The Local Climate
Ellenboro's center sits about 1,050 feet above sea level, 11 miles from NOAA's Shelby 2 NW station, the best match for Ellenboro. The station's 1991 to 2020 normals average about 3,560 heating and 1,460 cooling degree days a year, so at Ellenboro's station, heating needs outweigh cooling.
Ellenboro sits about 250 feet above the station, so expect slightly colder winters.

Ellenboro Insulation FAQs
Does any historic listing affect my Ellenboro house?
Not that the state's files show. Ellenboro has no entry, in town or nearby, on the Rutherford County pages of the state's National Register listings. The preservation office's 2023 roster of local commissions gives the county only two, belonging to Forest City and Rutherfordton. So no designation stands between you and attic work. An older house here still needs a careful look before insulation goes in.
What comes first in an Ellenboro house from the town's railroad years?
The wiring and the roof. A town founded in 1886 can have houses wired well before 1930. ENERGY STAR names knob-and-tube wiring from those decades as a fire hazard under a blanket of insulation, so an electrician checks it first. Next is the underside of the roof. Insulation that feels damp or shows water stains points to a leak, and the roof gets repaired before any new insulation is blown in.
Could the old insulation in an Ellenboro attic be vermiculite?
It could: about 25 percent of Ellenboro's homes predate 1960. If an Ellenboro attic holds a pebble-like gray-brown or silver-gold fill, leave it undisturbed: the EPA says vermiculite may contain asbestos.
Does attic insulation in Ellenboro need a permit?
Ellenboro Town Hall can say whether Rutherford County Building Inspections, the town itself or another office handles permits in Ellenboro; ask before work starts.
