Commercial Insulation for South Florida Properties
commercial insulation is the workhorse of Florida attic retrofits. We will tell you plainly when it is the right specification and when a less expensive approach delivers the same outcome.
South Florida sits in South Florida, where the recommended attic target is R-38 to R-49. That number, along with where your ductwork runs and what condition the existing assembly is in, is what determines the right specification for your property.

Types and Methods
Spray-foam roof decks
Closed-cell spray foam applied to the underside of commercial roof decks. It insulates, acts as a vapor barrier, and adds structural wind resistance — critical for hurricane-zone commercial buildings. Delivers the highest R-value per inch and the largest cooling-load reduction.
Metal-building insulation systems
Fiberglass blanket, rigid foam board, or closed-cell foam engineered for metal building envelopes. We address condensation, radiant heat, and thermal bridging — the three problems that plague uninsulated metal buildings in South Florida.
Sound-rated demising walls
Mineral wool or dense-pack cellulose in demising walls for multi-family and tenant build-outs. We deliver STC ratings that meet or exceed Florida Building Code for sound transmission between units.
Commercial insulation is project-priced based on assembly, square footage, and code requirement. We provide detailed proposals for your GC and project budget, and we coordinate scheduling from bid to closeout.
