Boca Raton's Insulation Specialists
Stop Losing Money Through Your Attic.
Florida's heat doesn't stop at your roof. We engineer high-density blown-in insulation systems that cut cooling costs and keep your home comfortable year-round.
What We Do
Insulation Engineered for Florida
High-Density Blown Fiberglass
Moisture-resistant fiberglass blown to precise depth creates a seamless thermal blanket across your entire attic floor. Long-term R-value stability that holds up against Florida's humidity.
Meticulous Attic Air Sealing
We locate and seal every hidden bypass — plumbing penetrations, electrical gaps, recessed lights — before insulating. Stopping hot humid air infiltration is the first step to real energy savings.
Florida Code Compliant Installation
Every project is engineered to meet or exceed R-38 standards required by Florida Building Code. Proper documentation provided for permits and home sales.
Why Cardinal
Built for Florida. Engineered for Results.
Cardinal Insulation was founded by South Florida contractors who understood that generic insulation solutions fail in our climate. Florida homes face solar heat gain, extreme humidity, and year-round cooling demands that require a different approach — higher density, better air sealing, and materials chosen specifically for our environment. We don't subcontract. Every job is performed by our trained crew, to our standards, with our guarantee.
