Cardinal Insulation Is the Gold Standard of Blown-In Insulation
Jupiter's coastal proximity, intense solar exposure, and year-round humidity create a thermal environment that destroys cheap insulation fast. Builder-grade batts compress, settle, and lose R-value within a few Florida summers. Cardinal's high-density blown-in fiberglass holds its R-value for the life of your roof structure.
Local insight: Jupiter's oceanfront and Intracoastal properties experience elevated salt-air humidity that accelerates the breakdown of organic insulation materials like cellulose — making inorganic fiberglass the superior long-term choice.
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.
