Cardinal Insulation Is the Gold Standard of Blown-In Insulation
Boca Raton homes face intense solar exposure, coastal humidity, and year-round cooling demands. Builder-grade insulation fails fast in this environment. Cardinal's high-density blown-in fiberglass system is engineered specifically for South Florida's climate — and it starts with a thorough attic air seal before a single bag is opened.
Local insight: Boca Raton's coastal proximity means attic humidity levels run significantly higher than inland areas, accelerating the degradation of low-density insulation materials.
Air Sealing First
Every job starts with a thorough attic air seal — closing every bypass before a single bag of insulation is opened. Without this step, even R-38 insulation underperforms.
High-Density Blown Fiberglass
Pure virgin fiberglass — inorganic, moisture-resistant, and dimensionally stable. It holds its R-value for decades in Florida's humid climate.
R-38 Certified Installation
We blow to certified depth, document with photos, and provide R-value certification. Full documentation for permits, insurance, and home sales.
