To become an insulation contractor, graduate from high school, complete a training program, and obtain licenses and certifications. Insulation contractors typically work indoors, although they may occasionally work outside insulating oil or gas lines.
Although it is not a strict requirement, a high school or equivalent diploma can increase chances of acceptance into an apprenticeship program or employment for entry-level insulation work. Courses in mechanical drawing, woodwork, geometry, algebra and physics can provide a good base of knowledge for insulation contractors.
Next, complete a formal apprenticeship program, preferably one that combines classroom education and work experience. Requirements for apprenticeship programs may include the ability to carry loads of up to 50 pounds, a valid driver’s license and being at least 18 years old.
Getting certification increases the chances of advancing to supervisory positions. The National Insulation Association offers training and certification for insulation contractors. Many states require contractors to be licensed. The Environmental Protection Agency requires contractors involved in renovating older structures to be licensed when they are working with asbestos. Certified insulation contractors are responsible for calculating potential energy cost savings and determining ideal insulation thickness.
Typical licensing requirements include liability insurance, professional experience and verification of business assets. Many experienced insulation contractors opt to start their own businesses to advance their careers.
