Exam Details

The North Carolina Insulation Contractor examination is administered by PSI for the North Carolina Licensing Board for General Contractors. Candidates must complete the applicable licensing or examination-request process and receive examination eligibility before registering and scheduling a testing appointment.

• Classification: Specialty Contractor — Insulation
• Number of questions: 40
• Time allowed: 90 minutes
• Passing score: 70%
• Testing format: Computer-based examination
• Testing provider: PSI Services LLC

The examination content outline includes the following subject areas:

• General Knowledge and Principles: 10 questions
• Liens: 1 question
• Insulation Types and Properties: 15 questions
• Radiant and Reflective Barriers and Vapor Retarders: 7 questions
• Safety: 5 questions
• Laws and Regulations: 2 questions

Insulation types and properties form the largest examination category. Candidates should understand common insulation materials, their thermal characteristics, density, moisture behavior, fire-related properties, suitable applications, installation methods, limitations, handling requirements, and factors that may reduce installed performance.

General knowledge and principles account for ten questions. Preparation should include heat transfer, thermal resistance, conduction, convection, radiation, thermal bridging, air leakage, condensation, moisture movement, climate considerations, building-envelope continuity, ventilation, and the relationship between insulation and other building components.

Radiant and reflective barriers and vapor retarders account for seven questions. Candidates should review how these materials function, where they are installed, the importance of air spaces, vapor movement, permeability, placement, seams, penetrations, fastening, climate considerations, and coordination with other insulation and air-control systems.

Safety accounts for five questions. Insulation work may involve ladders, scaffolds, confined work areas, overhead installation, dust, fibers, chemicals, electrical hazards, sharp tools, heat exposure, personal protective equipment, material storage, and work in attics, crawl spaces, walls, ceilings, and other restricted locations.

Open Book Test

The North Carolina Insulation Contractor examination is an open-book test. Only the two references identified as exam-room approved are included for use inside the testing center. The other three rental books are study-only references and are not permitted inside the examination room.

The North Carolina Occupational Safety and Health Standards for the Construction Industry supports questions involving ladders, scaffolds, respiratory protection, personal protective equipment, fall protection, hazard communication, electrical hazards, tools, material handling, access, housekeeping, and general construction-site safety.

The North Carolina Energy Conservation Code, 2018 Edition supports questions involving insulation values, building thermal envelopes, residential and commercial energy requirements, walls, roofs, ceilings, floors, slabs, crawl spaces, air leakage, air barriers, fenestration, climate zones, vapor retarders, installation requirements, and compliance provisions.

The three study-only books support broader preparation but may not be taken into the testing center. Candidates should use those books to strengthen trade, business, and licensing knowledge while reserving timed exam-room navigation drills for the two approved references.

Approved references may be highlighted, underlined, and indexed before the examination. Tabs must be permanent and firmly attached to the pages. Removable flags, temporary page markers, and Post-it-style tabs are not accepted. Notes may not be written on the tabs.

Loose papers and attached supplemental materials are not permitted. Code materials must be complete and properly bound. Partial copies of an approved reference are not accepted for examination-room use.

The 90-minute testing period provides an average of two minutes and fifteen seconds per question. Candidates should understand the major insulation concepts before test day and use the approved books when a question requires an exact code value, table, definition, installation requirement, or safety standard.

Licensing Steps

Passing the examination does not independently authorize an individual or business to perform licensed contracting work. The applicant or business entity must receive and maintain the applicable North Carolina general contractor license.

State Requirements

The North Carolina Insulation specialty classification covers the installation, alteration, or repair of materials classified as insulating media when those materials are used for the non-mechanical control of temperatures in residential and commercial building construction.

The classification generally applies to insulation installed in walls, ceilings, roofs, floors, crawl spaces, attics, and other building-envelope assemblies. Covered work may involve batt, blanket, loose-fill, blown-in, board, foam, spray-applied, reflective, and other recognized insulation systems.

The classification does not include insulation of mechanical equipment or the ancillary lines and piping connected with mechanical systems. Contractors should ensure that the work they offer remains within the scope of the classification held by the licensed business.

The classification identifies the type of construction work the contractor may perform. The license limitation determines the monetary value of individual projects the contractor may undertake. Applicants should select both according to the business’s intended services, financial qualifications, and anticipated project values.

The applicant must designate a qualifier whose accepted examination supports the Insulation classification. The qualifier demonstrates examination knowledge, while the contractor license is issued to the approved applicant or business entity.

North Carolina generally requires a general contractor license when a person or business undertakes covered construction work valued at $40,000 or more. The licensed entity must hold an appropriate classification and a license limitation that permits the value of the project.

Insulation contractors must also follow applicable permits, inspections, energy-code requirements, building-code provisions, workplace-safety standards, product instructions, project specifications, and other requirements that apply to the work.
