Your R-38 is overkill for Orange County. In San Diego County, about 15 miles
from the ocean, we have 6" of fiberglass insulation, and this is a custom
house. That's about par for houses in this area. Certainly is all the
insulation we need.

Check with other homeowners in your area. You probably waste your money on
anything over 19.

Hi,

I want to insulate my totally uninsulated attic (I live in Orange
County, CA -- suggested R value in my area is R-38), but my question
is that if I should just buy the krafted fiber insulation from the
Home Depot, which highest R- value is R-30 or get it from somewhere
else. I was interested in PINK fiber Insulation they have batts that
are R-38 and are like 12" compared to the 12" for the Home depot's
brand for only R-30. I am thinking that it may be more economical to
get the PINK R-38 for cost reasons, but don't seem to find a place
where they sell them, and I don't know if PINK is a better brand that
the stuff that the home depot sells.

It's PINK only because the manufacturer, Owens-Corning, wanted to
differentiate their stuff. The pink color is actually part of their
trademark. In other words, it's not the color that makes the difference.
