The 30-Second Verdict
Both Owens Corning and CertainTeed produce excellent insulation products widely used in Florida. For attic insulation upgrades (the most common FL project), Owens Corning EcoTouch and CertainTeed InsulSafe are virtually identical in performance — both are fiberglass blown-in products that deliver Florida-appropriate R-values efficiently. Brand matters less than proper installation to the right R-value with proper air sealing.
