Why Blown-In?
The Smart Choice for South Florida Attics
In South Florida's brutal heat, your attic is the #1 source of energy loss. Blown-in insulation — also called loose-fill insulation — is one of the most effective and cost-efficient ways to stop that heat transfer in its tracks.
Cardinal Insulation uses premium fiberglass and cellulose blown-in materials that conform perfectly to your attic's shape, filling every gap, corner, and irregular space that batt insulation simply can't reach.
The result? A fully sealed, uniformly insulated attic that keeps conditioned air inside your home where it belongs — and keeps your AC from running overtime.
The Advantages
6 Reasons to Choose Blown-In Insulation
Lower Energy Bills
Proper attic insulation can reduce cooling costs by 15–25% in South Florida homes. Most homeowners see a return on investment within 2–3 years.
Faster Installation
A typical blown-in attic job is completed in just a few hours with minimal disruption to your home or daily routine.
Complete Coverage
Loose-fill material flows into every corner, joist cavity, and irregular space — delivering uniform coverage that batt insulation can't match.
Eco-Friendly Options
Cellulose blown-in insulation is made from up to 85% recycled content, making it one of the most environmentally responsible insulation choices available.
Noise Reduction
In addition to thermal performance, blown-in insulation adds a meaningful layer of acoustic dampening, reducing outside noise throughout your home.
Florida Code Compliant
All installations meet or exceed Florida Building Code requirements for thermal performance (R-38 to R-60 for South Florida attics).
