ARLINGTON, Va. — The Polyisocyanurate Insulation Manufacturers Association (PIMA) announces that for the year ending Dec. 31, 2021, polyisocyanurate (polyiso) product shipments increased 7.5% year-over-year as measured in board feet. Over the past five years (2017-2021), total polyiso product shipments have increased by more than 22%. 

“The growth in polyiso shipments tracks the upward trajectory of investments in more energy-efficient commercial and residential buildings,” said PIMA President Justin Koscher. “The public and private sectors are focused now more than ever on policies that reduce building energy use in new construction as well as in the existing building stock. This is creating more opportunities for the use of polyiso insulation in projects that result in significant energy savings, including retrofit projects like roof replacements.” 

PIMA gathers shipment data for polyiso products produced in the U.S. and Canada by the participating manufacturing members of the association. The shipment information is collected and reported in the aggregate by an independent third party, Association Research Inc., and reflects products used for roofs, walls, cover boards and other applications.
