The fee for this course is included as part of the registration fee, and a link to take the onDemand course will be sent to attendees after registering for the course.
  • A minimum of 3 years of experience in commercial and/or industrial construction, process, and maintenance industry, inspection, or related fields

  • NIA’s Understanding Mechanical Insulation exam is taken on the second day of the course.
  • The exam has 50 questions and will cover information that was discussed in each section.
  • Students must score 70% or higher on the exam to earn their completion certificate.
