Frequently Asked Questions

What type of insulation is best for a Florida attic?
A radiant barrier combined with blown-in insulation is a popular Florida combination that reduces heat gain and improves R-value simultaneously.
Can I add insulation on top of existing insulation in Florida?
Yes — for most Florida attics with inadequate existing insulation, blown-in insulation can be added directly on top without removing old insulation (as long as the old insulation is dry, undamaged, and not moldy). Simply add blown-in fiber until the combined depth achieves your target R-value.
How much can attic insulation reduce my Florida electric bill?
Compare Owens Corning and CertainTeed on blown-in product, batt products, spray foam, using the actual models or local proposals. Ask for supporting documentation and a written explanation of how the proposed option meets your needs.
