Other information that should be included:

• U-factors of fenestration products
• size and type of apparatus and equipment, and

For blown or sprayed insulation, the initial installed thickness, the settled thickness, the coverage area, and the number of bags must be clearly posted at the job site. In attics, thickness markers must be placed at least once every 300 square feet.
