequency, and severe storm season deliver simultaneously — the 50-to-60 freeze-thaw cycles per heating season that Louisville and central Kentucky average deliver condensation moisture to lock cylinder pin tumbler contacts, hinge pivot barrels, latch bolt cam contacts, and frame perimeter seal adhesive connections through each Kentucky winter; the Ohio River valley humidity that Louisville, Covington, and Paducah sustain through spring, summer, and early fall swells wood door slabs and frames to summer binding dimensions while simultaneously deteriorating wood sill fiber through the sustained moisture absorption that structural sill rot produces over multiple Kentucky seasonal cycles; the frost heave that Kentucky's freeze-thaw shoulder seasons produce at foundation sill and threshold connections racks door frames out of the plumb-and-square geometry that door panel operation depends on; the ice storm events that make Kentucky one of the most ice-storm-prone states in the US freeze weatherstrip contacts and apply ice loading to storm door closers and panel-to-frame contact positions; and Kentucky's April-through-June severe storm season that delivers wind loading to storm doors, storm door closer mounting hardware, and entry door weatherstripping.
