Biltmore Forest Homes and Their Attics
Tudor Revival Houses of the Early 1920s
Junius Adams, a founder of the Biltmore Estate Company and the town's first mayor, built one of its earliest houses in 1921. Two fellow directors built similar homes next door in 1922. His house's nomination describes two stories under a steep slate roof, with a stair up to an attic that is partly finished, one corner first used as a servant's room. In an attic like that, heated rooms and cold attic sit side by side. Where a finished room has short walls under the roof slope, the hollow spaces behind and beneath those walls are sealed and insulated too. ENERGY STAR lists them among the common leaks into an attic.
Attic Insulation in Biltmore Forest
About 65 percent of Biltmore Forest's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.
Built from 1940 to 1969, about 40 percent of Biltmore Forest homes often have little insulation.
The Local Climate
Biltmore Forest's center sits about 2,270 feet above sea level, 5 miles from NOAA's Asheville station, the best match for Biltmore Forest. The station's 1991 to 2020 normals average about 3,880 heating and 1,090 cooling degree days a year, so at Biltmore Forest's station, heating needs outweigh cooling.
Readings change over short distances around Biltmore Forest: NOAA's Bent Creek station, 4 miles away, averages about 4,590 heating degree days.

Biltmore Forest Insulation FAQs
Will the Biltmore Forest historic district rules hold up insulating our attic?
No historic commission reviews attic work here. The town says its district was judged eligible for the National Register in 1990, a step short of being listed. Even where a house is listed on its own, the state preservation office says the listing sets no limits on an owner paying for work privately. The town's Design Review Board checks added structures against the town's design standards. Insulation is inside work, but talk to the town first if the attic needs new roof vents.
Our older Biltmore Forest house has a sleeping porch that was closed in. Is it insulated?
Do not assume so. A sleeping porch was meant to be open to the air. At one founder's house, listed on the National Register in 2006, the nomination says the upstairs sleeping porch stayed an open-air room until casement windows closed it in for winter in 1954. A room that began as a porch may have had insulation added later, or never. We look at its ceiling and the roof space above it on their own, apart from the main attic.
Could the old insulation in a Biltmore Forest attic be vermiculite?
It could: about 55 percent of Biltmore Forest's homes predate 1960. If a Biltmore Forest 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 Biltmore Forest need a permit?
Biltmore Forest Town Hall can say whether Buncombe County Permits & Inspections, the town itself or another office handles permits in Biltmore Forest; ask before work starts.
