(3) the consumer sector, which is diversified in a manner similar to the. automotive industry, (4) the building industry, which is by far the largest consumer of rigid foams as. insulation materials, and. (5) refrigeration engineering, which represents the second largest area for use of. rigid polyurethane foams as insulation materials.
