Polyurethane has been used as a considerably suitable thermal insulator since 1950. Holding very high insulator properties, Polyurethanes result in energy saving and consequently related charges up to %60. Since use of fossil fuels gives birth to about %80 of the world’s carbon dioxide (CO2), therefore, use of polyurethane can be a suitable method for reducing energy consumption and, as a result, reduced CO2 gas as one of the most principal causes of global warming. Moreover, polyurethane insulator while holding higher efficiency in thermal insulation, it is considered lightweight and cost effective compared to other thermal and cold insulators.
