The neighborhoods surrounding Mizner Park and Palmetto Park Road in downtown Boca Raton (zip code 33432) include some of the city's most established residential streets. Many of these homes were built in the 1960s, 1970s, and 1980s — and most have attic insulation that has never been upgraded since original construction. Cardinal Insulation works throughout this area and understands the specific challenges of older Boca Raton homes.

The 33432 Insulation Profile

Zip code 33432 covers the area east of I-95 and south of Yamato Road — including neighborhoods along Palmetto Park Road, Federal Highway, and the streets surrounding Mizner Park. This is some of Boca Raton's oldest residential construction.

1960s homes: Many homes in this area were built with minimal insulation — R-7 or less, sometimes just a thin layer of fiberglass or even no insulation at all in the attic floor. These homes have the most to gain from an upgrade.

1970s homes: R-11 was the standard in the 1970s. After 50+ years, this insulation has compressed significantly — most 1970s homes in 33432 are performing at R-7 to R-9.

1980s homes: R-19 builder-grade batts, now compressed to R-11 to R-14. Still well below Florida's current R-38 minimum.

Older Homes, Unique Challenges

Homes near Mizner Park and downtown Boca Raton often present challenges that newer construction doesn't:

Knob-and-tube wiring: Some older homes in this area have older electrical systems that require special handling during insulation work. Our assessors identify these situations during the free inspection.

Irregular attic access: Older construction often has smaller, less accessible attic hatches. We carry equipment to handle tight access points without damaging ceilings or trim.

Mixed construction: Many homes in this area have been renovated or added onto over the decades, creating attic spaces with multiple sections at different heights and configurations.

Coastal humidity: Proximity to the Intracoastal and Atlantic means higher ambient humidity — which accelerates insulation degradation and makes moisture-resistant fiberglass blown-in the preferred material.

The Payoff: Dramatic Comfort Improvement

For homes in 33432 that have been running on R-7 to R-11 insulation for decades, the improvement from a blown-in upgrade to R-49 or R-60 is dramatic:

• Immediate comfort improvement — rooms that have always been hot in summer become noticeably cooler within days of installation
• 25–40% reduction in FPL cooling costs — measurable on the first bill after installation
• Reduced HVAC cycling — your air conditioning runs less frequently, reducing wear and extending equipment life
• Improved indoor air quality — properly sealed and insulated attics reduce the infiltration of outdoor air, dust, and allergens
