About 15 percent of Green Level's homes predate 1970; if your joists show above the insulation, ENERGY STAR says to add more insulation.

The Local Climate
Green Level's center sits about 610 feet above sea level, 4 miles from NOAA's Haw River 1 E station, the best match for Green Level. The station's 1991 to 2020 normals average about 3,550 heating and 1,590 cooling degree days a year, so at Green Level's station, heating needs outweigh cooling.

Green Level Insulation FAQs
Is any part of Green Level on a historic register?
No, going by the state's records. No Green Level property is on the National Register, and the 2023 state roster shows no historic commission for the town. Alamance County's 2014 inventory does record two surveyed sites, the commercial center along NC 49 and Green Level Christian Church from about 1940. Being surveyed puts no rules on a house. So attic work here needs no historic approval.
My Green Level house dates from the town's early growth. Did the builder have to insulate the attic?
No law made them. The town traces its first wave of new houses to the 1960s, and North Carolina tied insulation standards to new homes only for those begun in 1978 or later. What is up there now depends on the builder and on every owner since. So on install day the crew measures the depth in several spots with you, including out at the eaves, where it is often thinnest.
I bought a house in Bedford Hills. Is there anything to check in a newer attic?
A few things, even in a house this new. The town says the Bedford Hills subdivision was finished in 2019, so its houses were built under the state's insulation standards. Still, look for insulation spread evenly with no low spots, soffit vents that are not buried, and bath or kitchen fans that run outdoors rather than into the attic. ENERGY STAR's attic guides flag all three as things to set right.
Does attic insulation in Green Level need a permit?
Green Level Town Hall can say whether Alamance County Inspections, the town itself or another office handles permits in Green Level; ask before work starts.
