Insulation Subcontractors in Fort Myers (Lee, Hendry & Glades Counties), FL

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 license earns License Verified, a verified certificate of insurance earns Insurance Verified, and a sub with both reviewed shows both badges. Because insulation has no state license, the certificate of insurance is the credential most insulation subs upload, so Insurance Verified is the natural badge for the trade.
