When properly installed, attic insulation helps to keep conditioned air in the home during the winter and out of it during the summer, significantly cutting energy bills. In addition, insulation provides a barrier against insects and moisture, helping to protect the attic, roof, and walls.

When choosing attic insulation, consider the R-value required by your climate zone and the dimensions of your attic space. The higher the R-value, the more efficient your attic will be.

Spray Foam Genie Charleston, which consists of precut fiberglass rolls, is an affordable option and has good R-value per inch. However, it doesn’t do well with moisture and may take a long time to dry if it gets wet. It’s also not as effective at reducing outside noise as wall insulation.

Spray Foam Insulation: The Best Choice for Charleston Attics

Cellulose and foam insulation are more expensive, but they have better R-value per inch than fiberglass. They’re also more effective at sealing gaps and cracks. Foam insulation consists of a liquid that’s sprayed into the wall cavity and expands upon curing, creating a solid, insulating layer. This type of attic insulation doesn’t have any paper or foil backing, but it is dangerous if inhaled and should be handled by professionals.

Once you’ve determined the R-value needed for your attic, choose the type of insulation that works best for your needs and budget. Whether you select foam, cellulose, or fiberglass, make sure to apply an air vapor barrier in your attic before adding insulation. This prevents moisture from rising into the rooms below and causing mold or mildew.
