My residence is situated in southern North Carolina which generally has 5-6 months where the A/C is working virtually all the day/evening and four-5 months exactly where the heat (Gas) is operating.

Folks standing beneath a radiant barrier quickly observe the lesser heat radiated, and I do believe the FSEC reporting which persistently states that radiant barrier cuts down AC use eight-twelve% in households normal for that state.
The upper the number, the more thermal-resistant it's. Essential R-values change by region and weather, and in most cases you’ll want some depth to fulfill the code demands.
