Organization
The history of the insulation industry dates back to the late 19th century with the emergence of steam power. Today with energy conservation efforts within the construction industry, the insulation trade is aimed at increasing operational efficiency and reducing fuel costs.

Nature of Trade
The primary work of the trade involves the application of various insulating materials to hot and cold surfaces. Insulation work is generally associated with larger industrial or commercial projects, such as power plants, chemical plants, nuclear power houses, heavy manufacturing or processing installations including refrigeration. Smaller commercial work includes plumbing, heating and air conditioning insulation on such buildings as schools, churches, apartments, shopping centers, hospitals and “tunnel” or “ditch” work.

Formal Training
The primary purpose of the trade is to promote craftsmanship, excellence and safety in the insulation industry. This goal is met through active education and training.
The Apprenticeship program emphasizes on-the-job training and classroom instruction, as well as the use of textbooks and other course materials that give participants a thorough knowledge of the trade. This training is a four-year program in which the participants receive 8,000 hours of on-the-job training with approximately 152 hours each year is in the classroom. The curriculum is developed by the International, and is taught in a classroom and laboratory environment.
