Bethesda, Maryland -- The Polyisocyanurate Insulation Manufacturers Association (PIMA) claims that polyisocyanurate (polyiso) insulation has has contributed to the reduction of carbon dioxide (CO2) emissions byover 4 million tonnes annually, an amount equivalent to taking 711 000cars off of the road.
PIMA made the claims in a new study that analyses and quantifies the energy and environmental contribution of polyiso insulation over the past 25 years.
"Polyiso insulation has a very positive impact on energy efficiency and the environment," said Jared Blum, PIMA president. "To put it in perspective, on a yearly basis, polyiso reduces the carbon dioxide emissions equal to the energy used in more than 314 000 homes each year or 711 000 cars - that's no small accomplishment."
The study, which was released in conjunction with the 25th anniversary of PIMA, also says that, over the service life of polyiso insulation, the cumulative carbon dioxide emissions reduction would be in excess of 80 million tonnes.
Conducted by TEGNOS Research Inc., the study analyses the environmental contribution of polyiso board insulation from 1987 to 2011 based on an estimate of total shipments from polyiso manufacturers and state-of-the-art energy modelling techniques, PIMA said. The study also calculated the equivalent reduction in energy usage and carbon dioxide based on the various climate regions in the US and the quantity of polyiso.
