30 Florida-licensed insulation subcontractors statewide. Create a free* GC account to see phone and email and invite a sub to bid on your RFQ.
Insulation subcontractors install the thermal and acoustic systems on a project — fiberglass batt, blown cellulose and fiberglass, rigid board, spray polyurethane foam, vapor barriers, fire-stopping at penetrations, and acoustic caulks and seals. On commercial jobs they price from the Division 07 spec and the wall and roof assembly details, sequence their work behind framing and MEP rough-in, and carry the assemblies that hit the building's energy code and sound-rating requirements.

When a GC sends an insulation RFQ, they want a quote against the Division 07 spec, the wall and roof assembly details, and the rated assembly schedule. Bids are typically broken out by square foot per assembly type, with separate lines for spray foam by board foot, rigid board by square foot, and fire-stopping by each penetration or lump sum. GCs want the bid to name the R-value per assembly, the product and density (especially for spray foam), and what's excluded — acoustic sealants outside insulation scope, vapor barriers carried by other trades, fire-stopping in MEP-only chases.
Insulation contracting in Florida falls under the specialty contractor classification regulated by the Construction Industry Licensing Board (CILB) under the DBPR. A specialty contractor's license covers the scope of work listed under that classification — installation of thermal and acoustic insulation systems and the related vapor and fire barriers — and can be held at the certified level (statewide) or the registered level (local jurisdiction only). Insulation scope can also be performed by a general contractor (CGC/CBC/CRC) under their broader license. Florida treats unlicensed contracting as a crime, which is why every insulation sub in this directory carries its DBPR license number.
It depends on the assembly. Closed-cell foam is denser, has a higher R-value per inch, and acts as a vapor retarder; open-cell is lighter and used where vapor permeability is desired. RFQs should name the product and density per assembly, since they're priced differently by board foot and the R-value math depends on the type. A clean bid states the product line priced and the inches of thickness assumed.
Fire-stopping at MEP penetrations through rated assemblies is sometimes the insulation sub's scope and sometimes a separate fire-stop sub or the individual MEP trades. The boundary varies by GC and project. RFQs should call out who carries fire-stopping by assembly and by penetration type. A clean insulation bid states the assumption — typically pricing fire-stop in the wall assemblies it's installing.
Sometimes yes, sometimes no. Polyethylene vapor retarders behind batt insulation are often carried by the insulation sub. Self-adhered air barriers and weather-resistive barriers on the exterior are usually a separate scope under the air barrier or waterproofing sub. RFQs should state which trade carries each barrier; bids should list barrier scope by location so the GC can confirm envelope continuity.
Acoustic batt insulation in sound-rated interior partitions is typically unfaced mineral wool or fiberglass sized to fill the stud cavity; thermal batt in exterior walls is faced or unfaced to a stated R-value. They're priced similarly by square foot but the product spec is different, and the install timing differs — acoustic batt goes in before the second side of drywall. RFQs should call out each application by assembly.
The badge reflects what was reviewed: a verified state license earns License Verified — the usual path for an insulation sub — a verified certificate of insurance earns Insurance Verified, and a sub with both reviewed shows the Verified Pro umbrella.
