Attic Insulation

I live in Central Florida in a 12 year old house with R19 insulation.
Does the insulation lose some of its efficiency in this number of
years? If so, what type of insulation do you recommend for
florida. The insulation I have is called (blown in).

The fiberglass dosen't lose its efficiency. It is only about 10% efficient against summer heat. Adding more will not be of much help, if any.

Contact FI-FOIL insulation co. in Auburndale, Fl ( 800 448-3401). They manufacture radiant barrier insulation, which would be the most effiecent for your situation and can probably tell you who to contact for installation. This is also a DIY type product. You could probably lay a TYPE 2 perforated material over the existing insuation. The radiant barrier will reflect abpoiut 97% of the heat back out preventing it from going thru thru fiberglass.

The Florida Solar Energy Center is a big advocte of radiant barriers.

Thank you for considering my opinion.
