Spray Foam Insulation License Requirements in Tennessee
General building contractor licensure applies above $25,000; the exact insulation classification name needs direct verification.
License Requirement
Licensing body: Tennessee Board for Licensing Contractors
Tennessee's Board for Licensing Contractors lists "Insulation of Mechanical Work" (CMC-E) under its Mechanical Contractor classification, but that specifically covers pipe and duct insulation — not general building-envelope SPF work. General building insulation likely falls under a Building Construction (BC-A through F) classification or a Board-assigned Specialty license (which requires only a Business & Law exam, no trade exam). A license is required for projects at or above $25,000 (materials plus labor).
SPFA Certification Relevance
SPFA (Spray Polyurethane Foam Alliance) certification is not a legal requirement here — no state licensing board makes it a condition of licensure. It remains a voluntary industry credential that some manufacturers require for warranty coverage and that SPFA's Professional Certification Program (PCP) references in federal Unified Facilities Guide Specifications (UFGS) for government contracts.
Bonding & Insurance Facts
A specific bond or insurance dollar figure was not confirmed from a primary source — Tennessee's official classification outline PDF was not accessible during our research. Confirm current bonding requirements and the correct classification directly with the Board.

Research note: The $25,000 threshold and CMC-E mechanical-insulation classification are confirmed, but the correct classification name for general building-envelope SPF work needs direct verification with tn.gov/commerce before publishing as settled fact.
