Question 1

What is blown-in insulation and where is it used?

Accepted Answer

Blown-in insulation is loose-fill material — usually cellulose or fiberglass — installed with a hose and blowing machine rather than cut into pieces. It's most commonly used on attic floors, where it settles into an even blanket over the ceiling joists, and in existing wall cavities through small access holes. Because it flows, it fills irregular spaces and works around obstructions that batts can't cover cleanly.

Question 2

How much blown-in insulation do I need in a Naples attic?

Accepted Answer

That depends on your target R-value and the material. Cellulose delivers roughly R-3.2 to R-3.8 per inch and loose-fill fiberglass roughly R-2.2 to R-2.7 per inch, so reaching a typical Southwest Florida attic target takes meaningfully more depth with fiberglass. We measure your existing depth, calculate the additional inches needed, and mark installed depth on rulers in the attic so you can verify coverage yourself.

Question 3

Can blown-in insulation be added on top of my existing insulation?

Accepted Answer

Usually yes. If your current insulation is dry, uncontaminated, and evenly distributed, we can blow new material directly over it to top up the R-value — this is one of the most cost-effective insulation upgrades available. If the existing material is wet, moldy, rodent-contaminated, or badly compacted, it needs to come out first. We offer complete insulation removal for exactly that situation.

Question 4

Does blown-in insulation settle or lose performance over time?

Accepted Answer

Some settling is normal and expected, which is why quality installers account for it by installing to a specified settled depth rather than an initial depth. Blown-in cellulose settles more than fiberglass. The bigger long-term risk in Florida is moisture and air movement — loose-fill slows heat transfer but doesn't stop humid air infiltration, so attics with significant air leakage benefit from air sealing before the new insulation goes in.

Question 5

Blown-in insulation or spray foam — which is better for my attic?

Accepted Answer

Blown-in costs less upfront and is excellent for topping up an attic floor quickly. Spray foam costs more but air-seals as it insulates, which matters a great deal in Naples humidity, and it lets you condition the attic by insulating the roof deck instead of the floor. If your HVAC equipment and ductwork live in the attic, spray foam on the roof deck is usually the better long-term investment. If your HVAC is in conditioned space and you just need more R-value overhead, blown-in is hard to beat on value.
