Carolina Shores Homes and Their Attics
Eight Planned Communities, Several Kinds of Home
The town describes itself as eight planned communities. The first, the Carolina Shores subdivision, was the whole town at the start and is laid out partly around a golf course. It holds single-family houses, patio homes and villas, plus one-acre lots in a section called The Acreage. Calabash Lakes mixes single-family homes with paired ranches and townhomes, and Beacon Townes, a townhouse community, began in November 2005. If your top-floor ceiling has recessed lights, ENERGY STAR wants a 3 inch gap between insulation and any can without an insulation-contact rating. We read every fixture's label before blowing anything in.
Attic Insulation in Carolina Shores
If the joists show above the insulation in a Carolina Shores attic, ENERGY STAR says to add more insulation.
From 1990 to 2009, about 45 percent of Carolina Shores homes were built to codes below ENERGY STAR's target; check their eaves, where ENERGY STAR says insulation is often thinnest.
The Local Climate
Carolina Shores' center sits about 50 feet above sea level, 8 miles from NOAA's Longwood station, the best match for Carolina Shores. The station's 1991 to 2020 normals average about 2,670 heating and 1,830 cooling degree days a year, so Carolina Shores attics work in both seasons.
Readings change over short distances around Carolina Shores: NOAA's North Myrtle Beach Airport, SC station, 10 miles away, averages about 2,340 heating degree days. The state energy code marks Brunswick County warm and humid.
Homes by Age: What It Means for the Attic
Some 83 percent of Carolina Shores housing units are detached single-family houses.

Carolina Shores Insulation FAQs
My Carolina Shores kitchen has boxed soffits over the cabinets. Do they affect the attic?
They can. ENERGY STAR lists dropped soffits that are open to the attic among the main places a house leaks air, and notes they can be buried under insulation and hard to spot. From the attic side, we pull the insulation back, plug any open stud spaces and cover the top of the soffit, sealing its edges. Then the insulation goes back over it. ENERGY STAR advises sealing an attic before adding insulation, because a loose layer on top does not stop air rising through an open soffit.
Can the attic over one half of a paired ranch in Carolina Shores be insulated?
Yes. Paired ranches and townhomes are part of the town's mix, in Calabash Lakes and Beacon Townes, and the attic over your own ceiling can be done on its own. On install day the crew looks first at the wall that divides your attic from your neighbor's. Where it has gaps or stops short of the roof, air and loose insulation can pass between the two sides, so we point that out before blowing anything in. New roof vents or other outside changes are worth clearing with your owners' association first.
Does attic insulation in Carolina Shores need a permit?
Carolina Shores Town Hall can say whether Brunswick County Permits & Development, the town itself or another office handles permits in Carolina Shores; ask before work starts.
