Why Cape Coral attics cost so much to cool
A Cape Coral attic hits 130 to 150 degrees on a summer afternoon, sitting directly above your ceiling and around your AC ducts — and the DOE estimates those ducts lose 20 to 30 percent of their air. Most pre-2010 homes here were built at just R-11 to R-19 against a R-49 to R-60 target, and that insulation has settled since.
We seal before we insulate
Every Cape Coral attic project we do air-seals the ceiling plane, seals and insulates the ducts, installs baffles to protect soffit ventilation, and builds R-value to code target. Going from R-11 to a sealed R-38+ typically trims 15 to 25 percent off a Lee County cooling bill.
