Insulation contractors contract with clients to line and cover structures with insulating materials. They may work with batt, roll or blown insulation materials.
Typically, only contractors require licenses, not the insulators who work for them. In some states, licensing requirements differ based on the setting. Those with a residential license may work only on residential properties, while those with a commercial license may work on commercial properties. Other states require the same license regardless of the setting, and this report records that license in both settings. Many states have contract minimums before the contractor’s license applies. See Appendix B for details.
