Blown-in fiberglass is one of the most practical ways to insulate an attic in South Florida. Loose-fill fiberglass is blown into place with a machine, so it settles into the gaps around joists, wiring and framing that rolled batts tend to leave open. Stuff and Puff Insulation Experts installs blown-in fiberglass in homes and businesses across Miami-Dade.
Why Blown-In Fiberglass Works in Miami
- Slows attic heat. Most of the heat that reaches your living space in summer comes down through the attic. A thick, even layer of insulation slows it before it reaches your ceilings.
- Fills irregular spaces. Because it is blown in, it covers awkward corners and crowded attics evenly.
- Handles humidity. Glass fibers do not absorb water or feed mold the way some organic materials can.
- Non-combustible. Fiberglass itself does not burn.
Where We Install It
Attic floors are the most common job, from topping up thin existing insulation to insulating an attic from scratch. Blown-in fiberglass can also be installed in enclosed wall cavities and other hard-to-reach spaces.
Frequently Asked Questions
How much attic insulation does a Miami home need?
ENERGY STAR recommends R-30 to R-49 for an uninsulated attic in South Florida’s climate zone, or adding R-25 to R-30 if you already have 3–4 inches.
Can new insulation go over old insulation?
Often, yes, as long as the old insulation is dry and free of mold, pests or damage. If it is not, it should be removed first.
Is blown-in fiberglass better than batts?
In most attics, blown-in gives more even coverage because it fills gaps around obstructions. Batts can work well in open, regular framing.
