Kings Mountain Homes and Their Attics

Hip Roofs and Center Chimneys at Margrace

The Margrace Mill Village, at the city's southwest edge, holds 46 one-story frame mill houses built for workers at the Neisler family's Margrace and Patricia mills. Its most common type is a four-room house under a broad, low hip roof, with a brick chimney rising near the center. Another type began as duplexes paired under one hip roof around central chimneys. Under that kind of roof, the attic pinches down toward each outside wall, and the chimney stands near its tallest point. The gap around that chimney is closed with aluminum flashing and high-temperature caulk, and a sheet-metal dam keeps insulation off the brick.

Turn-of-the-Century Cottages in the West End

The West End Historic District, just west of the railroad, spans houses from about 1882 to about 1955, and most of them date from 1900 to 1939. Its nomination notes a small group of turn-of-the-century one-story cottages with rear ells, most of them later remodeled or rebuilt as bungalows. A house wired in those early decades may still have knob-and-tube circuits hidden in the attic. ENERGY STAR warns that this wiring can be a fire hazard when insulation touches it. An electrician looks at it before we start, and any live run is left uncovered until it is replaced.

Attic Insulation in Kings Mountain

About 40 percent of Kings Mountain's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.

Built from 1970 to 1989, about 30 percent of Kings Mountain homes may hold settled fiberglass; check its depth against the joists.

The Local Climate

Kings Mountain's center sits about 1,000 feet above sea level, 15 miles from NOAA's Lincolnton 4 W station, the best match for Kings Mountain. The station's 1991 to 2020 normals average about 3,330 heating and 1,470 cooling degree days a year, so at Kings Mountain's station, heating needs outweigh cooling.

Kings Mountain Insulation FAQs

Does a Margrace mill house still fall under any mill or historic rules?

Not the mill's rules, and not the National Register's. The Neisler company sold the village houses, mostly to the families living in them, in the autumn of 1956. The village joined the National Register in 2009. Per the State Historic Preservation Office, that listing sets no rules for an owner doing private work with private money. Insulating your attic is your own decision. The only limits are the ones the house sets: low edges, a center chimney and, in some houses, a rear ell.

We closed in the front porch of our Kings Mountain mill house. Is it under the attic?

Not always the same attic. The Margrace nomination records owners on Cloninger Street enclosing their shed-roofed front porches to gain a room, since some of those houses had only one bedroom. If the porch kept its own shed roof, the ceiling of that room sits under a separate, shallow space, or under none at all. We look at it apart from the main attic. Wherever insulation goes, ENERGY STAR wants it spread evenly, without low spots.

Could the old insulation in a Kings Mountain attic be vermiculite?

It could: about 30 percent of Kings Mountain's homes predate 1960. If a Kings Mountain 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 Kings Mountain need a permit?

Kings Mountain City Hall can say whether Cleveland County Building Inspections, the city itself or another office handles permits in Kings Mountain; ask before work starts.
