Material Health
Pursuing material health in the building industry involves avoiding or eliminating toxic chemicals from building products. Toxic chemicals are those that can bring harm to factory workers, installers, or building occupants. There are tens of thousands of unregulated chemicals used in our building products, and they can increase the risk of everything from asthma to obesity to cancer.
Materials containing these toxic chemicals include carpet, insulation, wet-applied products like adhesives and sealants, and many others. It’s possible to improve material health through better design decisions and product selections.
