Insulation Services in Jacksonville, FL
Jacksonville insulation contractors in this directory cover Riverside, Avondale, Mandarin, San Marco, the Beaches, and Mayport. IECC Climate Zone 2A asks for R-38 attics and R-13 walls. Most pre-2000 Jacksonville homes have R-19 to R-30 of compressed batts — topping up with blown insulation runs $1.30-$2.10 per sq ft. Closed-cell foam in walls or under-roof runs $4.50-$7/sq ft at 2 inches and creates a conditioned attic that dramatically improves AC performance.
JEA offers home-performance rebates for qualifying air-sealing and insulation jobs. The 25C federal tax credit covers 30% of qualifying insulation up to $1,200/year. Florida humidity makes vapor management critical — most installers spec a smart vapor retarder rather than a poly barrier in attic and wall assemblies.
