What is blown-in fiberglass?
Loose strands of spun glass blown through a hose to settle evenly across the attic floor. It’s non-combustible, doesn’t support mold, and stays put for decades when installed correctly.

Blown-In Fiberglass Insulation Guide
Everything you should know before adding blown-in fiberglass to a Florida attic — what it is, what depth you actually need, and how to spot a job done right.

What R-value do you need in Central Florida?
Florida sits in climate zone 2. Code minimum is R-30. We strongly recommend R-38 — about 14 inches of depth — because the savings on cooling are dramatic in our climate (up to 40% off the electric bill).
How to tell if your install was done right
Look for evenly placed depth rulers, consistent fluff (not packed down hard), and no bare wood showing on the joists. Edges should reach the eaves without blocking soffit ventilation.
Lifespan and maintenance
A clean blown-in attic lasts 20–30 years. The two things that shorten its life are roof leaks and rodent traffic — both worth checking yearly.
