Cardinal Insulation Is the Gold Standard of Blown-In Insulation
Delray Beach homeowners deal with the same brutal South Florida heat as anywhere in Palm Beach County — but older homes along Atlantic Avenue and the barrier island often have decades-old insulation that's lost most of its R-value. We assess, air seal, and upgrade to a system that actually holds up in Florida's climate.
Local insight: Many Delray Beach homes built in the 1970s–1990s were insulated to standards far below today's Florida Energy Code R-38 requirement, leaving significant energy savings on the table.
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.
