A well-trained crew is essential, both to ensure that the insulation is installed correctly and to meet time and cost objectives.

Every crew should have a lead person responsible for the job. The size of a crew will vary, depending upon the type of blowing equipment and the particular job. A minimum of two people is recommended, even on ceiling jobs done with automatic machines. Where both ceil- ings and sidewalls are to be insulated, it may be advisable to use as many as four people, one of whom must be a competent carpenter. A foreman may be provided on jobs where a single crew consists of four or more men or where more than one crew is working on the same job.
