In South Georgia, Energy.gov recommends insulation with an R-Value of 30-60 for attics, 22-38 for cathedral ceilings, 13-15 for cavity (room walls), and 13 for floor insulation.

Say you find 14 inches of blown-in cellulose insulation, which has a typical R-value of around R-3.5 per inch, in your attic. That means your attic is insulated to about R-49, or 14 x 3.5.

Insulation ratings comparison (per inch) There are numerous home insulation materials available. To compare their insulating ability, look at each one’s R-value per inch of thickness.

Unraveling the Mysteries of R-Values One term you will inevitably come across when dealing with insulation is R-value. R-value measures the thermal resistance of insulation materials – in other words, ...

Batt and poly insulation are also good choices that offer R-values of around 3-4 per inch. Lastly, they highlight that the R-value of fiberglass can vary depending on the density of the material.

At R-13.1, the boards are only 2 inches thick (lower-value boards are even thinner), making this an ideal insulation for homes where wall space is restricted.

When applied to exterior walls, comparing dynamic insulation to static high-R insulation (current practice), the potential for total source energy savings is estimated to be 51.2% for homes located in ...

Increasing Home Value with Insulation When it comes to mid-range remodels, homeowners recoup most, if not all, of their fiberglass attic insulation investments in resale value, according to ...

Matthew Coates of Coates Design Architects + Interiors recommends these baords for their high R-value insulation. They are easy to cut and fit, block mildew and scored an impressive 4.7/5 on Lowes.

Selecting Insulation Spray Foam — Closed cell spray foam seals and insulates at the same time, but it needs up to 24 hours to cure, a process that can include off-gassing.
