Attic Insulation in South Florida

I just purchased a single family home in South Florida and I am told that replacing/adding more insulation in my attic will save on the electric bill and it will be more energy efficient. I do have high ceilings and it seems like the AC is running constantly trying to keep the house cool, but also I am in the extremely hot south Florida.

I wanted to know what kind of insulation you would recommend, blown in (which kind) or sprayed (which kind)? I have AC ducts and pipes in the attic.

Thank you in advance!

For adding insulation typ you use blown in, the spray on (foam) is for new construction.

Personally I do not like working with fiberglass so I use cellulose!

I agree, blown insulation is the best way to go. You can either diy or have it done. Most big box stores will give you a free days blower rental if you buy a minimum number of bags. It is important to not restrict air flow thru the attic! This is usually accomplished by using baffles to protect the soffit vents from being covered with the insulation.

Pictures inside and out will help us to guide you. The outside will tell us something about your roof and attic ventilation.

Most fla homes have roofs with a 4/12 pitch. Since the duct work and plumbing supply is in the attic I assume the house is on a concrete slab [very common in fla].

Bklyngirl, what kind of thermostat setting are you using? And is the AC unit newer/higher SEER rating or maybe it's older and a bit inefficient?

Are you a recent transplant or have you been living down here already?
