Environmental Catch-22: Fire safety chemicals in insulation pose risks
A study in Building Research and Information revealed that plastic foam insulation used to increase energy efficiency in California buildings may pose an unnecessary risk to health and the environment. Manufacturers add potentially harmful fire-retardant chemicals to insulation to pass a flammability test required in building codes. But the test isn't reliable for foam plastic insulation, argued fire scientist Vytenis Babrauskas and his colleagues.
